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). Space is provided next to each button for labeling.
The LRS 4 accepts a two-wire DC voltage input (V+ and ground) and outputs a single voltage (Vout) that is varied depending on the selected LRS 4 button. Thus, four volume levels can be setup during installation: selecting the top button provides the maximum or highest output voltage (~V+) typically the highest volume. Select the second and third buttons for two different installer-programmable lower volumes. The bottom button grounds the output pin thus providing the lowest voltage output typically the muted condition.
Consult the Operators Manual of the connected Rane equipment for details on functions. The LRS 4 works with any of these products:
"How do I mount Rane Decora remotes in a rack?"
We recommend Lowell rack panels.
The LRS 4 fits in a standard U.S. electrical box with a minimum depth of 2-1/4 inches, and flush covered with a standard Decora plate cover (not included).
Note: Older Rane units may be marked differently. Consult this chart if your unit does not have VR and VC terminals.
