This listing is for one piece each, of Orban OPTIMOD 8185A TV Stereo Generator and 8182A Optimod-TV multiband compressor, loudness controller and Hilbert Clipper. OPTIMOD 8185A: The 8185A Stereo Generator is a high-performance BTSC-standard stereo generator having superb audio quality and exceptional stability. Although the 8185A will work with ANY audio processor, it is designed to be especially effective when used in conjunction with the Orban OPTIMOD-TV audio processor The 8185A far exceeds BTSC requirements, delivers unimpeachable subjective audio quality, and uses extremely high-performance low-pas filters to achieve excellent high-frequency response and the industry's best aliasing rejection. The 8185A Stereo Generator has a digital baseband encoder, group delay equalization, and upgraded noise reduction circuitry for better overall performance and tighter specifications. OPTIMOD 8182A: OPTIMOD-TV is an integrated signal-processing system which replaces conventional compressors, limiters, and clippers. It is an adaptation of the OPTIMOD-FM (model 8100A) to TV audio, and offers the TV broadcaster the same superb audio quality that has made the 8100A so popular among FM radio broadcasters. Briefly, the OPTIMOD-TV system performs the following functions It rides gain over a range of as much as 25dB, compressing dynamic range and compensating for gain riding errors on the part of operators.... It controls excessive perceived loudness by means of a complex loudness-estimating circuit that reduces the gain of the compressor VCA's when necessary. (On-air tests of the controller have indicated that it substantially reduces or eliminates viewer complaints regarding excessively loud commercials) It controls potential interference to video and/or future stereo services by means of bandwidth-limiting 15kHz lowpass filters incorporating full overshoot compensation. The OPTIMOD-TV compressor is a dual-band design which can be operated with the bands independent of each other, or such that the bands are coupled and ordinarily track each other. It prevents peak overload and over-modulation due to the effects of the pre-emphasis curve. (Manuals for both pieces of equipment are readily available online via a google search for 8185a and 8182a) This listing is for one piece each of the 8185A and the 8182A.
