13
2.3 Ensuring Proper Cooling
When using an equipment rack, keep a minimum space of 4 inches (10cm) from the
top surface of the unit. Close any open spaces in the rack with blank panels. DO
NOT block any air vents. The side walls of the rack should be a minimum of 2 inches
(5 cm) from the amplifier sides. The back of the rack should be open.
2.4 Choosing Input Wire and Connectors
We recommend using prebuilt or professionally wired balanced line (two-conductor
plus shield) 22-24 gauge cables to connect the amplifier balanced input by using the
included Euro-block connectors, see Figure 2.4. Unbalanced lines may be used, but
may result in hum or RF noise very long cable runs.
You can also use RCA connectors to connect audio devices, for example, CD/DVD
player. However, do not use both Euro-block and RCA audio input connectors on a
single channel at the same time.
NOTE: Custom wiring should only be performed by qualified personnel.

2.5 Output Wiring and Connectors
To drive distributed speaker systems designed to operate at 70V or 100V, connect to
the corresponding output terminals.
JBL recommends using prebuilt or professionally wired, high-quality, two-conductor,
heavy gauge speaker wire. Speakers wires should be twisted cable, if possible. To
prevent the possibility of short-circuits, the wires should be stripped back no greater
than 6 mm (1/4 inch), see Figure 2.5.
Suggested below are guidelines to select the appropriate size of wire based on the
distance from amplifier to speaker. Check with local code as this may vary.

2.6 Wiring Your Audio System
Typical input and output wirings are shown in Figure 2.6.
INPUTS: Connect input wiring for both channels using either the RCA or the Euroblock input for each channel.
OUTPUTS: You may use either low impedance or high impedance speakers.
Always be sure to maintain the proper polarity when wiring speakers.
Low Impedance Speakers should be driven using the +/- pins of the amplifier output
connector. The minimum impedance an amplifier channel can drive is 4 Ohms.
Therefore, you can connect up to four 16 Ohm speakers, two 8 Ohm speakers or one
4 Ohm speaker to an amplifier output channel.
High Impedance Speakers should be driven using the appropriate (70V or 100V) pin
to speaker (+) and the COM pin to speaker (-) of the amplifier output connector. The
minimum impedance that can be driven from each output is provided in Appendix
A. Note that the HI-Z switch must be ON in order to provide audio to the high
impedance outputs.
WARNING: Do not connect to both low impedance speakers and high impedance
speakers from the same audio output channel.
16
2.7 Connecting to AC Mains
Connect your amplifier to the AC mains power source (power outlet) with the
supplied AC power cord. First, connect the IEC end of the cord set to the IEC
connector on the amplifier; then, plug the other end of the cord set to the AC mains.
When properly connected to a live power source, the power ring should illuminate
with a green color.
WARNING: The third prong of this connector (ground) is an important safety feature.
Do not attempt to disable this ground connection by using an adapter or other
methods.
Amplifiers don’t create energy. The AC mains voltage and current must be sufficient
to deliver the power you expect. You must operate your amplifier from an AC mains
power source with not more than a 10% variation above or below the specified line
voltage and within the specified frequency range indicated on the back panel of the
amplifier. If you are unsure of the output voltage of your AC mains, please consult
your electrician.
2.8 Protecting Your Speakers
It’s wise to avoid clipping the amplifier signal. Not only does clipping sound bad, but
it can damage high-frequency drivers. The built-in clip limiter prevents clipping.
Also, avoid sending strong subsonic signals to the amplifier. High-level, lowfrequency signals from breath pops or dropped microphones can blow out drivers.
You can switch to the HI-Z mode which, in addition to switching in the output
transformers for 70V and 100V speakers, activates the high-pass filter. The filter
prevents potentially damaging subsonic signals from going to the amplifier by
eliminating signals below 70Hz.
2.9 Startup Procedure
Use the following procedure when first turning on your amplifier:
1. Turn down the level of your audio source.
2. Turn down the level controls of the amplifier.
3. Power up the amplifier. The Power ring should change from green to blue.
4. Turn up the level of your audio source to an optimum level.
5. Turn up the Level controls on the amplifier until the desired loudness or power
level is achieved.
If you ever need to make any wiring or installation changes, don’t forget to
disconnect the power cord.
17
3.0 Operation
3.1 Precautions
Your amplifier is protected from internal and external faults, but you should still take
the following precautions for optimum performance and safety:
1. Before use, your amplifier first must be configured for proper operation,
including input and output wiring hookup. Improper wiring can result in serious
operating difficulties.
For information on wiring and configuration, please consult the Setup section of
this manual.
2. Use care when making connections, selecting signal sources and controlling the
output level.
3. Always be sure to have all levels at minimum when connecting or disconnecting
audio sources from the inputs. Failure to do so may cause the amplifier or
speaker to go into a protection mode or even cause damage.
4. WARNING: Never connect the output to a power supply, battery or power main.
Electrical shock may result.
5. Tampering with the circuitry, or making unauthorized circuit changes may be
hazardous and invalidates all agency listings.
6. Do not operate the amplifier with the red Clip LEDs constantly flashing.
7. Do not overdrive the mixer, which will cause clipped signal to be sent to
the amplifier. Such signals will be reproduced with extreme accuracy, and
loudspeaker damage may result.
8. Do not operate the amplifier with less than the rated load impedance. Due to
the amplifier’s output protection, such a configuration may result in premature
clipping and speaker damage.
9. Use the amplifier in a well-ventilated environment and do not use it in ambient
temperature conditions in excess of 40°C. Failure to do so will result in the auto
disconnection from power supply, and the overheat auto protection function will
be activated. The power indicator will become green and there will not be any
audio signal coming out of the amplifier. In this case, turn down the volume to
the minimum, and the amplifier will soon resume working. When the amplifier
returns to normal temperature the power indicator will return to blue and you
may turn the volume up to a safe level.
10. If the line voltage to the amplifier is too low, the low voltage protection function
will be activated. The power light ring will change from blue to green.
CAUTION: JBL is not liable for damage that results from overdriving other
system components.
18
3.2 Hi-Z Switch
When this switch is in the “OFF” position, the amplifier is configured to drive low
impedance speakers, (4 Ohms ,minimum) The Hi-Z switch will switch in the built-in
output transformer allowing the unit to drive 70V or 100V speaker systems directly
when connected to the appropriate output terminals. As an added feature when
driving the high impedance speakers, the system automatically switches in a 70Hz
high pass filter.
3.3 Remote Volume Control
Remote volume control can be implemented using a CSR-V controller connected via
an Ethernet cable to the RJ45 connector on the back panel. For the CSA 240Z,
CSA 280Z and CSA 2120Z, there are two connectors, one for each amplifier output.
3.4 Sleep Mode
To save energy, the unit is designed to go into sleep mode after approximately 2
hours operating with no signal at any of the inputs. Return of signal (-36dBu) to
any input will wake the unit from its slumber. The sleep mode can be disabled by
activating the Sleep Disable switch on the rear panel.
19
4.0 Troubleshooting
CONDITION: No power to the amplifier so that the power ring is not illuminated.
POSSIBLE REASON: The amplifier is not plugged into the power receptacle
CONDITION: No sound or low sound.
POSSIBLE REASON: The input signal is not present or at a very low level.
POSSIBLE REASON: The Master Volume control is turned down.
POSSIBLE REASON: A CSR-V is connected and turned down.
POSSIBLE REASON: The Hi-Z switch is OFF while using the 70V or 100V outputs.
POSSIBLE REASON: The power switch is OFF. (Note that while plugged in, the
amplifier will be in standby mode and the power ring will be
green until the power switch is activated
and the power ring will turn blue.)
CONDITION: Distorted sound.
POSSIBLE REASON: Input signal level is too high. Please turn down the input level
controls. Note that theamplifier should not be operated at a
level that allows the clip indicator to be constantly ON.
POSSIBLE REASON: Master Volume is too high.
