The remote units are easily wired, in “daisy-chain” configuration, using simple modular telephone style cables. Up to four RC-16 remotes can be connected to a given control input (and that remote, or string of remotes, can be “daisy- chained” to control up to 64 audio channels). The system provides 29 steps of precise 1.5 dB attenuation from 0 to -43.5 dB, with a 30th step for 90 dB “full kill” attenuation. Virtual display of the set attenuation is simultaneously given at all locations via a circular LED array around the knob on each RC-16 Remote Control. The RC-16 can be mounted in a standard two-gang electrical wall box, or a pre-punched 2-gang plate is available from Oxmoor. The RC-16 is actually a highly sophisticated shaft encoder which translates knob movements into a string of digital pulses; the pulses then alter the level of the digital attenuator(s) within the DCA-2 chassis. Unlike up/down buttons, the RCA-16 is sensitive to rate-of- change, and thus the faster the knob is turned, the faster the setting is changed. As any interconnected RC-16 knob is turned, the LEDs on all remotes in the chain follow until the upper or lower limit is reached.

At that point, the knob will continue to turn, but the level and Virtual Pointers simply stop changing until any one of the knobs is turned in the opposite direction. Since there are no mechanical stops, a knob cannot be “twisted off” if it is turned beyond what would be the “stop” positions on a conventional level control. For applications where access to one or more remote controls must be restricted, a key switch can be installed in place of a jumper on the back of the RC-16 the key switch must then close to activate the RC-16.
