LX480 Dual-Engine Reverb

Algorithms – Plate/Room

The Plate/Room algorithm has a higher initial reverb density when compared to the Hall algorithm.

In a larger space like a hall, the echoes are more discrete at the beginning of the reverb and as the reverb builds, the echo density also increases. With smaller rooms and plate reverbs, there is a much higher initial “echo density.”

The density buildup is much faster and there is slightly more resonance in the reverb tail because of the tuning. This is what makes this algorithm sound more like a tight room or a metallic plate.

The Plate/Room Algorithm Sound

The strength of this algorithm lies in its versatility.

With this higher density, you can create a wide range of reverb sounds.

You can create very natural and realistic smaller rooms to add the impression of a space where a particular sound was recorded for authentic liveliness. This can color the original sound source and completely change the way it is perceived.

Or you can recreate the incredibly distinctive bright and explosive attack and smooth sizeless decay of a reverb plate to add excitement or length to specific elements in your mix.

In addition to this dense reverb tail, you can also add early reflection clusters, which offer the sound a sense of first reflections which also add to the dry sound's coloration.

With Relab’s Deep Machine Learning Technology, not only have we recreated a sample-accurate emulation of the original Plate/Room algorithm, but we’ve also added additional features so you can have an authentic 480 Plate/Room reverb, plus the ability to create more vintage or more modern reverb sounds.

Get Full Access To Additional Early Reflections Not Available In The Hardware

The original hardware had limited DSP power, so the reverb designer had to remove some of the early reflection taps in the Plate/Room algorithm. This was to ensure there was enough processing power for the diffusion module (which is denser than the diffusion module found in the Hall algorithm).

By taking advantage of modern native processing capabilities, we’ve finally removed this limitation in the LX480, to make all six early reflection delay taps available, as originally intended.
