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.
