Speco Technologies PBM-30 is a 30W commercial PA amplifier. It features an auto mute function, music on hold output with separate level control (600 ohm line and one watt 8 ohm) and 600 ohm telephone line input with level control. In addition to the telephone line input, this unit accepts inputs from two sound sources. Each source utilizes a microphone input (terminal strip). Source 1 also offers the option of an auto summing stereo auxiliary RCA input. Outputs include a choice of 4, 8, and 16 ohm as well as 70 and 25 volt line outputs.
Speco Technologies’ UL listed Contractor Series amplifiers are designed for long-running, every day use. They can stand on their own to run a smaller installation, or be incorporated into a much larger job. With RMS power ranging from 30W to 120W, microphone and source-mixing ability, telephone paging interface and music-on-hold capability, there’s practically no job where one of these amplifiers wouldn’t be a perfect fit!
