front panel). The PC Remote application also allows you to

archive

pre-

sets to your computer’s hard drive (or other storage device) and to re-
store them. However, archiving a preset is not the same as saving it. Ar-
chived presets reside on a storage medium supported by your computer,
while saved presets reside in the 8300’s local non-volatile memory. You
cannot archive a preset until you have saved it. (See

To back up user pre-

sets, system files, and automation files onto your computer’s hard drive

on page 3-65.)

Note that if, for some reason, you wish to save an unmodified preset (ei-
ther Factory or user) under a new name, you must temporarily make an
arbitrary edit to that preset in order to make the

set again.

About the Processing Structures

If you want to create your own User Presets, the following detailed discussion of the
processing structures is important to understand. If you only use Factory Presets, or
if you only modify them with

, then you may still find the material inter-

esting, but you do not need to understand it to get excellent sound from the 8300.

In the 8300, a processing structure is a program that operates as a complete audio
processing system. Only one processing structure can be active at a time. Just as
there are many possible ways of configuring a processing system using analog com-
ponents (like equalizers, compressors, limiters, and clippers), the 8300’s DSP hard-
ware could realize several possible processing structures. Unlike an analog system,
where creating a complete processing system involves physically wiring its various
components together, the 8300 realizes its processing structures as a series of high-
speed mathematical computations made by Digital Signal Processing (DSP) inte-
grated circuit chips.

There are three basic structures:

Two-Band

Normal

Five-Band

and

Ultra-Low-

Latency Five-Band

. To select a structure, choose a factory preset having the desired

structure, and, if you wish, edit it to create a user preset.

Two-Band

is a purist, phase-linear structure. When correctly configured, it can be

used for protection limiting and we provide a preset that uses it for this. It is also the
basis for the

CLASSICAL-2

BAND

presets. It can have higher latency than the five-

band presets (up to 23 ms).

Optimum Five-Band

is the basic structure used for popular music in its many varia-

tions. Because it provides effective automatic re-equalization of program material, it
is also used for news, talk, and sports.

The stereo enhancer, AGC, equalizer, and “back end” clippers are common to both
Two-Band and Five-Band processing and therefore stay the same when the 8300
switches between two-band and five-band operation. However, different controls
appear in the screens containing dynamics processing controls, as appropriate for
Two-Band or Five-Band multiband compression. The meters also change functional-
ity to display the Two-Band or Five-Band gain reduction.
