Ursa Major Space Station SST-282 (Used)
The Ursa Major Space Station SST-282 is an advanced signal processor that transforms a mono source into a new, stereo output signal using time delay techniques. Unlike traditional delay units, the SST-282 offers eight Audition Delay Taps for listening and others for synthesizing reverberation and echo. It can be compared to a special multi-head tape recorder with a 255ms long loop of tape.
The Audition Delay Taps correspond to the SST-282’s digital memory and can be re-positioned in any of the 16 pre-programmed patterns. The user has continuous control over the Echo tap, which can vary from 1 to 255ms, creating the traditional effects of tape loops.
The Ursa Major Space Station has a 9-input/stereo output mixer for the Audition Delay Taps and the direct signal. Taps are fed to the left and right summing amplifiers, allowing control over the proportion of direct to reverberant sound in the output and the amount of early-arriving vs. later-arriving reverberation.
An equalizer is placed in the circuit to attenuate the high and/or low frequencies for simulating rooms with more absorbent walls or smaller volumes. The Medium program provides for normal build-up and smooth decay of reverberation, while the Long program gives a slower build-up and a longer decay time, as in a larger acoustic space.
The processor’s effects include four programs using semi-randomly chosen delays spaced to sound like the early reflections of rooms. The maximum delay time varies between programs, from about 70ms in Room I to 255ms in Room 4. The smaller rooms are suitable for use with the Medium Reverb program, while the larger rooms offer a more spacious sound and are normally used with the Long Reverb program.
The Audition Delay programs can also be used without feedback to modify sounds by simply adding pure or multiple delays. These programs are ideal for general-purpose doubling and loudness enhancement or creating multiple abrupt-ending echoes.
