1.1 The design concept

We designed the BX1200 to finally start the world of bass amp

design moving. Your absolutely low-noise and indestructible Bass

Workstation represents the current state of the art.

The robust cabinet is made of high-grade and non-polluting E1-

MDF boards, which are grooved, multi-glued and free of

formaldehydes. This is to make sure that your BX1200 keeps on

working even when the going gets tough.

1.1.1 The DYNAMIZER technology

When it comes to amplifying the signals delivered by electric

instruments, youve got to separate the wheat from the chaff.

Unlike mixed or mastered signals, electric instruments usually

deliver extremely high signal peaks which, when raised in gain,

produce nasty distortion. How an amplifier responds to these

signal peaks can therefore be seen as one of its most essential

quality features.

Many manufacturers use limiters preceding the power stage to

limit dynamic signal peaks. However, the problem is the preamp,

which is why weve equipped the BX1200 with our unique

DYNAMIZER preamp circuit that gives you a lively and punchy

sound with signal peakseven if the amp reaches its power

limits. Extreme signal peaks are limited effectively while the

average level and hence the power of the overall signal is raised.

The sound gets more vivid and powerful in character, without

any unmusical distortion. With its opto-limiter in the power stage

it is virtually impossible to overdrive the ULTRABASS BX1200.
