LX-220A
NTSC / PAL BLACK-BURST GENERATOR
The LX-220A provides a convenient source of composite black-burst for preblacking tapes or for
synchronization purposes. Eight isolated outputs are provided on rear mounted BNC connectors.
The output signal consists of sync, blanking, reference black setup level and color burst which is
SCH phased. The LX-220A employs a temperature-compensated crystal oscillator for high stability.
A sinewave tone, at 0 dbm (2.2 vpp), is accessible on the rear-mounted RCA connector. The
frequency of the tone is selectable (400 Hz or 1 KHz) with a front panel DIP switch. The other front
panel DIP switch allows the unit to be switched between NTSC (RS-170A) and PAL composite video.

LX-221
“GENLOCKABLE” BLACK-BURST / SYNC GENERATOR
The LX-221 is a six output Black-Burst / Sync Generator. The unit features enhanced black-burst
circuitry and extremely precise stability. LX-221 provides a convenient source of RS-170A composite
black-burst for pre-blacking tapes or for synchronization purposes. The unit may be genlocked to
an external source of video or operate in stand-alone mode. In stand-alone mode the unit references
an internal voltage-controlled, temperature compensated crystal oscillator. If the signal is lost
when operating in genlock mode, the unit automatically references the internal crystal.
Features
• Enhanced Noise Suppression Circuitry • Six Isolated Composite Black Outputs
• Excellent Temperature Stability • Genlockable
Six isolated outputs are provided on rear mounted BNC connectors. Each output signal consists of sync,
blanking, reference black setup level and color burst which is SCH phased. The subcarrier frequency may
be adjusted internally if desired (internal reference only). An LED indicator and toggle switch are located
on the front panel. The LED is lit when the unit is operating in genlock mode.
