Federal Signal High Powered Public Address Amplifiers

The new Federal Signal AudioMaster® Amplifiers are available in four different power ratings from 300 to 2400 watts per channel, and can be independently configured to drive either step-down transformers in a distributed “constant-voltage” loudspeaker system (70-volt or 100-volt mode) or a system of loudspeakers that do not require step-down transformers (8/4 ohm mode).
