when the channel's input signal reaches -6 dBFS (+4 dBu). The red clip indicator LED will illuminate
when the channel's input signal reaches 0 dBFS. At this level, the mic preamp/line trim signal of your
external A/D will exhibit signs of clipping, and undesirable type of distortion. Do not allow your
converters to clip.

External Sync Indicators. The FireStudio Lightpipe has two external clock-source (sync) indicators on
the front panel to let you know at glance if your FireStudio Lightpipe is receiving a stable sync source
from either BNC or ADAT. If you assign an external clock source in the FireStudio Lightpipe Mixer
application, these lights will tell you if your unit is receiving word clock correctly. Word clock is the
manner by which digital devices sync frame rates. Proper word-clock sync prevents digital devices from
having pops, clicks, or distortion in the audio signal due to mismatched digital audio transmission.
