9. Operation under ASIO 
9.1 General 
Start the ASIO software and select ASIO MADIface USB as the audio I/O device or the audio 
driver. 
The Digiface AVB supports ASIO Direct Monitoring (ADM). 
9.2 Channel Count under ASIO 
In Single Speed  Speed  (44.1 and  48 kHz) 128  input and output  channels each are  available. 
Double Speed (88.2 and 96kHz) reduces the  number of available channels to 64 each. Quad 
Speed (176.4 and 192kHz) reduces the number of available channels to 32 each. 
Through TotalMix FX, the 128 input and 128 output channels of the hardware (the network) are 
fully accessible even at 96 kHz (at 192 kHz Digiface AVB still supports 60 network channels). 
Note
:  When  changing  the  sample  rate  range  between  Single,  Double  and  Quad  Speed  the 
number of channels presented from the ASIO driver will change too. This may require a reset of 
the I/O list in the audio software.
