Darkglass Alpha Omega 900 Owner`s Manual

OWNER’S MANUAL

The Alpha·Omega 900 takes the best elements of our most successful distortion

preamplifier ever, combined with state-of-the-art features to make a monstrous 900-watt

While our signature Alpha·Omega® drive engines and incredible girth and size to the

overdriven signal, the studio-grade VCA compressor adds an extra layer of control, and the

ultra-quiet 6-band graphic equalizer can help sculpt the tone in any way necessary, as

well as providing a wide variety crystal clear clean sounds.

But that is not everything: the MIDI programmability and impulse response cabinet

simulation with up to three different storable virtual cabinets make the AO900 not only

one of the most complete amplifiers for the touring musician but, combined with the

auxiliary input and headphone output, the ideal tool for silent practicing. OR but also the

ideal tool for silent practicing, when combined with the

amplifier with earth-shattering tone.

auxiliary input and headphone output.

The Alpha·Omega 900 amplifies the best qualities of one of the most powerful and

distinct Darkglass® pedals ever made.

DESCRIPTION

The Alpha·Omega 900 is a 900W amplifier equipped
with an all-analog preamplifier, Class D Power Module
and a digital impulse based cabinet emulator for DI
outputs or headphones. Probably the first thing you
will notice from the Alpha·Omega 900 is its unusual
control layout: On the right side you’ll find the clean
section which is the foundation of your sound.

It features Gain and Master volumes and active 6 band
graphic EQ. Along with the mandatory Low and Treble
controls you will find 250Hz, 500Hz, 1.5KHz, 3KHz
sliders. Character is all in the midrange. Having 4
dedicated Mid controls allows you to cover the whole
mid range (250Hz to 3kHz) to have total control and
flexibility over the amplifier’s character.

On the left side, by the input jack you will find the
Alpha·Omega Engine which acts as an extra channel.
This creation differs greatly from our previous
preamplifiers and overdrives: its operational-amplifier
topology featuring two distinct distortion circuits
(Alpha and Omega), which can be selected or blended
using our Mod knob, make the Alpha · Omega® the
most flexible among our designs.

The Alpha·Omega Engine can be engaged via the front
panel or via our own digitally controlled (jack on rear
panel). Besides engaging the Alpha·Omega circuitry
you can hold the actuator to Mute the amplifier.

The Intelligent Footswitch is housed in an elegant,
laser-engraved unibody chassis and requires a
standard ¼” mono cable (not included) for it’s full
operation.

Besides this incredibly versatile preamplifier, we
equipped the power module with some unique control
over the power output and minimum speaker loads:

The standard mode will deliver 900W RMS at 4Ω/500W
at 8Ω. If you select the 2Ω Mode via the rear-panel
switch the amplifier will deliver 900W at 2Ω/500W at 4Ω
and 350W at 8Ω.

This deceivingly simple feature allows for maximum
power adaptability: Regardless of the cabinet
configuration or power requirements, the Alpha· Omega
900 will deliver accordingly.

FEATURES

FRONT PANEL

INPUT : Use this jack to connect your instrument via a
standard ¼” mono cable.

PASSIVE/ACTIVE : Use this push-button switch to
change from passive to active mode. If your bass is

active it can have a hotter signal making the amp to
distort early (feel free to use if such additional
distortion is desired).

DISTORTION: Use this push button to turn on or off the
