FOR-A aspired to create an unprecedented product with the FA-128, and to this day it remains the only 14-bit processor of its kind on the market.

	The FA-128 ~~features~~ superior correction range and image quality ~~thanks to~~ its 14-bit quantization—the highest bit depth available in its class ~~at the time of release.

The FA-128 accepts analog composite video input and provides four simultaneous composite outputs, making it suitable for distribution applications as well as signal processing. The superior correction range and image quality come from its 14-bit quantization—the highest bit depth available in its class.

	A digital 3-line adaptive comb filter accurately separates luminance and chrominance from composite signals while maintaining full bandwidth~~. Full frame memory with 2-field correction range prevents picture field inversion during processing~~.

A digital 3-line adaptive comb filter accurately separates luminance and chrominance from composite signals while maintaining full bandwidth.

	The unit automatically detects NTSC or PAL input signals. Front panel proc amp controls allow adjustment of video level (±3 dB), chroma level (±3 dB), setup level (±15 IRE), and chroma phase (±30°). Genlock phase control provides H phase (±2 µs), SC phase (±180°), H position (±2 µs), and V position (-128 to +127 lines) adjustment.
