Voiceprint DI User’s Guide
INTRODUCTION
The product of nearly 3 years of intensive research and collaboration with a team of PhDs, LR Baggs is thrilled to introduce Voiceprint DI, the next breakthrough chapter in acoustic amplification. Voiceprint DI measures the acoustic response of your guitar and leverages the processing power of your smartphone to accurately capture your guitar’s one-of-a-kind voice. A Voiceprint is created and loaded to your Voiceprint DI pedal, replacing your pickup’s signal for the most accurate sonic performance we have engineered in our 40+ years.
IMPORTANT
For full use of this product, it is necessary to use the Voiceprint DI with
our Acoustic Live app on your smartphone.

designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions:(1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
The device has been evaluated to meet general RF exposure requirement.
The device can be used in portable exposure condition without restriction.

TO GET STARTED
- Plug in a 9-volt DC power supply (provided).
- Plug your guitar into the INPUT of the Voiceprint DI (upper right hand side of the box) and a cable to either the 1/4″ OUTPUT (upper left hand side) or the XLR output located on the back panel of the unit.
- Plug the output cable into your amp or PA to listen back to your Voiceprint after you’ve made one. To learn more about the Voiceprint creation process, reference the Acoustic Live app. To learn more about the specifics of the Voiceprint DI, continue on with this manual.
TOP
A. Anti-FB
This control is used to adjust the mix of your Anti-Feedback profile. When
turned counterclockwise to 0, the Anti-Feedback profile will not affect the
signal. Turn clockwise to add Anti-Feedback profile. Additionally, clicking
this knob will invert the phase. *For more in depth Anti-FB control, reference
the Acoustic Live app.
B. Voice
This control is used to adjust the mix of your Voiceprint, your guitar’s one-
of-a-kind voice. When turned counterclockwise to 0, the Voiceprint will not
affect the signal. Turn clockwise to add Voiceprint profile. Additionally, a
long press of this knob will enter Bluetooth pairing mode. *For setting up a
Voiceprint and more in depth Voiceprint control, reference the Acoustic Live
app.
C. Select
This control is used to select which of your paired Voiceprint and EQ presets
to use. The Voiceprint DI can hold up to 100 presets. Turn clockwise to scroll
up and counterclockwise to scroll down. The highlighted preset will flash on
the digital display. Click the knob to activate the currently selected preset
slot. If you idle for too long or click on a slot that does not have a preset
saved in it, the Voiceprint DI will default back to the previously selected
preset slot. *For more in depth control over your preset library, visit the
Acoustic Live app.
D. Volume
This is a Master Volume that functions independently from the Acoustic Live
app. This will control the levels of both the ¼” out and the XLR out. Both of
these outputs will be muted when the Mute footswitch is engaged.
E. Pad
The pad switch is used to attenuate the input by 0dB (no change), -3dB, -6dB,
or -9dB. Adjust this depending on the output of your pickup. A visual
indicator of the pad’s level will appear on the digital display when the
switch is used.
F. Mute
This footswitch is used to mute the signal from both the ¼” out and the XLR
out. A solid light will appear above the footswitch when the Mute is engaged.
Additionally, this footswitch can be held to engage a Bypass function. Visual
indicators of the Bypass function include a flashing light above the
footswitch and BYP on the digital display.
G. Next
This footswitch is used to scroll through the stored presets on the Voiceprint
DI. Press the footswitch to activate the next stored preset.
Side
A. DC Input
The DC power input is designed for a standard 2mm plug commonly used with
effects pedals and “floorbox” products. A power supply is provided with the
Voiceprint DI. Most power supplies or multi-power devices designed for musical
products may be used. 9VDC recommended with a 12VDC maximum. Plugging in a
power supply will activate the Voiceprint DI.
B. 1/4″ Input
The ¼” input is an unbalanced (mono), all-discrete input.
C. 1/4″ Output
The ¼” output is an unbalanced, line level output. You can plug into any amp
or device that has a ¼” input. We recommend running into any other LR Baggs
Align pedals, DI’s, or the Synapse Personal PA System.
Back
A. USB
This USB port is used to connect your Voiceprint DI to a computer for
potential firmware updates.
B. EFX
Send Connect a standard 1/4″ mono cable from this jack to the input of an
effects pedal or rack device.
C. EFX Return
Connect the return of the output of an effects pedal or rack device to
interrupt the signal and complete the series effect loop.
D. XLR Output
The DI out is a balanced XLR output for connecting to a mixing board with an
XLR (mic) cable.
E. Ground Lift
Engage this switch to reduce or eliminate ground loop related noise.
