Dante network audio
connections for Choirflex-D
Two Ethernet connectors are provided for connection to
the Dante™ network, labeled
PRIMARY
and
SECOND-
ARY
. If using a single network, connect the
PRIMARY
connection to your Dante-compatible equipment or eth-
ernet switch. If also using a redundant network, connect
the
SECONDARY
port to that network.
Do not connect
the PRIMARY and SECONDARY ports to the same
network at the same time as this may cause unstable
operation!
Note that, at this time, Choirflex is only compatible with
Dante systems running at a sampling rate of 48kHz.
Dante audio patching
Dante network audio channels must be patched using the
Audinate Dante™ Controller software application. This
application may be downloaded for free from
www.audinate.com
and is available for Windows or
MacOS.
Choirflex will appear in Dante Controller with 128 chan-
nels of input and output. Only the first four (4) inputs and
outputs are active, with inputs labeled
CHOIR
and
REFERENCE
, and outputs labeled
CHOIR
and
SPLIT
.
These may be connected to other devices in your system
(mixing consoles, signal processors, preamplifiers, etc.).
Note that standard Dante unicast and multicast rules may
be employed, as long as all devices connected are using the
same 48kHz sampling rate and a common clock master.

1
CHOIR input. Connect the unprocessed stereo choir
mix to these inputs. This may be from an external choir
pre-mixer, or from a dedicated stereo group bus within the
house console.
2
REFERENCE input. Connect a stereo reference signal here
that is equivalent to the main loudspeaker mix output of
the house console.
3
CHOIR output. Connect these outputs to two console in-
puts on the mixing console. These contain the choir sound
that should be mixed to the house speaker system.
4
SPLIT output. These are extra outputs carrying the same
signal as the CHOIR output, and can be used to feed re-
cording or broadcast equipment.
