Darkglass Electronics Alpha-Omega 900 900-Watt Bass Head - Authorized Dealer
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 amplifier with earth-shattering tone. While Darkglass' signature Alpha and Omega drive engines add 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 from aggressive and overdriven to crystal clear clean, whatever your needs may be.
That's not everything though, 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.
The Alpha Omega 900 amplifies the best qualities of one of the most powerful and distinct Darkglass products ever made.
Front Panel Features Input
Use this jack to connect your instrument via a standard ¼" mono cable.
Active/Passive
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 Alpha·Omega Engine™ to add natural compression, organic harmonic enhancement, and saturation ranging from mild overdrive to high gain bass rage.
The Alpha·Omega Engine operates before the clean section (you can therefore use the 6-Band Active EQ for additional tone shaping).
Bite
Boosts high mids (2.8kHz) for additional presence and definition.
Growl
Shelving Bass Boost for a fatter tone and increased low end saturation.
Compression
This knob controls the amount of dynamic compression added to the Alpha·Omega Engine. The make up gain is adjusted automatically. The compression can be turned off or assigned using the Darkglass Suite.
Drive
This knob controls the amount of distortion that the Alpha·Omega Engine will deliver. It will change from a soft, warm overdrive to a massive and modern distortion sound.
Level
Use this knob to control Alpha·Omega Engine's output volume.
Blend
Use this knob to mix between the Clean signal and the Distortion signal (Alpha·Omega Engine).
Mod
Selects or mixes between the two distinct distortion circuits: Alpha is punchy, tight with a lot of definition, whereas Omega is simply brutal and raw.
Gain
Use this knob to change the volume of the signal before the Active 6 Band EQ. You can set it low for ensuring the cleanest operation possible or set it higher for a more aggressive growl.
Bass
+-12dB at 80Hz. Use this knob to change the low-end content of the signal.
Mids
