THD-450

The Taurus THD-450 is a 450W double preamp bass head amplifier based on transistor and tube simulation preamps. The transistor preamp ensures great dynamics while the tube simulation one provides a warm, soft tube sound. Both preamps can be steplessly blended to offer the whole spectrum of desired sounds, ranging from crisp and clear to slightly overdriven tube. The Taurus THD-450 is equipped with a very effective and easy to operate the MLO tone control system designed to find the right sound quickly. The special design of the tone control enables revealing the character of the particular instrument meeting its both technical and musical parameters. Extra precise control over middle range is effected by a parametric equalizer and preamp filters switches. Even thought the amplifier is operating in very low frequencies, the bass sound is still impressively selective. Unique high quality OPTICAL LIMITER is built in for fast and noiseless operation.

The amp is powered by outstandingly efficient high energy Switching Mode Power Supply which ensures extremely high dynamics and power in a lightweight and compact cabinet.

Power output: 450W RMS / 4ohm , 300W RMS / 8ohm
Main features: 2 preamps - tube simulation and transistors / analog device / SMPS
Inputs: passive & active

Controls:
GAIN control with overload indicator. Operating with Gain and Input Mix player can obtain sound very close to acoustic bass or fretless bass guitar. The area around knobs marked by a break-off line indicates the region where the level of compression and distortion allows achieving the desired effect.
MIX fluent signal adjustment of the input between 2 sections of the amplifier - tubes simulation and transistors.
COMPRESSOR/LIMITER to control dynamic of sound
VOLUME control

BASS and TREBLE equalizer with "MLO system" (Middle-range Level Optimization).
Triple BASS-switch to reduce or boost low frequency [DBS-cut/OFF/DBS-boost]
Triple TREBLE-switch to reduce or boost high frequency [CUT/OFF/PRESENCE]
PARAMETRIC EQUALIZER for precise control of middle range (120Hz-4kHz)
PUNCH button - increases sonic expression
