Outdoor weddings: what nobody tells you about sound

A wedding on a country estate under oak trees at sunset is the picture everybody wants. It is also the most technically difficult setting there is. Not because the setup is complicated, but because there are no walls outdoors, and walls do half the work of sound.

1 · No walls means twice the equipment

Inside a hall, sound bounces and comes back. A modest system fills the room by itself. Outside, every wave travels outwards and never returns. The result is that the same equipment that is more than enough indoors sounds weak and thin ten metres from the DJ booth in a garden.

The practical consequence: for the same number of guests, an outdoor event needs roughly twice the power and, above all, subwoofers — bass is the first thing you lose outdoors. If an outdoor quote costs the same as an indoor one for the same capacity, either the indoor quote was expensive or the outdoor setup will fall short.

How to tell whether the system is properly sized

Ask directly: “How many watts and how many subwoofers for how many people outdoors?” You do not need to understand the answer. You need to check that the person has one.

2 · The wind carries the words away

At an outdoor ceremony, noise is not the enemy. Wind hitting the microphone capsule is. It produces a low rumble that swallows consonants and makes the officiant unintelligible at the most important moment of the day.

Three things solve it, and all three are inexpensive:

• Foam or furry windscreens on every microphone, including lavalier microphones.
• Lavalier microphones for the officiant and the couple, instead of one shared handheld microphone. They sit close to the body, where the wind hits less.
• Speakers aimed at the guests, not at the couple. It sounds obvious and is constantly done wrong.

3 · Power is the most expensive failure

A power cut at two in the morning is the worst thing that can happen, and it almost always has the same cause: the kitchen, lighting and sound system all connected to the same circuit breaker. Somebody switches on the fryer, the breaker trips and the party is over.

What you need the venue to confirm in writing before the wedding:

• The sound system has its own electrical circuit and circuit breaker, separate from the kitchen and lighting.
• The power outlet is less than 25 metres from the DJ booth. Beyond that, voltage drops and a heavy-gauge extension cable is needed.
• If the venue has no mains connection — increasingly common in the mountains — use a silenced generator with plenty of spare capacity. A generator running at its limit overheats and stops.

4 · The neighbours and the local council

This is what brings more weddings to an abrupt stop in Spain than anything else, and almost nobody checks it when booking the venue. Many municipalities in the Madrid Region have noise regulations with a cutoff time, and rural venues often have neighbours less than 300 metres away even if you cannot see them.

If somebody makes a complaint, you do not get a warning. The local police arrive and the event is over. There is no refund, and the venue operator may also receive a fine.

What to do, in this order:

1. Ask the venue in writing for the cutoff time and whether it holds a licence for musical events.
2. Ask whether a mandatory sound limiter is installed. Many venues already have one, and it cuts the power when the decibel limit is exceeded. The equipment has to be connected through it, and you need to know that in advance, not discover it that night.
3. Plan the set to finish at that time, with a chosen final song, instead of being caught halfway through a track when the cutoff arrives.

A trick that works

If the limit is 02:00 and the party is still going, many venues allow it to continue indoors, in an enclosed room, at a lower volume. Agree this in advance and bring a second, smaller system for that part. It is much cheaper than arguing about it on the night.

5 · What if it rains?

Electrical equipment cannot get wet. Not even slightly. Not even from dew in the early hours. Every outdoor setup needs a plan B agreed in advance: an enclosed marquee, a covered terrace or an indoor room the party can move into within twenty minutes.

Make that decision when signing the contract, not while checking the weather forecast the Thursday before. The question to ask the venue is simple: “If it rains, where will the dance floor be?” If there is no clear answer, you are the one accepting the risk.

Next step

If you already have a venue, send me its name and some photographs of the site. I will tell you what you need and which questions to ask before signing with them — even if you do not end up hiring me.
