• Plug the included power supply into an AC power outlet and into to the 

power input on the rear panel of the mixer

INPUT CONNECTIONS

Choose any combination of the following sources:

• MICROPHONE -

 Connect a microphone to the XLR combo input jack via 

XLR or 1/4” cable

• PHONE/TABLET/LAPTOP -

 Connect a tablet, phone or laptop to the  

CH 6|7 STEREO input jack on the mixer via stereo

BLUETOOTH

®

 AND AUDIO INPUT

OUTPUT CONNECTIONS
• HEADPHONES

 - Connect a pair of headphones to the mixer’s 1/4” 

headphone jack

• POWERED SPEAKERS

 - Connect the MAIN OUTS on the LV7 to a pair of 

powered speakers via XLR cable

POWERING UP

• Power on any devices connected to input jacks
• Power on the LV7
• Power on the powered speakers connected to the LV7’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 achieved.

  

 CAUTION:

 Leave the 48V phantom power switch turned off if phantom power is not required. In order to prevent noise and possibly damaging  

 

 

connected devices please follow these instructions:

  

 Leave 48V phantom power off when connecting a device that does not require it

  

 Do not plug or unplug any connections to CH1 of the LV7 when 48V phantom power is on

  

 Before turning on or off 48V phantom power make sure the CH1 level control is turned all the way down (to the left-most position)

• PHONE/TABLET/LAPTOP -

 Press play on the connected audio player and increase the player’s internal volume control to maximum level. Slowly bring  

up the  BLUETOOTH / CH 6|7 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 -

 Make sure the channel 2|3 GUITAR HI-Z switch is set 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 set so that ample 

signal is feeding the main and headphone buses. The meters should show b3 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 LV7 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.
