Darkglass Alpha Omega AO900 900 Watt Bass Amplifier Head w/Alpha Omega
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.
- Input: Use this jack to connect your instrument via a standard ¼” mono cable.
- Blend: Use this knob to mix between the Clean signal and the Distortion signal (Alpha·Omega Engine).
- Treble: +-12dB at 5kHz. Use this knob to change the high content of the signal.
- Drive: This knob controls the amount of distortion that the Alpha·Omega Engine will deliver. It will cover a wide range of overdriven tones from subtle break up to overly distorted sounds.
- Bass: +-12dB at 80Hz. Use this knob to change the low-end content of the signal.
- Master/Mute: Use this knob to control the overall volume of the amplifier. Use this push knob button to mute the amplifier.
- 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.
- Mids: +-12dB at 250, 500, 1.5k and 3kHz. These sliders control the mid content of the signal.
- 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 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.
- Dimensions: Width: 26.7 cm / 10.25″, Length: 25.5 cm / 10”, Height: 7.1 cm / 2.75″, Weight: 2.4 kg / 5.3 lb

- DI Output: Use this connector to send your signal to the console, mic preamp, interface, etc. Both signals are available (Bypass and the amp signal with cabinet simulation) and are switched from the cab select switch.
- AC Socket: Use this connector to feed electric power to the amplifier. 100 – 230 VAC, 50-60Hz. Set the voltage selector switch to the correct position before turning on the amplifier!
- AC Power Off: Use this Switch to release the audio energy from your bass.
- Headphone Output: Connect your Headphones and enjoy the analog cabinet emulation.
- Aux In:Use this connector to play music from your laptop, phone, MP3 player, etc. This input is routed only to the headphone output without cabinet emulation.
- Send: Use this output to send the signal to effects pedals.

- USB: The USB connector allows you to use the Darkglass Suite to load different cabinet impulses or change different parameters on your amp.
- Cabinet Select: Use this switch to navigate between the 3 different cabinet impulses or the clean DI signal. This selection will define both the XLR and headphone out signal.
- Footswitch: The Intelligent Footswitch is a proprietary digitally controlled device that allows you to remotely engage and disengage the Alpha·Omega Engine. You can also hold the footswitch to Mute the amplifier. You can also hold the footswitch to Mute the amplifier. The distortion push button will remain operational with the Intelligent Footswitch plugged in..· You can use a regular mono instrument cable to connect the amplifier to the footswitch.· You must remove the cable from the footswitch jack in the rear panel if you want to control the amp from the front panel.
