SETUP- Rack Mounting
Supporting the Rear of the Amplifier
For mobile and touring use, it is extremely important to support the rear of the amplifier. The chassis and rack
can be damaged if the amplifier is not properly supported. Unless the amplifier is being installed in its final,
fixed location, QSC strongly recommends supporting the rear of the amplifier. Rear rack ears, required hard-
ware, and a separate instruction sheet are included with your amplifier. The Specifications section includes
helpful dimensions for determining rear support locations.
Method 2
The amplifier is first installed from
the front of the rack and secured to
the front rack rails. Temporarily
secure the rear ears to the rear rack
rails and select the appropriate
mounting position for the “pin”.
Remove the rear ears and install the
locator pins securely. Use of thread-
locking is recommended for high-
vibration installations.
Attaching Rear Rack Ears
Method 1
The amplifier is first installed from
the front of the rack and secured to
the front rack rails. The rear ears are
then secured to the amplifier using
two machine screws. The ears are
secured to the rails using regular
rack hardware.
