Two-channel audio amplifier switches between three digital and analog audio sources. It downmixes multi-channel digital audio to 2.1 channels, and evens out the volume between different sources and program materials.
The GefenTV 2.1 Audio Amplifier w/ Volume Stabilizer is well-suited for use in home entertainment systems, offices, or meeting rooms. It features three audio inputs (TOSLINK®, S/PDIF, Analog L/R) for accommodating multiple audio sources. This product also incorporates a Dolby® Digital decoder to downmix 5.1 channels of audio to 2.1 channels. Dolby® Volume technology automatically outputs consistent audio levels regardless of the broadcast program type (commercials, movies, or TV shows). The GefenTV 2.1 Audio Amplifier w/ Volume Stabilizer provides amplification of up to 50 Watts per channel through the unit's speaker outputs, a line-level output for a powered subwoofer, plus additional line-level main L/R outputs. An RS-232 port is provided for automation. For easy access and control, use the front panel control buttons with an illuminated LCD display, or the included IR remote control.
Connect the audio input source(s) to the GefenTV 2.1 Audio Amplifier w/ Volume Stabilizer. Connect a pair of loudspeakers to the speaker output binding posts. Connect the supplied DB-9 serial cable from the RS-232 port to your home automation control device (if applicable). Plug in the included power supply to the 24V DC power jack on the rear panel of the unit. Connect the AC power cord to an available electrical 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.
