Figure 2.2.3 Rack Mounting Two Units To install two units in your cabinet system, refer to Figure 2.2.3 and follow the steps below: Align two modules side by side and upside down with the front panel towards the same direction. Connect them with the flat bracket using the screws provided.

Figure 2.2.4 Rack Mounting A Single Unit To install a single unit, refer to Figure 2.2.4 and follow the steps below: Determine which side of the rack opening will be used for the amplifier and attach the long angle bracket to the other side at the front of the amplifier using the screws provided.
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.
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.
Figure 2.6 Wiring Audio System Professional audio system CSR-V LEVEL 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 Euro- block input for each channel. OUTPUTS: You may use either low impedance or high impedance speakers.
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.
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.
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.
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.
