Monitor mix

The engineer sends selected input channels to an auxiliary bus and routes that bus to the appropriate monitor output. Each source has its own send level, allowing a vocalist to receive more voice while a drummer receives stronger rhythmic references. Separate buses provide independent mixes when performers need different balances, subject to the console and output capacity.

Many monitor sends are configured pre-fader so audience mix moves do not change the stage balance. That does not necessarily make them independent of input gain, equalization or all channel processing. The chosen tap point determines what is shared. Understanding the aux send arrangement is essential before promising that a monitor mix will remain unaffected by other adjustments.

Performers use monitoring to judge pitch, rhythm, articulation and ensemble relationships. A useful mix reduces uncertainty without filling every available space with sound. The most important reference may be a lead vocal, a rhythmic instrument, a musical cue or simply enough of the performer's own source to avoid pushing harder than necessary.

Louder is not automatically clearer. Extra channels can mask the reference the musician actually needs, and excessive wedge level can spill into microphones or the audience area. A focused monitor mix supports the performance while preserving room for the FOH mix. Listening needs are individual, so asking a precise question usually works better than assuming everyone wants the full band.

A wedge is an acoustic loudspeaker near live microphones, so position matters. Aim it towards the performer while considering the microphone's pickup pattern and rejection directions. The best location depends on that pattern and the stage geometry, not a rule that every wedge belongs directly behind every microphone. Changes in performer position can change the available feedback margin.

• Mono mixes use fewer output paths and can provide a direct, simple reference.
• Stereo in-ear mixes allow spatial separation when the system supports it, but require an appropriate stereo routing plan.
• Shared mixes save resources but require agreement about priorities; independent mixes are useful when needs conflict.

During soundcheck for a band in Abu Dhabi, the lead singer asks for everything louder in the wedge. The engineer asks which element is hardest to follow and learns that the singer cannot distinguish the vocal from a nearby guitar amplifier. Reducing unnecessary guitar in that monitor and discussing amplifier direction improves the reference without a large increase in wedge output.

The keyboard player needs a different balance with a clear rhythm reference, so a separate bus is used. Each output is labelled and checked from the intended listening position. A stable soundcheck process gives the band time to request changes with full musical context, rather than making every decision while one isolated input is being tested.

1. Ask each performer for essential sources and identify whether the destination is a wedge or an in-ear system. Confirm mono or stereo requirements before allocating outputs.
2. Start with controlled output levels and verify that each bus reaches the correct destination. A mislabeled wedge can make sensible adjustments appear ineffective.
3. Introduce the primary reference, then add other sources only as needed. Test with realistic playing rather than relying exclusively on spoken microphone checks.
4. Check the mix with the whole ensemble. Masking and stage spill often reveal problems that were absent during individual source checks.
5. Agree on simple change requests and communication signals. Keep attention on the performer while making a change and confirm whether it solved the actual problem.

For artists learning to describe these needs, BarCoe Studios runs short hands-on live sound certificate courses for artists. Its sound better on stage course is a relevant starting point for understanding performer communication without needing to operate every console function.

• Adding the entire band to every wedge by default. Begin with musical priorities and let direct stage sound provide what is already sufficiently audible.
• Chasing a feedback problem with more output level. Find the affected route and consider placement, microphone behavior and appropriate equalization.
• Changing shared preamp gain without checking existing monitor balances. A change made for the audience mix can alter multiple performer feeds.
• Making large unannounced changes during a song. Small, confirmed adjustments reduce surprises, particularly for isolated in-ear listeners.

A further mistake is ignoring the difference between a missing source and a source that is present but masked. Solo listening can confirm the source exists, but the performer hears the combined stage environment. Ask for a short passage that demonstrates the difficulty, then adjust the competing content or source position where possible. Monitor work is a conversation supported by routing, not simply a race to increase send levels.
