ETL ListedThe Federal Signal line of high-powered audio amplifiers provides the flexibility, quality, and performance required in an industrial public address system. AudioMaster® amplifiers are available in four different power ratings from 1200 watts to 3000 watts. Each output channel can be independently configured to drive either the step-down transformers in a distributed "constant-voltage" loud-speaker system (70-volt mode) or a system of loudspeakers that do not require step-down transformers (8/4 ohm mode).

Additionally, the Models CTS2000 and CTS3000 can operate in 100-volt mode. The 70-volt and 100-volt outputs eliminate the need for step-up transformers, which can create distortion and cause insertion loss.The quality of AudioMaster amplifiers is apparent in the noise-free, crystal clear highs and lows they reproduce. The grounded bridge design of the CTS series provides for less distortion and thermal stress, and a simpler, more reliable power supply than found in typical stepped "linear" output systems.AudioMaster amplifiers consume significantly less power per watt than typical central amplifiers and reduce long term operating costs.

A unique soft-start circuit and a four second pseudo-random turn-on delay minimizes inrush currents and eliminates the need for power sequencers.When combined with the AudioMaster AudioRouter and the complete line of AudioMaster Speakers, these high-powered amplifiers are a key component in a high performance, industrial public address system.
