Setup

Unpacking Your Amplifier
Please unpack and inspect your amplifier for any damage that may have occurred during transit. If damage is found, notify the transportation company immediately. Only you can initiate a claim for shipping damage. We will be happy to help as needed. Save the shipping carton as evidence of damage for the shipper’s inspection. We also recommend that you save all packing materials so you will have them if you ever need to transport the unit. Never ship the unit without the factory pack.
WARNING: Before you start to set up your amplifier, make sure you read and observe the Important Safety Instructions found at the beginning of this manual.

Installing Your Amplifier
CAUTION: Before you begin, make sure your amplifier is disconnected from the power source and all level controls are turned completely down (counterclockwise). To install the amplifier, you can use one of the following approaches:

  •  Rack mount the amplifier with the rack mounting kit, see Figure 2.2.2.
  •  Place a single amplifier on a surface with 12 inches of air space around the unit for convection cooling. Rubber feet are included and can be attached to the underside of the chassis. For amplifier dimensions, see Figure 2.2.1.

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.

 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 for very long cable runs. You can also use RCA connectors to connect audio devices, for example, CD/DVD players. 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. Figure 2.4 Input Wiring

Note: Two RCA connectors are provided for summing left and right channels from a stereo source. Do not use both Euro-block and RCA connectors concurrently for any single input channel.

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. Speaker 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 the amplifier to the speaker. Check with the local code as this may vary.

  • Distance Wire Size
  • Up to 25 ft. (7.6m) 16AWG
  • 26-40 ft. (7.9-12.2m) 14AWG

Professional audio system

 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 Euro-block 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 wired in parallel, two 8 Ohm speakers wired in parallel or one 4 Ohm speaker to an amplifier output channel. High Impedance Speakers should be driven using the appropriate (70V or 100V) pin to the speaker (+) and the COM pin to the 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.

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 and switched on, the power ring should illuminate with a blue 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.

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, low-frequency 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.

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 will illuminate 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.

Operation

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 a 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 the 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 activate the thermal limiting function, compressing the audio at the output amplifier and the Signal Presence Indicator will light red.

CAUTION: JBL is not liable for damage that results from overdriving other system components.

 70/100V 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.

Remote Control Capability
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 2300Z, there are two connectors, one for each amplifier output. Additional features are remotely accessible through the RJ45 port using serial control. (For the CSA 2300Z, where there are two RJ45 connectors, the serial control feature is accessible via the Channel 1 connector only.) Please see Appendix B for more details regarding remote operation using RS232.

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: RS232 control has placed the unit into sleep mode. (Power light ring will be green)
  • POSSIBLE REASON: The Hi-Z switch is OFF while using the 70V or 100V outputs. POSSIBLE REASON: The power switch is OFF.
  • CONDITION: Distorted sound.
  • POSSIBLE REASON: The input signal level is too high. Please turn down the input level controls. Note that the amplifier should not be operated at a level that allows the clip indicator to be constantly ON.
