Notes:

. Input sensitivities refer to 160 watts into 8 ohms at full gain and

1
volume settings, neutral tone control settings (i
anticlockwise), and 1 kHz sine-wave test signal.

2

. Output levels refer to –25dBV (56.2 mV) / 1 kHz at instrument
input, unless stated otherwise.
Earlier models have a D

. Bandwidth of tone controls refers to one-half of gain at center

3
frequency, in decibels. For example, if a tone control has 15 dB
center gain, then bandwidth refers to the 7.5 dB points.

4

. Equivalent input noise voltage obtained by measuring noise
voltage at speaker output and dividing by the voltage gain of the
amplifier for white noise. Full gain and volume settings, neutral
tone control settings, input shorted, frequency range 20 Hz – 20
kHz.

Dynamic range of power amplifier is defined as ratio of output
voltage at limiter threshold to A-weighted noise voltage at m
volume in zero position.

. Compressor threshold refers to 1 dB gain reduction and input gain

5
fully clockwise, ratio refers to 20 dB gain reduction. Ratio varies with
gain reduction due to soft-knee compression.

6

. If required, aux in and return signals can be disconnected from DI

ut by an internal jumper even in the post switch position.

o

ine out can be made master-independent by an internal jumper.
