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 7|8 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 3|4 GUITAR HI-Z switch is set to the on position. While strumming the guitar, bring up the CH 3|4 channel level control to the 12 o’clock position and slowly bring up the MAIN level control until a comfortable listening level is achieved.
COMPUTER (USB CONNECTION) – With the computer’s sound output set to WAVE OUT USB DEVICE and with audio playing on the computer, bring up the CH 5|6 level control to the 12 o’clock position and slowly bring up the main level control until a comfortable listening level is achieved.
BLUETOOTH AUDIO – Follow the Bluetooth pairing instructions below. While paired and with audio content streaming from the mobile device, and with the mobile device output volume set to maximum, slowly bring up channel the 7|8 channel level control to the 12 o’clock position. Then 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.
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. When this is accomplished, slowly bring up the headphone level control until a comfortable listening level is achieved.

BLUETOOTH® AUDIO INPUT

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 LX8 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.

USB WALKTHROUGH

PLAYBACK & RECORDING VIA USB
The LX8 and LX12 are fully ASIO (Windows) and Core Audio (MAC) compliant audio interfaces and as such do not require any special driver installation.

Playback:

Make sure the LX Mixer is set as the audio output device within the PC’s system settings and within the DAW software or audio player
Start audio playback from the DAW or audio player
Press the USB ROUTING TO CH 9 |10 BUTTON (LX12 only)
For LX12: Make sure the HEADPHONE|CTRL RM SOURCE button is in the up position.
For LX8: Make sure the MIX MINUS CH 5|6 BUTTON is in the up position
Slowly bring up the CH9|10 level control for LX12 or the CH 5|6 level control for LX8

Recording:

Connect all input signals to the LX Mixer
Set the channel level controls and MAIN level fader so that the MAIN level meters show the mix peaking somewhere around 0 dB
Make sure the LX Mixer 14 WAVE OUT USB DEVICE is selected as the audio input device within the PC’s system settings and within the DAW software
Arm the stereo DAW track and press record. The LX 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 LX8’s CH 5|6 or the LX12’s CH 9|10 (when the USB ROUTING TO CH9|10 button is engaged on the LX12).

Overdubbing:

Make sure the LX 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
Reduce the LX8’s CH 5|6 and the LX12’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)
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.
On LX12, set the HEADPHONE|CTRL RM SOURCE button to the 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. On LX8, set the MIX MINUS CH 5|6 button to the in position. You will hear both the playback tracks and the signals you are recording, in the headphones signal, but the playback tracks on CH 5|6 will be excluded from the main mix bus, and kept from being re-recorded.
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. 28 12 21
See page 14 for Real-World Example.

A REAL-WORLD EXAMPLE USING THE LX12

Tracking a Vocal and a Guitar simultaneously to a click track being generated by your DAW.

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.
Plug your vocal mic into XLR or TRS input of CH1 (activating the 48V Phantom Power switch if it is a condenser mic)
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.
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.
Then turn the CH1 PAN control all the way to the right
Plug your guitar into CH 5|6 L/mono input and engage the Hi-Z button.
While watching the CH 5|6 clip indicator LED, strum the guitar. When only the loudest input briefly triggers the clip LED, reduce the CH 5|6 GAIN control slightly.
While watching the input level meters of the DAW’s guitar channel input, strum the guitar and bring up the mixer’s CH 5|6 LEVEL control until the loudest input falls just below clipping.
Now turn the Pan control on CH 5|6 all the way to the left
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.
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
Set up your DAW’s audio output to the LX12 USB and on the mixer press the USB Routing to CH 9|10 button
Set the HEADPHONE|CTRL RM SOURCE button to the MON position
Make sure the CH 9|10 level control is turned all the way down to the left (counter-clockwise) and slowly turn up the MON level control on CH 9|10.
Use the channel MON SEND CONTROLS to create a mix of 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
Now when you arm a channel and hit record in your DAW, the click or guide track audio will be sent to the LX12 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.

APPENDIX

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 on the LX8 or the CH 5|6 on the LX12, engaging the GUITAR HI-Z switch is recommended. It is possible to connect 2 guitar signals to CH 3|4 (LX8) or CH 5|6 (LX12) 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 one of the XLR equipped channels, 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.

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.

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.

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.
COMPRESSOR
A device that reduces the dynamic range of the audio signal passing through it. When compressing a signal, the louder parts of the signal become quieter, and when make-up gain is applied, the quieter, subtler parts of the signal become more pronounced. This often produces a more articulate and polished sounding signal that can stand out better in a mix.
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 threeconductor (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, twoconductor (including shield) phone plug.
TS connectors are sometimes 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.)
