GENERAL
All Outputs:
Normal Operating Level = +4dBv
Maximum Output Level = +2ldBv 20Hz to 20kHz
Output Impedance = 30ohms
all outputs are protected against damage from accidental short
circuits.
Maximum Gain From Channel Input to Stereo Output: = +70dB
Frequency Response:
Channel Input to Stereo Output = 30Hz to 30kHz +/-1dB
Equaliser Characteristics:
HF = 15dB continuously variable at 10kHz
MID = +/-13dB continuously variable at any frequency between 400Hz
and
6kHz.
Q factor = 1.4
LF = +/-15dB continuously variable at 100Hz
Total Harmonic Distortion:
Channel Input to Stereo Output typically 0.05% THD
Noise:
20Hz to 20kHz MEASURED AT STEREO OUTPUT.
Figures quoted are
RMS
noise referred to system operating level.
Microphone Equivalent Input Noise = -125.5dBv
Output with Master Faders Closed = -94dB ref 0VU
Output with Master Faders Raised,
All Inputs Closed better than
-66dB ref 0VU
