Usage Cases
N.B. The following diagrams omit secondary network connections for clarity.
Standalone Sample Rate Conversion of Dante Sources
The HC Bridge SRC contains two independent Dante HC cards. These each offer 256 channels of
conversion between Dante network audio and serial audio data with SRC functionality. With one HC
card set to a sample rate of 48 kHz and the second set to 96 kHz, when the serial audio data
connections are looped between the two Dante HC cards this provides 256 channels of sample rate
conversion in each direction.
A Dante network can contain devices operating at different sample rates, but only devices operating
at the same sample rate can have routes made between them. Using the HC Bridge SRC as a
standalone sample rate converter provides a go-between for routing a large number of channels
across devices running at different sample rates.
Both Dante HC cards will appear on the Dante network. Audio routed to one Dante HC card will be
available for routing from the corresponding output of the second Dante HC card at the new sample
rate.
Connection of Dante Devices Operating at a Different Sample Rate
With SRC functionality enabled each Dante HC card can convert incoming Dante network audio to
the sample rate of a connected HC Link card in a Tempest Engine.
For example, a Dante network may have some I/O devices running at 48 kHz and others at 96 kHz.
A System T console running at 48 kHz would only be able to route audio to and from the devices at
48 kHz. With an HC Bridge SRC containing an HC card set to 96 kHz it would become possible to
route 256 channels to and from the Dante devices running at 96 kHz. Setting both Dante HC cards
within the HC Bridge SRC to 96 kHz would double the channel count to 512 channels.
Tie Lines to a Second Dante Domain
With no clocking dependence. For operational or security reasons a facility may have multiple Dante
Networks. These may not be clocked from the same systems.
N.B. This is not to be confused with Dante Domain Manager and shared audio between domains.
However Network I/O HC bridge SRC can easily be used to provide tie lines between DDM managed
Dante domains with different clocking.
Dante Controller
HC Card Reset
Resetting the Dante HC cards to default settings is performed from Dante Controller. Under the
‘Device Config’ tab for a device select ‘Clear Config’. This clears the device name, channel labels, IP
address settings, sample rate, latency, and existing audio routes.
