LRS 4 Level Recall Remote

The LRS4 has been discontinued

The 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. The LRS 4 contains four radio buttons: engaging one button (in, changing to green) causes any of the other three to disengage (out, changing to black).

The LRS 4 accepts a two-wire DC voltage input (VREF and ground) and outputs a single voltage (VC) that is varied depending on the selected LRS4 button. Thus, 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.

The LRS 4 fits in a standard US electrical box and can be paired with a Decora™ plate for improved architectural beauty. It is compatible with these units:

Remote Mounting and Wiring

The 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. The 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.

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]). The type of wire required is influenced by your installation and local electrical codes. Please contact your local retail or wholesale outlet, not the Rane factory. The following is a short list of suitable cable types:

Plenum cable:
Unshielded remote control signal cable CAT. #9896
Shielded remote control signal cable CAT. #9877 or #9852

Communication and control cable:
Multiconductor, unshielded CAT. #7606

Communication and control cable:
Multiconductor, unshielded CAT. #1175C

Unshielded remote control signal cable CAT. #88741
Shielded remote control signal cable CAT. #88723
