Page 3: Basic Description
Input and output types are defined by the model number as shown above. The ATB-300 can be used to manually switch inputs or will automatically switch when a programmable silence interval of between 10 and 600 seconds is detected. -
Page 4: Atb-300 Operational Mode Descriptions
When the select key is pressed the new selection is stored to memory and the audio is switched. This setting is NON VOLATILE. If the ATB-300 is power cycled this channel will be selected on power Figure 1 - ATB-300 Manual Mode Display In manual mode the user may also program the priority memories, the silence interval and the relative audio threshold which triggers the active / inactive determination. -
Page 5: Memory Programming
PRI 1 CH 1 NO AUDIO INPUT: CH 1 NO AUDIO Figure 2 - ATB-300 Priority Memory Programming Mode Display Pressing the F2/F5 key will enter the memory programming mode. In this mode, the top line of the LCD indicates the current memory (PRI 1 to PRI 8) being programmed, its contents and the activity status of that channel. -
Page 6: Silence Threshold Programming
PRI 1 CH 3 NO AUDIO Figure 5 - ATB-300 Auto Mode Display When the ATB-300 detects an audio level below the silence threshold for the pre selected time interval it will look at the priority memories and switch the lowest priority channel which is active to the output. -
Page 7: Remote Control Operation
The ATB-300 provides remote inputs for channel selection via rear panel GPIO, via Ethernet by use of the BDI Stack GUI and for all ATB-300 units with S/N 211 or greater can utilize SNMP for use with SNMP enabled remote controls. The SNMP MIB is contained on the CD provided with the unit and is also available for download from the BDI web site under downloads. - Page 8 To enable remote channel selection, the ATB-300 must be in MANUAL mode. When the ATB-300 is in MANUAL mode, connecting a remote channel select input to remote common momentarily will cause the corresponding input to be selected as the current output.
- Page 9 As with any programmable device, it is possible that the user would like to quickly return to the “factory default” settings. To return the ATB-300 to its factory configuration remove AC power to the unit. While holding the red “X” key, restore AC power until the display indicates “FACTORY DEFAULT”.

Page 14: Ethernet Setup
The ATB-300 is capable of outputting 32, 44.1 or 48 KHz sample rates. The factory default sample rate is 44.1 KHz. To change the sample rate to either 32 or 48 KHz refer to the diagram below. The sample rate converters are located on the AES I/O board. - Page 15 After installation of the unit connect your unit to a router connection or directly to a laptop using the RJ45 LAN connection on the rear of the unit. The default IP address is: 192.168.1.150. Port 161 is default from the factory and can be reset but make certain that the new port is forwarded for external access if desired.
