581 Distribution Amplifier (4×4)

The Symetrix 581E Distribution Amplifier (4×4) is a four-input, sixteen-output distribution amplifier. In a typical configuration the 581E accepts four balanced input signals and distributes each input to four independent outputs. The volume of each of the sixteen outputs may be individually trimmed via its front panel potentiometer. Similarly, the volume of each of the […]

572 SPL Computer

The Symetrix 571 is an ambient noise sensing automatic level controller or SPL computer. The 571 uses one or two sensing microphones, located in the coverage zone of the sound system,to continuously sample the loudness of ambient sounds. The 571’s microprocessor, running proprietary embedded software, computes how loud the soundsystem should be, based on the […]
