VU Meter range :-
Standard VU points from -20VU to +3VU where
0VU = +4dBu = 1.228 vac. Front panel trimpot to
align the 0VU point.
Input headroom :-
At least 20dB above the red +3VU LED
i.e. At 0dB input gain = 20dB above +3VU = +7dBu
= > +27dBu clip point.
Or at -20dB input gain = 20dB above +3VU =
+27dBu = > +47dBu clip point.
Outputs :-
Gain :-
Stereo outputs are unity gain
Aux outputs are unity gain
Monitor outputs are unity gain
Headphone output amplifiers have +20dB gain but
the level produced in the headset depends on their
impedance.
Output Impedance :-
< 75 ohms balanced except headphones which are 22
ohms unbalanced.
Frequency response :-
< +/- 0.5dB at 20Hz and 20KHz ref. 0dBu @ 1KHz
Noise :-
< -75dB
Crosstalk :-
< -70dB @ 1KHz
Headroom :-
Maximum outputs all > +26dBu
Distortion :-
< 0.075% @ 1KHz
Power Supply
Current draw :-
< 120 VA per unit (approximately < 1 amp @ 120
volts or < 0.5 amp @ 240 volts 50 or 60Hz)
Warranty :-
One year parts and labor limited warranty.
