Overview
Stereo Spatial Enhancer
The Orban Stereo Spatial Enhancer 222A augments your station's spatial image to present a more dramatic, more attractive sound. The stereo image is magnified and brightness is intensified, so listeners perceive an expanded stereo "soundstage" with increased depth and sparkling clarity. Unlike other units, the 222A does not add harmonic distortion, unnatural coloration or exaggeration of the reverb on recordings. The effect of the 222A is particularly striking in automotive listening.

Notes
Why Stereo Spatial Enhancement?
In contemporary broadcast audio processing, high value is placed on the loudness and impact of a station compared to its competition. Our industry-leading OPTIMODŽ processors have already made a major contribution to competitiveness. The Orban 222A Stereo Spatial Enhancer augments your station's spatial image to achieve a more dramatic and more listenable sound. Your stereo image will become magnified and intensified; your listeners will also perceive greater loudness, brightness, clarity, dynamics and depth. The 222A can also be used to convincingly process final CD or cassette stereo masters. It expands the stereo soundstage without introducing harmonic distortion or other unnatural coloration.
A Competitive Edge Without Distracting Side Effects
There have been many prior attempts to process stereo signals to increase width and dimensionality by altering the ratio of L-R signal to the L+R, but each has fallen functionally short of the performance achieved by the 222A. The 222A does not increase sensitivity to vertical tracing distortion in disc playback, does not exaggerate reverberation, and does not increase multipath distortion. The 222A has been extensively tested in real-life, high multipath environments. These tests have resulted in uniformly rave reviews.
Most of All - Affordable Enhancement
In the refinement of your station's audio processing, you've no doubt become aware of equipment that's overhyped, over-priced and under-powered. The 222A Stereo Spatial Enhancer is affordable, and it works! The 222A's effect is subtle in headphones but decisive on the road. Find out how well it works by trying it on the air, with your own format and your processing chain, and monitor it where it counts-in a vehicle on the road throughout your listening area. Contact your Orban Dealer and arrange for a demo of Orban's unique dimension in audio processing. We think you'll find that our 222A is a powerful, competitive weapon that's just right for your image.
