Input Stage
Three audio input types are provided for, these are:
Balanced microphone input, for use with either dynamic or
phantom powered condenser microphones. Connect via the XLR
input connector for the corresponding channel on the rear of the rack
frame. Select switch number (7) to ‘line’.
Balanced line level input, for use with any line level source, most
commonly when using the P501 as an insert effect within the
recording or mixdown chain. Connect via the ¼” jack (9) on the front
of the P501 module. Switch number (7) selected to ‘line’.
Unbalanced instrument input, for direct injection of most electric or
bass guitars. This is sometimes called the DI-INPUT (direct
injection). Connect via the ¼” jack (9) on the front of the P501
module. Switch number (7) selected to ‘instr’.
All three input types have different gain ranges available within the
P501 to suit the type of source, all controlled from a single gain
control (2).
+48V Phantom power is selected on by selecting switch (1)
downwards. Always connect the microphone before switching on
phantom power and always switch off phantom power before
disconnecting the microphone. Always best to mute your monitoring
chain first as switching phantom power cause audible ‘thumps’
through your audio chain.
High Pass Filter
The high pass filter is sited in the audio signal path immediately after
the input stage but before the compressor and limiter. It operates at
80Hz with a slope of 18dB/octave.
Bring the high pass filter into circuit by selecting switch (3)
downwards.
