“How do I properly set the input sensitivity on my amplifier”
Please
refer to Appeaset the input sensitivity for maximum, low-
distortion output.
“My amplifier doesn’t turn on”
Check
the fuse, not just visually, but with a continuity meter. It is
possible for a fuse to have poor internal connections that
cannot be found by visual inspection. It is best to take the
fuse out of the holder for testing. If no problem is found with
the fuse, inspect the fuse-holder.
Check
the integrity of the connections made to each of the
“
+12VDC
”, “
Ground
”, and “
Remote
” terminals. Ensure
that no wire insulation is pinched by the terminal set screw
and that each connection is tight.
Check
UPNBLFTVSFUIFSFJT7BUUIF
“Remote”
connection of the
amplifier. In some cases, the turn-on lead from the source unit
is insufficient to turn on multiple devices and the use of a relay
is required. To test for this problem, jump the “
+12VDC
” wire
to the “
Remote
” terminal to see if the amplifier turns on. If this
does not work, proceed to the next step.
“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 terminal block.
Check
the input connectors to ensure that they all are making good
contact with the input jacks on the amplifier.
