Audio T Verdict
The Marantz CINEMA 50 Series 2 takes one of the sweet spots in the CINEMA range and brings its digital platform properly up to date without losing the flexibility that made the original CINEMA 50 such a capable home cinema centrepiece.
Nine discrete power-amplifier channels provide 110W per channel into eight ohms with two channels driven, while 11.4-channel processing gives the CINEMA 50 Series 2 enough flexibility to build anything from a conventional 5.1 system to a serious immersive setup with additional height channels and multiple subwoofers.
The big Series 2 change is its new 32-bit eight-channel digital-to-analogue conversion platform. This is joined by Dolby Atmos Channel Expander, Centre Bi-Amp Mode, enhanced gaming support including 1440p and AMD FreeSync, plus improved installation and diagnostic tools.
Room correction is particularly comprehensive. Audyssey MultEQ XT32 and Sub EQ HT are provided for straightforward automatic calibration, while Dirac Live gives enthusiasts another route for more detailed room optimisation. Four independently adjustable subwoofer outputs make the CINEMA 50 Series 2 especially interesting for more ambitious systems.
Six HDMI inputs, three HDMI outputs, 8K/60Hz and 4K/120Hz compatibility, eARC, HEOS Built-in, AirPlay 2, Bluetooth and high-resolution network playback mean it is equally comfortable handling films, television, gaming and music.
For customers who want a genuinely serious surround system without immediately stepping into separate AV processing and power amplification, the CINEMA 50 Series 2 is arguably one of the most versatile places to start in the current Marantz range.

What Is New on the CINEMA 50 Series 2?
The CINEMA 50 Series 2 develops the established CINEMA 50 platform rather than replacing its fundamental approach.
The principal Series 2 developments include:
- New 32-bit eight-channel digital-to-analogue conversion platform
- Dolby Atmos Channel Expander
- Centre Bi-Amp Mode
- 1440p video passthrough for gaming
- AMD FreeSync compatibility
- Web Control 2.0
- HDMI Diagnostics 2.0
- Planned Bluetooth LE Audio support through a future firmware update
The objective is not simply to add more formats to the specification sheet. The updated platform is designed to improve conversion across multiple channels while adding useful flexibility for modern immersive speaker systems, gaming and professional installation.
New 32-Bit Eight-Channel DAC Platform
A major Series 2 development is the adoption of a new 32-bit eight-channel digital-to-analogue conversion platform.
Its multi-channel architecture is designed to provide simultaneous high-resolution conversion across the surround system rather than treating individual channels as secondary to the main left and right outputs.
Marantz has designed the new implementation to improve:
- Low-level detail
- Spatial precision
- Image placement
- Dynamic expression
- Coherence between surround channels
- Consistency throughout the listening area
As with any AV receiver, the final audible result will also depend on the speakers, room acoustics, calibration and source material.
Nine-Channel Discrete Power Amplification
The CINEMA 50 Series 2 contains nine discrete power-amplifier channels rather than relying on an external power amplifier for a conventional nine-speaker installation.
Each amplifier channel uses a discrete high-current design intended to maintain consistent performance across the complete surround system.
This allows configurations such as:
- 5.1-channel surround
- 7.1-channel surround
- 5.1.2 Dolby Atmos
- 5.1.4 Dolby Atmos
- 7.1.2 Dolby Atmos
- Equivalent layouts using multiple subwoofers
More advanced layouts can be created by using the CINEMA 50 Series 2's additional processing channels with suitable external power amplification.
110W Per Channel
Marantz specifies 110W per channel into eight ohms from 20Hz to 20kHz at 0.08% total harmonic distortion with two channels driven.
This is an important measurement condition. It should not be interpreted as nine simultaneous channels each continuously producing 110W from the shared power supply.
Real-world power requirements vary considerably according to:
- Speaker sensitivity
- Speaker impedance
- Listening distance
- Room size
- Subwoofer crossover settings
- Required playback level
- The dynamics of the soundtrack
Using active subwoofers and appropriate bass management can substantially reduce the low-frequency workload placed on the receiver's main amplifier channels.
11.4-Channel Processing
Although nine power-amplifier channels are built into the receiver, the CINEMA 50 Series 2 can process up to 11.4 channels.
This creates considerably more system flexibility than the amplifier count alone might suggest.
With suitable external power amplification, the additional processing can be used to create layouts with more surround or height speakers, including configurations extending beyond the nine internally powered channels.
Eleven Processing Channels Does Not Mean Eleven Built-In Power Amplifiers
The CINEMA 50 Series 2 contains nine internal power-amplifier channels.
If a speaker layout requires more than nine simultaneously powered passive speakers, suitable external power amplification will also be required.
Speak to Audio T if you are planning an 11-channel installation so that amplifier assignment, pre-amplifier outputs and speaker layout can be considered together.
Four Independent Subwoofer Outputs
Four subwoofer outputs give the CINEMA 50 Series 2 considerably more bass-management flexibility than a conventional single or dual-subwoofer receiver.
Multiple subwoofers are not simply about producing more bass.
Correctly positioned and calibrated multiple subwoofers can help:
- Reduce large bass peaks and nulls
- Provide more even low-frequency coverage across several seats
- Increase available headroom
- Reduce the workload placed on an individual subwoofer
- Improve integration between the speakers and room
The CINEMA 50 Series 2 can adjust level and delay independently for each of its four connected subwoofers.
Audyssey Sub EQ HT
Audyssey Sub EQ HT is designed to help integrate multiple subwoofers before the wider MultEQ XT32 correction process is applied.
It first compensates for level and delay differences between connected subwoofers and then allows MultEQ XT32 to perform further room correction.
This is particularly useful where subwoofers occupy different positions within the room and therefore arrive at the listening area with different timing and output characteristics.
Audyssey MultEQ XT32
Audyssey MultEQ XT32 is built into the CINEMA 50 Series 2 and provides automatic speaker and room calibration using the supplied measurement microphone.
The calibration process analyses the interaction between the loudspeakers, subwoofers and room from several listening positions.
It can then establish and optimise parameters including:
- Speaker distances
- Channel levels
- Frequency response
- Crossover behaviour
- Subwoofer integration
- Time-domain response
Automatic calibration provides a very useful starting point, although Audio T recommends checking the resulting speaker sizes, crossover points and subwoofer settings rather than assuming that every automatically selected value will be ideal for every system.
Audyssey Dynamic EQ
Dynamic EQ is intended to maintain perceived tonal balance and surround detail when listening below cinema-reference volume.
Human hearing becomes less sensitive to bass and high frequencies as volume is reduced. Dynamic EQ compensates for this behaviour while also maintaining surround-channel balance.
It can be particularly useful for normal evening television and film viewing where full reference-level playback is neither necessary nor practical.
Audyssey Dynamic Volume
Audyssey Dynamic Volume can reduce large changes in playback level between quiet and loud material.
This can make late-night viewing more comfortable and can also help with programmes or broadcasts where dialogue, adverts and effects vary considerably in level.
For unrestricted movie dynamics, the function can be switched off.
Audyssey LFC
Audyssey Low Frequency Containment is designed for situations where deep bass travelling through floors and walls may disturb neighbouring rooms.
The processing reduces the low-frequency content most likely to travel through the structure while using psychoacoustic processing to preserve the listener's perception of bass within the room.
It can be useful in flats, shared buildings and late-night listening environments.
Dirac Live Room Correction
The CINEMA 50 Series 2 also supports Dirac Live room correction, giving owners an alternative calibration platform for more detailed optimisation of the system and listening room.
Dirac analyses both frequency and time-domain behaviour and can be particularly valuable where:
- The room has difficult acoustic characteristics
- Several listening seats need to be accommodated
- Speaker positioning is constrained
- More detailed control of the target response is wanted
- The system justifies more involved calibration work
Current licensing, measurement-hardware requirements and availability of optional advanced Dirac features should be checked before setup.
Audyssey or Dirac Live?
Audyssey MultEQ XT32 provides a straightforward and highly capable route to automatic calibration using the supplied Marantz microphone.
Dirac Live is likely to appeal more strongly to customers who want to spend additional time measuring, analysing and tailoring the system.
Neither removes the importance of sensible speaker and subwoofer positioning. Audio T can help determine which approach best suits the room and the level of system being installed.
Dolby Atmos
Dolby Atmos moves beyond a fixed channel-based surround system by allowing compatible soundtracks to position audio objects within a three-dimensional listening space.
With suitable height or overhead speakers, effects can move above as well as around the listener.
This can reproduce:
- Aircraft moving overhead
- Rain extending above the seating position
- Ambient information around the complete room
- More precise movement between speakers
- A greater sense of vertical scale
The final result depends heavily on speaker layout and calibration, so adding more channels is not automatically preferable to installing fewer speakers correctly.
Dolby Atmos Channel Expander
Dolby Atmos Channel Expander is one of the notable additions to the CINEMA 50 Series 2.
When compatible Dolby Atmos material does not contain information for every speaker available within an installed system, Channel Expander can synthesise additional information from adjacent channels so that more of the available speaker layout can be used.
This is particularly relevant to larger immersive installations where some height or surround speakers might otherwise remain inactive with certain Atmos mixes.
The feature can be switched according to the source and listener preference rather than permanently changing the original soundtrack.
Dolby Speaker Virtualizer
Speaker Virtualizer can create a greater impression of surround and height information when the physical speaker installation is more limited.
This allows customers without a complete overhead-speaker installation to gain a more immersive presentation from compatible material.
Physical speakers installed in appropriate locations remain the preferred solution where the room and budget allow.
DTS:X
DTS:X is another object-based immersive audio format supported by the CINEMA 50 Series 2.
Rather than tying every sound permanently to a fixed channel, DTS:X allows compatible content to position and move sound objects around the listening environment according to the available speaker configuration.
DTS Virtual:X
DTS Virtual:X can create a greater perception of surround and height from speaker layouts without physical height channels.
It provides another option for living rooms where installing ceiling, height or additional surround speakers is impractical.
Auro-3D
Auro-3D is supported for customers building a compatible height-layer speaker arrangement.
Auro-3D uses conventional ear-level speakers together with additional height channels to create a vertically layered sound field.
Speaker positioning requirements differ from some Dolby Atmos configurations, so customers intending to use both formats should plan the installation before running cables or mounting speakers permanently.
IMAX Enhanced
IMAX Enhanced combines compatible picture and DTS-based audio processing intended to reproduce specially prepared IMAX Enhanced content within a suitable home cinema system.
The benefit depends on compatible programme material as well as the complete display, speaker and subwoofer system.
Centre Bi-Amp Mode
Centre Bi-Amp Mode is another new CINEMA 50 Series 2 feature intended for compatible centre-channel loudspeakers.
Where the centre speaker provides separate high-frequency and low-frequency terminals and is suitable for passive bi-amplification, separate amplifier channels can be assigned to its crossover sections.
The centre channel carries a large proportion of dialogue and front-screen information in many film mixes, making its performance particularly important to a convincing home cinema system.
Bi-Amp Connections Must Be Made Correctly
A centre speaker must be specifically suitable for passive bi-amplification before Centre Bi-Amp Mode is used.
The terminal links between the high-frequency and low-frequency sections must be removed before separate amplifier channels are connected.
Incorrect wiring can connect amplifier outputs together and may cause damage. Speak to Audio T before using this configuration if you are unsure.
Six HDMI Inputs
Six HDMI inputs provide connections for a wide range of modern digital sources.
These might include:
- 4K Ultra HD Blu-ray player
- Games console
- Streaming video player
- TV set-top box
- Media server
- Computer
Input assignments can be configured through the receiver rather than every source being permanently tied to the label printed beside the HDMI socket.
Three HDMI Outputs
The CINEMA 50 Series 2 provides three HDMI outputs.
Two outputs are available for the main room, allowing installations using two displays such as a television and projector.
A separate HDMI Zone 2 output can send a compatible source to another display in a second room.
8K/60Hz and 4K/120Hz Video
The HDMI platform supports video resolutions up to 8K at 60Hz and 4K at 120Hz with compatible sources, displays and cables.
4K/120Hz is particularly relevant to current games consoles and suitably equipped gaming computers because the higher frame rate can provide smoother motion and reduced perceived latency.
8K compatibility also provides useful headroom for future video sources even where the present system is based around a 4K television or projector.
Use the Correct HDMI Cable
For 8K and 4K/120Hz signals, use a certified Ultra High Speed HDMI cable suitable for the required bandwidth.
A cable that works successfully with conventional 1080p or 4K/60Hz material is not automatically capable of passing higher-bandwidth video reliably.
Intermittent picture loss, flashing, reduced resolution or loss of HDR can all result from an unsuitable or excessively long HDMI cable.
1080p and 4K to 8K Upscaling
The internal video processor can upscale suitable 1080p and 4K material for output at up to 8K resolution.
Upscaling creates the pixel structure required by the receiving display but cannot manufacture genuine detail that does not exist within the original source.
It is worth comparing the receiver's processing with that of the television or projector, as the preferred result may vary according to the display being used.
HDR Video
The CINEMA platform is designed to pass modern high-dynamic-range video formats from compatible sources to a suitable television or projector.
HDR compatibility is only one part of the signal chain. The source, receiver, HDMI cable and display must all support the required format and bandwidth.
eARC Television Audio
Enhanced Audio Return Channel allows a compatible television to send high-quality audio back to the CINEMA 50 Series 2 through the same HDMI connection used to send video to the television.
Unlike conventional ARC, eARC can support higher-bandwidth formats including:
- Multichannel linear PCM
- Dolby TrueHD
- Dolby Atmos
- DTS-HD
- DTS:X
This is particularly useful when streaming applications are built into the television or when a source is connected directly to the television.
1440p Gaming Support
The Series 2 video platform adds support for 1440p passthrough.
1440p is widely used by gaming computers and some games-console configurations, sitting between conventional 1080p and 4K resolution.
Native support helps avoid unnecessary resolution conversion when the source and display are both configured for 1440p operation.
AMD FreeSync
AMD FreeSync compatibility has also been added for compatible gaming equipment.
Variable synchronisation between the source and display can help reduce screen tearing and maintain smoother motion when the game's frame rate changes.
The games system, CINEMA 50 Series 2 and display must all be configured appropriately for the feature being used.
HEOS Built-In
HEOS Built-in turns the CINEMA 50 Series 2 into a network music player as well as an AV receiver.
Through the HEOS app, compatible online services, internet radio and music stored elsewhere on the home network can be accessed without requiring a separate streamer.
HEOS can also form part of a compatible multi-room audio system, allowing music to be grouped with other HEOS-enabled products around the home.
AirPlay 2
Apple AirPlay 2 allows compatible iPhone, iPad and Mac devices to send audio wirelessly to the receiver.
It also enables the CINEMA 50 Series 2 to participate in an AirPlay 2 multi-room system alongside other compatible products.
High-Resolution Network Audio
The CINEMA 50 Series 2 can play high-resolution digital music from compatible network and USB sources.
Its published capabilities include FLAC files up to 192kHz and DSD at up to 5.6MHz.
This allows the receiver to perform double duty as the main music source in many systems rather than being restricted to film and television playback.
USB Music Playback
A USB connection allows compatible music stored on USB mass-storage media to be played through the receiver.
The source can then benefit from the CINEMA 50 Series 2's internal digital conversion, bass management and chosen listening mode.
Bluetooth Audio
Bluetooth reception allows compatible phones, tablets and computers to send music directly to the CINEMA 50 Series 2.
Bluetooth is particularly convenient for quick, informal playback where app-based network streaming is unnecessary.
For critical listening, HEOS, AirPlay 2 or wired/network high-resolution playback may provide greater capability depending on the source service and material.
Bluetooth Headphone Transmission
The CINEMA 50 Series 2 can also transmit audio to compatible Bluetooth headphones.
This is useful for private or late-night viewing without running a headphone cable across the room.
Bluetooth headphones can be used on their own or, in compatible operating modes, alongside the connected loudspeakers.
Bluetooth LE Audio
Marantz has announced low-latency Bluetooth LE Audio support for the Series 2 platform through a future firmware update.
The reduced wireless delay can be particularly useful when Bluetooth audio is being used with television, films or gaming because picture and sound need to remain closely synchronised.
Bluetooth LE Audio Requires a Firmware Update
Bluetooth LE Audio is a planned Series 2 feature rather than something that should be assumed to be active on every unit from first installation.
Keep the CINEMA 50 Series 2 connected to the network and install current Marantz firmware before attempting to use the feature.
The headphones or mobile device must also support the relevant Bluetooth LE Audio functionality.
Web Control 2.0
Web Control 2.0 provides browser-based access to receiver configuration from a compatible computer, phone or tablet on the same network.
This can make detailed setup considerably easier than working through every option using the receiver's front display and remote control.
It is also particularly useful for system installers who need to configure and verify a large number of settings efficiently.
HDMI Diagnostics 2.0
HDMI Diagnostics 2.0 provides additional information for identifying HDMI connection and compatibility problems.
Modern HDMI systems can involve source resolution, frame rate, HDR format, HDCP, cable bandwidth and display-handshake considerations simultaneously.
Better diagnostic information can therefore make it considerably easier to identify whether a problem sits with the source, cable, receiver settings or display.
Marantz Setup Assistant
When initially connected to a television, the Marantz Setup Assistant provides step-by-step on-screen guidance.
It helps configure areas including:
- Speaker connections
- Speaker layout
- Subwoofer configuration
- Source connections
- Television connection
- Network setup
- Room calibration
This makes the CINEMA 50 Series 2 considerably less intimidating than its large number of rear-panel connections might initially suggest.
Speaker Assignment Flexibility
The amplifier channels can be assigned to different speaker duties according to the intended installation.
This allows the receiver to accommodate different combinations of:
- Surround-back speakers
- Height speakers
- Overhead speakers
- Bi-amplified compatible speakers
- Additional zones
- External power amplification
The correct Amp Assign configuration should be established before calibration so the receiver knows exactly which speakers are connected and which amplifier channels are being used.
Adding an External Power Amplifier
The CINEMA 50 Series 2's 11.4-channel processing makes external power amplification useful for more ambitious systems.
An external power amplifier may be considered when:
- More than nine passive speaker channels need to operate simultaneously
- The main front speakers are particularly demanding
- The room is large
- Higher sustained playback levels are required
- The system is being upgraded gradually towards separates
Moving selected channels to an external amplifier can also reduce the workload placed on the receiver's internal amplification.
Using the CINEMA 50 Series 2 with a Stereo Power Amplifier
A practical upgrade route is to use a suitable two-channel power amplifier for the main front left and right speakers while the Marantz continues to power the remaining channels.
This can provide additional headroom for the main speakers while also making the two additional processing channels available for a larger immersive installation.
Power-amplifier gain, input sensitivity and overall system matching should be considered before purchase.
Music Playback
The CINEMA 50 Series 2 is not limited to movie soundtracks.
Its network streaming, high-resolution file support, two-channel listening modes and Marantz audio engineering mean it can serve as the main amplifier for both music and home cinema in a shared system.
Customers placing particularly high importance on two-channel music should compare the result with a dedicated stereo amplifier or consider integrating suitable external stereo amplification.
Pure Direct Listening
Pure Direct operation can reduce unnecessary processing when a simpler signal path is preferred for compatible sources.
Whether this sounds preferable to calibrated playback will depend on the source, loudspeakers, subwoofer integration and room acoustics.
In many rooms, the benefits of good room correction and bass management can outweigh the theoretical advantage of bypassing processing.
Multi-Room Audio and HDMI Zone 2
Zone functionality allows the CINEMA 50 Series 2 to form part of a larger whole-home installation.
The separate HDMI Zone 2 output can send compatible audio and video to another room while the main system is in use.
HEOS provides an alternative route for network-based multi-room music with compatible products.
Front Headphone Connection
A conventional wired-headphone socket is provided on the front panel.
Connecting headphones disables normal output from the connected speakers and main pre-amplifier outputs.
Reduce the volume before connecting headphones and establish a safe listening level gradually.

Ventilation and Equipment-Rack Positioning
A nine-channel AV receiver produces considerably more heat than a typical source component.
The CINEMA 50 Series 2 should therefore be installed on a stable surface with sufficient airflow around the chassis.
Avoid:
- Enclosing the receiver tightly inside an unventilated cabinet
- Blocking the upper ventilation openings
- Placing equipment directly on top of the receiver
- Installing it close to a radiator or other heat source
- Allowing cables to obstruct ventilation
For enclosed furniture or custom installations, active ventilation may be worth considering.
