How to control the volume of a 100V Line or low impedance loudspeaker using an attenuator
Loudspeaker volume controls (also known as attenuators) enable you to control the volume of either one or a series of 100V Line / low impedance loudspeakers.
Our range includes a series of wall or desktop attenuators giving you full control of the volume.
Attenuators are commonly used in commercial environments such as Pubs, Restaurants, and Hotels where a localized volume control is required, This is particularly useful if you have multiple rooms and you need to reduce the volume in a certain area such as a restaurant connected to a bar.
The attenuators are available is a range of wattages from 12w to 120w and are compatible with all our wall and ceiling speakers via a 100v line or low impedance system.
How do I know which volume control I need?
When using an attenuator it's important to make sure the load (total wattage) of the speakers does not exceed the max wattage of the volume control. In our simple guide below you can see an example of load/wattages
Volume Control Loading Examples:
1 x 20W 100v Loudspeaker = 20W Volume Control
6 x 10W 100v Loudspeakers = 60W Volume Control
8 x 15W 100vLoudspeakers = 120W Volume Control
20 x 6W 100v Loudspeakers = 120W Volume Control
For low impedance music systems, you simply need to balance the impedance to suit the volume control.
1 x 8 Ohm Loudspeaker = 8 Ohm Volume Control
2 x 8 Ohm Loudspeakers = 4 Ohm Volume Control
1 x 16 Ohm Loudspeaker = 16 Ohm Volume Control
2 x 16 Ohm Loudspeakers = 8 Ohm Volume Control
We are key stockists of Volume controls from Adastra, Clever Acoustics, Monacor and TOA.
Speaker attenuators can either be wall mounted or installed into a 19" rack cabinet. Wall mount volume controls fit into standard UK back boxes and sit flush mount to the wall. 19" Rackmountable attenuators are also available for installing into a rack cabinet.
