Approximate actual power available at "clipping" 110 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) 15Hz to 80kHz.

FREQUENCY RESPONSE: (-3dB points at 1 watt) 1Hz to 100 kHz.

INPUT SENSITIVITY: 1.9V RMS (Bal or SE) for rated output. (23.5 dB gain into 8 ohms.)

  INPUT IMPEDANCE: 200K ohms Balanced, 100K ohms Single-ended.

OUTPUT TAPS: 8 ohms, 4 ohms.

OUTPUT REGULATION: Approximately 0.8dB 8 ohm load to open circuit (Damping factor approximately 11).

OVERALL NEGATIVE FEEDBACK: 10dB.
