The P501 provides a high quality tracking solution in a single width 500 Series compatible module.
The only 'channel strip' solution for the lunchbox® with mic pre/hi pass filter/compressor/limiter and dual bargraph metering.
Flexible choice of mic, instrument and line level inputs feeding the class leader in tracking compressors featuring the multistage peakride system; wonderfully smooth on vocals and great for tightening up bass lines.
