SX2 1200.6
6 CHANNEL POWER AMPLIFIER
LINE IN
Connect preamp signal cables from the source unit to
these terminals. Use of 4 OR 6 channels of input signal
selectable with INPUT MODE switch.
INPUTS
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.

CH 3+4 Controls
Use in conjunction with MODE switches. Selectable
disabled (FLAT), Highpass (HP) or Bandpass (BP)/Lowpass
(LP).
Select FLAT/HP/LP/BP then adjust to desired crossover
point, variable from 55Hz - 4kHz @ 12dB per octave. If LP or
BP is desired, move both switches to LP+LP or BP+BP. If Flat
or HP is selected, secondary LP/BP switch is disabled.
5+6 PEAK
Peak output LED indicator for channels 5+6. 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.
CH 5+6 Controls
Use in conjunction with INPUT MODE switches. Note:
Selecting CH5-6 on INPUT MODE will disable 5-6 controls
with exception of level. Highpass/subsonic/bypass (HP),
Lowpass (LP).
Select then adjust to desired crossover point, variable from
55Hz - 4kHz @ 12dB per octave.
LPF/ HPF
Select LPF for subwoofer applications, will also activate
REMOTE input. Select HPF for use with external processor or
for full range applications. HP disables crossover functions.

INPUT MODE

Input signal selectable for 4 or 6 channels. If only 4 channels of
input signal are available, select 1-4 to allow signal to split to CH5-
6. Selecting 5-6 will allow seperate signal input but will disable
crossovers and RBPC controller. With 5-6 active, only level will
remain functional.
HP 1+2
Use in conjunction with MODE switch. Selectable disabled (FLAT) or
Highpass (HP). If HP is selected, then adjust dial to desired crossover
point, variable from 55Hz - 4kHz @ 12dB per octave.
LEVEL
Input sensitivity, used to properly match input signal levels from
signal source and maximize amplifier output while eliminating noise.
Level is not a volume control, level matching only. Adjust LEVEL to
match source output voltage. For reference, a typical aftermarket
radio ranges from 2v-4v of output. At minimum, use of a multi-meter
and test program material is critical for this step. Independent level
controls available for channels 1+2, 3+4 and 5+6.

HP
HP adjusts a highpass crossover that can be used as a subsonic
filter. Use in conjunction with LPF/ HPF switch. If LPF is selected, then
adjust HP dial to desired crossover point, variable from 10Hz - 50kHz
@ 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
Speaker connections can be configured in Stereo (1 and 2, 3 and
4 or 5 and 6), Mono (1+2, 3+4 and 5+6) and 5 channel (1 and 2,
3 and 4, 5+6). Minimum speaker impedance is 2Ω in Stereo or 4Ω
Mono. When bridging the amplifier into a Mono load, only the 1 +
and 2 –, 3 + and 4 - or 5 + and 6 - outputs on the bridged channels
will be used. Accepts up to 10GA wire.
