Rane MRS 4 User manual

DATA SHEET / MANUAL MRS 4
MEMORY RECALL SWITCH
Description
e MRS 4 provides a simple solution to recalling Memories
from a remote location for products having an MRP (Memory
Recall Port) or a VIP (Versatile Input Port).
e MRS 4 is intended for use in Normal mode, allowing
up to four Memories to be recalled by contact closure. ese are
radio buttons: engaging one button (in, changing to green) causes
any of the other three to disengage (out, changing to black). Space
is provided next to each button for labelling. Consult the Opera-
tors Manual of the connected Rane equipment for details on
Memory recall functions.

Remote Mounting and Wiring
e MRS 4 remote assembly mounts in a standard U.S. electrical
box with a minimum depth of 2.5".
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. Inputs are protected, however caution
is the better part of...you know. It is a good idea to install the
wiring, connect it to the Remote and then make the final con-
nections 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 con-
nections. 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
You may use 5-conductor unshielded remote control signal cable
for shorter runs (less than 200 ft.) or 4-conductor (2 pair) shield-
ed remote control signal cable (use the shield as the GND return)
for longer runs (200 to 1000 ft.). e type of wire required is
influenced by your installation and local electrical codes.Varia-
tions in wire type do not greatly affect the performance of the
remote controls. Rane Corporation does not provide or source
cable. Please contact your local retail or wholesale outlet, not the
factory.
