AMUMU GLORIFIER™ acoustic preamp direct box is fully handcrafted with extremely low noise, excellent clarity and warm EQ. It is designed for all acoustic-electric instruments with various pickups. It’s built with +/-20 dB Gain control and 3-band EQ, powered by either 9V DC adapter(center negative), 48V phantom power or the 9-volt battery, connected with 1/4” Unbalanced Input, XLR Balanced Output and 1/4” Unbalanced Output.

FEATURES

Handmade Preamp DI Box for various acoustic-electric guitars with piezo, magnetic, under-saddle and microphone pickups.

+/-20 dB Gain control with 3-band EQ, Super-Low Noise and Sparkling Acoustic Clarity.

Phase Switch to reduce feedback and also to generate a fuller and warmer tone.

Powered by either 9V DC adapter(center negative), 48V phantom power or the 9-volt battery.

Convert high impedance unbalanced signal from the acoustic-electric instrument to low impedance balanced signal for the mixer, PA system, recording audio interface and microphone preamp. ( 1/4” Unbalanced Input to XLR Balanced DI Output plus a 1/4” Unbalanced Output )

POWER REQUIREMENTS

The AMUMU GLORIFIER™ Preamp DI can be powered by any of the following 3 methods.

Any standard 9V DC center negative power supply/adapter using a standard 2.1mm center pin and 5.5mm outside barrel (not included)

12V - 48V Phantom Power through D.I. output (XLR cable needed, Mixer/Audio Interface with built-in 48V phantom power needed)

A PP3-size 9-volt battery (Alkaline 6LR61, not included)

Unscrew the bottom cover to install the battery

The battery will not be drained or charged when using with phantom power or DC adapter

Unplug the input cable when not using to power off the unit

INPUT

INPUT (MONO PLUG): 1/4” Line In with mono plug from the acoustic-electric instruments ( guitar, bass, ukulele, cajon, banjo, etc)

OUTPUTS

OUTPUT (UNBALANCED): 1/4” Line Out with mono plug

D.I. OUTPUT (BALANCED): XLR DI output to low-impedance devices like the mixer, microphone preamp, PA system and recording consoles.

PS: The DI XLR output and the line output can be used simultaneously. Either you can use the 1/4" line out as a monitor for connecting to a tuner or as an output for connecting the guitar(instrument) amplifier while using the DI output with a mixer or PA system.

CONTROLS

GAIN: Controls the Input Sensitivity from the instruments and sets the amount of pre-amplification before the signal enters the EQ section.

VOLUME: Located at the OUTPUT (the very end of the circuit) and simply allows you to adjust the volume.

BASS: Controls the amount of bass in your signal. Left is less, right is more

MID: Controls the amount of mid frequencies in your signal. Left is less, right is more.

TREBLE: Controls the amount of treble in your signal. Left is less, right is more.

PHASE: Reduce feedback hum

LEDS

48V: This LED will light on when using with phantom power only.

ON: This LED will light on while using with any of the 3 power methods but only when the INPUT jack is plugged with a mono cable.
