4. PEMA REMOTE CONTROL

The following 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 controlled 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 Level Control
is a dual potentiometer remote volume control
designed to fit in a standard 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 potenti-
ometer 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.
4.1b WR-1.5 Level Control and Preset
Recall Switch
- The WR-1.5 has a four position
rotary switch for selection of stored amplifier presets
1-4, and a potentiometer for remote DC level control
of one amplifier channel. Clear windows are provided
for user generated labels.
4.1c WR-2 Preset Recall Switches
WR-2 allows selection of one of four presets via inter-
locking pushbutton 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.
4.1d WR-5 Programmable Button Controller
- 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.
WR-5 buttons are programmed from Protea
after the WR-5 is wired to a Pema amplifier and assigned a
unique ID number in its WR-5 device window. Each button has a status LED. Controlled functions include preset recall/scroll,
mute, zone source selection, individual channel and matrix point level control. A windowed mylar pocket is available to insert
custom function button labels.
The Ashly RPS-18 remote power supply is required when more than four WR-5 remotes are connected to one Pema
amplifier.
