The PCM 91 offers Lexicon’s highest quality reverbs in a compact, affordable package with a powerful interface which allows both easy access and a wealth of programming capabilities for the sound designer. All of the features of the acclaimed PCM 90 are included, plus full AES/EBU I/O, Dual Reverb algorithms, and presets with dynamic spatialization effects for 2-channel or surround applications (available for the PCM 90 on a PC card).

One of the stunning advances in the PCM 91 is the ability to create incredibly realistic small spaces. For both music and film sound, it is often vital to have the ambiences of a phone booth or very small drum room. In the PCM 91 you can create them with a reality never heard before from any processor other than a Lexicon.

Lexicon’s research into the physics of acoustics is embodied in the Random Hall algorithm. Echograms of real halls have dispelled the myth of pre-delay and early reflections. In actual spaces, there is no empty interval between the arrival of direct sound and the maximum reverb density filled by early reflections. Instead, ambience builds gradually, with diffuse and complex reflections that do not color the timbre of sound like fixed-delay taps.

Random Hall’s unique Shape, Size, and Spread parameters control the build-up and decay of the ambient envelope. Size determines how large the space will be. Shape controls the contour of the ambient build. At its highest settings, it provides an inverse envelope for effects and gating. Spread controls the duration of Shape, setting the build-up and sustain. Precision filters provide spectral control of reverberation time, and unique Spin and Wander parameters add random movement ensuring smooth reverberant decay.

In the PCM 91, Lexicon’s classic Concert Hall algorithm has been enhanced with Spatial EQ and a Compressor to increase its versatility. The Rich Plate algorithm provides simulated plate reverberation, as well as new variations on this classic effect. The Ambience algorithm provides effects tailored specifically to the post-production environment, permitting accurate matching of previously recorded ambience. This allows new elements to blend seamlessly, and sound effects, dialog, or music to be placed realistically at different positions in the “space.”

Each of the PCM 91 algorithms include selected tools for ambience, post-processing, and compression/expansion, as well as modulation and patching parameters common to each. Ten Dual Reverb algorithms are built-in to the PCM 91.These algorithms contain two independent reverb blocks to create superb Dual and Cascade-configured stereo reverbs, each with all the control features of the single effects.

PCM 91 Custom Controllers Control in the PCM 91 has been increased with the addition of four Custom Controllers placed on the Soft Row. These controllers consist of one or more parameters patched together, each with individual scaling values. Custom controllers effectively add four more Adjust knobs to each program.
