Unpacking and Inspection

Your Alesis airFX was carefully packed at the factory, and the shipping
carton was designed to protect the unit during shipping. Please retain
this container in the highly unlikely event that you need to return your
processor for servicing.

The shipping carton should contain the following items:

• airFX Processor

• Two stereo phono-to-phono cables

• This instruction manual

• Program Chart

• Power Supply, Alesis model P3

• Alesis Warranty card

Chapter 2: Connections

CHAPTER 2

It is important to register your purchase; if you have not already
filled out your warranty card and mailed it back to Alesis, please
take the time to do so now.

Basic Connections

The airFX is designed to function with a wide range of equipment,
from CD players to musical instruments. The only requirement is that
the input and output be line level (for the technically minded,
unbalanced -10 dBu).

This means that you never want to plug the powered output of
an amplifier or receiver into the airFX. These speaker-level
voltages will fry the electronics inside of the airFX.

The systems on the next few pages will give you some examples of
typical systems where the airFX is used. If you can’t apply one of
these systems to your own setup, contact Alesis or your dealer for
assistance.

AIRFX REFERENCE MANUAL 15

Connections: Chapter 2

Connecting between a CD Player and a Stereo
Receiver

The above system allows you to hear the effect of the airFX on a CD
through any stereo system. Using one of the supplied stereo RCA
(phono) cables, plug the Left and Right outputs of your CD player into
the Left and Right Inputs of the airFX. Usually, the white connector is
connected to the left side and the red connector is connected to the
right side.

Next, using the other stereo RCA cable, plug the Left and Right
outputs of the airFX into the Left and Right CD inputs of your receiver.
(Actually, any unused inputs on the receiver should work except for
“Phono” or “Record Player”.) This hookup method also works with
self-powered speaker systems instead of a stereo receiver.

If the CD doesn't have line-level RCA outputs:

The instructions above are fine for home or professional CD Players.
However, most portable CD players don’t have a pair of RCA outputs
like component CD players do. Instead, they have a 1/8” Mini jack.
This is usually labeled “Line Out”. If your CD Player doesn’t have a
Line Out, then use the Headphone output and set the Volume to about
80% or less to avoid distorting the airFX.

Many portable CD players include a cable with a 1/8” mini jack on one
side and a pair of RCA connectors on the other. You will need to
locate or purchase this cable to use a portable CD player with the
airFX. Plug the RCA connectors on this cable into the Left and Right
Inputs of the airFX. You should be able to use these instructions to
connect a game console, DVD player or video camera through the
airFX.

Although the speaker outputs of many compact stereo systems
use an RCA connector between the main outputs and the
speakers, speaker level voltages like these will distort and
possibly damage the airFX.

16 AIRFX REFERENCE MANUAL

Connecting into a DJ System

Chapter 2: Connections

This section explains how to connect the airFX into a DJ system. The
first point to mention is that the output of a turntable is not at line
level. Therefore, unlike a CD player, you can’t just connect the output
of the turntable into the airFX. You need to connect the turntable to a
phono preamp, then connect this output to the airFX.

In a DJ system, the preamp is usually built into a mixer. In the
diagram above, we first connect the two turntables into the mixer. We
then plug the Left and Right outputs of the mixer into the airFX,
making sure that these are not speaker level outputs. Next, plug the
Left and Right outputs of the airFX into the Left and Right inputs of
your power amplifier.

If your amplifier is built into the mixer, make sure you don’t plug
those speaker-level outputs into the inputs of the airFX. The
voltage levels needed to drive large DJ speakers will distort and
possibly damage the airFX.

If the amplifier is built into the mixer, there may be a “main insert” in
the mixer, designed for an EQ. If so, plug the Left and Right Insert
Sends into the inputs of the airFX and the Left and Right outputs of the
airFX into the Insert Returns.

With the setups above, you will hear the effect of the airFX on
everything that comes out of your mixer. If you have a separate
preamp for your turntable, or if you are using a CD player, you may

AIRFX REFERENCE MANUAL 17

Connections: Chapter 2

want to connect the airFX to one of the inputs to your mixer while the
other plays unaffected. To do this, connect the outputs of your preamp
or CD player into the inputs of the airFX. Then connect the outputs of
the airFX into the inputs of your mixer. Now you can mix between the
effected mix from one source to the uneffected source on another.

Mounting on a Microphone Stand

The bottom of the airFX features a threaded socket for a standard
microphone stand. This allows the unit to be mounted away from the
area where the other equipment is, so that unintended movements
won't be picked up by the Axyz controller.

When mounting on a stand, avoid tipover by:

• Using a stand with a heavy base

• Tying the input, output and power cables to the stand in several
places, especially near the base (so if someone pulls on the cord,
it pulls on the base)

• Using cords that are long enough

18 AIRFX REFERENCE MANUAL

Connecting to a Synthesizer

Chapter 2: Connections

The airFX can add great filter effects to a synthesizer. In the diagram
above, we demonstrate how the Left and Right outputs of the
synthesizer are connected to the inputs of the airFX, then the stereo
outputs of the airFX are connected to two inputs of a mixer.

The outputs of a synthesizer are usually 1/4” jacks, which means that
you’ll need to purchase an adapter cable to use the airFX. The best
choice is a cable with RCA (phono) jacks on one side and 1/4” jacks on
the other. Your Alesis dealer will almost certainly carry these cables.

AIRFX REFERENCE MANUAL 19

Connections: Chapter 2

Connecting to a Studio Mixer

The best method of connecting the airFX to a mixing console or
multitracker is to use the channel inserts. You’ll need two "insert
splitter" cables with a TRS stereo 1/4” connector on one side splitting
to two RCA connectors on the other. (Note: this is NOT a "Y" cord; the
ring is connected to one RCA and the tip to the other.) Insert the 1/4”
stereo plug into the mixer’s channel insert, connect the send plug to
the airFX’s Input and the return to the airFX’s output.

You can also use the main inserts, if your mixer has them, to use the
airFX on the entire mix, or on a group insert if you want to effect
multiple channels at once but not the entire mix.

Aux send/return: Note that in most cases, you won't connect the

airFX to an effects send and return of a mixer, the way that
many reverbs or other effect devices are. This is because when
the effect is off, the airFX still sends the "dry" signal to its
outputs. This may cause phase cancellation or other unwanted
effects if the aux return is mixed back with the original.

Mono Operation

If your source does not have stereo outputs, you can use only one side
of the airFX. Plug the mono output of your source into the Left input
of the airFX, then connect the Left output of the airFX to the
destination. If the destination is stereo, you may need a “Y-cable” to
split the one RCA jack into two RCA jacks.

20 AIRFX REFERENCE MANUAL

Selecting a Program

The Alesis airFX contains 50 programs for adding a variety of new
effects to the incoming signal. There is a list of program names printed
on the bottom of the unit, and you should have received a program
chart with the unit that describes each program.

Selecting a new program is simple:

1. Turn the program knob on the bottom left side of the airFX to select
a program number. The new program will not load right away,
allowing you to keep using one program while you find another.

AIRFX REFERENCE MANUAL 21

Performance: Chapter 3

Using the Axyz™ Controller

The airFX is the first Alesis product to use the groundbreaking Axyz
controller. This controller allows you to use your hand to control the
sound of your music in a way never before possible.

The Axyz controller works by sending a beam of invisible infrared
light out of the top of the unit. There are sensors all around the dome
which see the light when it is reflected back. By moving your hand
around the dome, you reflect the light to different sensors, and this
changes the sound of the effect.

There are three sets of sensors in the Axyz controller, they are known
as the X-axis, Y-axis, and Z-axis.

The X-axis sensor reads your hand position from left to right.

The Y-axis sensor reads your hand position from the front to the back
of the unit.

The Z-axis sensor reads how close your hand is to the sensor (up and
down).

Tip: When playing the airFX, make sure to move your hand in all

three directions. Some of the programs don’t use the Y-axis, but
most use all three.

You should hear an effect when your hand gets within 6” (15 cm) of
the Axyz controller. For a list of what each axis does to the sound, see
the Program Chart which came with your unit.

Note that ambient light can affect the sensitivity of the Axyz controller.
Make sure that you don’t sit the airFX right next to a light source or in
the sun, or you may notice that you need to move your hand closer to
hear an effect. You may also notice this if a large light is pointed
directly at the airFX when you are on stage.

22 AIRFX REFERENCE MANUAL

Effect Hold

The airFX has a function that allows you to freeze the current effect
from the airFX without needing to hold your hand in place. This
function is called Hold.

To use the Hold function:

1. Recall a program as described in the previous section. There should
be no decimal points showing in the display.

Note that there are no decimal points in the display, showing that the
effect is loaded and operational.

2. Move your hand around the Axyz controller, stopping your hand
position when you find an effect that you want to freeze.

3. Press and hold the Program knob for about one second. A decimal
point should appear in the display between the first and second
number of the program.

1.2

A decimal point has appeared between the first and second digits of the
program number, showing that the Hold function is set.

4. Move your hand away from the Axyz controller. Notice that the
effect continues as if your hand was still there.

5. To turn off the hold function and resume normal operation, press
the Program knob one more time. The decimal point should go
away and you can use the Axyz controller again to modify the
sound.

AIRFX REFERENCE MANUAL 23

Performance: Chapter 3

Effect Bypass

The effect Hold function can also be used as a Bypass. This function
turns off the Axyz controller so that the effect is not accidentally
triggered.

To use the Bypass function:

1. Recall a program as described in the previous section. There should
be no decimal points showing in the display.

Note that there are no decimal points in the display, showing that the
effect is loaded and operational.

2. Move your hand away from the Axyz controller, making sure that
the airFX isn’t affecting the sound.

3. Press and hold the Program knob for one second. A decimal point
should appear in the display between the first and second number
of the program.

1.2

A decimal point has appeared between the first and second digits of the
program number, showing that the Bypass/Hold function is set.

4. The Axyz controller should now have no effect, so moving your
hand towards the Axyz dome should not change the sound.

5. To turn off the hold function and resume normal operation, press
the Program knob one more time. The decimal point should go
away and you can use the Axyz controller again to modify the
sound.
