Why autumn is the time to look at your audio
Between now and the new year, most studios and event teams see their busiest stretch: corporate evenings, seasonal broadcasts, indoor concerts and a steady run of recordings. Audio is where small neglected problems turn into audible ones, because a crackling lead or a drifting monitor mix tends to surface exactly when the schedule leaves no room to fix it.
I write mostly about lighting, but I sit next to Daniel Whitcombe's desk often enough to know how his season goes. He treats these weeks as a window for preparation, before the diary fills. The same logic applies to anyone running a room, whether it is a television studio or a hired hall.
This article is the seasonal part of our look at sound engineering. It covers the checks that suit the coming months: what the weather does to equipment, what longer evenings change about live work, and how to plan monitoring and microphones so winter bookings run calmly.
None of it needs new equipment. Most of it needs an hour set aside, a notebook and someone willing to listen critically to the room.
Damp, cold and what they do to microphones
Autumn air carries moisture, and venues that sat empty over summer can be damp when you return. Condenser microphones are the most sensitive to this. Humidity inside the capsule can show up as crackle, a thin sound or a sudden rise in noise, particularly when a microphone moves from a cold van into a warm room.
Allow equipment to reach room temperature before powering it. Keep microphones in cases with a little desiccant, and avoid leaving them in vehicles overnight. If a capsule has clearly suffered, a technician should look at it rather than you drying it with a heat source, which can warp delicate parts.
Cables suffer too. Connectors that look clean can have tarnished contacts after a damp spell. Plugging and unplugging each lead a few times often clears light oxidation, and a continuity test will catch the ones that need replacing.
Wireless systems deserve a separate mention: batteries lose capacity in the cold, so carry spares and swap them on a routine rather than waiting for a dropout.
- Let microphones warm up before use
- Store capsules with desiccant in closed cases
- Test every lead for continuity and noise
- Carry spare batteries for wireless packs
Checking the monitoring chain from the listening seat
Monitoring is the part people trust without testing. Before the busy weeks, sit in the position where decisions are made and play material you know well, preferably something with clear low end, voices and fine detail. Note anything that seems recessed, harsh or uneven between left and right.
Rooms change over time. A new sofa, a rack moved against a wall or a curtain taken down can alter the bass response noticeably. If the studio feels different from last spring, it probably sounds different, and small repositioning of speakers is cheaper than later remixes.
For live work, check each stage wedge or in-ear feed individually. Ring out the wedges at a sensible level, listening for the frequencies that start to sing first, and note them. Repeating this with the same method each season gives you a record you can compare against.
If heating has been switched on again, listen for fan or ventilation noise through the monitors with the room quiet. A faint hum that was absent in August will appear on a quiet voice recording.
Mixing desks: a quiet-period service routine
A mixing desk gets handled constantly and cleaned rarely. Faders collect dust, rotary controls turn scratchy and some channels develop a slight crackle when moved. Autumn is a sensible time to work through each channel strip with the desk powered down, using a suitable contact cleaner applied sparingly and according to the manufacturer's guidance.
Then power the desk up and test every channel with a signal, not just the ones you habitually use. Spare inputs matter on the day a guest arrives with an unexpected instrument. Check the auxiliary sends, the groups and the headphone outputs, since each tends to fail only when someone needs it.
Save and label your scenes. Many digital desks hold memory of a half-remembered setup from months ago, and entering a long production week with a clean, named set of starting points saves a great deal of fumbling.
Finally, note the firmware version and decide deliberately whether to update. Changing it in the middle of a booked run is a risk worth avoiding.
- Clean and test every channel, including spares
- Check auxiliary sends, groups and headphone outs
- Name and back up scenes before the busy weeks
- Update firmware only between bookings
Planning for the longer evenings of live events
Dark evenings bring more indoor events, and indoor venues bring their own acoustics. Hard-walled halls, glass-fronted function rooms and low ceilings each need a different approach. Arrive early enough to walk the room, clap once and listen to how long the sound lingers before deciding on speaker placement.
Coverage matters more than volume. Placing speakers so that they reach the whole audience evenly usually sounds clearer than turning a single pair louder. Where a room is long, delay speakers can keep the back rows intelligible without overpowering the front.
Speech events, which fill the calendar before the holidays, depend on intelligibility more than anything else. Choose microphones suited to the speaker, set a gain structure with headroom and keep a handheld on standby for the person who ignores the lectern.
Agree changeover times and cue points in advance with the producer. A short written running order shared with whoever operates the desk removes most of the guesswork on the night.
A short seasonal checklist to keep by the desk
Pulling these points together, the aim is simple: find faults while there is still time to fix them. A written list kept with the equipment is more reliable than memory, and it helps whoever covers for you when you are away.
Start with power and signal path, then move outward to microphones and monitoring, and finish by listening to the room itself. Record what you find and what you changed, with a date, so next year's check starts from knowledge rather than a blank page.
If a problem is beyond a quick fix, such as persistent noise, a room that will not behave or a monitoring setup that never translates, that is the point to ask for a second opinion. A fresh pair of ears often spots in minutes what has been tolerated for months.
Audio rarely announces trouble politely. A modest amount of attention now keeps the busiest weeks of the year calm.
- Power, cables and connectors first
- Microphones and wireless batteries next
- Monitoring from the listening seat
- Desk channels, scenes and firmware
- Room walk and speaker coverage before doors open
The coming months reward preparation. Dry, tested microphones, honest monitoring, a serviced desk and a considered plan for each room let the busy season run without audible surprises. None of these checks is complicated, and most take less time than a single troubleshooting session during a live event. Set aside an afternoon, write down what you find, and start the winter schedule knowing your sound chain has been listened to properly.
