A combination of valve sound and high transistor performance. The SA-31 preamplifier works with highly precise ALPS potentiometers. The amplifier connections for the right and left channels are separate in order to achieve a high noise voltage distance. The output amplifier is designed with Class A technology. Inputs and outputs are optimised.
Frequency response: 20 Hz - 50 kHz +/- 0.5 dB, Output voltage: 2 V
Total harmonic distortion: < 0.1 % (1 kHz, 1 Watt)
Input sensitivity: 150mV, Signal-Noise ratio: > 90 dB
