4. Ensure the ON buttons for the channels in use and for the STEREO slider are
illuminated; also verify no SOLO buttons are illuminated (Figure 20).
5. Bring sliders up slowly and listen for the signal (Figure 21).
6. The signal should be visible on the STEREO output meter
(Figure 22):
 The amber LEDs indicate that the level is near clip.
 The red LEDs indicate that the signal has reached the
digital limit.
REMEMBER: Bad input = bad output. No adjustment on the mixer
can make a poor source sound better. For best results, be sure to
use high-quality audio files from your MP3 player or laptop, and
set the device to near full volume.
