The mixing console
Open Mixer in the console's menu. The desk has four microphone channels on the left and the master section on the right.
| Control | What it does |
|---|---|
| Input | The microphone for this channel: a sound card input, a connected phone, System Default, or Off |
| GAIN | How loud the microphone comes in. Set it so normal singing lights the green signal LED but loud singing does not light the red PEAK LED |
| HIGH, MID, LOW | Three-band EQ, ±12 dB. A little HIGH adds clarity; less LOW reduces boom close to the microphone |
| COMP | Compressor: brings quiet words up and holds loud ones back. 20–40 % suits most singers |
| ECHO | The classic karaoke echo |
| FX | Reverb, the sound of a room or hall |
| PAN | Left or right in the stereo picture |
| Fader | The channel's level in the mix |
| MUTE | Silences the channel |
Every channel also has a low cut and a noise gate built in, so an open microphone stays silent until someone sings into it.

Display: the output device, whether the mixer is running, where vocal separation runs,
and the feedback guard.
XRUN nmeans the computer was too busy to deliver sound in time n times;BAD nmeans a microphone sent data that was not sound n times (it is replaced by silence). - MAIN OUT: where all sound goes, music and microphones. Prefer a wired device.
- MIC ON: mixes the microphones into the output. RESCAN looks for newly connected devices.
- Feedback guard: see below.
- Effect preset: Pop, Ballad, Rock, KTV Hall and Dry set the EQ, echo and reverb of every channel at once. Save As keeps your own setting (taken from channel 1).
- MUSIC, MICS, MAIN: the music level, all microphones together, and everything.
The phone page's REMOTE tab has the same microphone controls, so singers can adjust their own sound.
Feedback is the squeal when a microphone picks up its own sound from the speakers. The guard listens for a single pure tone that stands out and cuts just that frequency.
| Setting | Behaviour |
|---|---|
| Off | Nothing is cut |
| Low (default) | Only a tone that keeps getting louder, as feedback does, or that lasts a full second. Whistling and held notes are left alone |
| Medium | Any steady pure tone after about a tenth of a second. A whistle is cut too |
| High | Quicker and less picky still |
The display shows how many frequencies it is cutting. Cuts are released by themselves after a while.
- Start with the Pop preset and every fader at the 0 mark.
- Set GAIN while someone sings their loudest part: no red PEAK.
- Balance MUSIC and MICS so the voice sits on top of the music.
- Add ECHO and FX to taste. Less is usually better for fast songs.
- If it squeals, move the microphone away from the speakers before turning up the guard.
