WELCOME
Congratulations on your recent purchase of a new Harbinger LvL Series mixer. They are the perfect choice for bands
or individual musicians who are looking for great-sounding mixes, live performance durability and audio specs that
studio users demand.
To get the most out of your new mixer, we suggest that you read through this entire manual at least once, then refer
back to it as needed.

QUICK START
STUDIO QUICK START – PLUG IN A MICROPHONE AND HEAR IT THROUGH YOUR POWERED STUDIO MONITORS
Before we go through each feature on the mixer, we'll show a few
common setups so that you can begin using your mixer right away.
In the first example, we’re going to connect a microphone and listen
to it through powered studio monitors. Be sure to follow the direc-
tions so that you don’t hear loud feedback through your speakers!
1. Turn the CNTL RM|PH knob (under the effects) all the
way down, and the GAIN control on channel 1 (top left) all the
way down.
2. Plug your powered studio monitors into the CNTL RM OUT left
and right. Switch them on if you need to. (You can also follow
this example using headphones.)
3. Turn the LEVEL control on channel 1 up about half way.
4. Plug your microphone into the MIC input on channel 1.
5. If you’re using a condenser microphone, switch on the
PHANTOM POWER function (top right). If you’re using a
dynamic mic, or don’t know which type you’re using, leave
phantom power off.
6. Turn the MAIN MIX fader up to 0 (¾ of the way up).
7. Turn the GAIN control on channel 1 up about ½ way. If the
PEAK light flashes red, turn the gain back down a bit.
8. Slowly turn up the control room level (CNTL RM|PH) while
speaking into the microphone.
You should hear your voice through the speakers. Don’t hear
anything? Here are a few things to check:
• Are your speakers on? Are their level controls turned up?
• Do you need to switch phantom power on? Look at the mark-
ings on your microphone. If it says “condenser” then Phantom
Power should be switched on. If it says “dynamic” then leave
it off, although phantom power won't damage a dynamic mic.
• Are the level and gain knobs turned up on channel 1? Are the
Main Mix and Control Room levels turned up?
• If you only plugged in one speaker, make sure that the PAN
control is in the center.
• If the meters above Main Mix are moving, then your problem is
with the speakers. If the meters aren’t moving, something isn’t set
correctly on the mixer.
ADD REVERB
Now that we have signal running through the mixer, let’s try out the
effects. Picking up where we left off above:
1. Turn the PRESET knob to #5, “RV Plate.”
2. Turn up the FX RETURN knob about ½ way up.
3. Turn up the FX knob on the input channel and speak through the
microphone. You should see the green light next to the preset
knob light up and hear reverb on your voice.
4. Turn the Preset knob to hear the other presets.
PLAY BACK FROM YOUR COMPUTER OR
PORTABLE DEVICE
Next, we're going to play back from a line level device like a
computer, smartphone, keyboard, or mobile device.
1. If still set up as above, turn down the LEVEL control on channel
1. Keep the Main Mix and Control Room levels up.
2. Turn down the Level control for stereo channel 9-10.
3. Plug your computer, smartphone, keyboard, or mobile device
into the LINE INPUT for channels 9 and 10. You'll need ¼"
cables, either balanced or unbalanced will work.
4. Turn up the Level for channels 9-10 .

LIVE SOUND QUICK START – PLUG IN A MICROPHONE AND HEAR IT THROUGH YOUR PA SPEAKERS
Here is a typical live sound setup using two microphones, a stereo
PA, and an on-stage floor monitor.
1. Turn the MAIN MIX fader (bottom right) all the way down,
and the GAIN control on channels 1 and 2 (top left) all the
way down.
2. Plug your speakers into the MAIN OUT left and right. Switch
on the power amp or your powered speakers.
3. Turn the LEVEL control on channel 1 up about half way.
4. Plug a microphone into the MIC inputs on channels 1 and 2.
5. If you’re using a condenser microphone, switch on the
PHANTOM POWER function (top right). If you’re using a
dynamic mic, or don’t know which type you’re using, leave
phantom power off.
6. Turn the MAIN MIX fader up to 0 (¾ of the way up).
7. Slowly turn the GAIN control on channel 1 up to about ½
way. Watch the meters above the main fader. If they go up
to 0, or if the PEAK light flashes red on your channel, turn the
gain back down a bit.
8. Slowly turn up the GAIN on channel 2.
9. Switch on the power amp for your stage monitor or your
powered stage monitor. Turn up the AUX knob on any channel
you want to hear on stage.
Remember that the more microphones and speakers you use, the
more possibilities there are for feedback.

INPUT TYPES
This chapter will review the types of inputs on the L1402FX-USB mixer and explain each of their features.
CHANNELS 1-8: MIC/LINE INPUTS
MICROPHONE INPUT (MIC)
This XLR connector will accept virtually any professional microphone.
It is designed for microphone level signals. If you have a device that
plugs into the wall and has an XLR output (like a mic pre/channel
strip, guitar multi effects processor, computer interface), you should
get an XLR-to-¼" TRS cable and plug it into the line input (below).
Some microphones, mostly condenser mics, need phantom power to
operate. Switch on phantom power on the right side of the mixer. If
you're unsure if your mic needs phantom power, check the instruc-
tions or the manufacturer's website for information. Phantom power
should not hurt most microphones, except for very old or damaged
ribbon microphones.
Use the microphone preamp's gain control (explained below) to
bring the microphone up to a high enough level to use with the mixer.
LINE INPUT (LINE)
This ¼" input is designed for line-level signals. It accepts either
balanced (TRS) or unbalanced (TS) cables. The level of this input is
also controlled by the gain control, explained below.
Do not use both the microphone and line inputs on the same channel.
The mixer will distort and the noise level will go up.
The line input is not designed to accept an instrument-level signal,
such as the output from an electric or acoustic guitar or bass. If you
want to plug your instrument into the mixer, we suggest a direct
box (also called a DI box). Plug your instrument into the direct box,
then plug the output of the direct box into the microphone input of
the mixer.
GAIN
Gain controls the level of the microphone or line level signal plugged
into the mixer. If the gain is set too low, the output signal will be noisy
when you turn it up at the level control. If gain is set too high, it
will distort.
For best performance, set the gain while looking at the meters. Turn
the Level control so that it's facing straight up. Then turn the gain up
until you see the first or second lights on the meter. Don't set it too
high – although you might not hear distortion when playing by itself,
when all of the channels are playing at that level they may add
together and distort the mixer.
Sidebar: "Why are there two volume controls?"
The Gain and Level controls work together to get the best
performance out of the mixer. A quiet signal may need
more gain than a loud guitar amp going into a sensitive
microphone. Set the gain so that the level on each channel
is roughly the same, then use the Level controls to set the
balance that you want in your mix.
EQ HI
The high EQ control is a shelving EQ. What this means is that it
boosts or cuts from 12kHz and everything above that. Turn it up to
bring out the breath of a vocal or the high overtones of the cymbals.
Turn it down to reduce finger squeaks on a guitar or bass.
EQ MID
The mid EQ is a peaking EQ, centered at 2.5kHz. This boosts or cuts
the high midrange of your signal. You might turn it up if your vocal
isn't cutting through the mix, or turn it down if a percussion part is
too harsh.

L1402FX -USB Owner's Manual
EQ LOW
This low EQ boosts or cuts everything from 80Hz or below. You
might bring it up for more bottom out of your kick or bass guitar, and
turn it down to reduce rumble from a vocal or wind instrument.
HPF
The HPF is a High Pass Filter, centered at 75Hz. This means that it
cuts virtually everything below 75Hz. It can be useful for reducing
rumble or muddy low tones from an instrument, or as a way to
reduce hum in a channel. Try switching on the HPF and boosting the
Low EQ for some interesting sounds.
AUX SENDS
The Aux send is separate bus on the L1402FX-USB mixer. This means
that you can have a different mix on the aux bus than you do on the
main outputs. This comes in handy in a few scenarios:
• Sending different amounts to the effects section, so that some
instruments have more reverb than others
• Setting up a headphone mix, so that a recording musician can
hear exactly what they want while you listen to your own mix
• Creating a monitor mix on stage, so that band members can hear
what they need to perform while you mix for the rest of the club
L1402FX-USB features one pre and one post fader aux bus. The pre-
fader aux bus will send signal to the aux send output regardless of
where the level control is set.
The aux send can be sent to different parts of the mixer, depending
on the application. It always shows up at the Aux Send output of the
mixer, and you might plug that into the input of a stage monitor or
external effects processor.
Finally, you can send it to the Control Room and headphone outputs
by pressing the "Aux Send To Phones" button, next to the Control
Room/Phones level control. This allows a musician to hear their own
mix while recording with headphones.
If you would like to listen to a different mix through the Control Room
than your artist on headphones, you will need to plug the Aux out into
a headphone amplifier for the artist while you monitor the main mix.
There are two Aux sends on the L1402FX-USB Mixer. The first aux
send is routed for external effects or monitor setups. The second aux
send is routed from an input channel to the internal effects of the mixer.
This gives you the flexibility of having both two aux sends for an input
channel (monitoring and effects routing). The first aux send is pre-fader
which means the channel input fader will not affect the signal going
into the first aux bus. The second aux send is post fader, which means
the input channel fader setting will affect the signal going into the
internal effects.
PAN
The Pan control moves the signal between the left and right outputs.
When turned fully to the left, that channel will only show up on the
left main output. When turned to the center, it will be sent in equal
volume to the left and right outputs. Turned fully to the right, you will
only hear it through the right output.
Tip: You can use the pan control to create two mono mixes
from the L1402FX-USB. This might be more useful than a
stereo mix in a large club, house of worship, conference
room, or other special application.
PEAK
The Peak LED lights up when the level coming into that channel is too
loud. If you see this light flash, turn that channel's Gain control down
and the Level control up.
CHANNELS 9-12: STEREO LINE INPUTS
LEFT/MONO INPUT
This ¼" input expects a line level signal. It accepts either balanced
(TRS) or unbalanced (TS) ¼" cables. If only the Left/Mono input
is used on a channel, that signal will be sent to the left and right
outputs. (If the Right input is also used, this input will be sent to the
left output.)
RIGHT INPUT
As above, this is a line level input, either balanced or unbalanced. It
is sent to the right output.
+4/–10 SWITCH
This switch sets the sensitivity for the channel. It's similar to the gain
control, but only has two settings. Generally speaking, if your device
has balanced outputs you should use the +4 setting. If your device
has unbalanced outputs, use the –10 setting.

AUX SEND
This sends the channel to the aux bus. See the previous section for
more information.
BALANCE (BAL)
The Balance knob has a similar effect to the pan control explained
in the previous section. But the Balance control just turns down one
input or the other. As you turn Balance to the right, the signal coming
into the Left/Mono input gets softer. This allows you to control the
panning in your mix without collapsing the stereo width of the input.
LEVEL
This controls the level of the channel going to the Main Outs. See the
previous section for more information.
2TK INPUT
The 2TK Inputs are a pair of unbalanced RCA phono line inputs.
They can be used for a variety of applications:
• Monitoring a mixdown recorder. Since these inputs aren't sent
to the Main Outputs, there is no chance of a feedback loop.
• Playing an MP3 player through the PA between band sets,
muting all microphones
• Sending a signal to the headphone outputs but not to the main
outputs. You might plug a set of outputs from a computer inter-
face into these inputs, so that the metronome click can be sent
to the headphones but not the main out.
There are two buttons that control where these inputs are heard. One
is To Mix and the other is To Phones (Ctrl Room.)
When TO MIX is switched on, all of the inputs are muted except for
the 2TK input. All that you will hear from the L/R outputs is what is
playing into the 2TK input. You might use this in the example above
to play audio from a mobile device to the PA between sets.
Pressing TO PHONES/CONTROL ROOM means that only the 2TK
input is heard through the Control Room and Phones outputs. This
is useful if you are recording the mix and only want to hear what
is coming back from the recorder. This ensures that the recorder is
getting the mix that you expect to hear. It also allows you to monitor
the recorder output without creating a feedback loop in the speakers.
OUTPUT TYPES
This chapter explains each of the outputs on the Harbinger L1402FX-USB mixer and their level controls.
MAIN OUTS
The Main Outs are line outputs. They will work with either balanced
or unbalanced cables. The Main Mix fader controls the level of the
Main Outputs. You might plug the main outs into a PA amplifier or a
mixdown recorder.
All of the channels should show up at the Main outputs. If they don't,
make sure that the "2TK to Mix" button isn't pushed.
CONTROL ROOM OUTPUTS (CTRL RM OUT)
The Control Room Outputs are a separate set of outputs for the
mixer. In a home studio, you might plug these into a set of powered
studio monitors. The Ctrl Rm|Ph knob controls the level going to the
control room outputs (and the headphones.)
There are three sources that can be sent to the Control Room
Outputs. Usually, you listen to the same mix that's coming out of the
Main Outs. If the 2TK to Phones (Ctrl Room) button is pressed, only
the 2TK input will be heard through the Control Room outputs.
If the Aux to Phones (Ctrl Rm) is pressed down, the aux send will be
heard through the Control Room outputs. This can be useful when
preparing a headphone mix for an artist.
PHONES
This is a headphone-level output. It is designed to drive a pair of
headphones with a balanced ¼" connector. If your headphones
have a 1/8" stereo jack, you will need an adapter to plug them into
the mixer (included with most professional headphones.)
Note that the headphones and the control room outputs are linked
– both the mix and level. If you press 2TK to Phones (Ctrl Room), the
2TK input will be sent to both the control room outs and the head-
phones. If you turn the control room level all the way down, there will
be no signal in the headphones.
AUX SEND
This jack sends the aux bus out of the mixer. Turn up the Aux knob on
any channel to send it to the Aux Send output. See page 9 for more
information about the Aux Send.
2TK OUTPUT
This is a pair of unbalanced line level outputs. They are just a copy
of the Main Outputs. If you turn the Main Mix fader down, the level
is also reduced here.

EFFECTS SECTION
The Harbinger L1402FX-USB includes a great-sounding digital effects processor. This chapter explains how to use it.
PRESET
The L1402FX-USB Effects Processor has 16 presets. Each of these is
a different effect type. The preset names are listed on the top of the
mixer. They are explained in further detail below.
VARIABLE PARAMETER
This knob changes the character of the effect depending on the
effect type. It either changes the length of a reverb, the feedback/
repeat amount of a delay, or the depth of a modulation effect. See
the preset descriptions below for more information on how this
control works.
TAP
On effects presets with delay, press this button twice to set the
delay time. This is useful for setting the delay time in tempo with the
music. If you want a quarter note delay, press the Tap button on
two successive beats of the music and the delay time will jump to
that tempo.
SIGNAL/CLIP LEDS
These show the level going to the input of the effects processor.
When you send a channel to the effects processor, using the FX
knob, you should see the green Sgn light turn on. If the level gets
too high, you'll see the red Clip LED turn on. If this happens, turn
down the Aux 2 Send knobs on each channel to avoid distorting
the effects.
EFFECT PRESET CHART
The chart below describes the presets and what the Variable and Tap controls do for each one.
Preset Name Variable Paramenter Tap Control Description
1 Flanger Depth, from low to deep – Classic stereo flanger with a slow sweep
2 Chorus Depth, from low to deep – Chorus/ensemble effect with short delays
3 Delay-M Feedback, from single repeat to long
repeating echoes Delay Time Simple mono delay, great for vocals and guitars
4 Delay-PP Feedback, from single repeat to long echo Delay Time Stereo "Ping Pong" delay that jumps from left to right

TO PLAYBACK AUDIO
1. Connect your computer to the mixer with a USB cable. Your
computer should see the mixer as a device labeled "Samsung
UC Audio".
2. Select the mixer to playback audio from your system
control panel.
3. Playback audio from your application.
4. Make sure the CTRM/MAIN button is down near the Jacks that
say CTRL RM OUT.
5. The audio is routing to the main outputs through Aux inputs,
which means the volume control is controlled by the main fader
if the "To Mix" button is depressed (next to the RCA jacks for
AUX). The same case for Control Room.
• Are the Gain and Level knobs turned up?
• Is the Main Mix fader turned up?
• Is the 2TK to Mix, 2TK to Phones, or Aux to Phones button
pressed in?
• If the mic needs phantom power, is the PHANTOM POWER
turned on? (Try it if you aren't sure.)
• Try a different microphone cable and/or microphone.
• Check the power connections, your power strip, extension
cords, etc.
You can hear everything, but it's very noisy.
• Are all of the level controls turned up very high? Try turning
those down and the gain controls up.
• Turn down the FX return. If that was the problem, try sending
more signal to the effects by turning all of the Aux knobs up.
• Try turning down channels one at a time. If there is one channel
that is contributing most of the noise, try fixing that at the
source.
You can see level on the meters, but can't hear anything through
the control room speakers.
• Is the Aux to Phones/Control Room or 2TK to Phones/Control
Room button pressed in?
• Are the monitors switched on?
• If only one output is working, try switching the left and right
outputs. If the same channel isn't working, the problem is with
the speaker.
You turned up the FX Return knob, but can't hear the effects.
• Are you sending enough level to light the Signal LED next to the
preset knob? If not then turn up the Aux knob(s).
•Are you listening to the Aux to Phones/Control Room by mistake?
•Try a different Preset or turn the Variable knob.
TO RECORD AUDIO
1. Connect your computer to the mixer with a USB cable. Your
computer should see the mixer as a device labeled "Samsung
UC Audio".
2. Select the mixer playback and record audio from your system
control panel.
3. Setup your mixer to have audio coming in as you normally would.
4. Start up your DAW application on your computer.
5. Make sure your DAW application is setup to receive audio from
the "Samsung UC Audio" (L1402FX-USB mixer)
6. Create an audio track on your mixer and enable it to record. To
avoid a feedback you can either switch the "To Mix" button to
be in the up position or disable the monitoring function in your
DAW program on the track you are recording to.
7. Perform your audio on the mixer and record the track on your
DAW application.
8. After recording you can play back the track from your computer
to the mixer to hear the playback. Be sure to turn on the
"To Mix" or "To Phones (CTRL ROOM)" button to hear the
audio playback.
TROUBLESHOOTING
In this chapter, we'll discuss common problems and their solutions, as well as who to contact if things go wrong with your mixer.
TROUBLESHOOTING MATRIX

GLOSSARY OF TERMS
BALANCED
A 3-conductor (including shield), low-impedance connection.
Balanced cables are the preferred method for hum-free intercon-
nection of a sound system for their noise-rejection characteristics.
(Also see Unbalanced.)
BUS
An output destination in a mixer. For example, the left and right
main outputs are called buses, because you can send a channel to
one or both of them.
CHANNEL
One of any number of signal paths in an audio circuit, such as
input channel, output channel, recording channel, left channel, right
channel, etc.
DECIBEL (
d B )
A term representing the ratio between different audio levels. It can
either refer to the electrical signal running through a channel or the
acoustic sound level coming from a sound source.
DELAY
Like an echo, this effect duplicates the original signal, then plays it
back at a rate you control. The rate at which these repeats occur is
the “delay time.”
EQUALIZATION
Electronic filters that adjust the level of certain frequencies. Used for
tone enhancement or to reduce extraneous sounds. Two types of
EQ shapes are Peak and Shelving, described below.
IMPEDANCE
Resistance in an electrical circuit measured in Ohms (Ω). Main-
taining proper impedance (between amplifier and speakers for
example) is important to prevent damage to the amp.
PEAK EQUALIZER CONTROL
Increase or decrease of a frequency range centered at a specific
point, resulting in an EQ curve that looks like a hill (increase) or a
valley (decrease). (Compare to Shelving Equalizer Control; see
pages 8-9 for more information.)
PHANTOM POWER
A voltage signal that runs through a microphone cable to power
condenser microphones. Harmless to microphones that don't need
it, except for very old and/or damaged ribbon microphones.
REVERB
An audio effect that emulates the echo reflections and decay time
of a large space.
SHELVING EQUALIZER CONTROL
Increase or decrease of all frequencies above or below a specific
point. (Compare to Peak Equalizer Control; see pages 8-9 for
more information.)
TRS
Acronym for Tip-Ring-Sleeve — the three parts of a three-conductor
(including shield) audio plug. TRS phone plugs are often used for
“balanced” mono connections, or stereo "unbalanced" (head-
phone) connections.
TS
Acronym for Tip-Sleeve, the two parts of an unbalanced, two-
conductor (including shield) phone plug. TS connectors are some-
times called mono or unbalanced plugs.
UNBALANCED
A two-conductor (including shield), high-impedance connection.
These are most commonly used for instrument connections and
cable runs of less than 20 feet.
XLR
The three-pin connector universally used for balanced audio
connections. A balanced connection reduces outside noise and
interference. (See Balanced above.)
