Unit Connections
DANTE Inputs
The BM-A1-64DANTE provides two DANTE
RJ45 Ethernet connections (
PRIMARY
and
SECONDARY
). The primary port is connected
to the main network. The secondary port is
connected to the redundant network which should
be entirely separate to the primary network (see
www.audinate.com
for a detailed explanation on
configuring redundant networks).
Note:
If using Audinate’s Dante Virtual Network on
a PC or Mac, ensure that this is connected to the
PRIMARY
port
.
For best practice, always use either Cat-5e or
Cat-6 Ethernet cables when using Dante networks.
However, for 100 Mbps networks, Cat-5 cable may
be used.
Analogue Outputs
A pair of analogue monitor line level outputs are
provided on the rear panel. These mirror the sources
that are fed to the front panel speakers and can
either be used to feed external speakers or be used
as a breakout of the selected channel(s) from the
Dante network.
Note:
the line level outputs do not follow the mute
status on the front panel. They are always active.
AES/EBU Output
Similarly to analogue outputs above, the
AES/EBU output follows the channel selection(s) to
the front panel speaker. The output is balanced and
is compliant with AES3-1992.
Note:
the AES/EBU output does not follow the mute
status on the front panel. It is always active.
USB Port
The BM-A1-64DANTE includes a USB Type-B socket.
The function of this port is for firmware updates.

Hardware Considerations
The BM-A1-64DANTE is built in a 1U 19” enclosure.
It is intended to be permanently installed in a
standard 19” equipment rack. There are ventilation
grilles in the top, bottom and both sides of the
enclosure, and care must be taken to ensure that
these are not blocked by cables or other equipment
when the unit is installed. Do not install any other
items of equipment immediately above or below to
the BM-A1-64DANTE; the use of 1U blanking panels
is recommended.
Power Supply Considerations
The BM-A1-64DANTE is fitted with two separate,
auto-ranging switch-mode power supplies (PSUs).
The operating voltage range is 100 to 240 V AC,
50/60 Hz. The internal power rails are diode-
paralleled to the two supplies, and the unit will
operate normally if only one PSU is powered or
functional. For maximum protection when using both
PSUs, the two AC inlet cables should be connected
to mains circuits which are as independent of each
other as possible.
If redundant operation is not required, only one AC
supply cable need be connected; either AC inlet may
be used.
Fuses And Ratings
Each of the BM-A1-64DANTE’s PSUs has an internal
resettable fuse for PSU protection. These fuses
are not accessible to the user. The unit should be
powered from a mains supply (supplies) fitted with an
external HRC-type fuse (High Inrush Current) rated
at 1 A.
