Overview

Our take on the Marantz PM6004

In the PM6004, Marantz uses only the finest ingredients and design chops honed by decades of experience to develop a complex, yet well balanced sonic flavor profile. With all discrete components inside (not a single integrated circuit), the PM6004 reproduces the nuances of your music with stunning clarity and pinpoint placement of instruments across a wide, deep soundstage. A toroidal power transformer means low noise and high current output for breathtaking dynamics and tightly controlled bass. Don't hesitate for a moment to mate the PM6004 with 4-ohm loudspeakers.

Marantz invites you to hear the truth and nothing but the truth. A source direct mode bypasses the tone controls to provide the cleanest signal possible.

GREAT AMP, GREAT PRICE, PHONO INPUT TO BOOT, MATCHED UP WITH THE CD6004 THE SOUND IS HARD TO BEAT, I HAVE IT TIED INTO SOME INFINITY P363'S FANTASTIC SOUND, LOW DISTORTION WITH THE VOLUME TURNED UP HIGH, WILL NEVER USE ALL THE POWER, GREAT UNIT.

Features

2Ch Integrated Amplifier: The Marantz PM6004 is a two-channel integrated amplifier rated at 45 watts x 2-channels into 8-ohms & 60 watts x 2-channels into 4-ohms. 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 PM6004 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 Quality Audio Design: 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.

  • High-Power Output: This unit features a slim-line body, but utilizes a large power supply for dynamic music reproduction with high-power.
  • Symmetrical Circuit Layout: To achieve the best possible sonic performance, signal paths need to be short, direct & mirror imaged. The construction of the integrated amplifier's circuitry provides improved stereo imaging by ensuring close to perfect symmetry between right & left channel layout
  • Shottky Diodes: A Shottky diode is a special type of diode with a very low forward-voltage drop compared to normal diodes. This lower voltage drop translates into higher system efficiency. Shottky diodes have very fast signal handling, can easily stay higher temperatures and are sensitive very low voltages.
  • Toroidal Transformer: A toroidal transformer has several advantages over a normal EI core transformer. It is very efficient & therefore delivers more power compared to the same size of an EI core transformer. In addition, due to its shape, the electromagnetic radiation & the mechanical vibration are extremely low all ending in a better sound quality.

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

Protection Circuit: The integrated amplifier's Protection Circuit is activated in the following situations.

  • If the speaker cable wire touches the rear-panel or screws; or if the speaker cable wire touches the speaker cable's positive & negative sides together.
  • If the surround temperature is extremely high.
  • If the inside of the amplifier gets hot from extended use at a high output.

Auto Standby Mode: With the Auto Standby Mode "On", this unit will automatically enter the Auto Standby Mode after approximately 30 continuous minutes of no output from the speakers or headphones.

Controls

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.

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.

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.

Remote Control: The supplied wireless remote will control the PM6004 & Marantz CD players, DVD players, tuners, or tape decks.

Connections

Gold-Plated Speaker Terminals: The speaker system A & system B outputs are gold-plated binding posts. They are not 5-way posts, but will accept  banana plugs (single/dual), pin connectors, & bare wire.

Gold-Plated Inputs/Outputs: The PM6004 is fitted with gold-plated stereo RCA inputs & outputs.

  • Line Inputs: The CD, Tuner, & Aux/DVD inputs are gold-plated stereo RCA connectors.
  • Recorder: Recorder 1 (CD-R) & Recorder 2 (MD/Tape) have gold-plated stereo RCA inputs/outputs.
  • Phono (MM): The RCA phono input will accept moving magnet (MM) 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.

AC Outlets: The Marantz PM6004 is fitted with two switched & one un-switched AC power outlets to connect your other A/V components.

Power Can Be Pretty

Written by Dave Delamere, Copywriter, on 8/9/2012 11:35:00 AM

The component's sleek finish immediately attracted me, and I was fortunate to be able to sample this Marantz PM6004 integrated amp in my home. I coupled the PM6004 with a pair of Cambridge Audio S70 floor-standing speakers.

It was a classic example of the RMS power number not being representative of what this beauty can do. The numbers say 45 watts RMS per channel, and the speakers can handle 120 watts RMS. I never had to turn the volume past halfway to get amazing depth and detail out of all the music I threw at it. The speakers started to give way to this amp at the higher volumes. So power was not an issue.

Using an NAD C446 digital media tuner as the only source, I played a variety of digital music with higher and mid-level bit rates. The PM6004 delivered great presence and a precise soundstage from both Internet radio stations and the USB thumb drive music I plugged in. Ella never sounded so good, Eddie Van Halen shredded even better than I remembered. It was a wonderful audio experience in a beautiful package.
