Description

e LRS 4 provides a simple interface to end users requiring
four predetermined volume levels (may include mute) when used
in conjunction with devices equipped with voltage-controlled
level inputs. Compatible Rane units include the CP 64, CP 52,
DA 26, or MP 44. Units with the Versatile Input Port (VIP)
are also compatible, including the Drag Net family of RPM
products.

ground) and outputs a single voltage (VC) that is varied depend­ing on the selected LRS 4 button. us, four volume levels can
be setup during installation. Any button may be set to any gain
between unity and mute. Typically, 4 is set for the highest gain
with 3, 2, 1 graduating down to mute, if available.

e LRS 4 remote assembly mounts in a standard U.S.
electrical box with a minimum depth of 2.5" [6.4 cm]. Turn
the power to the unit off until all connections are made. It is
important to ensure that the Remote Ports are not subjected to
sustained voltages outside the range of 0 to 5 volts DC or high
levels of static. e device inputs are protected, however you can
save a lot of time by taking this precaution. It is a good idea to
install the wiring, connect it to the Remote and then make the
final connections at the unit.

When wiring to Euroblocks, a minimum wire gauge of 22
is preferred for reliability. If the ground or shield wire is left
shorter, it acts as a strain relief for the other wires. Cable with a
flexible jacket is easier to use and less likely to damage the con­nections. Be sure to note the wire color of each input in order
to facilitate correct wiring to the unit. Make sure wires are free
of nicks and that the cable jacket is stripped back sufficiently
to allow it to lie in the electrical box with the remote assembly
inserted. Connect each wire to the 5-pin connector by fully
inserting it in the correct socket and tightening the screw.

Use the flat head #6 screws supplied with the kit to mount
the remote assembly and silkscreened front panel to the electrical
box. Install the Decora plate of your choice (not included).

Wire Types

Variations in wire type do not greatly affect the performance
of the remote controls. However, 22-gauge stranded wire with
a flexible jacket is recommended. You may use 3-conductor
unshielded remote control signal cable for shorter runs (less than
200 feet [60 meters]) or 2-conductor (1 pair) shielded remote
control signal cable (use the shield as the GND return) for longer
runs (200 to 1000 feet [60 to 300 meters]). e type of wire
required is influenced by your installation and local electrical
codes.

Rane Corporation does not provide or source cable. Please
