AD-2850 is the dedicated phono equalizer unit. Analog records can be reproduced with high quality by installing AD-2850 in a rear-panel slot. The AD-2850 features separate input circuitry for MC and MM cartridges to ensure optimum matching and realize outstanding S/N ratio. 2 sets of analog-player input jacks, the AD1 and AD2 are equipped, and their selections are switchable with the INPUT selector of pre-amplifiers.
The AD-2850 uses printed circuit boards made from glass cloth fluorocarbon resin, housed in a sturdy aluminium enclosure to minimise any kind of external influence. The input terminals are connected to the amplification circuitry by the shortest possible route, realising outstanding signal/noise ratio. The use of a DIN standard connector for the link to the host component provides enhanced reliability.
