Gain
Mic. input to stereo outputs, channel and master fader
at 0dB, panned full A or full B:............................................... 10 - 50 dB +/-20 dB i.e. -10 to +70 dB
Line input to stereo outputs, channel and master fader
at 0dB, channel panned full A or full B:.................................. +/-20 dB (corresponds to -14 dBu to
+26 dBu input level for +6 dBu output)
Frequency response
Line input or mic. input at 10 dB gain, to stereo or AUX outputs,
30 Hz: 0 +0/-0.5 dB
100 Hz-20 kHz:............................... . 0 +/-0.2 dB
Mic. input at 50dB gain, 30 Hz:.............................................. 0 +0/-0.7 dB
100 Hz-20 kHz................................ 0 +/-0.2 dB
Distortion
(T.H.D.+ NOISE)
OUTPUT LEVEL
+6 dBu: +20 dBu:
Mic. input, 10 dB gain, 30 Hz.............................................. <0.2 % <0.6 %
1 kHz.............................................. <0.05 % <0.05 %
20 kHz............................................ <0.05 % <0.05 %
Mic. input, 50 dB gain, 30 Hz.............................................. <0.3 % <0.6 %
1 kHz.............................................. <0.2 % <0.3 %
20 kHz............................................ <0.2 % <0.3 %
Line input, 0 dB gain, 30 Hz.............................................. <0.2 % <0.5 %
1 kHz.............................................. <0.02 % <0.02 %
20 kHz............................................ <0.02 % <0.05 %
Output noise level
All channels routed to a main ouput, channel faders at minimum
gain, output fader at 0 dB gain (N10 system noise):.............. -77 dBu, CCIR weighted peak
-85 dBu, RMS 22 Hz-22 kHz
As above, one channel fader open, line input:....................... -74 dBu, CCIR weighted peak
-83 dBu, RMS 22 Hz-22 kHz
Mic. input, 50 dB gain:........................................................... -64,5 dBu, CCIR weighted peak
-74,5 dBu, RMS 22 Hz-22 kHz
Crosstalk attenuation:
(20 kHz:)
Line input to mic. input, mic. gain 10 dB:............................... >95 dB (105 dB ref. to input)
Line input to mic. input, mic. gain 50 dB:............................... >68 dB (118 dB ref. to input)
Across closed channel fader:................................................. >90 dB
Across channel AUX pot:....................................................... >90 dB
Across channel AUX switch (AUX1-2):.................................. >95 dB
Across channel A/B ON switch in off position:....................... >90 dB
Across panpot:....................................................................... >68 dB
