Reference In
—if desired, supply a composite analog reference signal, such as house black. Locking the board to an analog reference source, or to a digital input (setting Input 1 as the Reference Source in the Control Panel), guarantees frequency 

accuracy. For HD reference, use Tri-level Sync as defined in SMPTE 274m. For 1080 modes only, you may also use analog 525 or 625 “color black.”
