D-RLC10

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.

NOTE: This equipment has been tested and
found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC
Rule. These limits are designed to provide
reasonable protection against harmful
interference in a residential installation. The
equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in
accordance with the instructions, may cause
harmful interference to radio comm unications.
However, there is no guarantee that interference
will not occur in a particular installation. If this
equipment does cause harmful interf erence to
radio or television reception, which can be
determined by turning the equipment off an on,
the user is encouraged to try to correct the
interference by one or more of the following
measures:
 Reorient or relocate the receiving

antenna

 Increase the separation between the

equipment and receiver

 Connect the equipment into an outlet on

a circuit different from that which the
