7 ULTRA-G GI100 User Manual
The GI100 features a switchable speaker simulation, developed in collaboration with
renowned amp designer Jürgen Rath, which adds the sound of a 4 x 12" cabinet to your
direct guitar signal at the touch of a button. Analog speaker simulations, oering the
possibility to get a typical guitar cabinet sound to tape or to a PA without the necessity of
cabinets or microphones, have been available since the mid-80’s. Since then, the appeal of
“instantsound” via simulation as a means of reducing equipment and hassle has continuously
grown. Havingdeveloped a great deal of convincing guitar gear with various manufacturers,
Jürgen Rath was an obvious choice for us in developing our VIRTUAL 4 x 12" CABINET
speaker simulation. In the words of Germany’s top specialty publication GITARRE&BASS,
“The Virtual Cabinet delivers an authentic 4 x 12" simulation with impressive sound,
cuttingpower and clear reproduction.” (MichaelDommers,8/97)

(1) The VIRTUAL 4 x 12" CAB speaker simulation can be switched on and o with the
SIMULATOR ON/OFF switch.
(2) When activated, the GND LIFT breaks the ground connection between input and output.
Depending on the grounding of the connected equipment, thiscan eliminate hum or
ground loops.
(3) OUTPUT TO MIXER is the GI100’s balanced, mic level output. Useahigh-quality,
balancedXLR (microphone) cable to connect the ULTRA-G toaconsole.
◊ You should never connect pins 2 or 3 with pin 1 or remove the shield from pin 1.
Otherwise, it will not be possible to operate the unit with phantom power.
