INSTALLATION
This module is designed for use within an Intellijel-standard 1U row, such as contained within the Intellijel 4U and 7U Eurorack cases. Intellijel’s 1U specification is derived from the Eurorack mechanical specification set by Doepfer that is designed to support the use of lipped rails within industry standard rack heights.
Before You Start
Intellijel Eurorack modules are designed to be used with a Eurorack-compatible case and power supply. We recommend you use Intellijel cases and power supplies.
Before installing a new module in your case, you must ensure your power supply has a free power header and sufficient available capacity to power the module:
- Sum up the specified +12V current draw for all modules, including the new one. Do the same for the -12 V and +5V current draw. The current draw will be specified in the manufacturer’s technical specifications for each module.
- Compare each of the sums to specifications for your case’s power supply.
- Only proceed with installation if none of the values exceeds the power supply’s specifications. Otherwise you must remove modules to free up capacity or upgrade your power supply.
You will also need to ensure your case has enough free space (hp) to fit the new module. To prevent screws or other debris from falling into the case and shorting any electrical contacts, do not leave gaps between adjacent modules, and cover all unused areas with blank panels. Similarly, do not use open frames or any other enclosure that exposes the backside of any module or the power distribution board.
You can use a tool like ModularGrid to assist in your planning. Failure to adequately power your modules may result in damage to your modules or power supply. If you are unsure, please contact us before proceeding.
Installing Your Module
Once connected, the cabling between the module and power supply should resemble the picture below:
Before reconnecting power and turning on your modular system, double check that the ribbon cable is fully seated on both ends and that all the pins are correctly aligned. If the pins are misaligned in any direction or the ribbon is backwards you can cause damage to your module, power supply, or other modules.
After you have confirmed all the connections, you can reconnect the power cable and turn on your modular system. You should immediately check that all your modules have powered on and are functioning correctly. If you notice any anomalies, turn your system off right away and check your cabling again for mistakes.
FRONT PANEL
Controllers & LEDs
[A] FSR – The surface of the force sensing resistor is both touch and
pressure sensitive.
Touching it sends a +5V signal to the GATE [2] output for as long as your
finger sits on the pad.
Pressing it sends a voltage to the CV Out [1], whose value corresponds
with the amount of pressure you apply. At maximum pressure, +5V volts is sent
to the CV Out [1] jack.
The pad is very sensitive and offers a great deal of nuanced, real-time
control.
[B] CV LED – This LED begins to glow when the FSR [A] is being touched, and gets brighter as more pressure (and thus more voltage) is being sent to the CV Out [1] jack.
[C] GATE LED – This LED lights when the FSR [A] is being touched and a +5V gate signal is being sent out the GATE [2] jack.
Inputs & Outputs
[1] CV out – This jack outputs a voltage that corresponds to the pressure with which you press on the FSR [A]. Pressing very lightly sends voltages near 0V. Maximum pressure outputs +5V.
[2] GATE out – This jack outputs +5V gate signal for as long as the FSR [A] is touched, returning to 0V when you lift your finger off the pad.
