5) dedICATed CIRCUIT BReAkeR: each amp will require
a dedicated circuit breaker for its full output. There will be
a sustained loss of power if the AC voltage falls below the
rated 120V or 230/240V input. Normally a 2000w amp or
higher would require its own 20 amp circuit to deliver its
full power at 2 ohms/channel or 4 ohms bridged.
1) No SoUNd FRoM CH 2: The rear (recessed) BRIdGe
switch has been inadvertently pushed in.
2) STeReo CHANNelS SoUNd THe SAMe: The rear
PARAllel switch has been inadvertently pushed in.
3) No HIGH FReqUeNCIeS: Tweeters or midrange drivers have
been damaged or blown from feedback or to much power.
4) PooR SoUNd (BASS): The speaker systems are wired out
of phase to each other. To correct, check polarity and if nec-
essary reverse the wires on one speaker connector only and
your sound, especially the bass will improve.

can be used while in
Bridged mode.
Connect the DCM1015 in
“bridge mode” to deliver 70
volts. Higher powered amps
will exceed 70v, damaging
