INTRODUCTION
Thank you for choosing one of Phonic’s many quality
compact mixers. The AM series of mixers – designed by
the ingenious engineers that have created a variety of
mixers fantastic in style and performance in the past –
displays similar prociency that previous Phonic products
have show; with more than a few renements, of course.
The AM series features full gain ranges, amazing low
distortion levels, and incredibly wide dynamic ranges, just
showing the dominance these small machines will have
in the mixing World.
We know how eager you are to get started – wanting to get
the mixer out and hook it all up is probably your number
one priority right now – but before you do, we strongly
urge you to take a look through this manual. Inside, you
will nd important facts and gures on the setup, use and
applications of your brand new mixer. If you do happen to
be one of the many people who atly refuse to read user
manuals, then we just urge you to at least glance at the
Instant Setup section. After glancing at or reading through
the manual (we applaud you if you do read the entire
manual), please store it in a place that is easy for you to
nd, because chances are there’s something you missed
the rst time around.
Features
• Two balanced mic/line inputs with 3-band EQ and lowcut
• Four stereo inputs with +4/-10 select buttons
• Post-fader AUX/EFX send on every input
• Global +48V phantom power
• CTRL RM and headphones outputs
• Peak indicators on each mono input channel
• Convenient RCA stereo I/O for MD, MP3 player
• Stereo EFX send cue for better monitoring of individual
channels
• Balanced master output with 60mm fader control
AM240D also features:
• 32/40-bit digital stereo effect processor with 16
programs and one main parameter control
GETTING STARTED
1. Ensure all power is turned off on your mixer. To totally
ensure this, the AC cable should not be connected to
the unit
2. All faders and level controls should be set at the lowest
level and all channels switched off to ensure no sound in
inadvertently sent through the outputs when the device
is switched on. All levels can be altered to acceptable
degrees after the device is turned on using the channel
setup instructions.
3. Plug any necessary equipment into the device’s various
outputs. This could include ampliers and speakers,
monitors, signal processors, and/or recording devices.
4. Plug the supplied AC cable into the AC inlet on the back
of the device and then into a power outlet of a suitable
voltage.
5. Turn the power switch on and follow the channel setup
instructions to get the most out of your equipment.
CHANNEL SETUP
1. To ensure the correct audio level of the input channel
is selected, each of the level input controls of the mixer
should be turned counter-clockwise or down as far as
they will go (which should be the -∞ mark)
2. No input other than the one being set should have any
device plugged in. This will ensure the pure signal is
used when setting channels
3. Set the level control of the channels you are setting to
the 0 dB mark.
4. Ensure the channel has a signal sent to it similar to
the signal that will be sent when in common use. For
example, if the channel is using a microphone then you
should speak or sing at the same level the performer
normally would during a performance if a guitar is
plugged into the channel, then the guitar should be
strummed as it normally would be (and so on). This
ensures levels are completely accurate and avoids
having to reset them later.
5. Set the gain so the level meter indicators the audio Is
around 0 dB.
6. This channel is now ready to be used; you can stop
making the audio signal.
7. You can repeat the same process for other channels.

MAKING CONNECTIONS
Inputs and Outputs
English
1. XLR microphone Jacks
These jacks accept typical 3-pin XLR
inputs for balanced and unbalanced
signals. They can be used in
conjunction with microphones – such
as professional condenser, dynamic
or ribbon microphones – with standard
XLR male connectors, and feature
low-noise preamplifiers, serving for
crystal clear sound replication. Each
of the AM series mixers features one
standard XLR microphone inputs for
your convenience.
NB. When these inputs are used with condenser microphones, the
Phantom Power should be activated. However, when the Phantom
Power button is engaged, single ended (unbalanced) microphones
and instruments should not be used on the mic inputs.
2. Line Inputs
This input accepts typical ¼” TRS or TS inputs, for balanced
or unbalanced signals. There are various numbers of these
inputs depending which mixer you are using. They can be
used in conjunction with various line level devices such as
keyboards, drum machines, electric guitars, and a variety
of other electric instruments.
3. Stereo Channels
Each of the AM series mixers feature a few stereo
channels thrown in for maximum exibility. Each of these
stereo channels features two ¼” TRS phone jacks, for
the addition of various line level input devices, such as
electric keyboards, guitars and external signal processors
or mixers. These stereo channels can also be used as
mono channels, where the signal from any ¼” phone jack
plugged into the left stereo input will cause the signal to
be duplicated to the right input also. This does not work
in reverse.
5. AUX / EFX Send
These ¼” TS outputs may be used to connect to an external
digital effect processor, or even an amplier and speakers
(depending on your desired settings) to the mixer.
6. Phones
This stereo output port is suited for use with headphones,
allowing monitoring of the mix. The audio level of this output
is controlled using the Phones/Control Room control.
7. 2T Record / Record Out
These outputs will accommodate RCA cables, able to be
fed to a variety of recording devices such as MP3 recorders
and laptop computers.
8. 2T Return
These RCA inputs are used to connect the mixer with
external devices, such as tape and CD players, or even
laptop computers. The received signal will be fed to either
the Main L/R or Phone mixes.
9. Control Room Outputs
These two 1/4” phone jack outputs send the signal from
the Control Room / Phones feed, the level of which is
determined by the control on the face of the mixer. This
output has extensive use. For example, it can be used to
feed active monitors for the monitoring of audio signals
within a sound booth. Alternatively it can be used as an
additional auxiliary.
4. Main L and R Outputs
These two ports will output the nal balanced line level
signal send from the main mix. The primary purpose of
these jacks is to send the main output to external devices,
which may include power ampliers (and, in-turn, a pair of
speakers), other mixers, as well as a wide range of other
possible devices (equalizers, crossovers, etcetera).

10. Power Connector
This port is for the addition of the external
power supply, allowing power to be supplied
to the mixer. Please use the power supply that
is included with the mixer only.
AM240 / AM240D
CONTROLS AND SETTINGS
Channel Controls
11. Mic/Line Gain Control
This controls the sensitivity of the input signal of the line/
microphone inputs. The gain should be adjusted to a
level that allows the maximum use of the audio, while
still maintaining the quality of the feed. This can be
accomplished by adjusting it to a level that will allow the
peak indicator occasionally illuminate. The AM240 and
AM240D feature a gain control on both channels 1 and 2,
directly below the line inputs.
12. High Frequency Control
This control is used to give a shelving boost or cut of ±15
dB to high frequency (12 kHz) sounds. This will adjust
the amount of treble included in the audio of the channel,
adding strength and crispness to sounds such as guitars,
cymbals and synthesizers.
13. Middle Frequency Control
This control is used to provide a peaking style of boost
and cut to the level of the middle frequency (2.5 kHz)
sounds at a range of ±15 dB. Changing middle frequencies
of an audio feed can be rather difcult when used in a
professional audio mix, as it is usually more desirable to cut
middle frequency sounds rather than boost them – soothing
overly harsh vocal and instrument sounds in the audio.
16. EFX Control
These controls determine the level of the current channel
that is sent to the EFX send output. This signal can be used
in conjunction with external processors or for any other
auxiliary application. The signal can then be returned from
processors via the AUX return inputs. This control is post-
fader, therefore any channels made to the corresponding
channel fader are also applied to the EFX signal.
17. +4 / -10 Switch
This switch is used to adjust the input sensitivity of the
corresponding channels, which will adapt the AM mixer to
external devices which may use different operating levels.
If the input source is -10 dBV (consumer audio level) it is
best to engage the switch, allowing the signal to be heard.
The +4 dBu mode is suitable for professional audio signals.
However if you are unsure of the source’s operating level,
we suggest leaving the switch disengaged until you test
the source’s signal. You can then engage if necessary (if
the level of the input signal is obviously too low).
English
14. Low Frequency Control
This control is used to give a shelving boost or cut of ±15
dB to low frequency (80 Hz) sounds. This will adjust the
amount of bass included in the audio of the channel, and
bring more warmth and punch to drums and bass guitars.
15. High-Pass Filter (75 Hz)
This button will activate a high-pass lter that reduces all
frequencies below 75Hz at 18 dB per octave, helping to
remove any unwanted ground noise or stage rumble.
18. Pan / Balance Controls
This alternates the degree or level of audio that the left
and right side of the main mix should receive. On mono
channels, this control will adjust the level that the left and
right should receive (pan). On a stereo channel, adjusting
the BAL control will attenuate the left or right audio signals
accordingly (balance).
19. Peak Indicator
This LED indicator will illuminate when the device hits high
peaks, 6 dB before overload occurs. It is best to adjust the
gain of the channel so that the PEAK indicator lights up
on intervals. This will ensure a greater dynamic range of
audio. The peak indicator can be found on both channels
1 and 2 of the AM240 and AM240D mixers.
20. Level Control
This control will alter the signal level that is sent from the
corresponding channel to the main mix.
AM240 / AM240D

Digital Effect Section (AM240D only)
21. Program Control
English
This rotary control allows users to select the digital effect
program of your choice. There are 16 points on the rotary
control, each of which corresponds with an effect type. See
the digital effect table for more information.
22. Parameter Control
Turning this control will adjust the one main parameter of
the selected effect. Each effect’s parameter can be found
on the digital effect table.
23. EFX “to Main” Control
This will adjust the level of the Digital Effect signal that will
be sent to the Main stereo mix.
24. EFX “to Ctrl” Button
This button is pushed to allow the signal from the Digital
Effect processor to be sent to the Control Room outputs
for monitoring purposes.
27. Phantom Power Switch
When this switch is in the on position it activates +48V of
phantom power for microphone inputs, allowing condenser
microphones to be used on these channels. On the
AM240D, the phantom power switch is located on the rear
of the mixer – beside the power switch.
NB. Phantom Power should be used in conjunction with condenser
microphones only. Do not engage Phantom Power if a condenser
microphone is not being used to avoid causing damage to the
mixer’s circuitry.
28. Control Room / Phones Control
This control is used to adjust the audio level of the phones
feed, to be sent to the Phones output. This can then be
used in conjunction with headphones or, if required, as an
auxiliary output. This control also adjusts the level sent to
the Control Room output for use in monitoring, as a side
ll, or for the addition of other external devices.
29. Main L-R Control
This control is nal level control for the main left and right
audio feed, sent to the Main L and R output.
Master Section
25. AUX Send Control (AM240 only)
This control adjust the nal level of the AUX mix (as taken
from AUX controls on each channel strip), the audio of
which is sent to the AUX send output.
26. 2T Return Controls
Push either one of the buttons in the 2T return control
section selects the destination of the 2T return signal. The
“to Main” sends the signal to the Main stereo mix, whereas
“to Ctrl Rm” button sends the signal to the Control Room/
Phones mix.

30. Level Meter
The AM series’ level meters give an accurate indication of
when audio levels of the MAIN L/R output reach certain
levels. It is suggested for the maximum use of audio to
set the various levels controls so that the uppermost LED
ashes only occasionally (and perhaps a pinch below that).
The AM240 and AM240D both feature dual 4-segment
level meters.
31. Power Indicator
The power indicator will light up when the power of the
mixer is on.
