“MY AMPLIFIER’S OUTPUT FLUCTUATES WHEN I TAP ON IT OR HIT A BUMP”
Check the connections to the amplifier. Make sure that the insulation
for all wires has been stripped back far enough to allow a
good contact area inside the amplifier terminal.
Check the RCA connectors to ensure that both the center pin and
the outer shield are making good contact with the input jacks
on the amplifier.
“HOW DO I PROPERLY SET THE INPUT SENSITIVITY ON MY AMPLIFIER”
Please refer to Appendix B (page 14) to set the input sensitivity for
maximum, unclipped output.
