As the input increases above threshold, the output takes the shape of the de-emphasis curve. When both pre and de-emphasis are switched out, the Model 722 works exactly like the Model 720. RCH DENSITY - adjusts RANGE - when switched the Relative Crest Height to the “.10” position it adds ach (RCH) of the output. a 10dB boost in the input The higher the RCH and a 10dB cut in the and of (clockwise) the louder the output. The PEAK CEILING output. The lower the is therefore 10dB lower nnel RCH (counter-clockwise) than the settings shown of the lower the average on COARSE and FINE level in the output. controls. Applications Sound Contracting — protection of amplifiers and speakers from overload; increased loudness; maximized use of available power. Recording — preventing sudden peak overload of mixer or recorder; tightening tracks; special eff e c t s , e t c . Mixing — used as a program limiter, the Dominator ll will keep a track “rock steady” for “layering” into or on top of a mix. Digital Sampling — obtaining good full scale samples free from peak overload, i.e. no more missed samples. Digital Recording — insuring clean recording by stopping clipping of peaks and overshoots. Maximizes bit usage for less distortion. Satellite Uplink — Modulation control to prevent splattering on high frequency audio, gives reduced distortion, better signal-to-noise. Broadcasting — AM and FM modulation control for increased loudness; cleaner sound; use in production for greater consistency of tapes, punchier voice-overs. Location Film Shoots — anti-crash for dialog and sound effects recording. Post Production — Soundtrack peak control; managing difficult dialog; controlling transient sound effects. Optical Recording and Transfer — prevents “valve clash”, gives higher average level with low distortion and better signal-to-noise performance. Analog Disk Mastering — peak control for high allowable average cutting levels; less limiter degradation to the program; brighter, punchier sound. C/D Mastering — peak and density control for more accurate digitizing, cleaner sound requiring less error correction on playback; no limiter induced sound degradation. STL & Phone Line Driver — maximize signal-tonoise without overload distortion. Video and Audio Tape Duplication — “Hotter” transfers without saturation. LIMITING (meter) displays the limiting (from gain reduction and clipping) in the channel with the greatest amount of limiting. he FINE - adjusts the COARSE - switches POWER - switches en PEAK CEILING by the PEAK CEILING AC mains on and off. om ±1dB in 0.2dB steps. in 2dB steps from +2 to +24dB(pk). “Off” position engages bypass relays.
