5.) Replace the fuse with the appropriate size (see
#6 below), and press the fuseholder back into the AC inlet
until it latches.
6.) Using a power cord of the appropriate size
and with the appropriate terminations, plug the cord into
the rear of the amplifier and then into the wall. The
Powerflex amplifier is now ready for use at the new mains
voltage.
If the mains voltage is 110-125VAC, the required
fuse is MDA 12, 250V, and the required power cord is 3-
wire grounded, 13 Amp (16AWG) minimum.
If the mains voltage is 220-250VAC, the required
fuse is MDA 10, 250V, and the required power cord is 3-
wire grounded, 10 Amp (18AWG) minimum.

Speaker Outputs
The Speaker outputs are provided on screw ter-
minal barrier strips with security covers. The output screw
terminals will accept spade lugs or stripped wire for wire
sizes 10 to 22 gauge.

In bridge mode, the speaker output con-
nections are taken from the two (+) screw terminals where
the odd-numbered channel (+) output is the positive con-
nection and the even-numbered channel (+) output is the
negative connection.
CAUTION: NEVER CONNECT THE TWO (+)
SCREW TERMINALS TOGETHER OR CONNECT A (+)
SCREW TERMINAL TO A (-) SCREW TERMINAL.

SELF-PROTECTION FEATURES
Powerflex 70V amplifiers contain circuitry to self-
protect during extreme fault conditions. These fault con-
ditions are:
1.) Power supply undervoltage
2.) Power supply overvoltage
3.) Output overcurrent
4.) Heat sink overtemperature
5.) Unacceptable DC or high frequency output content
6.) AC power interruption
-
Except for AC power interruption, the detection
of any fault will result in the activation of protection cir-
cuitry on a particular module, which consists of two chan-
nels. That is, a short circuit on the output of channel 1
-
will result in both channel 1 and channel 2 entering pro-
-
tect mode. This is because the signal processing module,
which processes both channels simultaneously, does not
distinguish between the two channels within a channel pair
-
when processing a fault.
