The RMX 80 Digital is a fully digital 4+1 channel performance mixer. Each channel has a bipolar filter and a switchable EQ that can act as a classic EQ or as a kill isolator. Fader and crossfader curves are adjustable, both faders support fader start, and the crossfader slot is compatible with Innofader replacements. Two independent beat counters detect tempo automatically.

The effects section offers 13 effects, including flanger, delay, echo, reverb, pitch shift, loop roll, bitcrusher and tape delay, plus send/return use. Time bar buttons give direct access to modulation such as trigger, LFO, time and pitch, and an LC display shows the active settings. Two mic channels have a 2-band EQ and talkover with active ducking. Headphone monitoring offers solo cue and mix cue modes, with a one-knob headphone EQ and a mono/stereo switch.

On the back there are inputs for up to nine sources, balanced XLR and unbalanced RCA master outputs, record, booth and send outputs, and a 3-way USB hub for an extra audio interface or controller. A setup menu covers zone routing, limiter, talkover threshold, crossover frequencies and firmware updates.
