About the Juggernaut

THE JUGGERNAUT is an all Class A discrete, tranformer coupled 500 series preamp by APA, designed by Tim Farrant and Nathan Eldred.

The Juggernaut features custom wound iron and nickel input transformers (switchable via push button), and comes standard with an iron core custom output transformer (optional custom nickel output is also available). When switching between input transformers the automute function engages to prevent loud pops or damage to speakers. Manual mute is also selectable. Pushbutton LEDs light up when selected. The Juggernaut is electronically discrete and fully class A; no opamps, no chips. Fully API (tm) comptible.

The Juggernaut was designed to be the ideal multi-tasker in the studio for any application. It is the first 500 series preamp that can provide a staggering range of tonal choices and control, through the use of switchable input transformers, widest choice of selectable impedance settings, onboard instrument DI, high-quality detented gain and impedance knobs for repeatability and stereo matching between multiple Juggernauts, and much more. The incredible amount of features packed into a single 500 series slot is unprecedented.

Some other unique features include "Boost" and "+THD". Boost control button lowers or raises the sensitivity of the INPUT to avoid the typical negative -20dB pad found on many preamps which effects the tone. The +THD button is -10dB OUTPUT pad which will allows slight saturation of the transformer.

The Juggernaut has a wide selection of impedance settings ranging from 300 to 10,000 ohms this feature acts like a "tone control" knob; going beyond the traditional idea of mic impedance matching with microphones. The lower settings allow for low end emphasis in the source, while the higher settings allow for a distinctly open and extended full range frequency response. The Juggernaut provides the utmost flexibility and freedom of choice.
