Gozinta Description
The Gozinta is an input module capable of amplifying line level signals to Eurorack levels. The
2 independent channels have nominal 24dB gain and include front panel attenuators. Ultra-
modern amplifier ICs give this module excellent performance characteristics. Clip LEDs show
when output levels are about to clip.
The module can also be used as a utility amplifier for situations where processing has produced
low levels, such as when using a filter for percussion.
Also the module has good sharp clipping characteristics and produces interesting distortion
effects.
There are gain setting jumpers for each channel to configure gain to 12, 24, or 36dB. The
amplifiers are AC-coupled and are jumper selectable to DC
operation on each channel.
The Gozinta uses high performance LM4562 amplifiers which have excellent noise and
distortion specs, one of the best amplifiers available today. The Gozinta also boasts sealed
pots and enclosed jacks. No scratchy controls!
Examples:
Boosting levels of external equipment such
as MP3 players, CD players, computer
sound card outputs, and rack gear like
reverb units
Make-up amplifier for signals that are low
from processing or from patch issues like
low VCA output
When using a signal as a gate or clock but
the level is too low
Produces a clean distortion sound when
overloaded
This 4HP module has a maximum 20mA current
draw.
