  • Volume Controller Knob Style with Self-Impedance Matching OSD Audio SVC100 The OSD Audio SVC100 Knob-style Volume Control is one of our most popular models.
  • Rated at 100 Watts peak, this unit shares the same capabilities as the slider version and is built with close attention to performance, reliability and durability.
  • Some folks prefer the knob control over the slider type which is why we offer both.
  • As you can see by the many reviews, the result is a blend of transparency and functionality, with low distortion and ruler flat frequency response.
  • The unit comes with White, Ivory or Almond faceplates and whether you go with knob control or soft-touch sliders, OSD Audio offers convenience and style with colors to match any decor.
  • Ê Features • Control volume from any room • Wall-mounted volume controller works with any audio/video system • Low distortion and ruler flat frequency response • All installation materials includedÊ What Is Impedance Matching? Volume controls do not add gain (volume) to your system but attenuate the volume up or down.
  • The sound source is turned up to optimum levels and the volume control reduces the sound to almost inaudible levels.
  • There are two types of volume controllers: Impedance matching and Non-impedance matching.
  • A basic multi-room system will typically have an amplifier/receiver, a speaker selector, 4 to 8 pairs of speakers, and volume controls.
  • To protect the amp, the speaker selector has impedance matching that you can turn on or off (manually) depending whether you have impedance matching volume controls.
  • More complex multi-room systems often have a volume control for each pair of speakers that is attached to the speaker selector.
  • Impedance-matching VCs offers more precise protection for the amplifier/receiver versus the protection built into the speaker selector.
  • Remember, when adding impedance matching, you must turn off (disable) the protection in the speaker selector.
  • Most impedance-matching volume controls feature three standard settings: 1/2x, 4x and 8x, while some add a 16-ohm setting like our VMS series.
  • These settings correspond to a chart in the owner’s manual based upon the type of amplifier (4 or 8 ohm) and the number of 4 or 8 ohm speakers that you will be using in the multi-zone/room/speaker system.
