•  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 
MK
II’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.
