Ethereal VS100 Impedance Matching Volume Control

SKU CH-VQZN-RV95Z

Impedance-matching slider volume control rated at 63 watts per channel with selectable 2x, 4x and 8x settings, accepts up to 12 gauge speaker wire and includes white, ivory and bone wall plates

  • Delivers 63 watts per channel for strong audio performance
  • Selectable impedance at 2x, 4x and 8x matches diverse speaker loads
  • EMI/RFI filter attenuates noise up to 58 dB for cleaner sound
  • Accepts up to 12 gauge speaker wire for flexible wiring options
  • Includes white, ivory and bone wall plates for decora or standard installation

Impedance Matching Volume Control

The Ethereal VS100 is a slider-type impedance matching volume control designed for multi-room audio installations. It handles up to 63 watts per channel and provides selectable impedance settings at 2x, 4x and 8x to protect amplifiers when driving multiple speaker pairs.

Included Wall Plates

The unit ships with White, Ivory and Bone coloured wall plates for standard or decora single-gang installation. This allows immediate aesthetic matching to common interior finishes without purchasing separate cover plates.

Pre-Installation Checks

Verify that your amplifier's output per channel aligns with the 63-watt rating and that your speaker wiring is 12 gauge or thinner. Confirm the intended mounting location fits a standard single-gang box and that the required impedance multiplier matches your speaker configuration.

Questions about this item

Will the 12 gauge speaker wire terminals need any periodic tightening or replacement?

The terminals accept up to 12 gauge speaker wire and are designed for a permanent installation behind the wall plate; no routine tightening or replacement is required.

At continuous 63 watts per channel, what is the first limit the VS100 will hit — thermal, impedance or attenuation headroom?

The unit is rated for 63 watts per channel with selectable 2x, 4x and 8x impedance settings; the impedance multiplier you choose determines the load presented to the amplifier, so that setting is the practical limit under sustained use.

Does the VS100 generate audible noise or noticeable heat when it runs all day at full power?

The device is a passive impedance-matching volume control with a 100 watt EMI/RFI filter providing up to 58 dB attenuation; it has no active circuitry, so it produces no fan noise and negligible heat during all-day operation.
