The D SERIES-RLC10M is a rotary remote level control with pushbutton muting 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 –RLC10M 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 –RLC10M controls are connected.
As many as nine additional –RLC10M 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 –RLC10M 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.
Upon power-up or re-powering after a power loss, the 0 to 10 Vdc ramp will output either a preset level or the last level used. The power-up mode is stored when the control is installed. When programmed for the preset level mode, the user can store a new preset level by holding the MUTE button for more than 3 seconds.
Multiple –RLC10M 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 –RLC10M output pulse rate and width.
The –RLC10M 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. The MUTE pushbutton is a long-life switch mounted to provide protection from excessive frontal force.
All the D SERIES-RLC10M features combine to make it the ideal choice for single point or multiple location remote level control with muting 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.
