A five-input stereo miniature mixer in a tough, compact, aluminium housing. Five channels have XLR electronically-balanced mic/line input, 4-way mic powering, input attenuator, bass-cut switch and rotary fader. All channels (except 3) can be routed to their respective left, right or both centre (ch1 and 2, 4 and 5). Additionally channels 1 and 2 can be ganged for a stereo or M-S microphone (with or without decoding to A-B) and channel 2 has a phase-reversal switch. Channel 3 can be routed left, right or to a pan control. Balanced monitor returns and mix-bus inputs are also provided on multipin I/O connectors A and B respectively.

The output has a master gain fader, PPM or VU meters with battery level indication, switchable twin-mono or stereo limiter with peak indicators, internally adjustable tone-inject with selectable left-channel interrupt. Main outputs are on both XLR and multipin A, each separately-switchable mic/line (Mic and line signals are separately transformer-balanced and floating. Multipin I/O connector A is shared with the monitor return inputs for single-cable connection to recorder etc.). Subsidiary I/O connector B provides unbalanced stereo outputs of –10dBu and allows all five channels to be extracted in pre- or post-fader mode.

Headphone monitoring (A or B-gauge jack, adjustable level) has 6-way rotary selector for stereo, R, L, M-S (decoded), L-R and L+R, and pre-fade listening is selectable for channels 2, 3, 4 and 5 as well as mixer/aux selection. A slate-microphone is built-in, actuated by front-panel switch, and meters have LED illumination. The right channel meter has a suppressed-zero battery voltage scale, selected by a front panel push putton.

Powered by 8 AA size alkaline batteries giving more than 10 hours continuous use, with multi-function four-pole DC input (6–24V), providing battery charging and external powering, and “pass-through” powering with auto-reset fuse to feed an accessory connector (and hence powering radio-mic receivers etc. through mixer on/off switch).
