Performance Specs

One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements.The Marantz Model 50 is rated at 70 watts RMS into 8-ohms. Marantz provides this wattage at a THD (Total Harmonic Distortion) of 0.02% which is an important indicator of distortion at the given values (lower THD is better).

Here are the main highlights of its performance specs:

  • 70 watts into 8-ohms (20-20k) at 0.02%
  • 100 watts into 4-ohms
  • 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
  • 113dB Signal to Noise Ratio

When pairing the Marantz Model 50 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.

Bluetooth Connectivity

Marantz Model 50 doesn't have bluetooth connectivity feature. In order to stream your music via bluetooth, the easiest way is to connect an external bluetooth receiver to your Marantz Model 50. Two bluetooth receivers that we recommend are the iFi Zen Blue V2 and the Audioengine B1.

Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:

  • NAD C 368 BluOS-2i - MSRP 1749$ - Compare w/ Model 50
  • JBL SA550 C - MSRP 1999$ - Compare w/ Model 50

Phono Input

Marantz Model 50 features one Phono Input which is compatible with MM (Moving Magnet) type of phono cartridges, you can connect your turntable with MM cartridges directly to this amp without the need for a phono preamp. If you are using an MC cartridge on your turntable, you need to use a phono preamp that has MC phono stage such as the Cambridge Duo or the iFi ZEN Phono.

Marantz Model 50 has a dedicated subwoofer output which can be used to connect it directly to a powered subwoofer via an LFE(Low Frequency Effects) cable.
