Design Features
A. 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
B. Power Connector terminals: Connects Power, Ground, and Remote
C. High Level (Speaker) Inputs: (Models S4.500.1, S4.200.2 and S4.400.4 Only) The high level
inputs use a detachable connector terminated with 20 AWG leads. These inputs should be used if
the source unit has only speaker line (high level) outputs and not RCA outputs.
D. 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.
E. Level Control: The input level control is preset to match the output of most source units.
This can be adjusted to match output levels from a variety of source units.
F. Crossover Filter Switch: High for High Pass - Mid-Tweeter.
G. Adjustable Crossover Frequency Control: 50-500Hz @ 12dB/octave. 50-250Hz Low Pass
only on Model S4.1000.1D.
H. Remote Level Control: (Model S4.1000.1D Only) Attenuates Gain set on the amplifier by
up to -12dB
I.
Speaker Connections: Follow correct polarity, and do not Ground any speaker wires. Do not
connect any speaker wires together.
J. 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.
K. Subsonic Control: (Model S4.1000.1D Only) A variable 15-40Hz 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.
L. Master / Slave Switch: (Model S4.1000.1D Only) Used to set the amplifier to master or
slave when strapping.
M. SLV IN (slave): (Model S4.1000.1D Only) When strapping, this is the slaved amplifier input
from the master amplifier.
N. MAS OUT (master): (Model S4.1000.1D Only) When strapping, this is the master amplifier
output to the slave amplifier.
