Description of Marantz PM7005 stereo amplifier

Integrated stereo amplifier Marantz PM7005 combines the latest digital audio technology and classic Hi-Fi solutions company. The device is manufactured in a metal enclosure with thick milled front panel, made in a simple symmetrical design. On the edges are the selector inputs and volume control, and the center knobs are tone control at low and high frequencies and stereoballs. Also there are several buttons for operation of the basic modes, the led indicator of the selected source and 6.3 mm Jack for connecting stereotipov.

Sound of Marantz PM7005 fully implemented on discrete elements (including the use of audiophile-grade components) and the modules HDAM current feedback. PCB both channels are completely symmetrical, which provides a good stereo image and minimal imbalance of their characteristics. The amplifier has an output of 2 x 60 W into 8 Ω, and for cooling of the output transistors used massive aluminum radiators. The power supply Marantz PM7005 built on the basis of a shielded transformer excess capacity, and its equipped with a quick-rectifiers Schottky diodes.

Marantz PM7005 features four line inputs and a built-in Phono stage for MM cartridges with very high settings. An interesting feature of this model that will surely appeal to many music lovers, is a built-in digital-to-analog Converter. Marantz PM7005 has optical and coaxial outputs, and a USB connector for connecting to a PC. Amplifier DAC based on CS4398 chip and is able to receive digital stream with parameters up to 24 bit / 192 kHz (USB input) data DSD (2.8 MHz and 5.6 MHz). DAC output and set the module HDAM-SA3, which provides accurate matching with the amplifying part of the apparatus. In the case of Marantz PM7005 only with analog sources, all digital circuits can be disabled, which provides lack of distortion and crosstalk.
