A. RCA Input Jacks – Line Level from Radio Pre-outs: The industry standard RCA jack
provides an easy connection for signal level input. They are platinum to resist the signal
degradation caused by corrosion.
B. Gain Control: The input gain control is preset to match the output of most source units.
They can be adjusted to match output levels from a variety of source units.
C. Adjustable Crossover Frequency Control: 50-250Hz. Low Pass only on Models
X1.1000.1D & X1.2000.1D.
D. Speaker Connections: Follow correct polarity, and do not Ground any speaker wires. Do not
connect any speaker wires together.
E. Crossover Filter Switch: (Models X1.400.2 & X1.800.4 Only)
HPF for High Pass - Mid-Tweeter.
Flat for All Pass - Full Range.
LPF for Low Pass - Subs.
F. Pass Thru Outputs: The Pass-Thru provides a convenient source for daisy-chaining an
additional amplifier without running an extra set of RCA cables from the front of the vehicle
to the rear amplifier location.
G. Power Fuse: If this Fuse should blow, determine the cause or see your authorized dealer.
Never replace the fuse with one of greater value than the original
H. Power Connector terminals: Connects Power, Ground, and Remote
I. Phase: (Models X1.1000.1D & X1.2000.1D Only) Used to vary the inversion of the output,
0°-180°, from input source.
J. SubSonic: (Models X1.1000.1D & X1.2000.1D Only) A high pass filter designed to prevent
frequencies below the audio range from being applied to the subwoofer from the amplifier.
Improving subwoofer performance and power handling.
K. Bass EQ: (Model X1.1000.1D & X1.2000.1D Only) Variable 20-80Hz frequency control. Boost
controlled by remote.
L.
Remote Level/Bass EQ Control: (Models X1.1000.1D & X1.2000.1D Only) Remote level
control attenuates Gain set on the amplifier by up to -20dB. Bass EQ control is 0 to +12dB
Boost of the frequency (20-80Hz) set on the amplifier.
M. Master / Slave Switch: (Model 2000.1D Only) Used to set the amplifier to master or slave
when strapping.
N. SLV IN (slave): (Model X1.2000.1D Only) When strapping, this is the slaved amplifer input
from the master amplifier.
O. MAS OUT (master): (Model X1.2000.1D Only) When strapping, this is the master amplifer
output to the slave amplifier.
