Rt Hi Cut; Rthc Damping; Spin And Wander; Infinite - Lexicon PCM NATIVE ROOM Owner's Manual

RT Hi Cut

This parameter, also known as Hicut or RTHC is a low-pass filter in the recirculating part of the
reverb. It represents a frequency above which the tail dies away more quickly. In some ways, it
represents the opposite end of the scale from BassRT, and may be considered an analog of air
absorption. It is also closely tied to the RTHC Damping parameter.

RTHC Damping

The damping parameter is closely tied to the RTHC parameter. It controls the strength of the
hi frequency absorption and has three values: Light, Normal, and Heavy. The Normal value
gives filter response identical to previous Lexicon reverbs. The other values should be self-
®
descriptive.

Spin and Wander

These two parameters control randomization effects within the reverb. Randomization is
used to control the spectral purity of the reverb. It can also, at some settings, create a more
noticeable modulation effect. Artificial reverbs sometimes create audible artifacts with some
types of signals. For example, a voiceover in a very small room might sound a little metallic.
Randomization works to minimize these effects and remove the sense of ringiness.
Spin controls the rate of randomization. In most cases, values between 1–2 Hz are appropriate.
Typically, these values should be smaller for plates and chambers or for very small rooms. But it's
always best to listen with the material you're using.
Wander controls the amount by which various delay values may be modulated, or the maximum
size of randomizer steps, and is expressed in a time value (typically milliseconds).

Infinite

This parameter captures the reverb tail as an infinite loop. This may be useful in music, where
a note or chord can be extended. It is also useful in post-production for creating ambience
backgrounds.
