Getting Started Guide:
Powering On
During power-on, the meter panel is blanked initially. The whole system is ready to work after a UNIKA (see
the picture below) shown on the meter panel for about 3 seconds.
Do not power on the device immediately following a power off.
At least wait for 10 seconds before you re-
power the device. Fail to do so can make the power supply in the device restart from unknown state.
Sample Rate Setting
Every device in a Dante network must be configured to work in the same
sample rate.
Set the first two DIP switches on the rear panel to determine what
sample rate you need, then long press the Sample Rate set button until you see a
SET (see the picture below) shown on the meter panel. You will see the sample
rate status LED on the front panel reflecting the setting you expect. Please be
notified that the sample rate can be changed by computer running Dante
Controller software or Dante-enabled audio consoles. To determine what the
sample rate is adopted in the device, please always look into the sample rate
status LED on the front panel. The position of DIP switches on the rear panel is not necessary to be an
indicator of the sample rate adopted in the device.
Redundant Mode:
There are two Dante network ports in the device. By default, these two ports are configured to work in switch
mode (a.k.a. Daisy-chain mode). In switch mode, the streaming audio data going into any one of the ports will
also switch forward out to the other port, and vice versa. That means you can simply treat these two ports as
loop-in/loop-out ports, but bidirectional. That is to say, you can cascade several NBB-1616s in the same
network link if their Dante ports are all configured to work in switch mode.
You may want to configure the two network ports to work in redundant mode to gain the benefit of reliability.
To toggle the mode setting, simply long press the Redundant/Daisy-chain button on the rear panel until you
see a SET shown on the meter panel. The device will be restarted itself and come out with the mode toggled.
You can confirm whether the mode is changed by looking into the Redundant status LED on the front panel.
In the redundant mode, the two network ports are work virtually independently but the audio transceived over
them are exactly the same. That means you are redundantly routing audio over two network links and the two
links are backing up each other. If any one of the link fails, the audio won't be interrupted because the other
link can keep streaming the audio seamlessly.
