VOLUME REMOTE
Description
°e VR2 mounts in a standard US electrical box and can be
covered with a Decora plate. It contains a linear taper potentiom-
eter with a single Euroblock screw terminal for each of the pot’s
three conductors, the Vr terminal, the Vc wiper terminal, and the
ground terminal.
Connection
Turn the power to the unit off until all connections are made.
Con-
nect the VR2's
control voltage Vc (wiper) connection(s) first.
°en connect the voltage reference - “Vr” on the VR2 (“REF”
terminal on a RPM unit). Connect the GND (ground) terminal
last. Double and triple check your wiring before applying power
to the MA 4 or RPM since improper wiring can and will cause
permanent, irreparable damage to the VR2, requiring replace-
ment of the remote.
Such damage is not covered by Rane's war-
ranty
; checking the wiring is easier than a second trip to the job
site with another remote.
