Product Description
Outdoor Speaker Volume Controller in Gray
This unit comes in a weatherproof, sealed enclosure - suitable for outdoor installations.
It features rotary design that allows you to set the audio to the desired listening level.
Water resistant enclosure - can be used for marine (boating) applications.
The rotary control can be set to one of 12 positions, including the minimum (off) and maximum volume settings.
When setting up the speaker volume controls, it is important to match the impedance of the speaker system with the load rating of the amplifier. This is done by setting the jumpers on the volume control to compensate for the number of speakers you have in a parallel configuration and the impedance level of the speakers.
If using a single pair of speakers rated at the same load level as your amplifier, you do NOT need to make any changes - just leave the jumper in the default x1 position. If the speakers are of a different impedance level and/or you have more than one set of speakers in parallel, please refer to the following chart as a guide for setting the jumpers on the speaker volume control.
Warning - any speakers wired in series, the overall impedance level is the sum of each speaker. Example - two 4 ohm speakers wired in series is the same impedance as a single 8 ohm speaker.
