DUAL MONO OR STEREO
The 320D converts between acting as two independent mono processors and one linked stereo processor by front panel selection. This is true with both analog and digital I/O.
ANALOG or DIGITAL IN, ANALOG and DIGITAL OUT !
The 320D serves as a fine A to D converter with processing. When you use the analog input, the digital output contains the Compellor's processing and is therefore ready for use in almost any application. Conversely, the 320D serves as a fine D to A converter. When you use the digital input, the analog output contains the Compellor's processing, and is properly levelled and packaged.
ANALOG AND DIGITAL AUDIO INTERFACES
The professional analog audio inputs and outputs are fully balanced and adapt to consumer or professional operating levels at the touch of a button. Analog or digital source selection is made at the rear panel.
For digital interfacing, the 320D contains a high quality 24 bit low noise codec to receive digital audio and transmit digital audio. Once the incoming digital audio is converted by the DAC section, it passes through the compellor as normal audio. The audio output is then converted back to digital by the ADC section of the codec.
The rear panel AES3 jacks are standard professional 110 ohm interfaces. There is no word clock input or output. Synchronizing is done from the AES3 input signal or an internal clock. When a digital input is present, the output is synchronized to the input sample rate. If no digital input is present, the digital output automatically locks to the internal default sample clock. The user can specify the sample rate by changing the internal crystal. Spare crystals for 32kHz, 44.1kHz, 48kHz, and 96kHz are supplied with the unit free of charge.
The model 320D codec translates the -20dBfs level of the digital audio source to the 0dB reference within the Compellor circuits. The average output levels will target around -20dBfs. The selectable peak limiter's threshold translates to -6dBfs. Thus, no digital audio output peaks will rise above -6dBfs when the limiter is on. The combination of averaging the level around -20dBfs and holding peaks below -6dBfs packages the audio perfectly for natural sound quality and for most transfer or transmission purposes. For example, the digital audio would be ready for direct input toan MP3 encoder, HD recorder, Broadcast digital STL, .wav file, etc.

The Aphex Systems Model 720 / 722 Dominator II is a stereo MultiBand peak limiter designed to fit a wide range of applications. Through the use of MultiBand techniques along with new proprietary circuits, the audibility of limiting action has been greatly reduced, especially when compared to conventional limiters. This means that greater limiting depth is possible, resulting in higher loudness with maintained audio quality. At virtually any limiting depth, the Dominator II is free of "hole punching", "dullness", and most other effects normally associated with limiters. As a peak overshoot protection limiter, the Dominator II is undetectable in line while it absolutely prevents peak levels from exceeding a user settable output level. In addition, the desired limiting effects of greater audio density and increased "punch are readily available with the Dominator II.The Model 722, for broadcast use, has the Pre and De-emphasis circuitry, while the Model 720 Does not.
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 effects, etc.
Mixing: Used as a program limiter, the Dominator II 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-to-noise without overload distortion.
Video and Audio Tape Duplication: "Hotter" transfers without saturation.
