TIMISZOARA
SAluT
Thank you for purchasing this Xaoc Devices
product. Timiszoara is a stereo, Eurorack com-
patible, voltage-controlled multi-effect signal
processor based on the popular Spin Semicon-
ductor FV-1 DSP chip. It features a full stereo
signal path with two adjustable audio inputs,
two outputs, and a stereo voltage-controlled
wet/dry mixer. In addition, there is a microSD
memory card slot on the front panel that allows
for loading factory and custom effects without
any restrictions or copyright protection, which
means you can use many effects available on
the Internet and even create your own.
Effect programs are organized in banks of
8 and can be selected using a rotary encoder,
as well as CV and trigger signals. Timiszoara
features a crisp OLED screen that displays the
program parameters and its name. It also
facilitates navigating the list of banks. Up to
three parameters per effect can be controlled
from the front panel with illuminated slider po-
tentiometers and dedicated CV inputs.
InSTAllATIOn
The module requires 10hp worth of free space
in the Eurorack cabinet. Always turn the pow-
er off before plugging the module to the bus
paying close attention to power cable pinout
and orientation. The red stripe indicates the
negative rail and should match the –12v
mark on the bus board and the unit. Timiszo-
ara is internally secured against reversed
pin header may cause serious damage to
other components of your system because
it will short circuit the +12V and +5V power
lines. Always pay particularly close attention
to the proper orientation of your ribbon cable
on both sides! note: There is a second, 10-pin
header at the back of the module for connect-
ing an expander. do not plug power into
this header, as it will destroy your
module!
The module should be fastened by mounting
the supplied screws before powering up. To
better understand the device, we strongly ad-
vise the user to read through the entire man-
ual before use.

1. The OLED screen 1and the single rotary
encoder 2allow easy navigation between
the effect programs organized into banks
of 8. The banks are loaded from the microSD
memory card inserted into the slot 3. During
normal operation, the screen displays the
name of the current effect and the names of
its three parameters.
Two inputs below the rotary encoder allow
for remote changing of the programs within
the bank:using continuous CV plugged to the
scan input 4and using trigger impulses via
the next input 5.

an emergency such as a faulty or lost mem-

The three parameters of the current effect
program may be controlled manually or with
control voltage patched into a jack above each
corresponding param slider potentiometer.
The CV inputs accept 10Vpp. With the slider
in the middle position, an incoming ±5V LFO
sweeps the entire range. Likewise, with the
slider set at minimum, a 10V envelope sweeps
the entire range. The same rule applies to the
mix potentiometer and its CV input.
Selecting programs from the current bank
is performed either with the rotary encoder
knob, or externally with CV and/or trigger.
Feeding a trigger to the next input has the
same effect as turning the encoder CW and
pressing it. In other words, the next program

voltages in the range of -5V to +8V, and each
change by 1V causes a switch to the next
position above or below the current one. Re-
moving the cable is equivalent to plugging 0V
which means the selection returns to the state
from before the application of CV control.
note: The FV-1 chip needs a moment to load
each new program and re-initialize its inter-
nal state; thus, programs cannot be scanned
instantaneously.
SOund QuAlITY cOnSIdeRATIOnS
Timiszoara has been designed with great care
taken to provide high audio quality. Audio-
phile-grade op-amps handle the entire signal
path while the digital section is separated from
the analog one. The FV-1 DSP features 24-bit
sampling rate which means the effective signal
bandwidth is slightly limited. Since modular
signals often contain very high frequencies,
special care has been taken to avoid aliasing by
Please note that FV-1 operates on a low level
signal; hence a particular gain staging had
to be applied. The signal must be strongly at-
tenuated internally before the DSP and then
always brings up some noise, and if your pow-
er supply is very dirty, it may affect the output
audio. We do not recommend using switch-
ing-type regulators as a linear PSU is always

modules introduce digital noise to the GND rail
keeping the common resistance as low as pos-
as they invite noise and interference between
modules.
Avoid feeding very quiet signals to your Ti-
miszoara and amplifying the output signal to
compensate. Conversely, observe the adc clip
indicator to avoid overdriving the unit. Use
input attenuators to adjust the signal’s am-
plitude and keep in mind that some program
algorithms may cause internal clipping. In
general, it is physically impossible to prevent
distortion when a loud continuous signal is

fAcTORY PROGRAMS
Timiszoara comes with a microSD card hold-
ing factory programs covering a wide range
pitch shifters, distortions, glitching, and stut-
tering. Many of these effects perform in stereo
from utilizing most of the resources for a sin-
gle signal path. In such a case, the program
downmixes the stereo signal to mono before
processing. Keep in mind that the total amount
of memory in the FV-1 chip allows for only one
second of delay, which must be split between

channels. Though, some included combo
programs feature a different effect in each
channel.

We have prepared quite a few banks of algo-
rithms that cover most effects needs: delays,
-
ever, we wanted to ensure that users had ac-
cess to some more adventurous programs, so
we created the following banks to allow you
to take a walk on the wild side.
glitch includes algorithms emulating var-
ious dirt-inducing glitching behaviors such as
a skipping CD, bit reduction, dropouts, and
other digital signal degradation gems.
deconstr and reconstr are two banks
especially suited for the brutal destruction of

woven feedback paths, extreme gain values,
oscillations responding to the dynamics of
the incoming audio—all that and more.
reverbs2 is a bank of of reverb effects
with a twist. These programs are much more
‘out there’ than the customary programs in-
cluded in the reverbs1 bank, which means
more modulation, more size, and even more
modulation!
parallax is a bank of delays featuring
two parallel delay lines with various feed-
back paths, thus offering different time-man-
delay time and feedback, our parallax delays
have a third parameter called skew that ad-
justs the time displacement of the two delay
lines with regard to one another.
resonator is a set of resonator algo-
rithms covering all the bases, from subtle to
-
gle-voice and minor/major chord varieties.
ringmod does what it says and includes
stereo, controlled by an envelope follower,
and cross-modulation—we’ve got you cov-
ered. Release your inner Dalek!
