Keep the volume constant while enjoying TV or music

Ensure the same volume output from your multimedia program, regardless of input level. The GefenTV Auto Volume Stabilizer is located close to your TV, resulting in stable, consistent and smooth sound levels, accepting two-channel LPCM or L/R analog audio input types. Use the bypass button on the front of the unit, or via the IR remote, to flip between movies, which have a wide dynamic range, and TV, where the volume can vary considerably between program output and commercials.

How It Works

Place the GefenTV Auto Volume Stabilizer near your TV or A/V receiver. Route your audio sources into the input side of the Stabilizer. Feed the audio output to your TV or A/V receiver. Power up all connected equipment. Select the active audio source using the input selector buttons or the included IR remote. Sit back and and enjoy volume-stabilized audio on its own or with video.

Note:  Use the GefenTV Auto Volume Stabilizer to switch easily between digital and analog sources. All outputs will remain active.
