Accuphase AD-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.
