Changing the output volume level
Users can set the volume level for each local audio output volume level from the I/O Settings
page. Volume is adjustable through a range of zero steps of attenuation (full attenuation,
minimum volume) to 64 steps of attenuation (no attenuation, full volume).
Change the audio volume setting for an output as follows:
1. Click the Volume drop box for the desired output. A drop-down scroll box appears
(figure 75).

2. Click and drag the slider or click on the scroll up button or the scroll down button
until the desired value is visible.
NOTES: • As an alternative to steps 1 and 2, listen to the audio as you make
adjustments by clicking the up button or down button.
• The table on page 75 defines the value of each audio volume step. The
X1( references in the table are SIS command variable only and have no
meaning for HTML volume adjustment.
Muting and unmuting an audio or RS-232 output
Mute and unmute an audio or RS-232 output by clicking the associated Audio
