2.0 Setup 2.1 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.

Figure 2.2.3 Rack Mounting the Mixer-Amplifier To install, refer to Figure 2.2.3 and follow the steps below: 1. Attach the front angle brackets to each side of the front of the amplifier using the screws provided. 2. Attach the rear flat brackets to each side of the rear of the amplifier with the screws provided. 3. Install the unit into the cabinet using the rack mount screws through the front angle brackets.
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. The back of the rack should be open. 2.
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.
2.6 Wiring Your Audio System WARNING - TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE. AVERTISSEMENT - RISQUE DE CHOC ÉLECTRIQUE - NE PAS OUVRIR. AVERTISSEMENT - ÉNERGIE ÉLECTRIQUE DANGEREUSE VOIR LA NOTICE DE FONCTIONNEMENT.
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. WARNING: The third prong of this connector (ground) is an important safety feature.
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.
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. For example, if you set switch 1 to ON, Input 1 will be routed to both AMP1 and AMP2. 3.
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. Adjusting in the counterclockwise direction will reduce that level while the full clockwise setting will disable the VOX function. 3.
3.7 Media Player 3.7.1 Bluetooth Operation To activate Bluetooth, perform the following: 1. Press the Bluetooth Key until the Bluetooth Indicator begins to flash. 2. Enable Bluetooth of your source media player and search for “JBL COMMERCIAL (XX)”. Establish a connection. (Note that the “XX” represents the last two digits of the MAC address which allows the user to have multiple systems in close proximity.) 3. Once connected, the Bluetooth Indicator will stop flashing and remain illuminated. 4.
• REPEAT ALL 60Min Message – Play the track with the predefined name, “MESSAGE_1.mp3” every 60 minutes while repeating all other tracks. • REPEAT OFF – No repeat. 5. Press the PLAY/PAUSE key to pause or resume playing. 6. Press the STOP key to stop playing. 7. Press the PREVIOUS Key once to jump to the beginning of the current track or twice to the previous track. 8. Hold down the PREVIOUS Key to rewind. 9. Press the NEXT Key to jump to the beginning of the next track. 10.
4.0 Troubleshooting CONDITION: No power to the mixer-amplifier so that the power LED is not illuminated. POSSIBLE REASON: The mixer-amplifier is not plugged into the power outlet. 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: Mixer channel inputs are turned down.
