Personal Mixing Systems
Configuring a personal mixing system with A360 Personal Mixers and a D800 or D800-Dante
A-Net Distributor requires one SB4 System Bridge. The SB4 can be used to combine the A-Net
outputs from up to four synchronous digital console cards and send this data to a D800 where
it will be combined and translated to the Pro16e A-Net protocol for distributed to A360
Personal Mixers. Digital console cards connected to the SB4 must have the same clock source
to avoid sync errors (pops and ticks in the audio) which will be heard in the personal mixers in
the system.
The analog AN-16/i v.2 Input Module can be used along with the A-Net console cards in a
digital console to expand the total available inputs to a personal mixing system (see page 13).
The Pro64 Series ASI A-Net Systems Interface can also be connected to the SB4 to provide up to
64 inputs from a Pro64 network to a personal mixing system (see page 14).
Using the SB4 System Bridge With a D800
The SB4 makes it easy to use multiple A-Net console cards in a digital mixing console to build a Pro16e
personal mixing system. Up to four console cards may be connected, providing up to 64 input sources that
can be assigned to the A360 Personal Mixer’s channel buttons.
If using multiple consoles, remember that the consoles need to be in sync with the same clock source
to avoid clock errors. Refer to the digital mixing console’s documentation for information about syncing
multiple consoles and using external word clock sources.

ote
: When using the SB4 as part of a personal mixing system, it is important to note that the port
labeled 1-16 must have an A-Net device connected to it. The D800 A-Net Distributor uses this
port as the source of the master clock, extracting the clock information plus the Pro16 audio
data. Devices connected to the other SB4 ports must be in sync with the same clock as the
device connected to port 1-16; their clock information is ignored by the D800.
The applications described in this section apply to both the D800 and D800-Dante versions of the A-Net
distributor product.
