The WR-5 is microprocessor based remote control unit for most Ashly NE products. Compatible products currently include Pema amplifiers, ne8800 and ne4800 system processors, ne24.24M matrix processor and all models of the NE multichannel (four or eight channel) power amplifiers. Additional products may become available in the future. Using Protea NE software, six function select buttons and two parameter adjust buttons are available to control a limited range of assigned functions within their host product. Up to four WR-5 units can be daisy-chained and phantom powered from one NE product, and even more can be added using an in-line power supply adapter such as the Ashly RPS-18. If a WR-5 is used with NE host product, no other serial communications devices, including the Ashly RD-8C, may be used with that product.
