CHIAMARE PER QUOTAZIONE

 

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 

(5) 1, 2, 3, 4, 5 (Single Ended RCA connectors).

OUTPUT REGULATION 

Approximately 2dB 8 ohm load to open circuit (Damping factor approximately 4).

OUTPUT TAPS

8 ohms, 4 ohms.

OVERALL NEGATIVE FEEDBACK 

4dB.

SLEW RATE

10 volts/microsecond.

RISE TIME

4 microseconds.

HUM & NOISE

Less than 1.0 mV RMS -88dB below rated output (IHF weighted, Vol down).
