3.3.3 Audio Output

3.3.3.1 Audio Output - CH 1-2 to CH 7-8 tabs:

Each of these tabs controls the output processing for two output channels – source selectors, level controls

and mixers for each output.

A coloured box indicates the audio type for each output of the card.

• Detected audio types can be PCM, AC3 (Dolby Digital), Dolby E or N-PCM (other non-PCM).

The Operation Mode pulldown establishes the configuration of the controls for an output channel. There are

four options:

A (see CH 1 in the figure on the right)

The source is selected using the Source A

ABUS Select and Channel pulldowns, and its

level is adjusted using the slider or data box.

• The ABUS select options are:

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 output Level is adjustable from -96 to

+12 dB with the slider or a direct keyboard

entry.

SUM (A+B) (see CH 2 in the figure on the right)

Two sources are selected using the Source A

and Source B ABUS Select and Channel

pulldowns. The two sources are added, and the

level of the combined signal is attenuated by

the amount selected in the Sum (A+B) LEVEL

pulldown.

• The ABUS select options are:

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.

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.
