zerosum inertia zi52 price : $500.00

the zi52 is a recreation of the metasonix r52.
this is a zerosum inertia product with permission granted from metasonix.
metasonix wants it clear that zerosum inertia is responsible for the questions, support and manufacturing of the product.

it is a resonant equalizer/resonator/filter useful for tone sculpting and scream generation when at high resonance settings.
two 12aw6 pentodes are responsible for the character of the sounds processed and created.
12aw6 have an amplification factor of 42 mu compared to 36 that a 12au6 provides.
the 12aw6 has a distinct resonance tone that is not found with a 12au6.
it is fizzley and sounds like a fuzzbox at max resonance.
backing off the resonance allows for smooth filtering without oscillations or squeals.
the resonance is technically a gain function and needs to be up a bit for sound to pass through.
the input knob affects the resonance behavior and general overal sound of filtering heard.
to hear the filtering effect, backing counter clockwise on the input level is needed.
increasing the input level creates more saturation but overloads the filter and less "filtering" is heard.
recommended to start about 2 o'clock.
turning input level knob is just as important as the resonance.
lower input levels is more extreme.
it is recommended patching a vca in front of the audio input for dynamic control.

color knob morphs between bass and treble frequency filtering.
the switch below the color knob provides more treble tonal shaping by inserting a .0033 polypropylene capacitor into the signal path.
these two control used together set the initial frequency range of the sounds you want to accentuate or filter.

this is the color of the sounds. sweep knob sweeps the filter. this is where the movement of the sound happens.
the jack below is the control voltage input to get the movement happening with lfos, envelope generators, sequencers and rhythmic pulses.

scream knob controls the resonance.
higher settings result in oscillations and screams.
lower settings for reduced oscillations.
about 3'clock provides smooth filtering without shrieks or screams.
