NOTES
Rated conditions:
Input signal: 100 Hz sine, nominal input voltage applied
Crossover (frequency) control fully clockwise.
Notch filter off.
Level adjusted such that the rated output power is obtained
if the limiter is disabled (Level in center position
approximately).
Signal voltages stated as RMS values.
0 dBV corresponds to 1 V RMS.
Min. input voltage: Input voltage required for rated output
power (without limiter) with level fully clockwise
Max. input voltage: Input voltage that does not cause more
than 1% THD+N, suitable control settings provided
THD + N: Total harmonic distortion + noise, with input and
output levels 10 dB below rated conditions.
Equivalent input noise voltage: Noise voltage at speaker
output divided by gain of amplifier at 100 Hz. Control
settings as stated under rated conditions. Measurement
range: 20 Hz – 20 kHz. Input shorted.
Residual noise: Output noise when the level control is set to
minimum.
Dynamic range: Ratio of nominal output voltage to residual
noise voltage
Specifications and appearance subject to change without
notice.
