4. PEMA REMOTE CONTROL

The following hardware devices are currently available for remote control of Pema amplifi er functions. Some devices
control only one function, while others can control several different functions. Some remote control functions are also con-
trolled by software. A complete listing of all Pema amplifi er functions which can be remotely controlled, along with a listing
of respective control devices for each function, is found following the hardware descriptions listed here:

4.1 Remote Control Devices

4.1a WR-1 Remote Level Control - The WR-1 is a dual potentiometer remote volume control designed to fi t in a stan-
dard wall electrical box, and is wired to the amplifi er back panel Euroblock connector labeled "Remote Level Control" using
four conductor wire. If wiring a custom potentiometer assembly other than the WR-1, connect +5V from the Remote Level
Control Euroblock connector to the potentiometer's CW pin, GND to the CCW pin, and the channel under control to the wiper.
Do not connect the WR-1 remote level control ground to any other external grounds.
WR-1 Assembly
4.1b WR-2 Remote Preset Recall Switches - The WR-2
allows selection of one of four presets via interlocking push-
button switches. Each pushbutton switch can be connected to
a Preset Recall Pin on the back panel of the controlled Pema
amplifi er. The terminal numbers correspond to the fi rst 4 Preset
Memory locations in the controlled amplifi er. Pressing a button
will select the corresponding preset. Windows are provided for
a user-generated label.
4.1c WR-5 Programmable Remote Control - See illus-
tration on next page. The WR-5 is a programmable button remote
control which mounts into a standard North America electrical
wall box and connects to a Pema amplifi er data port using four
conductor wire. Maximum cable length is 1000 ft using #24
gauge twisted pair. A decora cover plate (not included) can be
purchased at hardware stores to cover the WR-5 electrical box
and satisfy the aesthetic needs of the installation. The WR-5 is
phantom powered from the amplifi er. Up to four different WR-5
remotes can be wired in series and phantom powered from a
Pema amplifi er, and more can be added by using an Ashly RPS-
18 remote power supply.
