When I remove the preamp I can get Fox (channel 7 / 2.1) at 45-50 strength, but every other channel loses between 40 and 50 or disappears completely.
W/out preamp:strength
Ch 7 45-50
Ch 21 20-25
Ch 41 30-40
Ch 43 0-15
Ch 45 45-55
W/ preamp
Ch 7 0
Ch 14 55-60
Ch 21 70-75
Ch 28 20-25
Ch 29 85-90
Ch 39 55-60
Ch 41 75-80
Ch 43 45-50
Ch 44 50-55
Ch 45 75-80
Ch 50 60-70
Ch 51 30-35
I'm new to this, but why would the preamp "kill" one weak channel (7) while helping all the others?
