THANK YOU
for purchasing a JBL CS Series amplifier.
In order that we may better serve you should you require
warranty service for your new amplifier, please retain your
original purchase receipt and return the enclosed warranty
registration card.
APPLICATIONS – CS200.1
The CS subwoofer amplifiers are
single-channel amplifiers. There are
two sets of terminals to make it easy
to connect multiple woofers. Either
set of (+/–) terminals may be used when
connecting woofers.
To the right are two application
diagrams to help plan your subwoofer
system installation. Figures 2 and 3
show how to configure the CS200.1
subwoofer amplifiers.
NOTE: For simplicity, Figures 2 and 3
do not show power, remote and input
connections.
Figure 2. CS subwoofer amplifier with two
woofer connections.
Figure 3. CS subwoofer amplifier with one woofer
connection.
NOTE: Minimum speaker load is
2 ohms.
APPLICATIONS – CS50.4
The CS50.4 can be set up for stereo
4-channel, 3-channel or bridged
2-channel operation, as shown in
Figures 4 through 6.
NOTE: For simplicity, Figures 4 through 6 do
not show power, remote and input
connections.
NOTE: Minimum speaker impedance for
stereo operation is 2 ohms.
Minimum speaker impedance for bridged
operation is 4 ohms.

operation to drive front and rear full-range speakers.
Figure 5. CS50.4 is set up for 3-channel operation to
drive a set of full-range speakers and a subwoofer.
Figure 6. CS50.4 used in bridged 2-channel mode
to drive a set of components or subwoofers.

SENSITIVITY
• 1 x 236W RMS channel at 4 ohms and ≤1% THD + N
• Signal-to-noise ratio: 100dBA (reference 1W into 4 ohms)
• 1 x 338W RMS channel at 2 ohms, 14.4V supply and
Determine your system plans and set the
crossover mode switch accordingly. If
you plan to use the CS50.4 to drive full-
range speakers, set the crossover mode
to FLAT and skip to “Setting Input Sensi-
tivity.”
1. Initially turn the INPUT LEVEL control(s)
to minimum (counter clockwise).
2. Reconnect the (–) negative lead to the
vehicle’s battery. Apply power to the
audio system and play a dynamic music
track.
3. On the source unit, increase the vol-
ume control to 3/4 volume. Slowly
increase the INPUT LEVEL control(s)
toward three o’clock until you hear
slight distortion

declare in own responsibility that the product
described in this owner’s manual is in compliance
with technical standards:
Initially set the crossover frequency
control midway. While listening to music,
adjust the crossover for the least per-
ceived distortion from the speakers,
allowing them to reproduce as much bass
as possible.

in the music. Then reduce the INPUT
LEVEL slightly until distortion is no
longer heard.

Systems using a separate subwoofer set
the crossover mode to HP (high pass) for
your full-range speakers. Adjust the
crossover frequency to limit bass and
provide increased system volume with
less distortion.

NOTE: After the source unit is on, blue
LEDs (on the top panel) will light, indicat-
ing the amplifier is on. If not, check the
wiring, especially the remote connection
from the source unit. Also refer to
• 4 x 67W RMS channels at 4 ohms and ≤1% THD + N
• Signal-to-noise ratio: 86dBA (reference 1W into 4 ohms)
• 4 x 82W RMS channels at 2 ohms, 14.4V supply and
≤1% THD + N

• Dynamic power: 145W at 2 ohms
• Effective damping factor: 6.395 at 4 ohms

For subwoofers, choose the highest
frequency that removes vocal information
from the sound of the subwoofer.
