USER MANUAL SPA460 QSC

The term “WARNING!” indicates instructions regarding personal safety. If the instructions are not followed the result may be bodily injury or death. The term “CAUTION!” indicates instructions regarding possible damage to physical equipment. If these instructions are not followed, it may result in damage to the equipment that may not be covered under the warranty. The term “IMPORTANT!” indicates instructions or information that are vital to the successful completion of the procedure. The term "NOTE" is used to indicate additional useful information. The intent of the lightning flash with arrowhead symbol in a triangle is to alert the user to the presence of un-insulated "dangerous" voltage within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans. The intent of the exclamation point within an equilateral triangle is to alert the user to the presence of important safety, and operating and maintenance instructions in this manual.

• Minimum open space of 6 inches measured from back of amplifier. NOTE: QSC System Power Amplifiers contain advanced protection circuitry which allows them to reduce output power in order to maintain safe operating temperatures. Insufficient ventilation may result in the amplifier reducing output power during normal operation (indicated by Limiter/Protect LEDs illuminating red). To reduce the possibility of thermal limiting, and allow proper heat dissipation, we recommend that you keep the space directly above and to the rear of these amplifiers free of obstacles. — Figure 1 —

Remote Figure 30 – Figure 32 SPA 2-channel (1) 3.5mm, 5-pin SPA 4-channel (1) 3.5mm, 10-pin When the potentiometer is at the minimum position, the amplifier goes into Mute mode. On the SPA 4-channel amplifier, the remote level controls for channel 1 & 2 are independent from channels 3 & 4 remote level control. On the SPA 4-channel model, closing the "Standby Switch" between the first two pins of either Ch1-Ch2 or Ch3-Ch4 causes all four channels to go into Standby. — Figure 30 — 10 kΩ Standby Switch in Run Mode Standby Switch in Standby Mode V = +10Vdc reference outputC = 0-10Vdc control inputC @ 10V = Max VolumeC @ 0V = Mute — Figure 31 — — Figure 32 — SPA 4-channel SPA 2-channel11 TD-000500-00-D
