The D SERIES-RLC10 is a rotary remote level control that provides user adjustment at single or multiple locations. Optical encoder technology allows continuous knob rotation with a comfortable adjustment rate and long-term trouble-free and noise-free operation. These controls directly connect to any RDL VCA and OEM equipment with 0 to 10 Vdc ramp inputs.

A single –RLC10 may be connected to a ramp-controlled VCA using a single-pair shielded audio cable or unshielded cable. A rear-panel switch configures the control as the MASTER. The MASTER mode causes this control to drive the 0 to 10 Vdc ramp output and to monitor its pulse terminals in case any other –RLC10 controls are connected.

As many as nine additional –RLC10 controls may be wired in parallel with the MASTER control using UTP cable (CAT5, CAT6 or equivalent). The rear-panel MODE switch on each additional remote control is set to SLAVE mode.

Operation is the same for a single control, or for each control connected in a multiple control point installation. The 0 to 10 Vdc ramp voltage is incremented up or down when the front-panel knob is rotated. Acceleration is provided so the rate of change is faster when the knob is rotated more rapidly, yielding a responsive feel and rapid elimination of acoustic feedback. The LED ring display encircling the control knob operates as a virtual pointer. When an –RLC10 is not being adjusted, its display switches to a dim intensity to avoid being a visual distraction. The display returns to a bright intensity during adjustment.

In the event of power loss, internal non-volatile memory stores the last level value. When power is restored, the 0 to 10 V output will return to the operating level present when power was lost.

Multiple –RLC10 controls set to the SLAVE MODE may be connected to an RDL RU-VCA2A or RU-VCA6A, utilizing the VCA as the ramp generator. This connection is also possible with OEM equipment accepting open-collector pulses that are compatible with the –RLC10 output pulse rate and width.

The –RLC10 controls are constructed on a steel frame. The electronics are fully protected within the rear enclosure. Connections are made through a rear panel detachable terminal block.

All the D SERIES-RLC10 features combine to make it the ideal choice for single point or multiple location remote level control in high quality systems. Use them with any RDL VCA module, or side-by-side with other RDL remote accessories as part of a complete audio/video system

D-SERIES

D Series products are user controls, indicators and connection plates that are compatible with Decora® style mounting. D Series modules and jacks connect directly to a variety of active RDL modules in multiple product series and are compatible with many OEM products. Products in this series may be active or passive. All D Series front panels are constructed of stainless or carbon steel for durability, shielding and static protection. Stainless steel models feature a brushed finish with direct lettering. Painted models are finished with a reverse-printed front-panel polycarbonate laminate which provides an attractive, durable finished appearance.

Connector plates offer pass-thru jacks or rear-panel solder terminals. Transformer-isolated connector modules are equipped with a shielded enclosure and a rear-panel terminal block.

Active models include remote controls to provide source selection, routing, level control, muting, source or level LED indication and more.

The depth of D Series products is sufficiently shallow to permit mounting not only in standard North American electrical boxes but also in RDL wall boxes designed to fit in narrow walls used in international installations. RDL also offers a variety of related accessories for wall mounting, surface mounting and desktop chassis mounting of D Series products, as well as matching metal trim plates.

Attractive styling, ease of installation, long-life pushbuttons, high quality connectors and worldwide mounting possibilities make D Series products a preferred long-term resource for system design solutions. D-SERIES modules are designed and manufactured in the U.S.A.
