House Engineer or Hired Mixer: Choosing Who Runs Your Live Sound

Sooner or later every producer planning a live event or a recorded broadcast has to decide who sits behind the mixing desk. There are two realistic options. You can use the engineer who comes with the venue, often called the house engineer, or you can bring in a mixer of your own choosing who works to your brief. Both can produce a good night. Both can also go wrong, and usually for reasons that were visible a fortnight before the doors opened.

I write this as someone who has watched both arrangements from the production desk for a long time, and the short version is that neither is better in every case. What matters is how much of the show is already known, how many acts or speakers you have, and whether the sound is also being recorded or streamed. The sections below compare the two on the points that decide it, and I finish with what I would choose and why.

A note on scope: I am looking at front-of-house and monitor mixing together, because on small and mid-sized shows the same person often handles both, and the choice of engineer shapes how the stage sounds to performers as much as how the room sounds to the audience.

A house engineer knows the room. They know where it rings, which corner swallows low frequencies, how loud the room can run before the neighbours or the licensing conditions become a problem, and which of the venue's microphones and cables can be trusted. That knowledge is difficult to replace, and on a tight load-in it saves real time. They also know the venue's desk, its routing and its quirks, so there is no hunting for a hidden mute group ten minutes before the first act.

Cost is the other strength. The engineer is usually included in the venue hire or charged as a modest add-on, which keeps the budget simple, and for a straightforward evening with a few acts or a talk with a panel that arrangement is often entirely sensible.

The weakness is that the engineer meets your show late. They are serving many clients, they may see your stage plot for the first time on the day, and they have no stake in how the recording or stream sounds afterwards. Good house engineers work around this with great skill, but they can only work with what they are given.

• Knows the room, the desk and the venue's own limits
• Usually included in hire, so budgeting is simple
• Meets your show late and may not have heard the material

A mixer you appoint yourself starts from your show rather than from the venue. They read the run sheet, ask about the microphones the performers prefer, plan channel lists and sit down with the artists or speakers before the doors open. For a programme with changing line-ups, a live band with in-ear monitors, or a corporate event with presenters who have never held a microphone, that preparation shows up directly in the result.

They are also the better choice when the audio leaves the room. If the event is being recorded, streamed or fed to a broadcast truck, someone has to think about the feed as well as the room, and a mixer who owns the whole chain can make a separate decision for each. I would add that a hired mixer is accountable to you alone, which makes the conversation after the event more useful.

The cost is higher, since you pay a fee and sometimes travel, and the mixer still needs time in the room to learn it. They may also need to bring or hire a desk if the venue's is unsuitable, which adds a line to the budget that deserves checking early.

• Plans from your run sheet and your performers' needs
• Can look after recording, streaming or broadcast feeds as well as the room
• Costs more and still needs time to learn the venue

Set side by side, the difference is less about skill than about information and time. A house engineer has deep knowledge of the place and shallow knowledge of the show. A hired mixer has deep knowledge of the show and shallow knowledge of the place. Each gap can be narrowed. The house engineer can be briefed properly, and the hired mixer can be given a site visit or at least photographs and a floor plan, along with the venue's technical specification.

The sound check shows the gap clearly. With a house engineer, a check on a crowded day is often a quick line check followed by a few songs. With a hired mixer you can ask for a longer, structured check because the engineer is working for you, and you can agree beforehand which acts or speakers must be heard on stage before anything else.

Risk is the third point. A house engineer is a single point of failure if they are ill or double-booked, but the venue is obliged to supply a replacement. A hired mixer is a single point of failure too, and the replacement is yours to arrange, so ask what the plan is if they cannot attend.

• House engineer: strong on the room, weaker on the show
• Hired mixer: strong on the show, weaker on the room
• Check who covers if either person is unavailable

For a simple evening with a handful of acts or speakers, no recording and a venue with a decent in-house system, I would use the house engineer and spend the saving on a proper briefing. Send the stage plot, the channel list and the running order at least a week ahead, and ask for a short call. That small effort closes most of the gap.

For anything with a live feed, a recording, a changing line-up, in-ear monitors or a large audience, I would hire a mixer and treat the house engineer as a colleague rather than a rival. The two can work well together, with the venue's person handling the system and your mixer handling the show. In practice it is the arrangement I choose most often on the productions I plan.

Autumn is a good time to settle this, because the busy run of seasonal events fills diaries quickly and the better mixers are booked weeks ahead. Decide who is mixing before you fix the date if you can, and confirm the arrangement in writing.

Whichever way you lean, a short list of questions makes the decision firmer. Ask the venue for the technical specification of its system and the name of the engineer who would work your event. Ask whether the engineer has mixed this kind of programme before, whether they can be at the sound check from the start, and what the limits on volume are. If you hire your own mixer, ask how they plan to learn the room and what they need from you.

Then write down who is responsible for what. It sounds obvious, but many problems on the night come from two capable people each assuming the other had the monitors, the radio microphones or the recording feed. A one-page note listing who does what, and who has the final say if something changes, belongs in the run sheet.

Finally, agree what a good result looks like before the day. Clear speech at the back of the room, a stable feed to the stream, or comfortable monitors for the band are all reasonable goals, but they are different goals, and the person at the desk should know which one comes first.

• Request the venue's technical specification and engineer's name
• Confirm attendance at the sound check from the start
• Record who handles monitors, radio mics and recording feeds
• Agree what a good result means for this event
