CHAPTER 1
Introduction
Overview
The ADHB-4 (Advanced Digital Headset Box - P/N PRD000262000) is easy to install and configure dispatch audio system
that adds microphone and speaker capabilities, in various forms, to a C-Soft console. The ADHB-4 replaces the sound card in
the PC, offering the flexibility of controlling a wider selection of audio options.
Audio input and output is routed to devices by connecting a combination of headsets, desk mic, speakers, or a telephone to the
unit. Electret and dynamic microphones are both supported. Additionally, a footswitch can be installed for hands-free
operation. The unit can be mounted on the desktop or below it. Standard cable connections are made directly to a PC, to access
C-Soft, and an Ethernet connection for firmware upgrades, and unit configuration.
Audio parameters are set up within the web browser configuration software. Access to the radio dispatch system is provided
by configuring the base IP Address, Subnet Mask and Gateway within the ADHB-4 software. Additionally, the input and
output gain control, PTT (Push-To-Talk) source, and PTT priority are configured for the connected audio equipment. Status is
conveniently summarized on one (1) window in the configuration software for quick evaluation of connected audio devices.
The front panel is equipped with a color TFT-LCD (Thin Film Transistor-Liquid Crystal Display), allowing instant
indications for ADHB-4 activity. The console operator can quickly determine which device audio is being routed to/from, as
well as footswitch activity, volume, transmit status and receive status. A bar graph indicates the headset volume level and can
be changed with the volume buttons on the front panel. A system information menu is also available. A single LED (Light
Emitting Diode) on the front indicates power when green and PTT when red. A single red LED on the left side panel indicates
phantom power is enabled when red and disabled when dark.
Softkeys on the front panel allow the console operator to change the clock, adjust the display’s backlight brightness, and
change the IP Address and Subnet Mask.
