Abstract: An audio transducer system, such as in-ear monitors, are connected to an audio base unit, such as a receiver body pack, using a bidirectional serial time-division multiplexed link. The bidirectional connecting cable has a single active conductor and a ground wire, a detachable connector to the receiver body pack and, preferably, a detachable connector to the sin-ear monitors. The invention provides for bidirectional communication between the audio base unit (receiver body pack) and the audio transducer system (in-ear monitors) and enables simultaneous and automatically configured DC power supply depending on the identified requirements.

Abstract: Methods and devices are provided whereby deficiencies in the impedance of a cable connecting an electric guitar and a wireless transmitter or other audio device may be electronically corrected, according to user preferences. User settings may be saved and recalled as needed from a program interface that serially communicates with electronics controlling the behavior of the cable.

Abstract: A lavalier microphone has improved dynamic range. The lavalier microphone incorporates a pair of microphone transducer elements into the same housing or attached housings, with one of the microphone transducer elements being more sensitive to acoustic input than the other. The voltage signals from the respective transducer elements are processed and combined, resulting in a digital output audio signal with improved signal to noise both at lower and higher input acoustic levels.
