RDL DS-RLC10 Remote Level Control, Rotary (Stainless Steel)

The stainless steel DS-RLC10 Remote Level Control from RDL is a rotary remote level control that provides user adjustment at a single or multiple locations. This control is designed to fit any standard single-gang electrical box. The optical encoder technology allows continuous knob rotation with a comfortable adjustment rate and long-term, trouble-free, and noise-free operation. The control directly connects to any RDL, VCA, and OEM equipment with 0 to 10 VDC ramp inputs.

The DS-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 the DS-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 DS-RLC10 output pulse rate and width.
