Audio T Verdict
The Marantz CINEMA 70s Series 2 is proof that building a proper surround system does not necessarily mean finding space for a huge AV receiver. At only around 109mm high without its antennas, its slimline chassis is considerably easier to accommodate in a normal living room than most full-size home cinema amplifiers.
That compact construction does involve sensible compromises. Seven discrete Class A/B amplifier channels deliver 50W per channel into eight ohms with two channels driven, so this is not intended to muscle its way through a huge room with difficult loudspeakers at cinema-reference levels.
Within the right system, however, its specification is remarkably comprehensive. Dolby Atmos and DTS:X are supported, six HDMI inputs include three 40Gbps connections capable of 8K/60Hz and 4K/120Hz, while eARC, HDR10+, Dolby Vision, VRR, ALLM and AMD FreeSync provide strong television and gaming compatibility.
The Series 2 model adds a new 32-bit eight-channel digital-to-analogue conversion platform alongside optional Dirac Live room correction, while Audyssey MultEQ XT remains available for straightforward automatic setup.
HEOS Built-in, AirPlay 2, Spotify Connect, TIDAL Connect, Qobuz Connect, Roon Ready support, high-resolution network audio and Bluetooth make the CINEMA 70s Series 2 equally useful for everyday music listening.
Perhaps most importantly, Marantz has retained full 7.2-channel pre-amplifier outputs. That gives the receiver a surprisingly useful upgrade route: external power amplification can be added later if the main speakers or listening room begin to demand more than its compact internal amplifier can comfortably provide.
For smaller and medium-sized rooms where space matters just as much as performance, the CINEMA 70s Series 2 remains one of the most interesting ways to build a genuine surround system without allowing the electronics to dominate the room.

Slimline AV Receiver Design
The defining characteristic of the CINEMA 70s Series 2 is its compact height.
The chassis measures approximately 109mm high without the wireless antennas, making it considerably slimmer than conventional full-size AV receivers.
This makes it particularly suitable for:
- Living-room television systems
- Low-profile AV furniture
- Rooms where a full-height receiver looks intrusive
- Smaller dedicated cinema systems
- Customers moving beyond a soundbar
- Combined music and television systems
The reduced height does not remove the need for ventilation. Seven channels of Class A/B amplification still generate heat and the receiver should not be tightly enclosed inside unventilated furniture.
Who Is the CINEMA 70s Series 2 For?
The CINEMA 70s Series 2 makes most sense where physical space is limited but replacing a proper speaker system with a soundbar is not an acceptable compromise.
It is particularly well suited to efficient standmount or modest floorstanding speakers in small and medium-sized rooms, with an active subwoofer handling the deepest bass.
For larger rooms, demanding loudspeakers or consistently high playback levels, the CINEMA 60DAB Series 2 or CINEMA 50 Series 2 should also be considered.
What Is New on CINEMA 70s Series 2?
The fundamental seven-channel, 50W slimline concept remains familiar, but the Series 2 platform introduces several worthwhile updates.
Key developments include:
- Upgraded 32-bit eight-channel DAC platform
- Dirac Live room-correction upgradability
- 1440p video passthrough
- AMD FreeSync compatibility
- Updated web-based control
- Improved HDMI diagnostic facilities
- Planned Bluetooth LE Audio support through a future firmware update
The result is less a complete redesign of the CINEMA 70s concept and more a modernisation of its digital, calibration and gaming capabilities.
32-Bit Eight-Channel DAC Platform
The Series 2 model introduces Marantz's latest 32-bit eight-channel digital-to-analogue conversion platform.
Multi-channel digital conversion is fundamental to an AV receiver because every decoded speaker channel must ultimately be converted into analogue audio before amplification.
The upgraded platform is intended to improve areas including:
- Resolution
- Low-level detail
- Stereo and surround imaging
- Dynamic expression
- Channel-to-channel consistency
- Spatial coherence
The final result will naturally depend on the complete system, speaker positioning, room acoustics and calibration.
Seven-Channel Discrete Class A/B Amplification
Seven discrete Class A/B power-amplifier channels are built into the CINEMA 70s Series 2.
This allows it to power configurations including:
- 2.0 stereo
- 2.1 stereo with a subwoofer
- 5.1 surround
- 5.2 surround
- 7.1 surround
- 5.1.2 Dolby Atmos
- 5.2.2 Dolby Atmos
A seven-channel receiver cannot independently power four height speakers in addition to conventional five-channel surround speakers.
Maximum Dolby Atmos Layout Is 5.2.2
The CINEMA 70s Series 2 contains seven powered channels and processes a maximum of 7.1 main channels.
For Dolby Atmos, a typical maximum configuration is therefore 5.2.2: front left and right, centre, two surround speakers, two height speakers and up to two subwoofers.
If you are planning four height channels or a substantially larger immersive layout, consider the CINEMA 50 Series 2.
50W Per Channel
Marantz specifies 50W per channel into eight ohms from 20Hz to 20kHz at 0.08% total harmonic distortion with two channels driven.
A separate rating of 70W into six ohms at 1kHz and 0.7% distortion with two channels driven is also published.
The full-bandwidth 50W figure is the more useful reference when comparing conventional Hi-Fi amplifier specifications.
How much amplifier power is actually required will depend on:
- Loudspeaker sensitivity
- Loudspeaker impedance
- Room dimensions
- Listening distance
- Playback level
- Subwoofer crossover settings
- The dynamics of the programme material
Using an active subwoofer and sensible bass management can substantially reduce the low-frequency demand placed on the receiver.
Full 7.2-Channel Pre-Amplifier Outputs
One of the CINEMA 70s Series 2's most useful features is its complete 7.2-channel pre-amplifier output section.
This allows suitable external power amplifiers to be added for any or all of the main channels.
External amplification may be useful where:
- The front speakers are difficult to drive
- The system is used for serious two-channel music
- Greater dynamic headroom is required
- The room is larger than originally anticipated
- A future amplifier upgrade is planned
This makes the CINEMA 70s Series 2 considerably more upgradeable than its small chassis might initially suggest.
Using an External Stereo Power Amplifier
A particularly practical upgrade is to connect a separate two-channel power amplifier to the front left and right pre-amplifier outputs.
The external amplifier then powers the main stereo speakers while the Marantz continues to handle processing and the remaining surround channels.
This can improve headroom with demanding front speakers and may also be useful for customers who place a greater emphasis on music reproduction.
Amplifier gain, input sensitivity and system compatibility should be considered before selecting a power amplifier.
Dolby Atmos
Dolby Atmos allows compatible soundtracks to position audio above as well as around the listening area.
With the CINEMA 70s Series 2, a 5.1.2 or 5.2.2 installation can use two ceiling, height or compatible upward-firing speakers to create the vertical dimension of an Atmos soundtrack.
This can add convincing effects such as:
- Aircraft passing overhead
- Rain extending above the listener
- Ambient room and environmental information
- Greater vertical scale
- Smoother movement between the front and rear of the room
Dolby Atmos Height Virtualization
Atmos Height Virtualization can create a greater impression of vertical sound when physical height speakers cannot be installed.
It uses signal processing through the available conventional speakers to create psychoacoustic height cues.
Properly installed physical height or overhead speakers remain the preferred solution where the room permits them.
DTS:X
DTS:X is also supported for compatible immersive soundtracks.
Like Dolby Atmos, DTS:X allows sound objects to be placed and moved throughout a three-dimensional listening environment rather than being permanently tied to conventional fixed channels.
DTS Neural:X
DTS Neural:X can expand compatible conventional material across a larger installed speaker arrangement.
This can make use of height or additional surround speakers even when the original material is not encoded as a native DTS:X soundtrack.
DTS Virtual:X
DTS Virtual:X provides another virtual-surround option for installations where physical surround or height speakers are limited.
The preferred processing mode will depend on the source material, installed speaker layout and listener preference.
Audyssey MultEQ XT
Audyssey MultEQ XT room correction is built into the CINEMA 70s Series 2.
Using the supplied calibration microphone, the receiver measures the response of the loudspeakers and room from several listening positions.
The setup process establishes parameters including:
- Speaker distance
- Channel level
- Speaker frequency response
- Subwoofer integration
- Crossover behaviour
The automatically generated setup should be treated as a strong starting point rather than something that must never be adjusted.
Audio T recommends checking the resulting speaker-size and crossover settings after calibration.
Audyssey Dynamic EQ
Dynamic EQ helps maintain the perceived balance of bass, treble and surround information when the system is played below cinema-reference level.
This can be particularly useful for normal evening television and movie listening.
Audyssey Dynamic Volume
Dynamic Volume reduces large jumps between quiet and loud material.
It can make late-night viewing easier and reduce abrupt level changes between dialogue, effects and other programme material.
It can be disabled when the complete original dynamic range is preferred.
Optional Dirac Live Room Correction
The CINEMA 70s Series 2 is upgradable for Dirac Live room correction.
This is a significant addition for the slimline model because it provides another route to more detailed acoustic optimisation.
Dirac Live can be particularly useful where:
- The room has difficult acoustics
- Speaker positioning is restricted
- Several seating positions need to be considered
- A customised target response is wanted
- The system has been upgraded beyond a basic AV installation
Dirac Live Is an Optional Upgrade
Dirac Live capability should not be confused with an included full Dirac licence.
The appropriate licence and compatible measurement equipment may need to be purchased separately depending on the calibration package being used.
Check current Marantz and Dirac requirements before purchasing additional software or measurement hardware.
Six HDMI Inputs
Six rear HDMI inputs provide connections for modern digital video sources.
Typical equipment might include:
- Ultra HD Blu-ray player
- Sky or other television receiver
- Apple TV or another streaming player
- PlayStation
- Xbox
- Gaming computer
Three of the six inputs support the receiver's full 40Gbps 8K/60Hz and 4K/120Hz HDMI capability.
Three 40Gbps 8K HDMI Inputs
HDMI inputs 4 to 6 support bandwidth up to 40Gbps for compatible high-resolution and high-frame-rate sources.
These are the connections to prioritise for equipment such as modern games consoles or high-performance gaming computers where 4K/120Hz, 1440p or advanced variable-refresh features may be required.
Not All Six HDMI Inputs Are 8K Inputs
The CINEMA 70s Series 2 has six HDMI inputs in total, but three provide the full 40Gbps 8K/60Hz and 4K/120Hz capability.
Connect high-bandwidth games consoles and other demanding sources to the appropriate HDMI inputs.
The Marantz Setup Assistant and input assignments can then be used to give the source a more convenient on-screen name.
Single HDMI Output with eARC
One main HDMI output connects the CINEMA 70s Series 2 to a television or projector.
The output supports Enhanced Audio Return Channel so compatible television audio can travel back to the Marantz through the same HDMI cable.
Planning a TV and Projector System?
The CINEMA 70s Series 2 has one HDMI monitor output rather than the dual main-room outputs offered by larger Marantz receivers.
If you need to switch routinely between both a television and projector, consider the CINEMA 60DAB Series 2 or CINEMA 50 Series 2, or speak to Audio T about an appropriate HDMI-distribution solution.
eARC Television Audio
eARC allows compatible high-quality television audio to be returned to the receiver through HDMI.
This is useful for:
- Television streaming applications
- Freeview and other internal television tuners
- Sources connected directly to the television
- Dolby Atmos television services
Both the television and receiver must be configured correctly for eARC operation.
8K/60Hz and 4K/120Hz
The high-bandwidth HDMI connections support resolutions up to 8K at 60Hz and 4K at 120Hz.
4K/120Hz is particularly useful for compatible games consoles and PCs, allowing substantially smoother motion than conventional 60Hz video.
8K capability also provides useful compatibility headroom for future sources and displays.
1080p and 4K to 8K Upscaling
The internal video processor can upscale compatible 1080p and 4K HDMI signals for output at up to 8K.
Upscaling cannot recreate real detail absent from the original programme, so it is worth comparing the receiver's processing with the scaling available within the connected television or projector.
HDR10+, Dolby Vision and Dynamic HDR
Modern high-dynamic-range video formats are supported, including:
- HDR
- HLG
- Dolby Vision
- HDR10+
- Dynamic HDR
The complete signal chain, including source, receiver, HDMI cable and display, must support the chosen video format.
1440p Gaming
Series 2 adds improved support for 1440p video.
This resolution is particularly common with gaming computers and can also be useful with compatible games-console configurations.
Native passthrough avoids forcing the source or display to convert unnecessarily between 1080p and 4K.
AMD FreeSync
AMD FreeSync compatibility is provided on HDMI inputs 4 to 6.
With compatible gaming hardware and a suitable display, FreeSync can synchronise the display refresh behaviour more closely to the changing frame rate of a game.
This can help reduce tearing and provide smoother motion.
Variable Refresh Rate
Variable Refresh Rate is also supported for compatible gaming sources and displays.
Rather than forcing the display to refresh at a fixed rate irrespective of game performance, VRR allows compatible hardware to coordinate more dynamically.
Auto Low Latency Mode
ALLM allows compatible gaming equipment to trigger a television's low-latency gaming mode automatically.
This can reduce the amount of display processing between controller input and the corresponding action appearing on screen.
Quick Frame Transport
Quick Frame Transport can reduce transport latency with compatible HDMI equipment by sending each video frame through the connection more quickly.
The feature requires compatible source and display equipment.
HEOS Built-In
HEOS Built-in gives the CINEMA 70s Series 2 comprehensive network music functionality without requiring a separate streamer.
Compatible music services and network sources can be browsed and controlled through the HEOS app.
The platform also allows the receiver to join other HEOS-equipped products in a multi-room music system.
Spotify Connect
Spotify Connect allows music to be selected from the Spotify app while the receiver retrieves the stream directly from the network.
This avoids relying on conventional Bluetooth transmission from the phone for everyday Spotify listening.
TIDAL Connect
TIDAL Connect allows a compatible TIDAL app to select and control music while the receiver handles network playback directly.
Qobuz Connect
Qobuz Connect provides similar direct control from the Qobuz application for compatible playback.
This is particularly useful for listeners who prefer browsing through the native Qobuz application rather than navigating a music service through a separate control interface.
Roon Ready
Roon Ready support allows the CINEMA 70s Series 2 to operate as a network audio endpoint within a compatible Roon system.
A separate Roon subscription and Roon Server are required.
AirPlay 2
Apple AirPlay 2 allows compatible iPhone, iPad and Mac devices to send music wirelessly to the receiver.
The receiver can also participate in an AirPlay 2 multi-room system with other compatible products.
High-Resolution Music Playback
High-resolution music stored on compatible USB or network devices can be played directly through the receiver.
Supported lossless formats include:
- FLAC up to 24-bit/192kHz
- WAV up to 24-bit/192kHz
- Apple Lossless up to 24-bit/192kHz
- DSD at 2.8MHz and 5.6MHz
Gapless playback is supported for compatible FLAC, WAV, Apple Lossless and DSD material.
Bluetooth Audio
Bluetooth allows a compatible phone, tablet or computer to send audio directly to the receiver.
This remains a convenient option for occasional listening or visitors who do not need access to the main HEOS system.
Bluetooth Headphone Transmission
The CINEMA 70s Series 2 can also transmit audio to compatible Bluetooth headphones.
The Bluetooth transmitter has adjustable volume control and provides a useful option for private television or movie viewing.
Future Bluetooth LE Audio Support
Marantz has announced Bluetooth LE Audio support for the Series 2 platform through a future firmware update.
Its lower-latency capabilities are particularly relevant when wireless headphones are being used for television, movies or gaming.
Bluetooth LE Audio Requires Future Firmware Support
Do not assume Bluetooth LE Audio is available immediately on every CINEMA 70s Series 2 installation.
The receiver must have compatible Marantz firmware installed and the connected headphones or mobile device must also support the relevant LE Audio functionality.
Moving Magnet Phono Input
A dedicated moving magnet phono input allows a compatible turntable to connect directly to the receiver without requiring a separate external phono stage.
This makes the CINEMA 70s Series 2 unusually flexible for a compact AV receiver and allows a vinyl source to form part of the same music and television system.
Moving Magnet Cartridges Only
The built-in phono stage is intended for conventional moving magnet cartridge output levels.
A low-output moving coil cartridge will normally require a suitable separate moving coil phono stage or step-up device.
Optical and Coaxial Digital Inputs
One optical and one coaxial digital input provide connections for compatible televisions, CD players, streamers and other digital sources.
These inputs are useful when HDMI is unnecessary or unavailable.
Three Analogue Line Inputs
Three conventional analogue inputs allow legacy and modern line-level equipment to be connected.
Suitable sources might include:
- CD player
- External DAC
- Cassette deck
- Network streamer
- Analogue output from another source component
Zone 2 Audio
The CINEMA 70s Series 2 can provide audio to a second listening zone.
Zone 2 can operate through assigned speaker terminals or the dedicated analogue Zone 2 pre-amplifier output.
Compatible sources include analogue inputs, network audio, USB and two-channel material from suitable optical or coaxial sources.
No HDMI Zone 2 Output
The CINEMA 70s Series 2 provides second-zone audio functionality but does not include a separate HDMI Zone 2 video output.
If independent HDMI video distribution to a second room is required, consider a different receiver or suitable external distribution equipment.
FM Radio Tuner
An integrated FM tuner provides conventional terrestrial radio reception where a suitable aerial signal is available.
Internet radio is also available through the network platform using TuneIn.
Pure Direct Mode
Pure Direct provides a simplified playback route where unnecessary processing and display activity can be reduced.
This can be useful when listening to straightforward two-channel music.
It is worth comparing Pure Direct with correctly calibrated Audyssey or Dirac playback, as room correction and bass management can offer substantial benefits even with stereo music.
Modern HD Graphical Interface
The on-screen graphical interface makes the considerable number of available settings easier to navigate from a connected television.
The Marantz Setup Assistant guides initial configuration rather than expecting the owner to understand every surround, amplifier and HDMI setting immediately.
Smart Select
Smart Select buttons can store combinations of frequently used settings.
A saved configuration can include areas such as:
- Input source
- Volume
- Sound mode
- Audyssey configuration
This is particularly useful where the receiver is regularly switched between television, gaming and music listening.
Web Control
Web-based control allows compatible receiver settings to be accessed through a browser on another device connected to the same network.
This can simplify detailed installation and configuration compared with working exclusively from the front panel or remote control.
HDMI Diagnostics
Built-in HDMI diagnostic facilities can help identify signal-chain problems involving sources, cables, receiver configuration and displays.
This is increasingly useful as HDMI installations combine high resolution, high frame rates, HDR, HDCP and variable-refresh technology.

Should I choose the original CINEMA 70s or Series 2?
The original model may offer excellent value while available at clearance pricing. Series 2 adds the newer DAC platform, Dirac Live upgradability, improved gaming compatibility and the latest control and diagnostic features.
Should I choose CINEMA 70s Series 2 or CINEMA 60DAB Series 2?
Choose the CINEMA 70s Series 2 where compact dimensions are the priority. The CINEMA 60DAB Series 2 provides substantially more amplifier power and greater connectivity for larger or more demanding systems.
Should I choose CINEMA 70s Series 2 or CINEMA 50 Series 2?
Choose the CINEMA 70s Series 2 for a compact seven-channel system. The CINEMA 50 Series 2 is the better choice for larger installations requiring nine internal amplifier channels, 11.4 processing, four subwoofers and greater amplifier output.
