4. PEMA REMOTE CONTROL
The following hardware devices are currently available for remote control of Pema amplifier 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 amplifier 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 fit in a stan-
dard wall electrical box, and is wired to the amplifier back panel Euroblock connector labeled “Remote Level Control” using
four conductor wire. If wiring a custom potentiometer assembly other than the WR-1, c5V 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.
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
amplifier. The terminal numbers correspond to the first 4 Preset
Memory locations in the controlled amplifier. 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 amplifier 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 amplifier. Up to four different WR-5
remotes can be wired in series and phantom powered from a
Pema amplifier, and more can be added by using an Ashly RPS-
18 remote power supply.
