Combining fully discrete current feedback circuitry and our exclusive HDAM technology, the Marantz PM8005 integrated stereo amplifier delivers audiophile grade sound quality along with system operational flexibility. Rated at 70 watts per channel into 8 ohms, the PM8005 features a robust power supply along with high current capability to deliver 100 watts per channel into 4 ohms, for compatibility and operational stability with the widest range of loudspeakers.
The versatile pre-amp section features 6 line level inputs including a phono (MM) input, and the PM8005 also includes pre-amp outputs along with a power amp direct input, which lets you use the unit as a standalone power amplifier for integration into a multi-channel home theater system. For precise sound tailoring, the PM8005 features our triple tone control system, with separate controls for the bass, midrange and treble segments. The elegant remote control features an ergonomic layout for easy operation, and includes the ability to control our companion SA8005 disc player and one of our network players.
The PM8005 features our exclusive 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 ultra low distortion and wideband response, along with superb musicality.
The robust power supply features a high current toroidal main power transformer that is rated at 625VA, to easily provide 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 very 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 conservatively rated at 70 watts per channel into 8 ohms, and 100 watts per channel into 4 ohms, for compatibility with the widest range of loudspeakers.
For the utmost 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.
