MIXER & SOURCE SELEC TORS
The metering is carried out after the compressor/limiter section and consists of two rows
of 12 round LEDs showing levels between -17dB and +11dB. An internal jumper allows the
metering to follow either the stereo output, or the headphone monitor outputs and a rear
panel DIPswitch can disable the peak hold display.
The XLR-3 stereo line output can be fed from either the mic or line input, but not the stereo
monitor input. The line output is electronically balanced and can be wired unbalanced
by grounding the non-phase signal, allowing you to feed both balanced and unbalanced
equipment. A pushbutton switch is provided to reduce the output by 10dB for this purpose.
The headphone output volume control is on the front panel. Each headphone output is
designed to drive 150 mW into 32Ω to 600Ω stereo headphones.
An LED power indicator on the front panel displays the power supply connection.
