Marantz PM8005 2-Channel Integrated Amplifier

The PM8005 features Marantz HDAM (Hyper Dynamic Amplifier Module) technology, which consists of precision discrete selected circuit elements on a compact sub-board, instead of conventional op-amp integrated circuits. Multiple HDAM units are employed, including HDAM-SA3 and HDAM-SA2 versions that provide gain and buffering functions, to deliver dynamic and detailed sound quality. The PM8005 features current feedback technology for low distortion and wideband response, along with life-like musicality.

The robust power supply features a high-current toroidal main power transformer that is rated at 625VA, providing extra power to the amplifier stage in order to handle demanding short-term peaks. High-current Shottky barrier diodes in the rectification stage are rated at 20 amps, with the ability to handle up to 180 amps peak current, providing sufficient power reserve to handle virtually any loudspeaker load.

The PM8005 is equipped with multiple high-speed, high-current power output devices that are each rated at 14 amps of current output capability, providing a high amount of dynamic headroom, along with compatibility with lower impedance loudspeakers. For optimum heat dissipation, the PM8005 is equipped with solid aluminum power amplifier heat sinks, with a combined total radiating area of 326 square inches, eliminating the need for fans. The PM8005 is rated at 70 W per channel into 8 ohms, and 100 watts per channel into 4 ohms, for compatibility with a wide range of loudspeakers.

For stability and protection from induced vibrations, the PM8005 features a rugged chassis design, which includes a triple-layer bottom plate. To eliminate distortion from stray magnetic fields, the high-current toroidal main power transformer features double shielding.

There are 6 line level inputs to handle a wide range of sources, including a dedicated phono input (MM) that features discrete topology to deliver high fidelity from your favorite vinyl recordings. All inputs and outputs are gold-plated for optimum signal transfer. The Source Direct function bypasses unnecessary circuit blocks for the straightest path from input to the speaker terminals. Pre-amp outputs let you connect a separate stereo power amplifier for a bi-amp loudspeaker system, or for playback in a separate room. The power amp direct input lets you connect the PM8005 to another component, such as a surround sound processor, for integration within a multi-channel home theater system.

For precision tonal balancing, the PM8005 is equipped with a Tri-Tone control system. This includes separate tone controls for the bass, midrange and treble bands, which lets you fine tune the spectral balance to your preference, and is suitable for use with older recordings that suffer from tonal imbalance.

Equipped with audiophile-grade loudspeaker terminals that are designed to accept a wide range of speaker cable termination types, the PM8005 also features A/B speaker switching for increased system configuration flexibility.

The ergonomically designed remote control is equipped with additional functionality, which lets you control a companion Marantz disc player and a Marantz network audio player. Remote control input and output jacks let you directly connect the PM8005 to other Marantz components for easy system control.
