Getting Your Live Sound Ready for the Darker Months

Why autumn changes the sound of a room

Mid autumn is when many venue teams return to a full programme of filmed panel nights, local news specials and evening concerts. The rooms have often been quiet since the summer, and they do not sound the way you remember. Cold air and damp walls alter how a hall rings, and an empty space behaves differently from a full one.

I am a lighting designer by trade, but I spend a great deal of time in galleries beside our audio engineer, Joanne Davies, and I have learned to listen for these shifts. A room that felt bright in July can turn boomy once the heating comes on and the doors stay shut. It is worth walking the space before anyone plugs in a microphone.

Treat the first rehearsal of the season as a fresh survey, not a repeat of last spring. Note where the sound seems to gather and where it thins out.

Microphone placement for speech in cooler, draughtier spaces

Clear speech is the first thing audiences notice and the first thing they forgive least. In a news desk or panel setting, a lavalier clipped to a heavy winter jacket or knitwear will rub and thump in ways it never did in a summer shirt. Ask presenters what they will wear, and fix microphones high on the chest, away from scarves and collars.

For desk microphones, keep them off hard table surfaces where possible, or place a thin mat beneath the stand to reduce knocks and reflections. Draughts from doors and heaters can produce low rumbles, so a windshield is worth having even indoors.

Distance matters more than people expect. A speaker who leans in and pulls back will swing the level, and no amount of mixing hides that entirely. A short word with the presenter before going live helps.

• Check clothing before choosing where to clip a lavalier
• Use windshields near doors and heating vents
• Keep desk microphones off bare, reflective tabletops
• Brief presenters on staying a steady distance from the capsule

Mixing for balance when music and talk share the stage

Autumn programming often mixes spoken segments with live music: a host introducing a local band, a panel followed by a short set. The challenge is that these two sources want different treatment, and the transition between them is where a mix tends to fall apart.

Joanne builds her mixes in layers. Speech comes first, set so every word is clear at a modest level, and music is then brought up around it instead of the other way round. Rehearse the handover from voice to band at least once, with the real microphones live, because feedback tends to appear exactly when a host and a singer are both open on stage.

Keep a little headroom in reserve. Applause in a full hall can be far louder than anything you heard in rehearsal, and a mix that was comfortable at soundcheck can clip when the audience arrives.

Monitoring: what the team hears matters as much as the feed

A mix is only as good as the monitoring behind it. In a gallery with poor acoustics, or with a fan humming nearby, it is easy to push levels in the wrong direction. Closed-back headphones help the engineer judge the broadcast feed without the room interfering, but they should be checked against speakers now and then.

On stage, performers and presenters need to hear themselves without spill reaching the audience microphones. Cold weather often means thicker clothing and more people crowding into the wings, so there may be less room for wedges than usual. Plan where each monitor sits and which way it faces.

Agree a simple way for the audio engineer to talk to the director and to the stage manager. A clear talkback line prevents a small problem becoming a visible one.

• Compare headphone and speaker monitoring before going live
• Aim stage monitors away from open microphones
• Set up talkback between gallery and stage

Cables, connectors and the small things that fail in damp weather

Moisture is quietly hard on audio equipment. Connectors that sat in a cupboard over the summer may have oxidised, and a crackle you blame on a microphone can turn out to be a tired XLR. Test every line, and keep spare cables and adapters close to the desk instead of in a van across town.

Radio microphones deserve particular attention. Batteries drain faster in cold rooms, and venues that have added equipment over the year may have more radio traffic than before. Scan for clear frequencies on the day rather than relying on settings from the last event.

Cover stage boxes and floor connections where a spill or a wet coat could reach them, and tape down runs that people will cross in the dark. Good housekeeping rarely gets noticed, which is the point.

A sensible rehearsal routine for the coming months

Evenings are shorter, schedules get busier toward the end of the year, and there is rarely time to fix sound problems in the middle of a show. A simple routine saves a great deal of stress. Arrive early enough to hear the room empty, run the full signal chain, and then rehearse with people in position.

If possible, record the rehearsal and play it back on a different system, such as a laptop or a pair of ordinary headphones. This often reveals harshness or muddiness that the control room hid.

Finally, write down what worked. A short note on microphone positions, gain settings and problem spots turns this season's effort into a head start for the next production.

• Listen to the empty room before setting anything up
• Run the full chain with real people in position
• Record the rehearsal and check it on a second system
• Keep notes for the next event in the same venue

Good live sound in the darker months comes from paying attention to small, unglamorous details: how a room has changed, what people are wearing, how connectors have fared, and how well the team can hear one another. None of it needs expensive equipment, only time set aside to listen and rehearse properly. If your venue is planning a run of filmed events this season, a short conversation early on is far cheaper than a problem discovered during the broadcast.
