The 25 algorithms on the Dual FX card represent all of the possible combinations
of these effect blocks:
Gld-Hall Gld-Chmb
Band-Hall Band-Chmb
Chrs-Hall Chrs-Chmb
Res1-Hall Res1-Chmb
Res2-Hall Res2-Chmb
Each algorithm has a different combination of FX and Rvb types, but the basic
functionality of each is the same. Controls for each algorithm are arranged in a
PCM 80-type matrix. The audio parameters are identical to those in the
80. New control parameters are found in the Control row and a new Submixer
row.
The PCM 80 Dual FX card contains a built-in library of 250 preset programs that
provide not only a comprehensive array of effects configurations, but a whole
new assortment of exciting and useful sounds. As in the PCM 80, the presets are
organized into banks of 50, and functionally grouped for a wide range of
applications. Be sure to experiment with all 250 presets to get a feel for the full
range of the Dual FX capabilities. As in the PCM 80, each preset (except for the
bank X4 "Clean Slate" presets) has one or more parameters patched to the front
panel ADJUST knob, giving you instant control over the primary aspect of the
effect — without going into Edit mode.
The stereo presets in banks X0, X1 and X2 are designed to process stereo input
material. Many of these presets will maintain the stereo image of the source
while adding reverb, delay, eq, (etc.) processing. These provide particularly
powerful options for such applications as: re-mix processing, processing stereo
submixes, processing material with sources that "move" within the stereo field
and, of course, processing instruments or samples that have been recorded with
stereo miking techniques. To get the most from these presets, both inputs should
be used. (To process a mono source, send the same signal to each input).
The Mono In/Stereo Out presets in bank X2 create a stereo image from a mono
source. They can be used with only one input connected. If both inputs are
connected, you can send the signal to be processed to either input.
The Dual Mono In/Stereo Out presets in bank X3 can be used either to process
one mono source with two independent stereo effects, or to process two mono
sources— each with independent stereo effects. In general, the left input feeds
a stereo 4 voice effect (echo, chorus, flange, eq, etc.) and the right input feeds
a stereo reverb (plate, chamber, hall, etc.)
The Dual Mono In/Mono Out presets in banks X3 and X4 provide two completely
independent mono effects. The left in/out is routed through a mono 4 voice
effect. The right in/out is routed through a mono reverb. These are useful when
working with material intended for a mono mix, or for "in-line" processing with the
PCM 80 connected to channel inserts. The "Clean Slate" presets in bank X4 are
provided as a convenient starting place when you want to create a new program
from scratch. There is one clean slate preset for each of the 25 algorithms.
We hope you will find the Dual FX card easy to use, and a great extension of
the power of your PCM 80. To get the most out of the card, we suggest that you
invest the time to explore this manual. We think you'll agree that the time spent
investigating will reward you with enjoyment of the full capabilities of the card.
