Field Discount TV Antenna Installations

Showed me nothing about the Amplifier (Cambridge Audio 851A Amp) which was the reason I wanted him here. Told him that I had setup the Tuner to input 3 and because the XLR cables were input 1 then they should show up as input 1. Wanted to know more about balanced/unbalanced inputs but to no avail. Waste of 15 minutes and $'s, not a happy camper. I suppose I will have to read the Manual again and again which really doesn't tell you much but hey, that's all I have.
