OPERATING MANUAL

Dear bass player! You have one of the smallest and the most
effective amplifiers as well from the sign of Taurus. We hope that
this gear will come up to your expectations.
Taurus Qube − 450 bass head is the smallest and the lightest bass
amplifier in Taurus's amps line. The compact size of the head was
attained by applying the newest, most advanced technology.The
SMPS (Switch Mode Power Supply) power supply and Class D
power amplifier in conjuction with classic analog pre−amp provide
great efficency, power, dynamic and sound selectivity . As all
Taurus amps, the Qube − 450 is very easy to operate.The MLO
system equalization control in which the Qube is equipped with,
achieves easy and intuitive tailored sound using only bass and
treble potentiometers.This sound correction simplifies finding the
right tone colour of an instrument.

The “MLO” (Mid Level Optimization) is Taurus proprietary system allowing
for an easy, intuitive and extremely comfortable optimization of the overall
sound of the bass guitar.
The MLO System provides all new possibilities. It ensures most accurate
proportion of medium frequencies in accordance of your manual settings
of bass and trebles. This very intuitive and logical system supports
musician's choice for most desirable sound.
In addition, the MLO equalizer ensures virtually no change in overall volume
while changing the bass frequencies. Unlike most of the standard amps,
adjusting bass frequency the musician notices change of the sound not the
volume.

Connect a cabinet of the proper power and impedance to the amplifier, see
page 5 in the operation manual.
It's recommended to connect 4 ohm cabinets with Speakon−Speakon
cable. This link warrants better connection quality and reliability then
Jack−Jack cable.
Connect your bass guitar to one of the inputs Active or Passive depending
on your instrument, then turn the power on.
Turn on the Volume in optimal position, then you can start playing if your
gain level is too small, set the gain knob to desired level. Don't let the
preamp to be distorted by setting to big gain level.
Next step will be creating your sound colour using controllers and
switches available on the front panel.
Set every front panel controllers and switches on following positions:
− GAIN, BASS, MIDDLE, TREBLE controllers in middle position,
− Tone switches in middle position.
PRECAUTIONS
GETTING STARTED
MLO − SYSTEM Middle−range Level Optimization CAUTION! It is necessary to comply with basic rules while using devices
supplied from AC power.
The device should be supplied with current of parameters complied with
markings on the product.
It is recommended to use plugs with grounding. Without grounding while
touching and adjusting metal knobs of the amplifier, small crackling can be
audible.
The amplifier should be place in a spot that anables free air circulation for
the cooling system to work properly.
Use fuses of parameters recommended by the producer only.
It is necessary to remember that too loud play may cause hearing
damages.
Protect the device against moisture.
A perfusion of the device may cause damage or electric shock.
The device should be used away from a heat sources.
Never try to repair the device personally.

PROTECTIONS
4
This amp is armed with several Power Amp protection circuits. PROT LED
placed at front panel of the unit indicates their activity. If PROT illuminates
with constant light while instrument is connected, that means Power Amp
is blocked by PROTECT circuits. Temporary overload or short circuit at
Speaker Output will cause PA to be blocked for about 4 seconds. After this
time amp will start working again without any user action. If this kind of
situation occurs, cabinet connection and impedance should be checked
(lowest possible impedance is 4 ohms). If amp does not restart after 4
seconds, that may indicate Power Amp has overheated. It may take few
minutes before the cooling system will decrease temperature of PA to the
safe level.
