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.  
Set crossovers according to application.

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)
