• Main. The Main knob controls the output level for the Main Outputs on the back of the FireStudio
Project with a range of -80 db to +10 dB.
• Phones. The Phones knob controls the amount of volume going to the headphone output on the front of
the unit. Notice the volume indicator goes to 11 … use this setting with extreme caution.
• ¼” Headphone Jack. This is where you connect your headphones to the FireStudio Project.
• Red-Blue Power/Sync Light. This light is a clock source (sync) indicator. It lets you know 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.
