BDI DAB-300-4 + I/O Panels Dual Path IBOC Switcher w/ Optional I/O Panels Included

The DAB-300 series dual path audio switchers were designed to address the need to switch two audio paths simultaneously for in band on channel (IBOC) transmission format. Maintaining time alignment between analog and digital transmitter signal paths is essential for proper performance. The DAB-300 allows the station operator to have a pair of analog and digital paths and allow them to be switched together in the event of an analog or digital audio path failure. Designed with BDI’s exclusive silence detection system the DAB-300 does its job automatically without operator intervention.

The DAB series can be operated from the front panel, GPIO, Ethernet using SNMP and/or the BDIStack Graphical User Interface available for Windows and Android devices. The GUI also provides a means of naming inputs and outputs for convenience. Couple the power of the DAB-300 with SNMP and you have the most versatile compact dual path switcher on the market. Now a simple CAT5 connection is all you need to interconnect the DAB-300 to your SNMP based remote control system or software. Whether your requirement is all AES3, analog or a combination of both its hard to find a better value in a single rack unit package.
