Audinate Dante Level 1 Exam Questions
With Correct Answers
On a Dante Network, there must be a different clock leader for each sample rate on the network.
- answer✔One clock leader will provide synchronization to all Dante devices, regardless of their
individual sample rates or frame rates
A 1Gbps network switch can manage more Dante channels than a single 1Gbps link can? -
answer✔A nonblocking network switch will be able to handle the total of all ports capacity at all
times.
An audio subscription (connection) can be established between two Dante interfaces operating at
different bit depths. - answer✔Like most digital audio devices, Dante devices will usually be
able to add missing bits or truncate extraneous bits to match the expected internal operation.
A Dante audio subscription (connection) can be established between two Dante interfaces
operating at different audio sample rates. - answer✔Each Dante interface can only operate at one
sample rate at a time.
What audio sample rates are supported by Dante? - answer✔Dante supports most common
sample rates from 44.1kHz to 192kHz.
If we increase the sample rate of a device from 48kHz to 96kHz, what is the impact to the
network? - answer✔A 96kHz subscription will require (roughly) twice as much bandwidth as a
48kHz subscription.
The bit depth of an audio system dictates: - answer✔the resolution of the audio signals
amplitude. A greater bit depth increases dynamic range.
The sample rate of an audio system dictates: - answer✔the audii resolution in time. According to
the Nyquist Theorem, the sample rate must be at least twice the highest audio frequency to be
captured.
Dante audio is sent: - answer✔uncompressed, bit-perfect.

Roughy how many channels of 24-bit,48kHz audio can be carried on a 1Gbps connection? -
answer✔512x512
Dante AV devices send and receive uncompressed audio and is completely compatible with
Dante audio devices - answer✔Dante AV devices transport audio and video in separate essences
so it is possible for a Dante AV device to send its audio channels to a Dante Audio device and
vice-versa
Dante AV is available in a variety of video codecs. What video codec is used by "Dante AV
Ultra" that was discussed in this class? - answer✔Compressed using a visually lossless
JPEG2000 codec.
Dante AV Ultra uses a JPEG2000 video codec and a 1Gbps connection. What is its maximum
supported resolution(s) and frame rate(s)?
Expressions here are shown in resolution, interlaced/progressive, framerate. For example,
1080p30 means 1920x1080, progressive, 30fps. - answer✔Up to 4Kp60
Dante AV devices have a scaler in it. What does the scaler affect? - answer✔The scaler can
adapt screen resolution. (i.e. - it can scale a 4K source to 1080p for display)
Which answer best describes the JPEG2000 encoding process? - answer✔There is a "visually
lossless" impact on the first encoding. Further encode/decode processes will experience no
further loss.
Interlaced video draws all the odd lines, then all the even lines. This creates two "fields" for each
frame. - answer✔The interlaced signal contains two fields of a video frame captured
consecutively. This enhances motion perception to the viewer, and reduces flicker.
JPEG2000 codecs are used in digital cinema rooms today. It is visually lossless, providing
excellent results for both video and computer graphics (like spreadsheets and slide
presentations). - answer✔The JPEG2000 offers sharp quality and intense colour definition with a
visual accuracy. It is well-adopted in professional use cases.
What factors significantly affect the overall bandwidth demands of a compressed video flow?
(Select all that apply.) - answer✔The video frame resolution (i.e. - 1080p vs 4K)
The chroma sampling (i.e. - 4:4:4 vs 4:2:0)
The frame rate (ie 24fps vs 60fps)
