Yamaha FX900 - Manual (Page 10)

4. The Controls: A Quick Operation Guide
0 Power Switch
Press once to turn the FX900 on, and a second time to
turn the power off. When the power is turned on, a title
and copyright notice will appear on the display panel for
a few seconds before operation actually begins.
0 Input Jack
Plug your guitar or other mono signal source in here or
into the INPUT LyMONO jack provided on the rear panel
(see "3. INPUT R & L/MONO Jacks" in the "4.
Connections: Basic System Setup" section). All input
jacks are standard 1/4" phone jacks.
0 INPUT LEVEL Control with L and R Level Indicators
For the optimum input level setting, play your source at
the highest level it will be played in actual use, and
adjust the INPUT LEVEL control so that all segments in
the level indicators except the highest segment (3) light
most of the time. The highest segment may light
occasionally on brief high-level peaks. The highest
segment features a 1-second peak-hold function.
0 LED MEMORY Number Display
Indicates the selected program number — 0 through 99.
Whether the selected program is in the PRESET or
USER memory is indicated by the PRESET and USER
LEDs, described below.
0 PRESET and USER Indicators
These LEDs indicate whether the PRESET ROM
memory area or the USER RAM memory area is
selected. Selection is accomplished via the
[USER/PRESET] key, described below.
[See page 11 for further details]
0 Liquid Crystal Display Panel
This is the FX900's main "information center," providing
all information necessary for effect program selection,
programming and utility control.
© EFFECT ON Keys — [DYN], [REV1], [MOD], [REV2]
These keys are used to turn the corresponding effect
group ON (indicator lit) or OFF (indicator out).
[See page 12 for further details!
0
[ALG] Key
When the [ALG] (algorithm) key is pressed and lit, the
[DATA ENTRY] control or
[A]
and
[T]
keys can be used
to select a new algorithm for the currently selected effect
program. In the algorithm selection mode it is also
possible to assign different effects to the various
algorithm blocks by moving the cursor to the desired
block using the cursor [◄] and [ ►] keys, and then by
using the
[A]
and
[T]
keys to select a new effect. Press
the [ALG] key a second time so that its indicator goes
out to exit the algorithm selection mode.
fSee page 13 for further details!
0
Algorithm Type Indicators
These five indicators and the associated algorithm
symbols indicate which of the FX900's five basic
algorithm types is used in the currently selected effect.
[See page 13 for further details]
(0) EDIT Keys — [DYN], [REV1], [MOD], [REV2]
These keys provide access to the editable parameters of
the effect currently in use in the corresponding effect
group. Most effects have several "pages" of parameters
that can be accessed by repeatedly pressing the
corresponding EDIT key.
fSee page 17 for further details!
dD [FLIP] Key
The [FLIP] key is used to reverse the positions of any
two effect groups in the current algorithm, allowing the
various effect groups to be placed anywhere in the
algorithm.
fSee page 15 for further details!
(g) [DATA ENTRY] Control
The [DATA ENTRY] control can be used fast selection of
programs, algorithm numbers, effects, and parameter
values when in the corresponding modes. In many
cases you might find it most efficient to use the [DATA
ENTRY] control for quick coarse adjustment, and then
use the data entry
[A]
and
[T]
keys (described next) for
fine stepwise control. Rotate the [DATA ENTRY] control
clockwise to increase the number or value, and counter­
clockwise to decrease.
