The Gefen GTV-VOLCONT is a GefenTV Auto Volume Stabilizer product is a high-quality volume stabilizer. It actually makes the volume adjustments in such a subtle way that you won't even notice the change.

An additional feature includes a bypass button that allows the pass-through of unmodified incoming audio. Using Dolby Volume technology, the unit senses changes in volume levels, and then maintains a steady volume level for any input sound coming from DVD, Blu-ray Disc or multimedia source. Listen to movies and TV shows easily without the inconvenience of continuously fiddling with the volume levels.

How It Works
Place the GefenTV Auto Volume Stabilizer somewhere close to where you want to connect it. Connect the audio source into the back of the unit (either digital audio or analog). Connect the audio output of the unit to an A/V receiver.

Connect the included 5V DC external power supply to the back of the unit. The LED in the front will light up red showing that the unit is in "standby mode." Next push the "Bypass" button or press the "Power" button on the supplied I/R remote control, and the LED next to the "Bypass" button will go out while one of the three audio input LEDs will also light up bright blue. This corresponds to the chosen audio input at the back. Press the audio selector buton at the back of the unit to select the audio input type.

Press the "Bypass" button again. The unit will be in "Bypass" mode; no sound is stabilized, and the bright blue LED next to the "Bypass" button will be lit up. Put the unit in standby mode (using only 1W of power) by holding the "Bypass" button until the LED next to the "Bypass" button lights up red.

Note: The GefenTV Auto Volume Stabilizer comes with analog (L/R) and digital (TOSlink, S/PDIF) audio inputs and outputs, and has a selector that determines which audio is stabilized.

Question: I have files on an mp3 player recorded at different levels, and when I play it through my stereo receiver, the files playback at different volume levels. If I put the Gefen volume stabilizer between the mp3 player and the receiver will all files playback at the same volume level?
Answer: Thank you for your inquiry. In theory, yes this product would stabilize the volume between MP3 tracks. However, because the quality of MP3s can vary widely, we are not 100% sure the performance would acceptable.
