Darkglass Microtubes X Ultra User manual

Microtubes X Ultra

Multiband Distortion

The Microtubes X Ultra allows you to select exactly what
frequencies you 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.

Warning

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

Warranty

To activate the warranty, we encourage you to register your
product on: http://mypedal.darkglass.com and enter the serial
number on the back of your pedal.

Controls

High Pass Frequency: Controls the cutoff frequency to be

distorted, ranging from 100Hz (for thicker, fuzzier saturation)
or 1kHz for ultra-sharp definition.

High Drive: Sets the amount of distortion for the high pass side.
High Level: Sets the output volume of the distorted high-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.

Low Comp: 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.

Low Level: Sets the output volume of the low-pass signal.
Clean signal compression: To enable the compressor for

clean signal, please install Darkglass Suite
(www.darkglass.com/suite) and connect the pedal via USB.
After enabling the mode in Suite, you can hold the Bypass
footswitch for 2 seconds. When the lights on the pedal are
blue, the compressor is enabled for clean signal. In both blue
and red modes the distortion is identical.

Sliders
Master: +-12 dB. Sets the overall volume of the unit.
Low shelf: +-12 dB @ 80 Hz.
250 Hz / 500 Hz / 1,5 kHz / 3 kHz: +-12dB.
High shelf: +-12 dB @ 5 kHz.

Direct Output: Balanced XLR output for connecting the pedal

to a microphone preamp, PA system, etc.
Ground lift: 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.

Cab Sim: 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.

Headphones: 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. On bypass the volume has to be

adjusted in Darkglass Suite.
With sensitive headphones, the bypass volume can be very

loud if not adjusted!
USB: 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.
