Accuphase AD-2900 Phono Equalizer Module for C-2900

Accuphase AD-2900 Phono Equalizer Module for C-2900 AD-2900 is the dedicated phono equalizer unit. Analog records can be reproduced with high quality by installing AD-2900 in a rear-panel slot. The AD-2900 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. Contains equalizer units with boards using glass cloth fluorocarbon resin with totally separated left / right channels Ideal MC/MM independent input circuit to achieve high noise performance Differential-style equalizer for high-precision RIAA characteristics Two input terminals to connect up to two tone arms Functions that can be operated from the front panel Memory settings for each input terminal Robust aluminum case to shield against external noise MC Gain : 64 / 70 dB switching Input impedance : 10 / 30 / 100 / 200 / 300 ohms switching MM Gain : 34 / 40 dB switching Input impedance : 47 kilohms rated Differential amplifier circuit with ultra low noise bipolar-transistors for MC cartridges.
