jacks as described in the

Front

Panel Connection section of this
guide.

wiittcchh

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. PPhhaassee SSw

wiittcchh - Set the phase

switches of all synced MASTER
amps to 0°. Set the phase switches
of all synced SLAVE amps to 180°.
The master and slave amps must be
set to the opposite phase mode in
order for External Synced Bridged
operation to work.

4. In order to achieve safe, optimal

performance, the LPF, Bass EQ, and
Subsonic Filter controls on all

synced amps must be set to the
same position.

5. SSiiggnnaall CCoonnnneeccttiioonn - Connect an RCA

cable between the OUT RCA jacks
of the Master amplifier and the
INPUT RCA jack of the Slave ampli-
fier as shown in Figure 6.

6. 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.

WAARRNNIINNGG:: Two wires of 12AWG minimum must be

connected between the negative sub out termi-
nals of the master and slave amplifiers.

WAARRNNIINNGG:: The amplifier’s gain control is bypassed

completely in SLAVE mode. Do NNOOTT move the
MASTER/SLAVE switch to SLAVE position when
the amplifier is connected and playing. Do NNOOTT
connect any signal source to the amplifier in
SLAVE mode that exceeds 200mV.
