11. REMOTE CONTROL

Ashly makes three remote control options for the Protea 24.24M. All of them are designed to be installed in a

standard wall mount electrical box using a standard cover plate. The WR-1 and WR-2 are passive controls which can

adjust volume or select presets respectively, while the WR-5 (replaces WR-3 and WR-4) is an active control with user

defined function buttons and LED display.

11.1 WR-1 Volume Control

The WR-1 is an assignable, dual potentiometer remote vol-

ume control for the 24.24M. Each volume control is connected to

a terminal block on the WR-1 circuit board, which in turn must be

wired to the 24.24M back panel euroblock connector labeled "0 -

5 Volt Remote Level Control". Do not connect the WR-1 remote

level control ground to any other external grounds.

By connecting a volume control to a specific pin (1-8), that

pin can be selected in software under <Options - Define Remote

Level Controls> to control the level of any combination of inputs

or outputs. It is possible to simultaneously select the same input

or output channel to multiple remote level control pins. Note, how-

ever, that the resulting attenuation on that channel is cumulative,

meaning that channel’s gain is set by combining the value of all

remote level controls mapped to that channel.

In addition to using a WR-1 as the control device, the re-

mote level control feature can be used for relay activated muting

of selected channels, as in a fire alarm application (see sec. 12).

Note: Use Protea System Software version 6.1.4 or higher, and

24.24M program version 1.5 or higher to allow assignable re-

mote control.
