AMUMU GLORIFIER™ Acoustic Preamp DI Direct Box

Regular price $169.99

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 and ukuleles 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.
