Description
The FOR-A FA-128 is a signal processor featuring the world's first 14-bit digital encoder/decoder, introduced in January 2005. 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 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.
Internal signal processing uses 4:2:2 component format with sampling frequencies of 13.5 MHz for luminance and 6.75 MHz for chrominance. 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. 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.
A modular version (UFM-128FS) was also available for installation in FOR-A's universal frame system.
