• Channel count – How many channels are currently being
streamed to and from the mixer. This can be changed only
from the mixer’s LCD screen. (Note): The numbers here
are relative to the computer. If the driver is Unlocked,
additional information is displayed here about the state of
the individual streams of FireWire data. All streams must
be locked for audio to be sent.
• Audio Dropouts – displays how many buffers have been
lost so far since locking. This should be a small number, as
it is normal for the driver to lose a few buffers when it
initially connects and negotiates the correct speed. Check
this before and after a recording or mixdown to see if your
computer was able to keep up throughout. If this number is
increasing each time you check, your computer is not
providing data fast enough – try reducing channel count or
other CPU load.
Configuration Panel
This shows the following information about the “far end” of the
connection.
• Firmware version – The version of the IF-FW/ DM
MKII’s
internal firmware.
• Device – the type of the connected device, e.g. DM-3200 or
DM-4800.
Settings Panel
The settings panel has the following parameters.
• Buffer size in samples – This sets the overall latency and
CPU load of the drivers. Smaller numbers will reduce
latency (audio delay) but increase system load. Do not set
this value smaller than the value shown below.
• Minimum Buffer size – This shows the minimum buffer
size that the driver can process on your computer at the
current FS. Setting the buffer size smaller than this value
will result in no audio, or distorted audio, you must choose
a buffer size larger than this value.
