Marantz SC-7S2

The Marantz SC-7S2 is a reference control amplifier that is a part of Marantz's reference series of A/V devices which gives the improves upon the design of the acclaimed SC-7S1. The SC-7S2 gives a frequency response and channel separation that far exceeds conventional requirements thanks to a fully balanced current-feedback topology and a power supply based on a aluminum-encased toroid power transformer, Shottky barrier rectifier diodes, and low-ESR electrolytic storage capacitors for optimal power conditioning and distribution.

Each input is fully buffered with discrete circuitry for accurate signal transfer while four Wolfson WM8816 high-precision multi-gang volume controls and 12 Marantz-proprietary HDAM-SA modules form an incredibly precise attenuation circuit fully capable of 0.5 dB resolution throughout its entire 100 dB range. Although there are only two channel ouputs, the F.C.B.S (Floating Control Bus System) allows for easy expansion and operation of mutli-channel material. The copper-plated aluminum chassis and steel sub-members give dimensional stability and isolation from radio frequencies and  electromagnetic interferences, and the display can be shut off for minimum distractions. There are switchable inputs for CD, two line and a recorder input as well as a balanced XLR input and there is  a rec out, two line outs and a balanced XLR out.
