Darkglass Electronics Microtubes X Ultra Bass Preamp
The Microtubes X Ultra greatly expands on the already immense versatility of the Microtubes X7. Featuring all the great controls that its predecessor has that allows users to select exactly what frequencies they want to compress and saturate for the low and treble respectively, but with four major additions providing an additional layer of flexibility, while maintaining the same compact footprint, making it an extremely complete tool for the modern bassist.
Controls compression amount for the low band. Both threshold and makeup gain are controlled to maintain a constant level. This control is also used to control the compression amount when the compressor is enabled for clean signal in Darkglass Suite.
Sets the output volume of the low-pass signal.
Low Pass Frequency
Controls the cut-off frequency to be mixed back to the high-pass side. Ranging from 50Hz (for only sub-bass) and 500Hz to preserve some clean mids.
Sets the output volume of the distorted high-pass signal.
Sets the amount of distortion for the high pass side.
High Pass Frequency
Controls the cutoff frequency to be distorted, ranging from 100Hz (for thicker, fuzzier saturation) or 1kHz for ultra-sharp definition.
+-12 dB. Sets the overall volume of the unit.
+-12 dB @ 80 Hz.
250 Hz / 500 Hz / 1,5 kHz / 3 kHz
+-12 dB @ 5 kHz.
Balanced XLR output for connecting the pedal to a microphone preamp, PA system, etc.
Disconnects the signal ground on the Direct Output to break any ground loops. Set this switch to either position that has less noise. The switch does not affect the ¼” output.
Toggle the cabinet simulation on/off on the Direct Output. This switch completely bypasses all digital circuits and allows you to get a zero latency signal when needed.
Microtubes X Ultra has a digitally controlled headphone amplifier with a 3.5mm stereo jack output. Digital volume control is available in Darkglass Suite. Headphone volume can be controlled directly on the pedal with the master volume control when the preamp is enabled. When the pedal is on bypass, the master volume does not affect the headphone volume.
A Micro USB B connector allows you to connect the pedal to PC/Mac to load cabinet simulation impulse responses to the pedal and control various other settings. Download the free Darkglass Suite software from www.darkglass.com/suite to configure the pedal, load new impulses and download firmware updates.
Perfect for quiet practice, you can now connect your PC or mobile device to your pedal to play along with your favorite songs, and backing tracks while using the headphone output.
10.7x12 cm (4.21x4.72 in)
WARNING: When the pedal is on bypass the master volume does not affect the headphone volume. In this case, the total volume is adjustable in Darkglass Suite. With sensitive headphones, the bypass volume can be very loud if not adjusted.
The Microtubes X Ultra has a current draw of 200mA. Only use a regulated 9V DC adapter with a center-negative plug. Due to ecological reasons, it does not accept batteries. Unregulated power supplies and/or higher voltages may result in suboptimal noise performance and even damage your unit, voiding the warranty
