The Cinema 70s is a home theater receiver by Marantz. It is a 7-channel design using a AB output stage. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. It also has a phono input, so a turntable can connect straight to it. The Marantz Cinema 70s has an MSRP of $1,300.
Marantz later replaced the Marantz Cinema 70s with the Marantz Cinema 70s Series 2. Follow the link to read our in-depth comparison of these speakers:

Performance Specs
One of the most important factors when deciding on a home theater receiver is its power ratings and compatibility with your speaker's impedance requirements. The Marantz Cinema 70s is rated at 50 watts RMS into 8-ohms (2 channels driven).
Here are the main highlights of its performance specs:
- 50 watts into 8-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)

Need more power?
Marantz Cinema 70s is rated at 50 watts into 8 ohms, which puts it in our Up to 60 watts band. The next band up is 61 to 90 watts, which is worth about 3.9dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room.
When pairing the Marantz Cinema 70s with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
Inputs and Outputs
Besides the performance specs of the Marantz Cinema 70s, the next important feature set that you have to evaluate is the input and output selections that it offers.
Marantz Cinema 70s has total of 3 Analog inputs .
Inputs
- Total Number of Analog Inputs: 3
- Phono Input
- 1 Optical Digital Input
- 1 Coaxial Digital Input
- USB Input
Outputs
- Speaker Outputs
- 7.2-channel Preamp Outputs
- Subwoofer Output (Dual)
- HDMI Output (1)
Surround Sound and Channels
Marantz Cinema 70s is a 7.2-channel receiver, powering 7 speakers directly - the .2 is 2 subwoofer outputs, not extra amplified channels. It decodes Dolby Atmos, DTS:X.
Video and HDMI
An AV receiver is the switch every source passes through on its way to the
television, so what it can carry sets a ceiling on the rest of the system.
- Pass-through: 8K/60Hz, 4K/120Hz
- HDMI version: 2.1
Room Correction
Marantz Cinema 70s includes
Audyssey MultEQ.
Room correction measures the speakers where they actually stand and corrects
for what the room does to them, which in a multi-channel system matters more
than in a stereo one - the surround and height channels are usually the ones
placed where they fit rather than where they should be.
Marantz Cinema 70s Pros and Cons
Drawn from the published figures on this page, not from listening.

- ✓Video passthrough at 8K/60Hz, 4K/120Hz.
- ✓Decodes Dolby Atmos and DTS:X.
- ✓Room correction: Audyssey MultEQ.
- ✓Subwoofer outputs: Dual - more than one sub is the cheapest route to even bass in a real room.
- ✓Has a phono input, which most receivers at any price no longer bother with.
- ✗The 50-watt rating is measured with two channels driven; expect less with every channel working, which is how a receiver actually runs.
