LEFT SIDE PANEL
Balanced channel inputs
– four electronically balanced circuits (transformer balanced is optional) in
phase with one another. XLR connectors should be wired as pin1 ground, pin2 +phase signal and pin3 –
phase signal.
Microphone powering selector switches
– The input sensitivity in position D is DYN 200 = 0.2 mV and
no power. Selected 48, 12, T, mic powering, 10 dB of attenuation is automatically introduced, considering the
sensitivity of condenser mics.
Phase reverse switches
– Intended to compensate for a phase error due to wiring or mic placement.
Phantom on / off switch
– The current consumption of the phantom power supply is 13 mA. Phantom
power supply may be switched off (only if using dynamic, wireless of T powering mics) to increase the
lifelength of the internal batteries between two chargings.
Attenuation switches
– The gain of the mic preamplifiers may be decreased by –10 dB in position D. In
positions 48, 12 and T the attenuation is –13 dB.
Mic / line level switches
– Selects mic or line to add –60 dB attenuation before the mic preamplifiers.
Optional NP1 Battery Holder
– The switched mixer supply is derived either from the internal AA batteries
or from NP1 battery depending on the position of the panel side switch.
