Choose any combination of the following sources: 

•  MICROPHONE -Connect a microphone to an XLR combo input jade via XLR or 1/4″ cable
• PHONE/TABLET/LAPTOP – Connect a tablet, phone or laptop to the CH 718 STEREO input jack on the mixer via stereo 3.5 mm TRS cable
• GUITAR/BASS – Connect a guitar or bass with a passive pickup to the channel 314 L/MONO input via standard 1 / 4M guitar cable

CHECK KNOBS AND SWITCHES

• Tum all white-<:apped level knobs to the minimum (lull counter-<:lockwise} position.
  These are the CH 1 – CH 516 GAIN and level controls and the MAIN level control.

• Tum all grey-capped and blue-capped knobs to the 12 o’clock position.
  These are the PAN, BAL and EQ controls

• All buttons should be in the up position. The white bottom edge of the button will be clearly visible and 48V and SOLO LEDs should be off.

OUTPUT CONNECTIONS

• HEADPHONES- Connect o pair of headphones to the mixer’s 1/4• headphone jade.
• POWERED SPEAKERS – Connect the MAIN OUTS on the LVB to a pair of powered speakers via XLR coble

POWERING UP

• Power on any devices connected to input jacks
• Power on the LVB
• Power on the powered speakers connected lo the LVB’s MAIN OUTS

SETTING LEVELS

• MICROPHONE- If you have connected a condenser microphone, press the 4BV switch (Iha 4BV LED will coma 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 boniness· or bass in the microphone signal,
  set the BOHz 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 loudasl input briefly triggers the channel 1 CLIP indicator LED. Reduce the GAIN control slightly from this level. Continua speaking or singing inlo Iha 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 achieved.

• PHONE/TAILET/LAPTOP-Pass play on the connected audio player and increase the player’s inlamal volume control lo maximum level.
  Slowly bring up the BLUETOOTH I CH 617 STEREO level control to the 12 o’clock position, then, slowly bring up the MAIN level control until a comfortable listening level is achieved.

• GUITAR-Maka sure the channel 314 GUITAR HI-Z switch is sat to the on position. While strumming the guitar, slowly bring up the MAIN level control until a comfortable listening level is achieved.

• POWERED SPEAKERS-To monitor through powered speakers, slowly bring up the MAIN 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 sal 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® AND AUDIO INPUT

The mixer powers up with Bluetooth off. Press the PAIR button to initialize Bluetooth and activate pairing (the PAIR LED will Rash, indicating that it is ready lo pair). The LVB 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 o 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

APPENDIX

MICROPHONE INPUT (MIC)

• This XLR combo connector will accept virtually any professional microphone. It is designed Far microphone and line level signals on either XLR
  or 1/4 cables.

• Some microphones, mostly condenser mikes, 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 Far information. Phantom power should not hurt most microphones, except Far very old or damaged ribbon microphones

• For live microphone use (where the microphone signal is amplified through a PA system) engaging the H PF (high-pass filter) is recommended for reducing “boominess” And maintaining clarity in the microphone signal.

Use the microphone preamp’s goin control [explained below) to bring the microphone up to a high enough level to use with the mixer.

LINE INPUT (LINE)

• This 1/A” 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 some channel.The mixer will distort ond 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 o 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 ore connected too 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 314, engaging the GUITAR HI-Z switch is recommended. It is possible to connect 2 guitar signals to CH 314 simultaneously. When both inputs are used, the signals will be hard­panned left and right. If you wish to have both guitars panned to the
  center so thot they project from both speakers in PA setup, press the MONO button next to the MAIN level control.

• If connecting on active acoustic guitar signal to CH l 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 tum it up at the level control. If goin is set too high, it will distort.
• For best performance, set the gain while looking at the meters. Tum the Level control so that it’s lacing straight up. Then tum 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 odd together and distort the mixer.

Sidebar: “Why are there two volume controls?”

• The Gain and Level controls works 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 the best signal-to-noise ratio. Improper gain staging can result in more background noise, less clarity and lower sound system efficiency. II your mixer is connected to a FOH amplifier or powered speakers, you will need to first set the level of these Far 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 peal. level on the channel meters somewhere between -6dB and OdB. Set your main output level to zero/unity and slowly bring up the amplifier or powered specie.er levels to a volume that makes sense for the venue
• With this main output level set, you con move on to setting levels for the individual inputs. Sta rt 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 the 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 ore too loud, working subtractively.

The high EQ control is a shelving EQ. What this means is that it boosts or cuts from l Ole.Hz 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 squeals on a guitar or boss.

The high EQ control is a shelving EQ. What this means is that it boosts or cuts from 121c.Hz and everything above that. Turn it up to bring out the breath of a vocal or the high overtones of the cymbals.
Turn ii down to reduce finger squeaks on a guitar or boss.

1. 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 tum it down if a percussion part is too harsh.
2. This low EQ boosts or cuts everything from 1 OOHz or below. You might bring it up for more bantam out of your kick or boss guitar, and tum it down to reduce rumble from a vocal or wind instrument.
