Notes:
. Sensitivity
1
Input sensitivities refer to 50 W into 4 ohm, full gain and master settings,
neutral tone control settings, and 1 kHz sine-wave test signal.
2
. Noise and dynamic range
Equivalent input noise voltages are typical values obtained by measuring
noise voltage at speaker output and dividing by the voltage gain of the
amplifier for white noise. Full gain and master settings, neutral tone
control settings, input shorted, measuring bandwidth 20 Hz – 20 kHz.
Dynamic range of power amplifier: Ratio of between output signal at
limiter threshold to A-weighted output noise with m
position.
. Output levels
3
Output levels refer to 50 mV / 1 kHz sine-wave test signal at channel 1
input, full gain and master settings, neutral tone control settings, send
fully clockwise.
4
. Options
Gain of channel 2 in mic mode can be decreased by 4.6 dB by an internal
jumper.
48 V phantom power can be deactivated by an internal jumper.
9 V phantom power for channel 1 can be applied by an internal jumper
to the “ring” terminal of the input jack. C
care. Read the operating instructions.
