Amplifier Owner's Manual
LINE IN
Connect preamp signal cables from the source unit to these
terminals.
LINE OUT
Used to connect multiple amplifiers without degrading
signal strength via internal line driver. Also utilized when
connecting amplifiers together in a Master/Slave
configuration (See Master/Slave).
BAL / UNBAL
Select Balanced or Unbalanced inputs based on your input
source's design for best S/N performance.
AUTO ON
Auto-on is useful when connecting to an OEM system
that does not offer a Remote turn-on lead to activate the
amplifier. When connecting directly to the amplifier using
a high-level input signal the circuit can detect the input
voltage (BTL <1v DC) and activate the amplifier. If your
system has a standard remote turn-on lead use the standard
REM input. If it is an OEM system that stays active even with
the radio off (voltage on signal wires) move the switch to
the OFF position and locate an alternative circuit or PAC
L.O.C. PRO device to activate the amplifier. See Source
Balanced/Unbalanced for High Level input wiring.

40Hz EQ
Up to 6dB of bass boost @ 40Hz. Adjust this with the mindset
of less is more as usually only minor adjustments (if any) are
needed for most modern systems. Most systems will benefit
from proper Phase adjustment without having to use boost.
LP
Variable lowpass crossover frequency adjustment from
40Hz - 240Hz @ 24dB per octave.
REMOTE
Selecting LP activates this port. This port is for connecting
the (RBPC) remote bass level and phase controller with
BASS SHIFT . The unique feature of the RBPC with BASS
®
SHIFT® allows for perfect adjustment of not only the
subwoofer level but also 0-180° of phase adjustment from
the listening position. Properly adjusting phase will allow
enhanced bass response, dynamics and impact at any
volume. To adjust, play a test tone close to the crossover
overlap you have the system adjusted to, typically in the
50-100Hz range. With all system speakers playing and at
a moderate volume, slowly adjust the phase dial on the
RBPC across the entire range. When the subwoofer is in
phase with the other speakers in the system, you

MASTER / SLAVE
Select Master if single amplifier or not connecting multiple amplifiers
in either Strapped or Linked mode. Strapped mode will allow two
SX2 1200.1 amplifiers to be combined together as a single amp
and drive a 2Ω load in excess of 2400 watts. Linked mode will allow
any number of SX2 1200.1 amplifiers to be connected to a Master
SX2 1200.1. Allowing all connected amplifier adjustments to be
made via the Master amplifier. See diagrams for correct wiring
configurations.
LP/ FLAT
Select LP for subwoofer applications, will also activate REMOTE
input. Select FLAT for use with external processor or for full range
applications.
HP
HP adjusts a highpass crossover that can be used as a subsonic
filter. Use in conjunction with LP/ FLAT switch. If LP is selected, then
adjust HP dial to desired crossover point, variable from 10Hz - 120Hz
@ 24dB per octave. Typically used for vented subwoofer systems
and is adjusted to the port tuning frequency to prevent overdriving
of the subwoofer.
PHASE
Set to 180° on amplifier to allow adjustment from RBPC. The unique
feature of the RBPC with BASS SHIFT
of not only the subwoofer level but also 0-180° of phase adjustment
from the listening position. Properly adjusting phase will allow
enhanced bass response, dynamics and impact at any volume.
If not utilizing the RBPC, adjust phase directly from amplifier. See
RBPC instructions for proper adjustment.

SPEAKER
should be able to detect a rise in volume, "the sweet spot." Now
return the control to the sweet spot and make small adjustments
+/- until you maximize the output. You have now completed
adjusting the phase and should not have to adjust this again. Use
the level control to adjust the subwoofer output to your preference
based on music program material. NOTE: To allow adjustment from
the RBPC controller, the phase adjustment must be set to the 180°
position on the amplifier.
PEAK
Peak output LED indicator. Helpful when used for subwoofer level
adjustment. Adjust LEVEL so PEAK LED flashes when driving amplifier
hard, but not so much that the LED stays on continuously. Light will
illuminate when rated output voltage is achieved.
FULL RANGE USE
SX2 Monoblocks are full range capable. Unlike traditional
monoblocks that are only used in bass applications, the SX2 1200.1
can be configured for use as a powerful mono amplifier or used in
pairs to create an incredibly powerful stereo output. Applications
such as driving a large number of full range speakers with 1200
watts per channel or a strong component set with unlimited
channel separation with independent left and right amplifiers.
