HHa General Technical Description Introduction Digital Hybrid Wireless® Technology The HHa handheld transmitter uses state-of-the-art Digital Hybrid Wireless® wireless technology, selectable output power and a versatile microphone capsule mounting system to meet the needs of audio professionals and vocalists. The compandor-free Digital Hybrid audio chain preserves the quality of the selected microphone capsule and delivers it to the sound and recording system without coloration.
Wideband Hand Held Transmitter Pilot Tone Squelch The benefit of the pilot tone squelch system is that the associated receiver will remain muted until it receives the pilot tone from the matching transmitter, even if a strong RF signal is present on the carrier frequency of the system. All Digital Hybrid Wireless® transmitters use one of 256 different ultrasonic tones between 25 and 32 kHz in each standard frequency block to operate the receiver squelch.
