Figure 2.2.3 Rack Mounting the Mixer-Amplifier To install, refer to Figure 2.2.3 and follow the steps below: Attach the front angle brackets to each side of the front of the amplifier using the screws provided. Attach the rear flat brackets to each side of the rear of the amplifier with the screws provided.
2.3 Ensuring Proper Cooling When using an equipment rack, keep a minimum space of 4 inches (10 cm) 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.
2.5 Output Wiring & Connectors To drive distributed speaker systems designed to operate at 70V or 100V, connect to the corresponding output terminals. JBL recommends using pre-built 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 2.5.1.

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 LED should illuminate blue.
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: 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.
3.2 Input Routing The two-channel models, VMA260 and VMA2120, include a default routing of Input channels 1-3, Music 1 and the Bluetooth/USB source to amplifier 1. Input channels 4-6 and Music 2 are routed to amplifier 2. The user may take any input and have it routed to both outputs by selecting the appropriate switch.
3.4 VOX Function Voice activated ducking is available on input channel 2 of the VMA160, VMA1120 and VMA1240. The feature is available for both input channels 2 and 5 of the VMA260, and VMA2120. The audio input level required to activate ducking is set using the trim pot on the rear panel.
