ASP800 Manual

ASP800 is an eight-channel microphone preamplifier and ADC designed to expand an audio interface or recorder. It combines eight Audient Console microphone preamps, eight line inputs, two discrete JFET instrument inputs, eight balanced analogue outputs and ADAT output in a 1RU unit.

Channels 1 and 2 are RETRO channels. Each adds two variable colour stages: the HMX MOSFET harmonic saturator and the IRON transformer drive stage.
