Plug-on Transmitter


The Digital Code System is a major technological advance, offering the best solution to the most common and incurable type of interference, which is an external RF signal on or close to the wireless operating frequency. Digital technology is combined with advanced circuit and mechanical design for an overall package clearly superior to any other wireless system in this price range.

A digital code is factory programmed into each transmitter/receiver combination to create a unique control signal for the audio output, rather than simply detecting the presence of an RF signal. Another transmitter on the same frequency cannot open the audio output on a DCS™ receiver, unless it also has the same code. With 6561 different codes available, and dozens of frequencies between 169 and 216 MHz, interference can easily be avoided. The receiver will always remain completely silent during idle periods. Clicks and pops at turn-on and turn-off are also eliminated by the DCS system.

An advanced compandor system reduces noise and hiss to inaudible levels, without the “pumping and breathing” typical of lesser designs. A limiter in the transmitter input prevents overload distortion and further improves the signal to noise ratio of the system.
