connected and/or powered and after they completely cool down after use for at least 30 minutes.
2. WHAT IS 333
The 333 is an analog summing and distribution module for eurorack modular systems. It is composed of three identical sections,
each of those comprising an high quality summing amplifier with 3 inputs, and three independently buffered outputs.
The summing amplifier circuitry and the system optimization are derived directly from the CGM creative mixer series, with the
additional ability to handle signals starting from DC.
3. CONNECT THE POWER!
Before to connect the power cable, pay attention to:
•the power connector on the module is the keyed one in the top;
•the red line on the cable should be placed matching the -12V side on your power board:
please double check with your power boar supplier that the marked side is the -12V.
WARNING: Frap Tools can not be held responsible in any way for problems or damage to
persons or property or to the device itself, if the device is not connected as indicated above.
3.1. Warm-up and working temperature
For best performances, we suggest to let the 333 warm up around 15 minutes prior
to use it [tested at 25°C]. It is absolutely normal that it feels warm when using it!
4. MOUNTING THE MODULE
After connecting the power as explained in the previous section, install the 18HP modules in your case using the 4 screws provided
you prefer, being sure the module is safely and tightly connected to your eurorack case.
The 333 module use the standard eurorack orientation, red line is -12V. Please double check with the power system you want to
use that both uses the same powering system.
WARNING: Frap Tools can not be held responsible in any way for problems or damage to persons or property or to the device itself,
if the device is not connected as indicated above.

5. FEATURES
The 333 is based on a very simple approach: it is composed of three identical section, red, yellow and green. Each of those section
sums up to three signals, the one plugged to any of its three inputs, and distribute this sum to three independently buffered outputs.
The first input of yellow and green sections (the one in the top) is semi-normalled to the after switch sum result of the previous
section (so the yellow to the red, and the green to the yellow).
All the inputs are DC coupled, so you can use each section to sum audio signals, control voltages as well as merging clocks.
Using the -6dB (-50%) attenuation switch you can attenuate all these signals, independently on each section. !
