RS-232 Serial Control

The s80 amplifier contains a serial control input which allows your entire Opus 21 family to be operated from an automated controller. The RS-232 port operates in listen-only mode and is opto-coupled to prevent ground loops. Programming commands and configuration details are available on our web site.

Thermal Protection

Due to the high-efficiency design of the s80, overheating is unlikely. Should the thermal protection be triggered, the amplifier will mute the outputs. The display will indicate the internal temperature. Once the amplifier has cooled sufficiently, the display will return to normal and the amplifier can then be un-muted.
