The pre-out has been changed to 4ch, further improving the expandability of the system!

5ch power amplifier with built-in 9chDSP
Digital input terminal: 96KHz/24bit format compatible
M-5.4DSP is based on the popular M-5DSP MK2 and has a 4ch pre-out to improve system development.
A new generation processor amplifier that achieves high power and ultra-low power consumption despite its ultra-compact size.
High level input is 4 channels, input signals can be mixed and level adjusted up to 4 systems, and it is possible to synthesize the output of a genuine multi-system into a signal close to the full range.
Equipped with Audiotech Fisher's unique VCP (Virtual Channel Processing) function as standard, improving usability of the FX (sound effect) function when synthesizing input signals.
