Tama 12TM
Thank you and congratulations for your purchase of
the Hexdevices Tama12TM Module! That was a smart
move. You are now the owner of a 12db pure analog
lowpass filter, with crazy resonance harmonics.
The brain inside the shell
This filter is based on transconductance amplifiers and it’s a
pure analog second order lowpass filter.
How to use (Check modular pic.)
A. INP: Stands for the line input of the module. With the use
of a 3.5mm TS mono jack, you can plug any of your audio
sources into the module. Input impedance is 200kΩ.
B. FRQNC: The frqnc is the cutoff frequency knob.
By doing changes to this knob you actually change the
cutoff frequency.
C. RSNC: This knob sets the resonance level of your sound.
As you increase that, you increase the sound level of your
cutoff frequency. And by turn it to maximum you force the
filter to self- oscillate.
D. LPOUT: This is the line out of your lowpass filter. With the
use of a 3.5mm TS mono jack you can take your out-pro-
cessed signal.

E. CVIN: Is the control input for the cutoff frequency. By using
a 3.5mm TS mono jack you can insert a signal (5Vp-p) from
an external source and manipulate the cutoff frequency of
you module.
Extra info
As a 12db filter the slope is pretty gentl. Also keep in mind
that OTAs are temperature sensitive components so, the be-
have of your filter may varies as the time pass.
In the back side of the module can be found 4 different trim-
mers and their names are lockated on the board. The first
called “INLVL” is to control the input signal level, in order to
avoid overdriving the filter and achieve minimum distortion. Or
overdrive it, to unlock the secret harmonics of the most ag-
gressive filter you ever had. The second is called “EndPoint” it
controls the amount of frequencies that can pass with the cut-
off knob completely closed and customise your cutoff knob
behaviour (3.3kΩ- suggested value).
The Third is called “CVCTL” and is used in order to control the
high – low frequency limits of the filter when you control it
from an external source. Last but not least the fourth trimmer
is to control the output signal level for i/o leveling matching or
more aggressiveness and distortion (OUTLVL).
