SALUT
Thank you for purchasing this Xaoc Devices product. Sopot is a triple summing
mixer featuring three signal-adding sections, with the middle one optionally
fed to the top and bottom ones. Sopot is a compact utility module useful in
summing multiple stereo and mono sound sources (up to four signals for each
section).
To better understand the device, we strongly advise the user to read through
the entire manual before use.
INSTALLATION
The module requires 6hp worth of free space in the Eurorack cabinet.
Always turn the power off before plugging the module to the bus board using
the supplied 16-pin to 10-pin ribbon cable, 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. Sopot is internally
secured against reversed power connection; however, flipping the 16-pin plug
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!
The module should be fastened by mounting the supplied screws before powering
up. However, before doing so, you may consider selecting the desired
attenuation in each of the three sections by appropriately setting the three
jumpers at the back. A detailed explanation of their function is provided
below.
MODULE OVERVIEW
Sopot features three independent summing sections A , B , C . Each section has four inputs 1 and one output 2 . The middle section, marked mix m A , may be optionally mixed into the upper one, mix l B , and the lower one, mix r C . Two 3-position switches 3 allow for including this additional submix in the upper and lower sections, or both (or neither). The switches offer three options: 50% attenuation, off, and 100% (no attenuation).
Each summing section features a soft clipping circuit to prevent unpleasant distortion. In addition, there is a signal level indicator 4 in each of the three summing sections. It shows the volume of the corresponding output using light intensity and color, gradually changing from green to yellow and red when the sum exceeds 16Vpp.
OPERATION
The main application of Sopot is combining up to four stereo sources (mix l for the left channel, mix r for the right channel) with up to four mono sources (mix m fed to the upper and lower sections). Depending on the position of the two switches, the middle section’s submix may appear in the stereo panorama as a centered source (100/100) or an off-centered one (100/50 or 50/100).
Sopot can also be used as three independent signal adders (both switches in
the center position for off) or for processing various control voltages thanks
to its DC-coupled signal path.
Please keep in mind that the signal amplitude in Eurorack is limited by the
dynamic range of op-amps to +/-10V, and it is physically impossible to sum
four hot signals without clipping. Therefore, Sopot can handle sounds that
mostly do not overlap (e.g., different voices of a rhythmic section). Still,
attenuation may be necessary depending on the application (e.g., mixing
continuous signals) and operating scenarios.
Attenuation may be set using three jumpers at the back of the module, one for
each section. No jumper means unity gain (1:1), while a jumper in place sets
the attenuation at -12dB (1:4). Please note that the jumpers adjust the
attenuation for the outputs of each section independently.
Even with attenuation set to 1:4, it is still possible to occasionally
overdrive a summing mixer when the incoming signals are sufficiently hot.
Therefore, each section features a special soft clipping circuit that offers
smooth saturation of the peaks. It is the same solution we used in our Tallin
dual VCA.
