“IBC is the main platform for Sonifex to launch and showcase new product designs and this year we have a number of broadcast product additions to interest our customers. Our new talkback and communications products include two headphone amp belt-packs and GSM/PSTN comms links for our talkback controller,” reveals Sonifex managing director Marcus Brooke.
The new portable, battery powered belt packs are the CM-BH4W 2-wire/4-wire headphone amp with speaker and the CM-BHA headphone amplifier with limiter & loudspeaker, for use in live applications such as in-the-field news reports. The CM-BH4W uses audio transformers at its input and output, providing galvanic isolation and ensuring that communications are loud and clear. It can operate in 4-wire and IFB modes with an AGC to maintain output level, using a talk switch which can be latching or momentary. The CM-BHA has a wide incoming signal gain and an adjustable limiter to prevent and indicate excessive levels. Both units have a long battery life (up to 200 hours on one 9V battery) and a low battery warning LED.
