BEFORE PROCEEDING SET THE VOLUME CONTROL ON THE TVA50 TO THE MINIMUM POSITION (FULLY COUNTERCLOCKWISE).

1.Play a source (CD, Tuner) on the whole-house system. Set the volume to a normal listening level.

2.Turn the TV on. The TVA50 will sense the TV power, activate and switch to the local source (TV).

3.Using the remote control for the TV or the volume control on the TV, turn the volume on the TV all the way up. (Use the on-screen volume bar or numeric display for reference).

4.Slowly turn the volume control on the TVA50 clockwise, until the audio from the TV is coming out of the speakers at the loudest level that will ever be used. (If the sound is distorted, reduce TV volume.) This will be the maximum level the TV will play through the TVA50 and speakers.

5.Reduce TV volume to a normal listening level.

6.Turn the TV off. The system should switch back to the whole- house system. Properly tuned, the speaker level from the whole-house system and TV should be about the same at a normal listening level.
