Two sources are selected using the Source A and Source B ABUS Select and Channel pulldowns. The

o V select one of the 16 channels from the video card.
o A1 select one of the 16 channels from an audio card. A1 is always Local, Slave 1 or Master
o A2 select one of the 16 channels from an audio card. A2 is always Slave2 or Slave.
• The Sum (A+B) Level pulldown offers attenuations of 0 dB, -3 dB and -6 dB.

routed to this output and the Source A audio type will be displayed. The Source B signal will be
ignored.
