Manual Alpha·Omega 500

500W Bass Amplifier

Specs

Controls

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 that makes the amp distort early (but feel free to use if such additional distortion is desired!).
Distortion: Use this push button to turn the Alpha·Omega Engine on or off 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 makeup gain is adjusted automatically. 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, modern distortion sound.
Level: Use this knob to control the output volume of the Alpha·Omega Engine.
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 and tight with a lot of definition, whereas Omega is simply brutal and raw.
Bass: +-12dB at 80Hz. Use this slider to change the low-end content of the signal.
Mids: +-12dB at 250, 500, 1.5k and 3kHz. These sliders control the mid content of the signal.
Treble: +-12dB at 5kHz. Use this slider to change the high content of the signal.
Master: Use this knob to control the overall volume of the amplifier.
Mute: Use this push button to mute the amplifier.

Warning

  • There are no user-serviceable parts inside the amplifier. Do not open the amp.
  • Never use the amp in a high moisture environment or near liquids.
  • The Alpha·Omega 500 can deliver more than 115 dB of power. Exposure to this level of sound can damage your hearing. Always use proper hearing protection when exposed.
  • The Alpha·Omega 500 can deliver more than 500 Watts. Be sure that your speaker cabinet is able to deliver that power.
  • Do not cover the vent holes. The fan and vent holes are part of the cooling system of the amp. Covering the vent holes can lead to overheating and damage to the amplifier.
  • Do not use an instrument cable as speaker cable. An instrument cable is not designed to deliver the type of power sent from the amplifier to the speaker.

 

Troubleshooting

  • The button controls do not react: check if the footswitch is connected. If you do not want to use the footswitch, you have to unplug the cable from the rear panel of the amp.
  • The amp does not turn on: check if the power cable is connected and if you have power from the wall.
  • The sound is low: check your speaker cable. Never use an instrument cable.
  • The sound is distorted or too high: check if the passive/active switch matches your bass.
