INTRODUCTION
The Cali76 Compact Series is a range of premium-quality, 1960s-style FET compressors, each inspired by the legendary Urei 1176.
The idea behind the range was to bring the sonic properties of this revered studio classic into the scope of the average guitar geek…
The topology of each design was kept true to the ori gi n al , while the actual circuitry has been carefully condensed. In th i s way it has
been pos s i bl e to retain the much-loved dynamic response of the original, while at the same time permitting a smaller, more stage
friendly format.
Excluding the VU meter (where appl i ca bl e), the circuitry is wholly trans i s tor -bas ed (otherwise known as "discrete"). Well designed
transistor circuits, in contrast to IC-based designs, gener ate fewer harsh distortion artefacts. In addition, subtle harmonics are
created which can positively enhance tone.
We've included a studio-grade 1960s-style discrete preamp, to work as an electronic interface between your guitar and the
compressor. T h e preamp provides gain and also creates the optimu m conditions for signal transfer.
In designing the Compact Series pedals, Origin Effects has gone to painstaking lengths to preserve the build quality and sonic
integrity of the original Cali76 and SlideRIG circuits, even improving on them where possible.
The further reduction in siz e has been achieved by using a mixture of traditional through-hole and SMD components, spread across
a pair of densely populated, stacked boards. The sig na l path utilises film and tantalum capaci tor s , carefully chosen low-noise
transistors and rugged MELF resistors (essentially traditional through-hole resistors wi th out the leads), which offer low-noi s e
performance and rock-solid reliability.
One of the reasons why the original Origin pedals sound so good is that they deliver true FET compression, with a fas t yet h i gh l y
musical response that is a world away from the brutal and unforgiving sound of tradi ti on al VCA compressor pedal design s . T h e n ew
Compact Series pedals stay true to Origin's design philosophy with absolutely no opamps or VCAs used in the signal path.
The new pedals are powered by mains adaptor only. Dispensing with the usual intern al 9V battery option allows more space inside
the enclosure for high-quality circuitry, while also supporting the high-cu r ren t circuit design that is the key to these pedals'
astonishingly low noise levels.
