The ADHB-4 Gen 2 is the perfect companion to C-Soft. The ADHB-4 Gen 2 works with C-Soft and eliminates the variability of computer sound cards for both input and output. The ADHB-4 Gen 2 represents the second generation of this proven audio interface platform. All of things users have come to know and love about the ADHB-4, such as a variety of microphone, headset, and handset options, along with up to six audio outputs, NENA port, mounting options, etc. are there. The unit sports a new display and front panel along with a back panel that has added a two channel auxiliary audio input via a 3.5mm stereo jack, which allows users to bring in other audio feeds, such as audio from a broadcast news channel.
