owner’s manual
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 amplifier is a
single-channel amplifier. 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 amplifier.
NOTE: For simplicity, Figures 2 and 3
do not show power, remote and input
connections.
Figure 2. CS subwoofer amplifier with two woofers
connected.
Figure 3. CS subwoofer amplifier with one woofer
connected.
NOTE: Minimum speaker load is
2 ohms total.
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. Set
crossovers according to application.

CROSSOVER(S)
SENSITIVITY
• 236W RMS x 1 channel at 4 ohms and ≤1% THD + N
• Signal-to-noise ratio: 100dBA (reference 1W into 4 ohms)
• 338W RMS x 1 channel at 2 ohms, 14.4V supply and ≤1% THD + N
• Dynamic power: 464W at 2 ohms
• Effective damping factor: 6.395 at 4 ohms
• Frequency response: 10Hz – 302Hz (–3dB)
• Maximum input signal: 7.5V
Determine your system plans and set
the crossover mode switch accordingly.
If your system design does not include
a subwoofer with the CS50.4, set the
crossover mode to FLAT and skip to
“Setting Input Sensitivity.”
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 volume
control to 3/4 volume. Slowly increase
the INPUT LEVEL control(s) toward three
o’clock until you hear slight distortion
in the music. Then reduce the INPUT
LEVEL slightly until distortion is no
longer heard.

declare in own responsibility that the products
described in this owner’s manual are in compliance
with technical standards:
EN 55013:2001
EN 55020:2002
Initially set the crossover frequency
control midway. While listening to music,
adjust the crossover for the least
perceived distortion from the speakers,
allowing them to reproduce as much
bass as possible.
• Maximum sensitivity: 260mV

CS50.4
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, indicating
the amplifier is on. If not, check the wiring,
especially the remote connection from the
source unit. Also refer to “Troubleshooting”
guide below.
• 67W RMS x 4 channels at 4 ohms and ≤1% THD + N
• Signal-to-noise ratio: 86dBA (reference 1W into 4 ohms)
• 82W RMS x 4 channels at 2 ohms, 14.4V supply and ≤1% THD + N
• 162W RMS x 2 channels at 4 ohms, 14.4V supply and ≤1% THD + N
• Dynamic power: 145W at 2 ohms
