    Taurus QUBE-350 Acoustic has been designed mainly for double bass players, however, it can also be successfully used to amplify bass guitars.

    The amplifier is equipped with two channels which can serve double bass in several ways. A microphone or piezo pickup can be use to amplify the instrument. Each source can be connected to independent channel and at the same time both of them can be mixed.

    Two different instruments can also be connected to the amp's channels at the same time and used simultaneously.

    Each of the channels is designed with a separate tone correction and GAIN control, which gives great flexibility in setting of expected tone of the instrument.

    The tone correction is very transparent/neutral, without any "underlines" so that exact sound of the instrument can be reproduced.

    The amplifier is built in analog technology using a class D power amplifier. Such a combination make it possible to obtain small dimensions and weight.

    • Power output: 350W RMS / 4ohms, 200W RMS / 8 ohms
    • XLR inputs: 100 kohms (balanced) suitable for microphone or instrument with balanced output.
    • JACK inputs: 1Mohm (unbalanced) - universal, suitable for instruments with active and passive pick-ups.
    • PHANTOM - 48V condenser microphones power supply
    • 2 channels: A and B with separate tone and dynamics adjustment.

    Channel A adjustment:
    • GAIN - preamplifier input section gain control
    • DBS - bass and treble color enhancement (contour character)
    • BASS and TREBLE equalizer with the "MLO" system
    • MIDDLE - mid tones control

    Channel B adjustment:
    • GAIN - preamp input section gain control
    • BASS and TREBLE equalizer with "MLO" system
    • MIDDLE - PARAMETRIC EQUALIZER for precise mid-range adjustment

    • VOLUME control for A and B chanels
    • Channel switch: (A), (A + B), (B)
    • MUTE - quick amplifier mute
    • PHASE - signal phase inverter in the "B" channel

    Additional functions and features:
    • Subsonic filter - cuts the signal band below 40Hz on the preamp's inputs
    • Effect loops: SEND / RETURN serial loop
    • LINE-OUT - line output with cabinet simulation.
    • GROUND LIFT - circuit switch on the linear output
    • Power amplifier overload LED indicator
    • Power amplifier clipping LED indicator
    • Power selector 230V / 50Hz - 115V / 60Hz
    • PROTECTION: thermal, short-circuit and overload protection
    • Overall dimensions: 83 x 225 x 180 mm
    • Weight: 2.0 kg

    The shape of the knobs is well thought out though! Those knobs are the perfect shape to jam together and still be able to freely turn each one
  4. No Adjustable HPF?

    Looks cool, but could definitely go for a variable HPF and a notch filter. I do like the sweepable mids

  8. Yeah, really needs an HPF if they're going for the upright market.

    I’m playing an ancient Walter Woods MI100-8, and this Taurus is the first one to intrigue me for double bass in a long time. Could be a way to get rid of excess boxes (mic preamp/phantom), and reminds me a bit of the EA Doubler. I might give it a whirl.

    Acoustic Image and Mesa are the current front runners for me. Both can safely drive a 2-Ohm load, both are equipped with variable high-pass filters, both sound good. I have no use for the wood end caps because they add weight and width with no sonic benefit.

    I love the 1/4" / XLR combo input jacks. The size of about 3.25" x 8.9" x 7.1" is good. The mute switch is visible, but not illuminated.

    I would love to see a pedal board powered by an amp with phantom power, but I've never seen anything like it.

    Going to be tough to compete with AI when you have only 350 watts and no HPF.

    kind of pretty looking though

    I'm curious about the Taurus cab.

    well, EBS kinda did this for their pedals and (pre)amps. when plugged via TRS, the amp provides 9v power to pedals.

    while their 90s gear had that ability, their current offerings don't, I believe. maybe it appeared not that useful like they expected when launching it.

    I've got an EBS Octave pedal with that exact setup. Always been intrigued by the idea... but never powered it that way. Great pedal though!
