1. IInnppuutt SSiiggnnaall - Connect these RCA
jacks as described in the Front
Panel Connection section of this
guide.

„ Set the slave/master switch
on the master amplifier to the
MASTER position.
„ Set the slave/master switch
on the slave amplifier to the SLAVE
position.
„ Setting the slave/master
switch on both amplifiers will auto-
matically set the I/O RCA jack
configuration according to each
amplifiers slave or master designa-
tion.
NNOOTTEE:: Amplifiers in this combination can only be
connected in matched pairs. Multiple matched
pairs may be added to drive separate subwoofer
loads in a given system.
3. RReem moottee SSuubb LLeevveell CCoonnttrrooll -
Connect the Remote Sub Level
control to the master amplifier
only. The master amplifier gain
control is used to set the overall
gain for both amplifiers, and
then the Remote Sub Level
control can adjust the gain of
both amplifiers.
4. SSiiggnnaall CCoonnnneeccttiioonn - Connect an RCA
cable between the BRIDGE OUT RCA
jack of the Master amplifier and the
SLAVE IN RCA jack of the Slave
amplifier as shown in Figure 6.
5. SSuubbw wooooffeerr SSppeeaakkeerr CCoonnnneeccttiioonn - In
this amplifier combination the
Subwoofer speaker terminals of
both amplifiers drive common
subwoofer(s). Use the following
speaker connection diagram when
connecting the subwoofers to the
amplifiers. Connect the amplifiers
speaker terminals to any combina-
tion of one or more subwoofers that
results in a nominal impedance
between 2 and 4 ohms. DO NOT
connect loads of less than 2 ohms
when connecting to amplifiers in
the External Synced Bridged combi-
nation.
W WAARRNNIINNGG:: Two wires of 12AWG minimum must be
connected between the negative sub out termi-
nals of the master and slave amplifiers.
