The QSC Rear Rack Ear Kit 3IN is a rear-support mounting accessory for QSC rack-mounted power amplifiers. It is not an amplifier; it consists of a pair of 3-inch L-brackets and hardware that brace the rear of the amplifier against the rear rack rail so heavy chassis are not supported by the front ears alone.
Key Features
- Two 3-inch rear-support L-brackets plus mounting screws
- Adds rear bracing to reduce stress on front rack rails
- Ideal for touring, rental and mobile amplifier racks
- Suited to shallower rack depths than the 7-inch kit
- Straightforward bolt-on installation
Rear support helps protect amplifiers from the vibration and shock of transport. The 3-inch version is the shorter-reach option, appropriate when the distance to the rear rail is smaller or when a compact bracket is preferred.
