Use this output to connect signal to a secondary amplifier. 6. Zone 2 Level Control Potentiometer adjusts level for both Zone 2 outputs. 7. Zone 2 Output Terminals 4-terminal Euroblock connector (2 terminals for 1W output to 81 loudspeaker, 2 terminals for 6001 output to PBX MOH, music-on-hold, port or an additional amplifier). 8.
AA35G & AA60G Owner’s Manual Commercial Mixer Amplifier Choose Input Wire and Connectors AtlasIED recommends using balanced line (two-conductor plus shield), 22-24 gauge cables and connectors. Unbalanced line may also be used but may result in noise over long cable runs. The AA35G and AA60G have two types of input connectors: Euroblock and RCA. • Mic / Line Connector (CH1): 5-pin Euroblock, balanced, pins 3, 4 and 5 (Figure 2.3).
AA35G & AA60G Owner’s Manual Commercial Mixer Amplifier Choose Output Wire and Connectors Amplifier Output Connections: Slip the cable lugs under the output screw terminals and tighten (Figure 2.5). Slide the supplied non-touch cover over the output connections from top to bottom to cover them. AtlasIED recommends using high-quality, two-conductor, heavy gauge speaker wire and connectors. Crimp-on spade lugs may be used for the output connectors.
AA35G & AA60G Owner’s Manual Commercial Mixer Amplifier Wire the System Typical input and output wiring is shown in Figure 2.8. INPUTS: For Input 1, connect a microphone or balanced line-level signal to the Input 1 balanced input. Set the Mic/Line switch (DIP switch #1) accordingly. For the other inputs, connect unbalanced line-level signals to the RCA input connectors. OUTPUTS: Maintain proper polarity (+/–) on amplifier output connectors.
AA35G & AA60G Owner’s Manual Commercial Mixer Amplifier Operation Powering Up 1. Turn Off any equipment connected to the Preamp Output connector. 2. Plug the amplifier’s power cord into a 3-wire grounded AC outlet. 3. Turn down the input volume controls. 4. Turn down the master volume control. 5. Turn on the Power switch. The Power indicator should glow. 6. Turn the input volume controls in use about 3/4 up. 7. Turn up the master volume control(s) until the desired loudness or power level is achieved. 8.
AA35G & AA60G Owner’s Manual Commercial Mixer Amplifier Troubleshooting CONDITION: No power to the mixer amplifier. POSSIBLE REASON: • The mixer amplifier’s power switch is Off. • The mixer amplifier is not plugged into the AC power receptacle. • The mixer amplifier’s high-voltage power supply circuit breaker has tripped. Verify that the AC mains voltage is correct. CONDITION: Distorted sound. POSSIBLE REASON: • Input signal level is too high. Turn down the input level controls.
