Setting Audio Levels
1. Turn Alex INPUTand OUTPUT controls
all the way down (fully counter-clockwise).
2. Connect Alex inputs to an audio source,
and outputs to an amplifier or mixer.
3. Apply an input signal at a level that you
typically use.
4. While sending audio to Alex, gradually
turn up the INPUT control until the Input
Status LED* lights green. Continue to
advance INPUT until the LED lights red
on only the loudest peaks. If the LED is
continuously red, turn the INPUT control
down.
5. If Alex is using a console's sends and
returns, set the MIX control fully clockwise (100% wet). If you are using an
instrument amplifier, start with MIX set
halfway up.

6. Gradually increase the setting of the
OUTPUT control until the audio level
from the amplifier or mixer is approximately the same as when Alex is bypassed.
* The Input Status LED is off when the incoming
signal is low; it lights to indicate acceptable levels
(6dB to 30dB below overload). The LED lights red
when the signal approaches overload. Acceptable
signals will trigger red flashes only on peaks.

A dual-function footswitch is provided with
your unit, along with a set of labels to identify
footswitch functionality.
Presets and Parameters
Alex front panel operation is simple and
straightforward. Effect selection, editing,
store, and clear functions are easily accomplished with dedicated knobs and buttons.
This section describes all of these basic
functions, as well as using footswitches to
step through registers and register chains.
The Presets
Alex is loaded with 16 permanent presets,
designed to give you the following effects:
Hall and Rooms (1-6) range from large natu-
ral-sounding spaces with the spread, attack
and build of a concert hall, to small rooms
with sudden attacks and the coloration characteristics of tight, intimate spaces. In addition to general instrumental and vocal applications, halls are a good choice for giving
separately recorded tracks the sense of belonging to the same performance.
Inverse (7) is similar to a gated reverb,
except that the initial portion of the reverb
envelope builds up before the sharp reverberation cut-off.
Gate (8) has a fairly constant sound with no
decay until the reverberation is cut off abruptly.
Inverse and Gate are both excellent effects
for percussion — particularly for snare drum.
Plates (9-12) mimic the sound of metal plates,
with high initial diffusion and a relatively
bright, colored sound. Plates are effective on
a variety of percussion instruments, as well
as on horns and voice. They are designed to
be heard as part of the music, thickening and
fattening the source material.
Chorus (13) is a 6-voice stereo chorus with
echo. Controls are provided for echo delay
and recirculation. Great on guitars and voices.
6
Flange (14) is a stereo flange with control of
resonance and the depth and speed of the
flange.
Echo (15) Digital audio's most basic effect.
Try it on everything.
Delays (16) is a 4-tap bouncing delay. The
bounce goes back and forth between left and
right outputs.
Each of the presets contains a unique
version of the 3 parameters; DECAY, DELAY and FX LVL. The parameters of each
preset are available for front panel adjustment along their entire range, allowing you to
create hundreds of variations of each effect.
Presets cannot be erased or overwritten
by parameter changes; the original version
will always be restored. If you make changes
to a preset and want to save the changes as
a custom effect, you must store your new
version in one of Alex’s 16 registers.
About the Parameters
Each of the 16 presets in Alex consists
of a unique combination of as many as 32
different parameters. These fixed parameters determine the type of preset — hall,
room, plate, etc. that you will hear when you
turn the REGISTER/PRESET knob.
For each preset, several parameters
have been made available for front panel
control through the DECAY, DELAY and FX
LVL controls.
In Halls and Rooms (1-6), and in the
Plate presets (9-12), DECAY sets the nominal reverberation decay time for a predetermined room size which is unique to each
preset.
In the Inverse and Gate presets (7-8 ),
DECAY changes both the size and the character of the program, while DELAY varies the
predelay before the gated effect. (Note that
changing the setting of DECAY in either of
these presets will briefly mute the effect.)
In Chorus (13), Echo (15) and Delays
(16), DECAY controls recirculation. In the
Flange preset (14), DECAY controls flange
resonance.
DELAY generally sets the amount of
predelay (the length of time between the
input of signal and the onset of reverberation). The range of this control varies with the
type of preset.
In Chorus and Echo, DELAY controls
the echo delay. In Flange, it controls the
depth of the flange effect. In Delays, it controls the delay time for the first of four equally
spaced delay taps.
In each preset, FX LVL sets the level of
the effects being added to the signal.
7
Note that the setting of the MIX control is
very important with several of the presets. In
the Inverse and Gate presets, MIX allows
you to set up anything from a subtle thickening or enhancement, to a solid wall of reverb.
In the Chorus and Flange presets, MIX should
be set higher than 50% wet to get rich chorus
and flange effects.

When you change between register and
preset modes, you will always recall the last
preset or register loaded, in whatever state
you left it.
Editing an Effect
For each preset, three parameters have
been made available for front panel control
through the DECAY, DECAY, and FX LVL
controls. Control over these parameters is
simple — press PARAMETER/LEARN to
select a parameter, then adjust it with the
VALUE knob. All parameter settings made
from the front panel can be stored with the
effect.
The PARAMETER button cycles the selection
of DECAY, DELAY and FX LVL. A lit LED
indicates the currently selected parameter.
The VALUE knob is always active, and will
adjust whichever parameter is indicated by
the display LEDs. The first turn of VALUE will
display the current parameter setting. Subsequent adjustments will increment or decrement parameter values along their entire
range (1-16).
Turn VALUE to adjust the selected parameter.
The display will show parameter values while the
knob is being turned. A decimal point in the
display indicates changes have been made
since the last store operation.

The decimal point on the display will light

made with VALUE, the display will revert to
showing the number of the currently running
effect. The edit indicator will remain on until
the effect is stored, or until changes are lost
by selecting another effect with the REGISTER/PRESET knob.
Performing an Edit Compare
If you do not perform a store operation,
changes made to effects will be lost as soon
as another effect
(preset or register) is selected. Changing
between
ever, will not erase your changes. This provides an edit compare capability which allows you to toggle back and forth between an
effect you are working on and the original
version. For example:
preset and register modes, how-
within
the same mode
1. Select a preset and store a copy of it in
any register.
2. Make any changes you want to either the
preset or the register.
3. Compare your new effect to the original
version simply by pressing the REGISTER/PRESET button.
4. Use the REGISTER/PRESET button to
toggle back and forth as many times as
you like between the original effect and
the new version, making changes as desired.
12
When you are satisfied with the effect,
perform a store operation to any register you
want using the procedure described on the
following page.
Storing an Effect
Alex presets cannot be erased or overwritten by parameter changes; the original
version will always be restored when loaded.
If you make changes to a preset and want to
save the changes as a custom effect, you
must store your new versions into registers.
When first shipped, Alex has a duplicate
set of the presets loaded into the registers.
Although these are grouped into different
effect types (halls, plates, etc.) there is no
need to maintain this format. You can, for
example, overwrite a gate effect with a chorus effect, or a plate with a hall.
To store the currently running effect:
1. Press STORE.
2. If you were in preset mode, the register
LED will go on, indicating that Alex has
automatically switched to register mode
— selecting whatever register is indicated by the position of the REGISTER/
PRESET knob. The plus sign (+) on the
display will light to indicate that the store
function is armed.
3. Releasing STORE will store the currently
running effect into the register indicated
on the display, overwriting the effect previously stored there. The display will flash
briefly to indicate the store operation was
successful.
13
4. Store operations are executed on release of the STORE button. If you want
to store to a different register, or to a
different register bank, than the one
displayed, turn the REGISTER/PRESET knob to the register number you
before
want
releasing STORE.
Using Footswitches
A dual footswitch can be connected to
Alex's rear-panel footswitch jack. Refer to
the diagram shown in
tions
.
Rear panel Connec-
Bypass
A footswitch can be used to bypass effects. When active, a "P" (byPass) appears
on the display. The + and – symbols, and the
parameter LED are turned off. In this state
everything is bypassed: effect select, register increment, parameter select and adjustment, etc.
Stepping through the Registers
You can use a footswitch to step through
the registers. The footswitch will increment
continuously up to register 16 then wrap
back to register 1 (or the first uncleared
register). If you are in preset mode, the first
click of the switch will automatically switch
you into register mode, loading whatever
register is indicated by the position of the
REGISTER/PRESET knob; subsequent
clicks will increment from that point on.
Clearing Registers
Aex has a clear function which allows the
use of footswitches to link effects in a variety
of useful ways. Clearing a register does not
erase the contents of a register pair. It clears
a space in the register sequence so that the
register is skipped in any effect sequence
you create.
To clear a register...
1. Briefly press STORE/CLEAR until a mi-
nus sign (-) is displayed.
2. Press and hold STORE/CLEAR. If you
were in preset mode, the register LED will
go on, indicating that Alex has automati-
14
cally switched to register mode — selecting whatever register is indicated by the
position of the REGISTER/PRESET
knob. The "–" symbol in the display will
flash, indicating that the CLEAR function
is armed.
3. Releasing STORE/CLEAR will clear the
displayed register. The display will flash
briefly to indicate the clear was successful. (The ID number of any cleared register flashes when selected with the REGISTER/PRESET knob.)
To restore a cleared register, simply repeat the clear operation with the "+" displayed.
Note using a footswitch to step through registers will
cause a discrepancy between the REGISTER/PRESET knob setting and the display (which will show the
number of the register that is actually running.)

Skipping Registers and
Creating Chains
Alex’s clear function allows you to use a
footswitch to
a sequence, or to create register
Skipping allows you to create a specific
sequence of effects. If, for example, you
want to use a series of 8 effects, simply clear
the 8 unwanted registers and turn the REGISTER/PRESET knob to 1. Now, the
footswitch will increment through the registers, passing over the cleared registers without requiring you to step through them.
Turning the REGISTER/PRESET knob to
any position other than 1, will set up register
chains which use cleared registers as loop
points.
Skip and chain functions are illustrated to
the left.
