Our take on the Marantz PM5004

Perfect for smaller systems in a den, bedroom, or dorm, the PM5004 lets you experience musical details you never before noticed on your favorite recordings, whether they're on LPs, CDs, or even high-resolution SACDs and DVD-Audio discs in stereo mode. You'll clearly discern the distinct voices of individual musicians, while the ensemble sound remains full and balanced.

Legendary Marantz sound in a modestly powered integrated amp

Perfect for smaller systems in a den, bedroom, or dorm, the PM5004 lets you experience musical details you never before noticed on your favorite recordings, whether they're on LPs, CDs, or even high-resolution SACDs and DVD-Audio discs in stereo mode. You'll clearly discern the distinct voices of individual musicians, while the ensemble sound remains full and balanced.

To maximize audio performance, Marantz's engineers took extensive care with every aspect of the PM5004's design and construction. Audiophiles will appreciate touches like a source direct mode that bypasses the tone controls to provide the cleanest signal possible.

Ample flexibility for connecting your gear

This amp offers six audio inputs, including one for a turntable. Two sets of speaker outputs let you conveniently power a second pair of speakers in another room.

You also get a remote that gives you easy control of the amplifier plus other Marantz audio/video components in your system.

I bought this amp for the sole purpose of using the phono input to push my pro-ject debut carbon turntable, and I am in love with the sound. Wow! Never underpowered, but am only pushing two infinity book shelve speakers. Buy it and love it!

2Ch Integrated Amp: The Marantz PM5004 is a two-channel integrated amplifier rated at 35 watts x 2-channels into 8-ohms and 45 watts x 2-channels into 4-ohms. This unit has a high-quality audio design such as a minimized signal path, use of high sound quality parts, and large power circuits; which is possible only in discrete audio components. The amplifiers themselves are custom-designed entirely with discrete components so you don't suffer any of the built-in limitations of off-the-shelf integrated circuits.

Current Feedback Amplifier: The Marantz PM5004 features current feedback design. This unit uses a high-speed current feedback amplifier circuit for its preamplifier and power amplifier so that signals from the your audio source can be amplified with high fidelity. This extraordinary circuit accurately tracks quickly changing, wide bandwidth musical signals for greater resolution of fine musical detail. The high-speed current feedback amplifier reproduces a natural sound space.

High-Power Output: This unit features a slim-line body, but utilizes a large power supply for dynamic music reproduction with high-power.

Input Buffer Circuit: The integrated amplifier features an input buffer circuit for high signal-to-noise ratio and high channel separation.

Aluminum/Glass-Reinforced Resin Front-Panel: The integrated amplifier's front panel uses a carefully chosen combination of aluminum and glass-reinforced resin to create a distinctive three dimensional appearance. Indirect reflecting blue LEDs indicating input selection, heighten its elegant appearance.


Master Power: A mechanical switch turns the main power on/off. When off, the remote has no effect. When on, the remote can be used to switch between on and standby.

Input Selector: A rotary knob is used to select the input source (Phono, CD, Tuner, AUX/DVD, Recorder 1/2,) for listening.

Tone Control: This unit has a tone control function for adjustment of bass (low frequency) and treble (high frequency) sound to produce your preferred sound.

  • Bass: A rotary knob to adjust the bass output; +/-10 dB @ 100 Hz.
  • Treble: A rotary knob to adjust the treble output; +/-10 dB @ 10 kHz.

Balance: A rotary knob to adjust the left/right balance.

Loudness: The Loudness features compensates for human hearing characteristics by boosting the bass and treble response at low volume levels to achieve a more pleasing tonal balance.

Speakers: These buttons turn the speaker output to the speakers connected to the Speaker System A/B terminals on the rear panel On and Off.

Source Direct: There is a Source Direct switch so you can bypass tone and balance controls for the shortest signal path from input to output. When source direct is engaged the bass, treble, and balance circuits are bypassed.

Remote Control: The supplied wireless remote will control the PM5004 and Marantz CD players, DVD players, tuners, and tape decks.


Speakers: The speaker system A and system B outputs are binding posts. They are not 5-way posts, but will accept  banana plugs (single/dual), pin connectors, and bare wire.

Line Inputs: The CD, Tuner, and Aux/DVD inputs are RCA connectors.

Recorder: Recorder 1 and Recorder 2 have RCA inputs and outputs.

Phono: The RCA phono input will accept moving magnet cartridges. There is a ground terminal beside the phono input.

Remote control: An RCA input and an RCA output are used with other compatible Marantz components using the D.BUS remote system, CD player, DVD player, Tuner, etc. This allows the included remote to control the other Marantz components.

Flasher In: This 3.5mm terminal is to control the unit from another zone with an optional keypad (sold separately).

Headphone: A standard 1/4" headphone jack is on the front panel. The speaker outputs are not automatically muted when you plug in headphones so the speakers must be manually turned off.
