The Technics SU-A6 is a high performance preamp which can be used with any high fidelity power amplifier.
It employs class A circuitry from input to output, and FET differential inputs in all stages for complete input capacitor-less (ICL) circuitry.
Basic circuitry consists of the high gain ICL phono equalizer amp, ICL DC flat amp, and DC output amp.
Only one coupling capacitor is used (at the phono equalizer output), making this amp capable of straight DC amplification from high level inputs (tuner, aux, and tape) to
Frequency response: 1Hz to 20kHz
Total harmonic distortion: 0.002%
Input sensitivity: 0.25mV (MC), 2.5mV (MM), 150mV (line)
Signal to noise ratio: 74dB (MC), 88dB (MM), 106dB (line)
Channel separation: 56dB (line)
Output: 150mV (line), 2V (Pre out)
Dimensions: 430 x 97 x 360mm
