MicroSub+ / PowerWedge+ with DCD™ Amplifier Technology 7
Problem Possible Cause Solution
How to properly set
input sensitivity
Please refer to Appendix A to set the input sensitivity for
maximum, low-distortion output.
Amplifier doesn’t
turn on
Faulty fuse
Remove fuse and check with continuity meter. Replace if
necessary.
Poor connection
integrity
Check “+12 VDC”, “GND”, and “Remote” leads for pinched
wires; ensure tight connections.
Insufficient “Remote”
input
Make sure there is a sufficient +12V supply at the “Remote”
connection; if not, a relay may be required.
Intermittent output,
fluctuates when I tap
on it or hit a bump
Poor connection
integrity
Make sure wiring insulation has been properly stripped back
at connection points for good contact area.
Make sure the signal input connections (low-level or high-
level) are making good contact.
Output shuts off after
a while
Overheating condition
(Thermal Protection)
Make sure enclosure is positioned allowing the amplifier
adequate space for ventilation and heat dissipation.
