•Power on the powered speakers connected to the LV12 or LV14’s
MAIN OUTS
SETTING LEVELS
• MICROPHONE – If you have connected a condenser microphone, press the 48V switch (the 48V LED will come on). If you have connected a dynamic
microphone, the 48V switch should be in the off position with the 48V LED off. If you experience too much “boominess” or bass in the microphone signal,
set the 80Hz HPF button to the on position. While speaking or singing into the connected microphone, slowly bring up the channel 1 GAIN control until only
the loudest input briefly triggers the channel 1 CLIP indicator LED. Reduce the GAIN control slightly from this level. Continue speaking or singing into the
connected microphone and slowly bring up the CH 1 level control to the 12 o’clock position, then slowly bring up the MAIN level control until a comfortable
listening level is achieved.
• PHONE/TABLET/LAPTOP (ANALOG CONNECTION)– Press play on the connected audio player and increase the player’s internal volume control to
maximum level. Slowly bring up the BLUETOOTH | STEREO / CH 11|12 (LV12) / CH 13|14 (LV14) level control to the 12 o’clock position, then, slowly
bring up the MAIN level control until a comfortable listening level is achieved.
• GUITAR – Make sure the channel 5|6 (LV12) or channel 7|8 (LV14) GUITAR HI-Z switch is set to the on position. While strumming the guitar, bring up the
CH 5|6 channel level control (LV12) or CH 7|8 channel level control (LV14) to the 12 o’clock position and slowly bring up the MAIN level control until a
comfortable listening level is achieved.
• COMPUTER (USB CONNECTION) - (LV14) With the computer’s sound output set to WAVE OUT USB DEVICE and with audio playing on the computer,
press the CH 11|12 USB source selection button and bring up the CH 11|12 level control to the 12 o’clock position and slowly bring up the main level control
until a comfortable listening level is achieved.
• POWERED SPEAKERS – To monitor through powered speakers, while source signal from the microphone, phone/tablet/laptop, guitar or computer is
present, slowly bring up the MAIN fader level control until a comfortable listening level is achieved.
• MONITOR SPEAKERS – To monitor through a powered stage monitor or powered speaker connected to the MON OUT, slowly turn up (clockwise) the
MON level knob in the lower right corner of the mixer to the 12 o’ clock position and then turn up the MON send level on the channels you wish to send to
the connected monitor speaker.
• HEADPHONES – Since the headphone level control is independent from the MAIN level control, first ensure that the channel level controls are set so
that ample signal is feeding the main and headphone buses. The meters should show between +3 and +5 dB with the MAIN level control at the 12 o’clock
position (LV12) or 0 dB (LV14). When this is accomplished, slowly bring up the headphone level control until a comfortable listening level is achievedcontrols
are set so that ample signal is feeding the main and headphone buses. The meters should show between +3 and +5 dB with the MAIN level control at the 12
o’clock position. When this is accomplished, slowly bring up the headphone level control until a comfortable listening level is achieved.
The mixer powers up with Bluetooth off. Press the PAIR button to initialize Bluetooth and activate pairing (the PAIR LED will flash, indicating that it is ready to pair).
The LV12 or LV14 will automatically reconnect to the previous Bluetooth audio source if it is available, and will otherwise be available for Bluetooth pairing from a
source audio device such as a smartphone.
If connecting for the first time, look for and select “Harbinger Mixer” on your Bluetooth audio source device.
The PAIR LED is lit solid when currently paired, blinking when available for pairing, and off if Bluetooth has been disabled by pressing and holding the PAIR
button, or when the mixer first powers up.
Pressing the PAIR button when a pairing is active forces any currently connected Bluetooth audio source to disconnect, and makes the mixer available for pairing.
See Bluetooth Troubleshooting section in case of difficulty.

USB WALKTHROUGH  LV14
PLAYBACK & RECORDING VIA USB
The LV14 is fully ASIO (Windows) and Core Audio (MAC) compliant audio interface and as such does not require any special driver installation.
Playback:
1. Make sure the LV14 mixer - WAVE OUT USB DEVICE is set as the audio output device within the PC’s system settings and within the DAW software
or audio player
2. Start audio playback from the DAW or audio player
3. Press the USB ROUTING TO CH 11 |12 BUTTON
4. MON SEND TO PHONES | CTRL RM button is in the up position
5. Slowly bring up the CH11|12 level control
Recording:
1. Connect all input signals to the LV14 mixer
2. Set the channel level controls and MAIN level fader so that the MAIN level meters show the mix peaking somewhere around 0 dB
3. Make sure the LV14 mixer - WAVE OUT USB DEVICE is selected as the audio input device within the PC’s system settings and within the DAW software
4. Arm the stereo DAW track and press record. The mixer’s MAIN MIX will now be recorded by the DAW
NOTE: The stereo MAIN mix output signal is the default signal feeding the USB audio output and being sent to the DAW. Playback audio from the DAW will
route to the LV14’s CH 11|12 (when the USB ROUTING TO CH 11|12 button is engaged on the LV14).
Overdubbing:
1. Make sure the LV14 mixer - WAVE OUT USB DEVICE is set as the audio input and output device within the PC’s system settings and within the DAW software
2. Reduce the LV14’s CH 11|12 level control to its minimum / full counter-clockwise position (do this for any channels you do not want recorded by the DAW)
3. While singing/strumming/drumming, bring up the channel level controls for the channels you are about to record, and watch the input level meters on your
DAW to make sure the loudest parts of the input are just below clipping.. Any signal panned hard-left will be sent out the left channel only, any channel
panned hard-right will be sent out the right channel only.
is in MON position and use the channel MON SEND CONTROLS to create a
mix of the playback and live recording tracks. You will hear both the playback tracks and the signals you are recording in the Headphones and CTRL RM
OUTS, but only the signals being sent to the MAIN mix will be recorded by the DAW.
5. Within the DAW, you will have the option to record a mono signal (splitting the L + R MAIN MIX into separate tracks) or a stereo signal. Select the
appropriate input within the DAW. Arm the DAW track and hit record.
A REAL-WORLD EXAMPLE USING THE LV14:
Tracking a Vocal and a Guitar simultaneously to a click track being generated by your DAW.
1. Within the DAW, initialize 2 separate mono tracks that will serve as destinations for the vocal and guitar signals coming from the mixer. On the vocal channel,
select the mixer’s R output, on the guitar channel, select the mixer’s L output.
2. Plug your vocal mic into XLR or TRS input of CH1 (activating the 48V Phantom Power switch if it is a condenser mic)
3. While watching the mixer’s CH1 clip indicator, sing into the microphone and set the CH1 GAIN control so that only the loudest input causes brief clipping.
Then reduce the gain slightly.
4. While watching the input level meter of the DAW’s vocal channel, adjust the mixer’s CH1 LEVEL control to get an acceptable level feeding the DAW.
The loudest input should fall just below clipping.
5. Then turn the CH1 PAN control all the way to the right
6. Plug your guitar into CH 7|8 L/mono input and engage the Hi-Z button.
7. While watching the CH 7|8 clip indicator LED, strum the guitar. When only the loudest input briefly triggers the clip LED, reduce the CH 7|8 GAIN
control slightly.
8. While watching the input level meters of the DAW’s guitar channel input, strum the guitar and bring up the mixer’s CH 7|8 LEVEL control until the loudest
input falls just below clipping.
9. Now turn the Pan control on CH 7|8 all the way to the left
10. Your DAW or audio capture software can now receive the vocal channel audio and the guitar channel audio on 2 separate tracks. Keep in mind, if the
microphone is in close proximity to the guitar, there will likely be some bleed of the guitar into the vocal channel.
11. Now in your DAW set up a channel that can play a click or guide track at the desired tempo, but do not start playing it yet
12. Set up your DAW’s audio output to WAVE OUT USB DEVICE and on the mixer press the USB Routing to CH 11|12 button
13. Set the HEADPHONE|CTRL RM SOURCE button to the MON position
14. Make sure the CH 11|12 level control is turned all the way down to the left (counter-clockwise) and slowly turn up the MON level control on CH 11|12.
15. Use the channel MON SEND CONTROLS to create a mix of the playback and live recording tracks. You will hear both the playback tracks and the signals
you are recording in the Headphones and CTRL RM OUT output, but only the signals being sent to the MAIN mix will be recorded by the DAW
16. Now when you arm a channel and hit record in your DAW, the click or guide track audio will be sent to the LV14 for you to monitor in headphones or
control room speakers, but your final captured performance will not include these signals. Only your performance will be captured via USB into your DAW.

MICROPHONE INPUT (MIC)
This XLR combo connector will accept virtually any professional
microphone. It is designed for microphone and line level signals on either
XLR
or ¼” cables.
Some microphones, mostly condenser mics, need phantom power to
operate. Switch on 48V phantom power. If you’re unsure if your mic needs
phantom power, check the instructions or the manufacturer’s website for
information. Phantom power should not hurt most microphones, except for
very old or damaged ribbon microphones.
For live microphone use (where the microphone signal is amplified through
a PA system) engaging the HPF (high-pass filter) is recommended for
reducing “boominess” and maintaining clarity in the microphone signal.
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.
GUITAR/BASS
Passive guitar or bass signals tend to have the best sound and sensitivity
when they are connected to a high-impedance input (similar to what you
would find on a guitar or bass amp). When connecting a passive guitar
or bass signal to CH 3|4, engaging the GUITAR HI-Z switch is
recommended. It is possible to connect 2 guitar signals to CH 3|4
simultaneously. When both inputs are used, the signals will be hard-
panned left and right. If you wish to have both guitars panned to the
center so that they project from both speakers in PA setup, press the
MONO button next to the MAIN level control.
If connecting an active acoustic guitar signal to CH 1 or CH 2, engaging
the
HPF is recommended for rolling-off “boominess”.
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 meters. 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.
GAIN STAGING
Gain staging involves setting the serial amplification stages of an audio
signal in a way that achieves best signal to noise ratio. Improper gain
staging can result in more background noise, less clarity and lower sound
system efficiency. If your mixer is connected to a FOH amplifier or powered
speakers, you will need to first set the level of these for an appropriate
audience listening level. To set your FOH amplifier or powered speaker
level, connect a full-range line level music source to your mixer and set
the peak level on the channel meters somewhere between -6dB and
0dB. Set your main output level to zero/unity and slowly bring up the
amplifier or powered speaker levels to a volume that makes sense for the
venue. With this main output level set, you can move on to setting levels
for the individual inputs. Start with gain and channel level controls at their
minimum positions. For microphone signals, while speaking or singing
into the connected microphone, slowly bring up the channel GAIN control
until only the loudest input briefly triggers the channel CLIP indicator LED.
Reduce the GAIN control slightly from this level. With the main output level
control set to zero/unity, continue speaking or singing into the connected
microphone and slowly bring up the channel LEVEL to a desired listening
level. Follow this process for any microphone signals. When setting relative
levels between channels, best practice is to reduce levels of signals that are
too loud, working subtractively.
The high EQ control is a shelving EQ. What this means is that it boosts or
cuts from 10kHz 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.
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.

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.
This low EQ boosts or cuts everything from 100Hz 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.

GLOSSARY OF TERMS
BALANCED
A 3-conductor (including shield), low-impedance connection. Balanced
cables are the preferred method for hum-free interconnection of a sound
system for their noise-rejection characteristics.
(Also see Unbalanced.)
BUSS
An output destination in a mixer. For example, the left and right main
outputs are called busses, because you can send a channel to one or both
of them. Also spelled Bus
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 (DB)
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.
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.
HI-Z (HIGH IMPEDANCE)
In the audio equipment realm, the term “Hi-Z” or “High-Impedance”
generally refers to inputs designed for passive guitar or bass signals (1MΩ
or thereabouts).
HPF (HIGH-PASS FILTER)
An electronic filter that passes signals with a frequency higher than a
specific cutoff frequency and attenuates signals with frequencies lower than
the cutoff frequency.
IMPEDANCE
Resistance in an electrical circuit measured in Ohms (Ω). Maintaining
proper impedance (between amplifier and speakers for example) is
important to prevent damage to the amp.
48V 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.
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 or jacks.
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.)
