built for the toughest tours and high-profile installations,

Precision series remote control amplifiers deliver superb

concert sound in a rugged package that stands up to the

rigors of the road. High-power Class-Ab designs drive

your boxes as hard as you need to get full, clear coverage.

Ultra-low distortion keeps your sound clean even at

peak volumes with heavy loads. And road-ready design

features—dual power supplies, multiple fans and complete

electronic protection circuitry—keep the show going while

safeguarding both your investment and your reputation.

Long a staple of top touring companies, Precision series

amplifiers are better than ever with the inclusion of the

RCM-24 module, which brings Precision series amps under

IRIS-Net control with state-of-the-art DSP technology.

offering system supervision, signal routing, IIR filters,

level control and dynamics, Precision series remote control

amplifiers set the standard for professional concert sound.
