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, you’ve 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 we’ve equipped the BX1200 with our unique
DYNAMIZER preamp circuit that gives you a lively and punchy
sound with signal peaks—even 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.
