How to choose
Match the unit to the stage of your signal chain, tracking, preamp or mix bus.
Beginner
Someone new to analog processing should start by learning the 3124V preamp on a single vocal or instrument source, listening for how gain and tone change before adding compression or EQ. Keep gain staging conservative until the sound of the preamp becomes familiar.
Intermediate
A home studio owner mixing full songs can bring in the 5500 equaliser to shape individual tracks, then use the 2500+ compressor across the stereo bus to glue the mix together. Make small adjustments and compare against a reference track often.
Expert
A working engineer will use the 3124V, 5500 and 2500+ together across a full session, tracking through the preamp, shaping tone with the equaliser and controlling dynamics on the bus. Document settings that work well for repeat sessions and keep the units serviced for consistent tone.
