Features

Dual-Mono Design: The Marantz Reference Series PM-10 integrated amplifier employs a dual-mono design with separate power supplies for the preamplifier and each of the power amplifier channels, plus one transformer dedicated to the preamp to ensure the delicate signals passing through that section of the amplifier aren't affected by the demands of the high power output stages. There's also a dedicated supply for the microprocessor controlling volume adjustment, input selection and so on, ensuring no noise from the control section finds its way in to the audio path.

Pure Analog Concept: While many other integrated amplifier manufacturers are including digital-to-analog conversion, or adopting digital amplification and volume control, the PM-10 is a purely an analog amplifier - keeping things as clean and simple as possible with its highly-developed all-analog design. Though it may seem convenient to have a DAC in the amplifier, digital circuitry is, by its very nature, noisy (in the electrical sense) and can interfere with the delicate analog signals passing through the amp. That's why Marantz chose to design its Reference Series range with any digital-to-analog conversion in its Super Audio CD or network music players, keeping its amplifiers as pure and clean as possible.

Fully Balanced Layout: The Marantz PM-10 uses a fully balanced layout, from the input section all the way through to the final power amplifier section. By keeping the signal balanced all the way through the amplifier, and combining that with optimized power supply design, the Marantz PM-10 is able to achieve maximum noise rejection throughout the audio path, and the highest possible signal purity.

Bridged Power Amplification: The Marantz PM-10 utilizes bridged power amplification (a total of four amplifier channels) for greater control of your connected stereo loudspeakers. In a conventional amplifier, one speaker is driven by the positive and negative part of one single output stage per channel, but a bridged amplifier does things differently. It uses two separate amplifier stages per channel to drive one speaker, so one amp pushes the speaker cones and domes, while the other pulls them back. As a result, the PM-10 can make the speaker driver units start and stop moving much more precisely for better rhythmic and spatial control, producing voices and instruments that sound more realistic. The PM-10 delivers 200W x 2Ch into an 8Ω load, and can easily cope with demanding speakers or those whose impedance varies widely with frequency, thanks to a 400W x 2Ch output into 4Ω.

Exclusive HDAM (Hyper Dynamic Amplifier Module) Technology: Featuring discrete circuit components, as opposed to an integrated circuit, Marantz's exclusive HDAM technology preserves analog signal purity, delivering wide band audio with expansive dynamic range along with an inaudible noise floor. The PM-10 incorporates the latest-generation HDAM SA3 aided by ultra-fast custom made block capacitors for the fastest possible response to demands for high current and the widest possible frequency and dynamic ranges.

Constant Current Feedback Phono Equalizer: The PM-10 incorporates a constant current feedback phono equalizer developed exclusively by Marantz that supports both MM and MC cartridges. The Phono input terminal is equipped with an input impedance switch for cartridges with high, medium, and low impedances (including 2Ω to 10Ω high-end cartridge) - for optimal performance of a wide variety of phono cartridges.

Copper & Aluminum Constructed Chassis: The PM-10 integrated amplifier is constructed to the highest possible standards, with a double-layered copper-plated chassis for excellent rejection of mechanical and electrical interference, and casework constructed from thick, heavy, non-magnetic aluminum panels. The integrated amp also sits on aluminum machining feet.

Flexible Configuration: The PM-10 provides maximum configuration flexibility, as it can be configured as a conventional stereo integrated amplifier, or set up with another PM-10 as a dual component four channel configuration for bi-amp operation, and it can also be paired with an AV surround processor/pre-amp and used as a stereo power amplifier for the main left and right speakers in a home theater system via the Power Amp Direct inputs.

• Floating Control Bus System: Floating Control Bus System (FCBS) is a two way communication system that enables you to connect up to four PM-11S3s and control them simultaneously, This makes possible a number of applications, including bi-amplifying and multiple channel (surround, multi-channel SACD, etc) applications. A ground loop is not formed between multiple connected PM-10s, therefore sound quality is not adversely affected. When more than one PM-10 is used a different ID code is assigned to each.
• Bi-Amp Mode: Two PM-10s are connected by FCBS in bi-amp mode, enabling each to work as a monaural integrated amplifier.
• Power Amplifier Mode: In this mode, this unit works as a power amplifier. This mode will be useful in home theater systems.

Purest Mode: In Purest Mode, even greater improvements in sound quality are facilitated by cutting off the power supply of circuits (including Recording Output, Non-Signal State Detection, and Headphone) not required when listening to a pair of loudspeakers - giving the audio signal the cleanest possible path through the amplifier.

Balanced & Unbalanced Inputs (including Phono Input): The Marantz Reference Series PM-10 integrated amplifier has two sets of balanced XLR inputs, plus four sets of conventional unbalanced RCA line-level inputs (includes a phono input). Balanced connections guard against induced noise and allow long cable runs without compromising sound quality.

Record Output: Audio signals input into this unit can be output to an external recording device through its stereo RCA record output. When recording audio from a playback device connected to this unit, audio can be recorded with the playback device still connected to this unit.

A & B Speaker Outputs: The A and B speaker outputs are binding posts and will accept single banana plugs, pin connectors, spade lugs (up to 0.575" wide), and bare wire (up to 10 gauge). You can connect one pair of 4-16Ω speakers, two pair of 8-16Ω speakers, or one Bi-Wire pair of 4-16Ω speakers.

Dedicated Headphone Output: Employing Marantz's exclusive HDAM discrete modules, the headphone circuit delivers superb audio fidelity with the widest range of headphone types and impedances, including low impedance headphones. The PM-10 is outfitted with a front-panel 1/4" headphone jack. Plugging in a set of headphones does not automatically turn off the speaker outputs; you will need to turn off the integrate amp's speaker outputs manually.

Front-Panel Display: This PM-10 integrated amplifier features a LCD (Liquid Crystal Display) to display the input source and volume level. Compared with other types of display panels, an LCD requires less drive power and generates less radiation noise, which minimizes any adverse affects on sound quality. The display circuit operation can be turned off to minimize noise from the display and the display circuit which could interfere with the analog audio output signal.

Intuitive Controls: The included IR remote control can also be used to wirelessly operate the PM-10, as well as the matching SA-10S1 SACD player (642SA10S1, sold separately). The PM-10 also features remote control input and output jacks for additional remote control configuration flexibility

• Linear Control Volume: The PM-10 incorporates linear control volume which improve S/N ratio, enabling smooth control in ±0.5 dB steps across a 0 to -100 dB range.
• Balance Levels: The volume level of the left and right channels can be trimmed in 0.5 dB steps across a 0.0 to 9.0 dB range.

Auto Standby Mode: The integrated amplifier will automatically switch to standby mode if the unit is not operated for 30 minutes when there is no audio signal input.

Protection Circuitry: Built-in protection circuitry prevents damage to devices within the power supply when an abnormality such as an overload, excess voltage, or over temperature occurs for any reason. If a malfunction occurs, the power indicator blinks red and the integrated amp switches to standby mode.
