EXPLANATION OF SYMBOLS

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.

Ventilation

• Recommend 1RU (1.75 in / 44.45 mm) space above the amplifier.

• Minimum open space of 6 inches measured from back of amplifier.

NOTE:

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.

QSC System Power Amplifiers contain advanced protection

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.
