RDL DS-RLC10M – Remote Level Control with Muting, Stainless

What is the RDL DS-RLC10M?

The RDL DS-RLC10M is a rotary remote level control with pushbutton muting for RDL VCA modules and OEM equipment with 0 to 10 Vdc ramp inputs, finished in stainless steel. An optical encoder allows continuous knob rotation, and an LED ring display shows the operating level. One control can be the MASTER with up to nine more wired in parallel, giving as many as ten control locations.

How does it work?

The DS-RLC10M connects directly to any RDL VCA or OEM equipment that accepts a 0 to 10 Vdc ramp input. A single control can be wired to a ramp-controlled VCA using a single-pair shielded audio cable or unshielded cable. A rear-panel switch sets the control to MASTER, where it drives the ramp output and monitors its pulse terminals for additional controls. Up to nine additional controls set to SLAVE can be wired in parallel using UTP cable such as CAT5 or CAT6. Acceleration makes the level change faster when the knob is turned quickly, which helps when feedback must be pulled down fast. The LED ring works as a virtual pointer, staying bright during adjustment and dimming afterward to avoid distraction. A MUTE pushbutton with LED indicator is built in, and on power-up the control returns either to the last level or to a stored preset; holding MUTE for more than 3 seconds stores a new preset. Multiple SLAVE controls can also connect to an RDL RU-VCA2A or RU-VCA6A, using the VCA as the ramp generator. The control is built on a steel frame with a detachable rear terminal block and fits a standard US electrical box, an RDL WB-1U wall box or an RDL SMB-1W surface box, with a cover plate such as the RDL CP-1S sold separately.

What are the key features?

• Optical rotary encoder — Continuous knob rotation gives long-term, noise-free level adjustment.
• Up to ten locations — One MASTER plus up to nine SLAVE controls wired in parallel over UTP cable.
• Integral 0 to 10 Vdc ramp — In MASTER mode the control generates the ramp voltage for the VCA.
• LED ring level display — The display is bright during adjustment and dims afterward.
• Pushbutton muting with preset — A MUTE button with LED, plus power-up to the last level or a stored preset level.
• Works with all RDL VCA modules — Also compatible with OEM equipment that accepts 0 to 10 Vdc ramp control.

Where is it typically used?
