Although it is so compact, it does its job well.

The newly developed M-5.4DSP is based on the popular M-5DSP MK2 and has a 4-channel pre-out, improving the expandability of the system.
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,
It is possible to synthesize the output of the genuine multi-system into a signal close to the full range.
