The Gefen GTV-VOLCONT-DA is a GefenTV 2.1 Audio Amplifier with a Volume Stabilizer. It switches between analog and digital Audio inputs with Dolby AC3 Decoding (mix-down from 5.1 to 2.1) and Dolby Volume Technology for Auto Volume Stabilization plus 25 watts per channel Amplification.

The GefenTV 2.1 Audio Amplifier w/ Dolby¨ Volume Stabilizer is well suited for use in small home entertainment systems or as an add-on audio processor to any computer audio output. It offers three audio inputs (TOSLINK, S/PDIF, Analog L/R) for multiple audio sources. The product also incorporates a Dolby AC3 decoder to downmix 5.1 to 2.1 channels of audio. Dolby Volume technology automatically outputs consistent audio levels regardless of the program type (commercials, movies, or TV shows). The GefenTV 2.1 Audio Amplifier w/ Volume Stabilizer provides amplification of up to 25 Watts per channel (Left and Right) fed through the unit's speaker output binding posts plus line-level output for a powered subwoofer. This product switches to standby mode when not in use and is Energy StarŞ compliant. An RS-232 port is provided for home automation control. For easy access and control, use the front panel control buttons with an illuminated LCD display, or the included IR remote control from several feet away.

How It Works
Connect the audio input source(s) to the GefenTV 2.1 Audio Amplifier w/ Dolby Volume Stabilizer. Connect the speakers using speaker wires (not included) to the Speaker Output binding posts. Connect the included RS-232 cable from the RS-232 port to your home automation control device (optional). Plug in the included power supply to the 24V DC power jack on the rear panel of the unit and to a power outlet. Use the front panel buttons or the included IR remote to control the front panel display menu functions, Mute, Input Select, Bypass, and Standby mode.
