A custom-designed Darkglass high-efficiency class D power amplifier module is the heart of this 500 watt amplifier. It enables the usage of speaker cabs with impedance as low as 20, adding a new level of flexibility for your cabinet options. A cabinet simulation utilizes an improved version of the Darkglass Cab Sim module. The module has three slots for hi-res impulse responses which are active for both the headphone output and the balanced XLR DI output. Darkglass also added a one-knob compressor with intelligent makeup gain for level consistency and an ultra-quiet 6-band graphic equalizer.

  • Input 1/4" input: Use this to connect your instrument via a standard 1/4" mono cable.
  • Passive/Active switch: Use this push button to change from passive to active mode. If your bass is active it can have a hotter signal, making the amp distort early (feel free to use if such additional distortion is desired).
  • Microtubes switch: Use this push button to turn on or off the Microtubes Engine to add natural compression, organic harmonic enhancement and saturation ranging from mild overdrive to high gain bass rage.
  • Comp knob: This controls the amount of dynamic compression added to the Microtubes Engine. The make up gain is adjusted automatically. The compression can be turned off or assigned using Darkglass Suite.
  • Drive knob: This controls the amount of distortion that the Microtubes Engine will deliver. It will change from a soft warm overdrive to a massive modern distortion sound.
  • Tone knob: This controls the high harmonic content of the Microtubes Engine via a variable low pass filter: crank it up for additional attack and definition or dim it down for a smoother sound, especially handy if already running bright clean EQ setting or cabinets with tweeters.
  • Level knob: Use this to control Microtubes Engine's output volume.
  • Blend knob: Use this to mix between the clean signal and the distortion signal (Microtubes Engine).
  • B3K/VMT switch: This push button selects between two overdrive voicings: B3K mode will deliver an aggressive, percussive sound while VMT will bring up the mids for a warmer, more neutral character.
  • Bass EQ slider: +-12dB at 80Hz. Use this to change the low content of the signal.
  • Mids EQ sliders: +-12dB at 250, 500,1.5K and 3Khz. This graphic eq control the mid content of the signal.
  • Treble EQ slider: +-12dB at 5kHz. Use this to change the high content of the signal.
  • Master knob: Use this to control the overall volume of the amplifier.
  • Mute switch: Use this push button to mute the amplifier.

  • Speaker Output Speakon / 1/4" combo output: Use this connector to connect the amplifier to your cabinet. This Speakon combo jack allows for either Speakon or 1/4" speaker cable operation.
  • Send 1/4" output: Use this to send the signal to effects pedals.
  • Return 1/4" input: Use this to receive the signal from effects pedals. Master volume control is after this input.
  • Gnd Lift switch: Use this to lift the ground of the DI XLR output. If you are experiencing ground noise in your DI signal, try changing the setting of this control.
  • DI Output XLR output: Use this 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.
  • USB port: The allows you to use Darkglass Suite to load different cabinet impulses or change different parameters on your amp.
  • Headphones 1/4" output: Connect your headphones and enjoy the impulse based cabinet emulation.
  • Aux In 1/8" stereo input: Use this to provide to the headphone output music from your laptop, cellphone, mp3 player, etc.
  • Cab Select switch: Use this to navigate among the 3 different cabinet impulses or the clean DI signal.
  • Footswitch 1/4" input: Darkglass Intelligent Footswitch (sold separately) is a proprietary, digitally-controlled device that allows you to remotely engage and disengage the Microtubes Engine. You can also hold the footswitch to mute the amplifier. The VMT/B3K push button will remain operational with Intelligent Footswitch plugged in.
  • AC IEC connector: Use this to feed electric power to the amplifier. 100 - 230 VAC, 50Hz-60.
  • Power on/off switch: Use this to release the audio energy from your bass.
