NOTES
R
ated conditions:
Input signal: 100 Hz sine, nominal input voltage applied
C
rossover (frequency) control fully clockwise.
N
otch filter off.
L
evel adjusted such that the rated output power is obtained
if the limiter is disabled (L
evel in center position
approximately).
Signal voltages stated as RMS values.
0 dBV corresponds to 1 V RMS.
M
in. input voltage: Input voltage required for rated output
power (without limiter) with l
evel fully clockwise
M
ax. input voltage: Input voltage that does not cause more
than 1% THD+N, suitable control settings provided
T
HD + N: Total harmonic distortion + noise, with input and
output levels 10 dB below rated conditions.
E
quivalent 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.
R
esidual noise: Output noise when the level control is set to
minimum.
D
ynamic range: Ratio of nominal output voltage to residual
noise voltage
