Description
Marantz CINEMA 50 Series 2 9.4-Channel AV Receiver
The Marantz CINEMA 50 Series 2 is a serious nine-channel AV receiver for purpose-built home theatre systems, combining 110W-per-channel amplification, 11.4-channel processing, six 8K HDMI inputs, four independent subwoofer outputs, HEOS streaming and advanced room-correction options in Marantz's full-size CINEMA chassis.
Series 2 keeps the layout that made the CINEMA 50 a useful system-building receiver, but updates the digital section with a new 32-bit DAC platform. The result is a receiver that can run a substantial surround system on its own, while still giving you the pre-outs, control connections and calibration tools needed when the room or speaker package grows.
Nine Amplified Channels, 11.4-Channel Processing
A receiver that can start complete and grow with the room
CINEMA 50 Series 2 has nine onboard power-amplifier channels rated at 110W per channel into 8 ohms with two channels driven. In practical theatre layouts, that makes 5.1.4 and 7.1.2 systems straightforward without immediately adding separate power amplification.
The processing stage extends to 11.4 channels and Marantz provides full 11.4-channel pre-outs. If the room later moves to a 7.1.4 layout, an external two-channel power amplifier can take care of the additional pair while the receiver remains the control centre. This is the sort of upgrade path worth planning before the walls close up: speaker wiring for the larger layout is inexpensive during construction and considerably less enjoyable afterwards.
Four Independent Subwoofer Outputs
Better bass planning for more than one seat
Four independent subwoofer outputs give the installer much more freedom than a simple duplicated subwoofer feed. Multiple subs are not just about producing more bass; correctly positioned and calibrated, they can reduce large seat-to-seat variations and make the low end more consistent across a wider listening area.
The right number and position of subwoofers depends on the room, seating layout and construction. For a dedicated theatre, this is an area where a little planning usually delivers a larger improvement than chasing another headline wattage figure.
Audyssey MultEQ XT32 and Dirac Live Upgrade Support
Two routes to room correction
Audyssey MultEQ XT32 is included for speaker setup, level matching, distance correction and room EQ, together with Dynamic EQ and Dynamic Volume. That gives the receiver a capable calibration path straight out of the box.
Dirac Live is also supported as an upgrade. For customers who want to go further with measurement and target-curve control, Dirac provides another route to integrating the speakers and room. Treat room correction as the finishing stage rather than a cure for poor placement: sensible speaker locations, subwoofer positioning and basic room behaviour still matter.
Six 8K HDMI Inputs
Ready for current consoles, media players and high-bandwidth video
All six rear HDMI inputs support 8K/60Hz and 4K/120Hz pass-through at up to 40Gbps, with eARC, HDR10, HDR10+, Dolby Vision, HLG and Dynamic HDR. Gaming support includes VRR, ALLM and Quick Frame Transport, with AMD FreeSync compatibility.
There are three HDMI outputs, including a Zone 2 output, which is useful in systems feeding a projector and television or a second video zone. HDMI diagnostics and web control are also included, both genuinely useful tools when the receiver is installed in cabinetry or a remote equipment rack.
Immersive Audio and Marantz Processing
Dolby Atmos, DTS:X, Auro-3D and IMAX Enhanced
The format list covers Dolby Atmos, DTS:X, Auro-3D and IMAX Enhanced, along with Dolby Surround, DTS Neural:X, DTS Virtual:X, 360 Reality Audio and MPEG-H. DTS:X Pro is not supported on this model, so customers building unusually large DTS:X speaker layouts should account for that distinction.
Marantz's current-feedback topology and HDAM-SA2 circuitry sit alongside the discrete power-amplifier stage. The useful takeaway is not the parts list by itself; it is that the CINEMA 50 Series 2 is designed to handle both cinema and two-channel listening without treating music playback as an afterthought.
HEOS, Roon Ready and Everyday Music
The receiver can be the main music source too
HEOS Built-in provides network streaming and multi-room control, with AirPlay 2, Spotify Connect, TIDAL Connect, Qobuz Connect, internet radio and high-resolution local playback. Roon Ready support makes it easier to fold the receiver into a more developed whole-home or library-based music system.
The analogue side is still well covered, including five analogue inputs, a moving-magnet phono input, two optical and two coaxial digital inputs. Bluetooth transmission can send the receiver's audio to compatible Bluetooth headphones when quieter late-night listening is needed.
Installation and System Planning
Give a full-size AVR the room it needs
This is a 13.5kg full-size receiver, approximately 442mm wide and 392mm deep without antennas. It should not be squeezed into a sealed shelf. Leave sensible ventilation around the chassis and account for the extra depth of HDMI plugs, speaker cable and interconnects behind it.
RS-232, IP control, web control, IR flasher input, Marantz Remote Bus and a 12V trigger output make the CINEMA 50 Series 2 suitable for integrated control systems as well as normal living-room installations. If you are planning external power amplifiers, multiple subwoofers, a projector plus television, or a second zone, talk to us before cabling so the receiver's flexibility is actually reflected in the wiring.

The Audio Experts Take
The CINEMA 50 Series 2 sits in a very useful part of the Marantz range. Nine onboard channels are enough for the layouts most serious living rooms and many dedicated theatres actually use, while 11.4 processing and full pre-outs mean the receiver does not become a dead end when the system grows.
The four independent subwoofer outputs, Audyssey XT32, optional Dirac path and proper control connections are the features we would pay attention to before the headline power figure. They give you much more scope to make a difficult room behave and to integrate the receiver cleanly into a complete installation.
If you are choosing speakers, subwoofers and external amplification at the same time, talk to us about the whole layout rather than trying to match everything from isolated specifications. Getting the channel plan, ventilation, cabling and bass strategy right at the start is where a receiver like this earns its flexibility.
