Please check if you are using the Speaker output and find the little switch right below it with which you set the channel to be sent to the speaker. If you have issues with your mixer channels and the Main or Aux output, please get in touch with us via the e-mail address below.

The solenoid for the Field Kit can actually only move in one direction when it gets a pulse. It is pulled back to its starting position by the little spring around the actuator. So, naturally if the spring can‘t pull the actuator back it won‘t work very well.

Sometimes you can improve action by pulling the spring apart GENTLY or adding washers, so the spring has more tension and can push the actuator better.

The solenoid for the Field Kit can actually only move in one direction when it gets a pulse. It is pulled back to its starting position by the little spring around the actuator. So, sometimes the spring got a little bit loose or has a little bit too little tension to start with.

In that case, please check if the little nut on the actuator is tightened correctly. To further improve action you can adjust the spring tension by GENTLY pulling it apart or adding washers to one end, so the tension of the spring increases.

We tested the Signal Interface with some of the sensors that are included in the Arduino Sensor Kits that are widely available.

The Signal Interface is compatible with the following sensors included in those sets:

KY-001 Temperature sensor module

KY-002 Vibration switch module

KY-003 Hall magnetic sensor module

KY-004 Key switch module

KY-010 Optical broken module

KY-013 Temperature sensor module

KY-017 Mercury open optical module

KY-018 Photo resistor module

KY-020 Tilt switch module

KY-021 Mini magnetic reed modules

KY-028 Temperature sensor module

KY-031 Knock Sensor module

KY-033 Hunt sensor module

These jumper wires are useful to connect those sensors to the interface, just be careful to connect the wires correctly!

The DC Interface can provide up to 500mA of current at 9V before the fuse inside of the circuitry “trips”.

Don’t you worry though, the fuse is going to reset itself once normal operating conditions are met again!

The external devices that you are going to drive with the DC Interface should be designed to be operated under these limits (9V, <500mA), and everything should be fine.

Yes, we do. They can be found here.

First off, you need a Field Kit Eurorack Panel. Then, please follow these steps:

1) First untighten the nuts on the minijack connectors

2) Lift off the front panel to reveal the circuit board

3) Unscrew the four mounting screws on the corners of the circuit board

4) On the back of the circuit board locate the power jumper and swap it from PSU to EURO

5) Put the Eurorack panel on and tighten the hex nuts again

6) Attach the ribbon cable and watch out for correct orientation of the red stripe

7) You‘re good to go!

Also the Field Kit Manual has additional information about the process.

Yes, there is. We provide sets that include the wooden box, fronpanel, hex nuts, power adapter and mounting material. Please get in touch with us at the e-mail address provided below and tell us your shipping and billing address and we will be able to create an order for you.

First of all attach a spring tank and watch out for the jack colors to match the plug colors. The spring reverb doesn‘t work without a spring tank. Also, be sure to put your input gain knob where you want to have it (right below the spring tank connectors).

If you did that, here are some general purpose tips on how to get decent performance out of the Spring Reverb:

The FKFX Spring Reverb is designed specifically with Eurorack modular audio level in mind. If your audio source gives out Line Level signal, you should try to boost it before going into the Spring Reverb ( The Gain In provides up to +6dB / 2x gain to get you going! )

To further prevent noise-related issues with the Spring Reverb:

• Make sure no power-lines go close to the RCA-cables connecting the spring tank
• Make sure none of you patch-cables go close the RCA-cables connecting the spring tank.
• In extreme cases: you can split the ‘to’ and ‘from’-cables into separate lines to have better mechanical isolation.
• In even more extreme cases: sometimes, due to differences in studio environments, the former is not sufficient, and thicker gauge shielded cables might be needed. Experiment with heavy-duty shielded RCA-cables to see if it makes a difference!

Sometimes the RCA cables get a bit lose. The crazy noises come from the „collar“ of the connector losing contact with the RCA socket on the Field Kit FX. In that case take please take some small pliers and slightly and gently bend in the collars of the RCA jacks on the cable. This will cure your problem.

Please make sure your input gain is where you want to have it. You can find the input gain for the delay right below the 4th CV input jack and above the delay feedback knob.

First off, you need a Field Kit FX Eurorack Panel. Then, please follow these steps:

1) First untighten the nuts on the minijack connectors

2) Lift off the front panel to reveal the circuit board

3) Unscrew the four mounting screws on the corners of the circuit board

4) Gently pull the two circuit boards apart and locate the power jumpers. There is a little 3D printed plastic cap on top of them. Put all three jumpers from 9V PSU to Eurorack and put the little plastic cap back on.

5) Put the two circuit boards back together and watch out that all pins find their mating connector. Be careful that no pins miss their counterpart.

6) Put the Eurorack panel on and tighten the hex nuts again

7) Attach the ribbon cable and watch out for correct orientation of the red stripe

8) You‘re good to go!
