POWER OUTPUT
75 watts per channel continuous from 20Hz to 20kHz. 1 kHz total harmonic distortion typically 1.5% at 75 watts, .05% at 1 watt. Approximate actual power available at “clipping” 80 watts (1kHz). (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
POWER BANDWIDTH (-3dB points)
12Hz to 70kHz.
FREQUENCY RESPONSE (-3dB points at 1 watt)
1.0Hz to 70 kHz.
INPUT SENSITIVITY
0.55V RMS Single-ended for rated output. (32.5dB gain into 8 ohms.)
INPUT IMPEDANCE
52.5K ohms Single-ended.
INPUTS
SE1, SE2, SE3, Phono, S/PDIF digital (coax RCA and Toslink), USB
MAXIMUM INPUT
10V RMS (any input).
OUTPUT POLARITY
Non-Inverting (any input).
OUTPUT TAPS
8 ohms, 4 ohms.
OUTPUT REGULATION
Approximately 2dB 8 ohm load to open circuit (Damping factor approximately 4).
OVERALL NEGATIVE FEEDBACK
4dB.
