Input Invert Control modes are automatically saved when selected. To exit this menu

press the F1 key to return to the main menu.

Press F4 three times to enter Input Gain Control menu

Pushing the up arrow/down allows you to select the input channel to be changed:

Pushing the left/right arrow buttons allows you to adjust gain in one dB increments +/-

10 dB

Press F4 four times and the display will indicate Output Gain Control

Pushing the up arrow/down allows you to select the output channel to be changed:

Pushing the left/right arrow buttons allows you to adjust gain in one dB increments +/-

10 dB

Factory default for input and output gain controls is 0 dB. When factory default gains are

used AES3 I/O is unity. When AES3 inputs are output to an analog channel the analog

output will correspond to –10 dB below full scale AES3 input when AES3 input is

nominal – 10 dB below full scale.

DAB-300 Factory Default Recovery

As with any programmable device, it is possible that the user would like to quickly return

to the “factory default” settings. To return the DAB-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”. The default condition is such that outputs 1

through 4 are fed by input 1 and outputs 5 through 8 are fed by input 5.

V. Automatic Silence Detection Setup

Push F3 once to enter the silence detection setup menu. Doing so presents the user

with a dialog which sets the silence detection interval. The factory default silence

detection time is 60 seconds. Values ranging from 10 to 600 seconds may be selected

using the up and down arrow keys. Broadcast Devices strongly suggests that silence

detection intervals of less than 60 seconds be tested carefully to verify that normal

program content does not cause undesirable switching.

Push F3 a second time to select the silence detection threshold level. This is the audio

level below which the DAB-300 considers the input to be silent (inactive). The factory

default silence threshold is “5”. This level may be changed using the up and down arrow

keys.
