APPLICATION: The D-SERIES-RC4ST is part of the RDL accessories group and is designed as a functional and
visual complement to many other RDL remote controls such as the D-RLC2, D-RLC3 or D-RLC10K Remote Level
Controls.
The -RC4ST is a wall-box mounted remote module designed to directly control a RDL ST-SX4 Audio Selector Switch
Module. The ST-SX4 provides solid-state switching of one of four unbalanced audio inputs to a single unbalanced
audio output. The -RC4ST connects directly to the POWER and CTRL terminals of the ST-SX4 using either a
3-conductor cable or a single shielded pair.
The front panel of the -RC4ST features four pushbuttons with four associated LEDs. Upon initial application of
power, source 1 is selected. Touching any of the other three buttons de-selects source 1 and immediately selects the
source corresponding to the button pushed. An LED adjacent to each button indicates which source is selected. For
stereo installations, the SLAVE output from the ST-SX4 is used to drive the CTRL input of an additional ST-SX4.
In a typical installation, the -RC4ST is mounted adjacent to a RDL remote-level control such as the D-RLC2,
D-RLC3 or D-RLC10K. The -RC4ST selects the audio source and the remote-level control permits adjustment of the
level including turning the level fully off (Note: The D-RLC2, D-RLC3 or D-RLC10K work in conjunction with other
RDL VCA modules, sold separately).
The -RC4ST is constructed on a durable polycarbonate-faced, powder-coated steel panel. Electronics are housed in
a metal enclosure featuring a rear panel detachable terminal block for easy wiring. The attractive front panel
graphics and quality construction make the -RC4ST the ideal choice in any high quality and economical
wall-mounted remote control installation.
Wherever a 4-channel remote control is needed, the -RC4ST is the ideal choice. Use the -RC4ST individually with
an RDL control module, or combine it side-by-side with other RDL remote accessories as part of a complete
audio/video system.
