The Orban Rx Adaptive Enhancement Processor is an efficient and powerful production tool that “brings sound to life” by increasing the definition, detail, and intelligibility of both single tracks and mixed program material. It is applicable to almost all areas of professional audio, including recording, motion picture and video sound, post-production, electronic music, sound reinforcement, and radio and television broadcasting. Restoration Circuitry: • Distortion-canceling Harmonic Restoration adds detail-enhancing second harmonic energy without introducing difference-frequency intermodulation (IM) distortion. • Dynamically-controlled Spectral Restoration analyzes the spectral balance of input material and dynamically re-equalizes as necessary to improve definition and increase realism. It operates simply with a single spectral level control. • tuning and level controls, familiar to users of other enhancement processors, are provided in the Harmonic Restoration circuitry. Dynamic Single-Ended Noise Reduction (DSNR): • DSNR circuitry combines a subtle downward expander with a program-controlled low-pass filter to achieve significant noise reduction without pumping, breathing, or loss of intelligibility. • In addition to reducing noise that could be added by enhancement, the DSNR circuit can reduce noise to below the noise level of the original signal. • Separate threshold controls are provided for the Downward Expander and Dynamic Filter. • Downward Expander Gain Reduction and Dynamic Filter Bandwidth are each metered by ten-segment LED meters, facilitating easy adjustment of the threshold controls. System Features: • The true peak-reading PEAK OUTPUT meters are used with each channel’s output level control to detect and correct clipping. • The three-position signal restoration switch enables un-enhanced (bypass mode), Rx-enhanced (Rx mode), or enhancement sidechain (detail mode) signals to be heard and compared. • The STEREO COUPLE switch can force left and right expander gain reductions to track, maintaining correct stereo imaging. • Inputs and outputs are transformerless, balanced, and floating. • Inputs accept -lOdBV and +4dBu signal levels. • The Rx features extensive RF suppression on its input, output, and power leads.
