The PL-8 is part of the Allen & Heath PL Series of wall plates and remote controllers available for the iDR-4 and iDR-8 audio mix processor systems. It is a small module comprising two circuit cards. This can be locally mounted in a single unit wall box using the standard UK, EU or US face plate supplied. The PL-8 provides four contact closure switch inputs and four transistor logic outputs for external equipment control. Their function is programmed using the iDR System Manager software. The combination of switch input and logic output makes the PL-8 ideal as a multi-function remote controller in installed systems. The unit can interface to a variety of devices including alarm systems, room divider switching, paging controls, event triggers and various custom switches and indicators. Control can be distributed where it is needed. The PL-8 interfaces via the Allen & Heath PL-Anet serial network. Multiple PL-8 units can be daisy-chained using CAT5 cable along with other PL-Anet devices such as the PL-3 and PL-4 wall plates, PL-6 fader controller and so on.
