The AKG BX 5 is a compact Stereo Reverberation Unit utilizing the patented Torsional Transmission Line principle (TTL). It possesses the exceptional sound qualities inherent in our BX 20, BX 15 and BX 10 Reverberations Units, but is compactly designed in a rackmount configuration. The BX 5 Is a single transmission line system with stereo inputs and outputs, both being balanced, and levels and impedances are fully compatible with those commonly used in broadcasting and recording. High reverberation quality is assured through the patented AKG Torsional Transmission Line system, with highly smooth reverberation characteristics made possible by a series of springs whose transmission properties have been controlled by statistical variations of the spring parameters. Our patented reverb system is the only reverb device ... including live chambers . .. which does not contain any of the dry input signal at its output, and yields flutter-free performance. To maintain optimal reverb quality, the TTL system also provides a frequency-dependent decay-time characteristic. Truly balanced reverberation Is obtainable at any decay-time setting. In recording studios, the BX 5 will find broad application as a primary reverb source, yet Is economical enough to be placed in each control room for applications from mix auditioning to final mastering. In broadcast studios, it may be used with "live" voice to Increase average modulation level or station "loudness". It will also provide enhancement and special effects in the production of commercials. Musicians, performers and recordlng-enthusiasts familiar with the sound of "typical" spring reverberation units, will find the BX 5 an affordable addition to their equipment which far surpasses the sound heretofore available in this price range. The BX 5 has a number of features in common with the AKG BX 20, BX 15 and BX 10 Reverberation Units: o Uses Torsional Transmission Line principle (patented) o High density of resonant frequencies o High pulse density to duplicate the many sound paths of naturally reverberant environments o High degree of statistical diffusion in both frequency and time domains o Linear frequency response for maximum range of applications o Precise duplication of natural room reverberation effects o Adjustable input sensitivity o Built-in limiter to prevent overdriving of reverb input o Built-in reverb/dry signal mixing o No acoustic feedback ... even when placed close to monitor loudspeakers o No special mounting or isolation required for installation
