Controls and Indicators
Figure 5
See
1. Channel A CLIP indicator – illuminates red when the input is high
enough to cause the channel to clip.
2. Channel A SIG (signal) present indicator – illuminates green when
there is a signal applied to the input.
3. Power Switch/LED on/off – Illuminates blue when on.
4. Adjust Channel A GAIN
5. User Interface
a. HOME – go to HOME screen / view current PRESET
b. ENTER – select highlighted item and/or confirm parameter change
c. EXIT – return to previous screen and/or undo parameter change
6. Adjust Channel B GAIN, selects and adjusts controls
7. Channel B SIG (signal) present indicator – illuminates green when there is a signal applied to the input.
8. Channel B CLIP indicator – illuminates red when the input is high enough to cause the channel to clip.
