QSC Audio SA 1350 user manual Rack Mounting, Cooling, AC Mains, Setting the Mode Switches

Rack Mounting

Use four screws and washers to mount the amplifier to the equipment rack rails. To use the amplifier outside a rack, attach the self-adhe- sive rubber feet to the bottom.

EN

Cooling

Air flows from the rack, into the back of the amplifier, and out the front. This keeps the rack cool. The fan automatically runs faster when the amp is working hard.

Do not block the rear intake or front air vents!

AC Mains

Connect AC power to the IEC socket on the back of the ampli- fier. NOTE: Turn off the AC power switch before connecting AC power.

The correct AC line voltage is shown on the serial number label, on the rear panel. Connecting to the wrong line voltage may damage the amplifier or increase the risk of electric shock.

Setting the Mode Switches

The rear panel mode switches control the amplifier’s operating mode, and each channel’s independent clip limiting and low fre- quency (LF) filtering. All models Clip Limiter switch settings are the same. However, Operating Mode and Low Frequency Filter settings are different for the Ti models. The rear panel label shows this information for convenient reference.

Air flow in QSC amplifiers: Cool air is drawn into the rear of the amplifier by the cooling fan. Warm air exits the front of the amplifier.

Setting Clip Limiters

Each channel has a clip limiter with its own on-off switch. The limiter only responds to actual clipping, and automatically com- pensates for load and voltage variations. Clip limiting is gener- ally recommended, especially to protect high frequency drivers.

Switch 1 controls CH1. Switch 10 controls CH2.

Set switch to RIGHT to use Clip Limiting.
