Without digital signal connected to the input “AES 1”, AES1
clock selection is displayed as “not valid”.
·
Buffers: these parameters allow adjusting the latency of the
CANCUN device.
· Streaming: this is the lowest level of buffering, which impacts the
latency in DirectSound as well as in ASIO.
Possible selections are: min latency, low latency, standard, relax,
safe, extra safe.
· ASIO: this is the buffering used by the ASIO driver, in samples.
Possible values are: 64, 128, 256, 512, 1024, 2048, 4096, 8192
samples.
The minimum selectable value depends on the
parameter “Streaming”.
When “Streaming” is set to “low latency” , all values are allowed.
When “Streaming” is set to “extra safe”, values higher or equal to
2048 samples can be selected.
Note: minimum latency settings require good PC performances.
