Niles WVC100E Grey FG00965 100 Watt Weatherproof Surface Mount Volume Control
The WVC 100E is a weatherproof stereo impedance-magnifying volume controls that connect between the speaker-level output of an amplifier, speaker selector, or a Niles VCS HUB8 distribution hub and your speakers.The WVC 100E is a freestanding volume control mounted in a PVC junction box for use in environmental where a wall-mounted volume control would be impractical. Both models adjust the volume of remotely located speakers to which they are connected by attenuating the amplifier signal. To assure minimal dissipation of internal power with virtually no power wasted as heat, Niles volume controls use autoformers instead of L-pads as the volume-controlling element.The WVC 100E in an impedance-magnifying (IM) volume control. Unlike other brands, they have additional autoformer windings that magnify the impedance of connected speakers, while allowing all 12 steps to adjust the volume of the sound. Switches on the PC board select these windings.With the volume control providing impedance protection for your amplifier, you can create systems with no additional impedance-matching devices between the volume control and the amplifier.
