ister to control its level. In the Attenuation window, there is
a slider for each attenuator register. Use the slider handle or
the arrows at each end of the slider to adjust the attenuation
level. The left and right arrow keys on the keyboard can also
be used to adjust the level. Just below each slider is a status
display showing the current register setting (in decimals)
and the corresponding attenuation level in decibels (dB).
The Operational Control Window
The Operational Control window is shown in Figure 13.
This window is used to set the following functions:
Soft Mute (Mute Lch, Mute Rch): ON or OFF
DAC operation (DAC Lch, DAC Rch): ON or OFF
Digital De-Emphasis (DEM): OFF, 32kHz, 44.1kHz, or 48kHz
For more information regarding these functions, refer to the
