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.
