Notes: Originally designed for the Metropolix 1.4 MIDI update, the USB Extender extends the USB Micro connector on the back of a module, bringing it to the front panel for easy connection to your USB Host.

The 3U panel, includes a dual passive mult, which is great for splitting output signals to other modules. You can swap the panel with a Phillips-head screwdriver. The 1U panel does not have mults.

Also included is a 60CM Right-Angle Micro USB to Micro USB cable for routing the connection beneath the modules.

This module comes with a custom USB cable that connects on the back of the module to the Metropolix. The product comes with both 3U and 1U faceplates so you have the option to use it in either space.

Width: 2HP 1U / 2HP 3U
Depth: 40mm (with cable connected on rear)
Power: Passive

Notes: Switched mults come to Intellijel's space-saving 1U format, offering six jacks and two busses, routing signals between the two or muting them using three-position switches.

Supplier's Notes:
The Mult 1U takes one audio or CV signal input, and (mult)iplies to up to four outputs. Because the Mult is passive, it requires no power to operate. Multiply anything by four, twice.

A signal multiplier accepts an input signal and routes it to multiple outputs simultaneously. For example, you might want a sequencer's GATE to trigger two different envelopes - one to control volume and one to control filter frequency. In order to accomplish this, you need a signal multiplier.

In addition, each Switched Mult 1U features a pair of 3-pin Link connectors on the rear panel. These let you connect other 3-pin Link devices, such as an XY I/O 1U module, or even additional Switched Mult 1U modules (handy for distributing mults across the width of your case).

Notes: Tiny little low-pass gate in Intellijel's compact 1U format. Great value approach to this west coast classic module, based on a vactrol for that natural, organic sound.

Supplier's Notes:

Drop this module (or a few of them) into your 1U row, patch in some sound sources, and then ping them with gates and CV to get some instantly pleasing results. So simple and fun!

Natural dynamics with the magic of vactrols.

In general, low pass gates (LPGs) control the amplitude and timbre of a signal by opening and closing a low pass filter. When the gate is closed, no frequencies are allowed to pass through (and no output is heard). As the gate begins to open, the lowest frequencies pass through to the output. As the gate opens further, the output grows louder and its high frequency content increases.

Traditional Low Pass Gates use vactrols to control the opening and closing of the filter. Encased within a vactrol is both a light source and a light detector. Applying a control voltage to the vactrol lights its internal LED i the brightness of which is measured by its detector. What makes vactrols particularly unique (and well-suited to musical applications) is their non-linear response to voltage - in particular, the way in which the internal LED slowly dims (rather than shutting off instantly) when the control voltage is removed. This sonic coupling of timbre and volume, along with the circuit's natural decay, makes the low pass gate particularly adept at producing tones associated with struck objects, like hand drums or marimbas. Indeed, low pass gates are the main ingredient of the so-called Buchla Bongo sound.

The Intellijel Passive Low Pass Gate 1U is a simple, vactrol based, 1-pole, passive low pass gate, which is controlled by an external CV input. Without positive control voltage, the gate is completely closed and none of the LPG's input signal is passed through to the output. Increasing amounts of positive CV open the gate i making the output signal both louder and brighter. At +5V, the gate is fully open and the input signal is passed through to the output.
This makes LPGs sound very different (and more acoustic) than the traditional complement of envelopes, VCFs and VCAs that are employed in most subtractive synthesizers. Exciting the vactrol (via the CV input) with a trigger, noise blast, or short envelope will result in a very natural sounding filtered envelope that's reminiscent of the sonic characterics of struck objects, which are allowed to decay naturally.

In addition, because this is a passive circuit (no power is applied to it), its sonic characteristics are somewhat dependent upon the audio signal you feed into it, making it a very natural and organic way to shape a signal's volume and tone.

Pairs very well with the intellijel Shifty module to derive polyphony out of a only a few HP of modules.

Width: 6HP

Notes: Dual 4-way passive mult (one audio or cv signal in with multiple unbuffered outputs)

On the back of the pcb is a pair of solder points marked as "link". You can connect these (with a solder blob or small jumper wire) to turn the mult into a single 8 channel Mult instead of 2 x 4 channel.

Notes: Dual 1x5 Passive Multiple

Two rows of 1 x 5 Passive Multing

Notes: This module allows you to interface your Eurorack modular system to the pro balanced line level world (+4 dBu). You can send audio out to rack mount/desktop FX units, patch to external line-level instruments like synths and drum machines, interface to a DAW, and much more.

Features:

1 x Eurorack modular level signals to Balanced TRS 1/4? output path
Uses a high quality THATCorp balanced line driver IC
Output path steps a nominal Eurorack level (10 Vpp) down to +4 dBu with up to +6 dB gain.

Notes: This module allows you to connect balanced line level audio (+4 dBu) into your Eurorack modular system. It is a compact and easy way to patch in a rack mount/desktop FX units, external line-level instruments like synths and drum machines, outputs from your DAW, or many other line level sources.

Notes: Dual 1 x 4 buffered mult (one audio or cv signal in with multiple buffered outputs).

The output of the first mult is normalled to the input of the second mult to create a 1×8 buffered mult.

Notes: Att 1U Passive Variable Signal Attenuator

This passive attenuator has a 100K linear potentiometer that is DC coupled. Perfect for adding attenuators to those 1U/3U modules without.
