pulldowns. The two sources are mixed, with the
level of each source adjusted using its slider or
data entry box.
• The ABUS select options are:
o V selects one of the 16 channels from
the video card.
o A1 selects one of the 16 channels from
an audio card. A1 is always Local,
Slave 1 or Master
o A2 selects one of the 16 channels from
an audio card. A2 is always Slave2
or Slave.
• The contribution of each of the sources to
the mix is adjusted using its Level slider or
direct keyboard entry into the data box,
over a range from -96 to +12 dB.
NOTE: If you attempt to mix two different audio
types to an output, only the Source A
signal will be routed to this output and the
Source A audio type will be displayed. The
Source B signal will be ignored.
