P1 Audio Processor User Manual Page 7
 The unbalanced INSTRUMENT input (2 pole ¼” jack plug)
has priority over the MICROPHONE input.
 The balanced MICROPHONE input (3 pole XLR plug) has
the lowest priority.
The connector wiring follows normal audio convention. Details are
given later in this manual.
Although the three inputs share a common input gain control, the
gain range available to each input is different and appropriate to that
input;
MICROPHONE GAIN 0dB to +70dB
INSTRUMENT GAIN 0dB to +30dB
LINE INPUT GAIN -10dB to +20dB
PHANTOM POWER
The microphone input has switchable +48V phantom power suitable
for powering most types of studio condenser microphones.
ALWAYS CONNECT THE MICROPHONE FIRST
BEFORE SWITCHING ON THE +48V otherwise
damage to the microphone amplifier is a possibility.
In a similar way, always switch off the +48V and wait
for 10 seconds before disconnecting the microphone.
If you are unsure whether a microphone requires
+48V phantom powering always check with the
microphone manufacturer first. DON’T GUESS!
Most professional BALANCED dynamic microphones will not be
damaged through the accidental application of phantom power.
