I am helping a friend with the A/V portion of his basement renovation. We are running a component matrix for video and distributed audio to several zones. He wants the option to play TV audio over the in-ceiling speakers instead of the distributed audio. Fine, so we got an audiosource Amp100 for each zone so I can run the TV audio out to the secondary input on the amp. Functionaly, everything works as intended, but the audio level coming out of the TV is much too low and I need to crank the amp way up. This puts the volume level way out of whack compared to the audio distribution from the CD player, etc. If you forget to turn the volume on the amp down before switching from TV to distributed audio, the system blasts the speakers. I need a line level booster/preamp to bring the level from the TV up to the proper strength, like the rest of the system. Any suggestions? Thanks!!!
