Краткое описание товара

Marantz Current Feedback Discrete Power AmplifierInstead of employing conventional voltage-based feedback in the power amplifier section, the PM7005 features current feedback, which is designed to deliver optimized fidelity and low distortion. The amplifier section consists of all discrete circuitry (no op-amps), and features high-current discrete power output devices that provide high instantaneous peak current capability, and the PM7005 is rated at 60W per channel into 8 ohm loads and 80W per channel into 4 ohm loads.Wide Range of Connectivity OptionsThe PM7005 is equipped with numerous analog inputs, including recording inputs and outputs, and features coaxial and optical digital inputs, along with a USB-B 2.0 asynchronous input for high resolution computer audio files.Advanced Digital-to-Analog Conversion with PCM and DSD DecodingFor optimum decoding of high-resolution audio tracks, the PM7005 features the reference-class CS4398 digital-to-analog converter, which is also found on Marantz reference disc players and amplifiers. The PM7005 can accept a broad range of digital audio sampling frequencies and bit depths, all the way up to 24 bits and 192 kHz sampling. In addition to decoding high-resolution PCM tracks, the PM7005 can also decode DSD high-resolution audio files, at 2.8 and 5.6 MHz. DSD is the advanced digital audio system found on SACD, offering enhanced sonic depth. Equipped with dual master clocks for the digital-to-analog conversion function, the PM7005 also features a fully-enclosed and shielded digital audio block to prevent interference between the analog and digital audio sections.Source Direct Function and Analog Amplifier ModeThe Source Direct function bypasses unnecessary analog circuitry (balance, treble, and bass controls) for the shortest and straightest signal path. The analog amplifier mode shuts down the entire digital audio block, to prevent interference when listening to analog sources.USB-B 2.0 Asynchronous Port with Jitter RemovalThe PM7005 is equipped with a USB-B 2.0 asynchronous port along with dedicated jitter removal processing to provide the high sound quality with high-resolution digital tracks.Advanced HDAM Discrete Buffer Amplifier ModulesThe PM7005 features Marantz HDAM-SA3 (Hyper Dynamic Amplifier Module) components, which consist of matched precision discrete selected circuit elements on a compact sub-board, instead of conventional op-amp integrated circuits. HDAM modules are used in the phono amp/equalizer block, the digital audio block, and in the power amplifier block. These Marantz HDAM-SA3 modules provide a full 10 dB of signal-to-noise improvement over earlier HDAM versions, along with ultra wide-band response (100 kHz, -3 dB) for clear treble detail.Fully Discrete Volume Amplifier CircuitThe volume amplifier circuit features all-discrete circuit components (no op-amps in the signal path) for pure sound quality, low distortion, and wide frequency response.Versatile Remote Control OptionsEquipped with remote control input and output jacks, the PM7005 lets you connect via your Marantz player and/or your Marantz network audio player so you can place the amplifier in a cabinet out of sight and have it remotely controlled along with the disc and network audio players with a single remote control, which helps to reduce component clutter. The remote control includes dedicated buttons for a Marantz disc player and a Marantz network audio player.Additional FeaturesStrong power supply with high current type Schottky diodeMarantz original gold-plated solid brass speaker terminalsDigital optical and coaxial inputs with 192 kHz/24-bit D/A conversionUSB-B input for PCM 192 kHz/24-bit and DSD audio streaming (DSD 2.8 and DSD 5.6)Signal isolator for DAC Mode operationSA2 and SA3 HDAM versionsCurrent feedback topologyCustomized componentsSolid, aluminum extrusion heat sinkLinear drive power supplyAuto power offLow standby power consumption of 0.2W HDAM TechnologyThe 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.High-Current Power SupplyThe 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.Fully Discrete High-Current Output StagesThe 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.Solid Chassis ConstructionFor stability and protection from induced vibrations, the PM8005 features a rugged chassis design, which includes a triple-layer bottom plate.
