Frequently Asked Questions - Qx Quadrax Intellijel
What is the power consumption of the Quadrax?
The Quadrax draws approximately 100mA from the +12V rail and 20mA from the -12V rail. Always ensure your case's power supply can handle the total load.
Does the Quadrax work with the Qx expander?
Yes, the Quadrax is designed to work with the Qx expander which adds four additional gate/trigger outputs, one per channel. It connects via a 10-pin ribbon cable.
Can I use the Quadrax as an LFO?
Absolutely. Put any channel into Cycle mode (hold the Shape button until the LED blinks) to use it as a bipolar or unipolar LFO. The rate can be modulated via CV.
How do I update the firmware?
Download the latest firmware from the Intellijel website. Connect the module to your computer via USB (with the module powered in your case) and use the bootloader procedure: hold the Save button while powering up, then drag and drop the firmware file.
What are the different envelope modes?
The Quadrax offers AD (Attack-Decay), AR (Attack-Release), ASR (Attack-Sustain-Release), Cycle (LFO), Burst (triggered burst of pulses), and Hold (envelope held while gate is high). Each channel can be set independently.
Can I modulate the envelope shape?
Yes, each channel has a Shape CV input (with attenuverter) that morphs between linear, exponential, and logarithmic curves. There's also a global shape offset available via the menu.
How do I save a preset?
Press and hold the Save button (located on the right side) for about 2 seconds. The module will save the current state of all channels and settings internally. Up to 16 presets can be stored.
What is the maximum envelope length?
The attack and decay/release times can range from 0.5 ms to over 30 seconds (depending on the mode). The exact range is 0.5 ms to 32 s for AR mode.
Does the Quadrax have a trigger input for each channel?
Yes, each channel has its own gate/trigger input (marked with a triangle). Additionally, there is a global trigger input that can affect all channels depending on settings.
Can I chain channels for complex envelopes?
Yes, via the Menu you can set channels to trigger each other (e.g., channel 1 ends and triggers channel 2). This allows creating multi-stage or cascading envelopes without extra modules.
