Optx v2 is a pro-quality ADAT lightpipe converter for eurorack modular synthesizers. The DC-coupled module can encode and decode audio signals with extremely low noise, and CV signals with near-zero offset. Additionally, on-board sample clock allows for one-way ADAT output and the ability to be used standalone to interconnect eurorack systems.

Many computer audio interfaces are equipped with one or more pairs of ADAT expansion ports allowing for additional input and output channels. Optx v2 takes full advantage of these often unused ports, providing multi-channel connections directly to and from eurorack systems.

The module accepts any 8-channel ADAT encoded digital signal at the Rx TOSLINK jack (via lightpipe optical cable) and converts it into 8 discrete analog signals. Conversely, Optx v2 accepts 8 discrete analog signals and converts them into an 8-channel ADAT encoded digital signal available at the Tx jack.

When used in conjunction with software such as Bitwig Studio or Ableton CV Tools, Optx v2 is an excellent interface not just for audio, but also control voltages like 1V/oct pitch and gate signals, or LFOs, ADSRs and other modulators.

Optx v2 has been fitted with high-performance op amp input buffers and professional-grade Cirrus Logic analog-to-digital converters with extremely low noise and distortion, maximum dynamic range, and excellent overall detail. The inputs and outputs have very precise level scaling with a range of 20 Vpp (±10 V). Thus a typical eurorack audio signal of 10 Vpp will translate to exactly -6 dBFS, while maintaining an equal amount of headroom.

The module’s high-quality analog outputs, OUT 1-8, are DC-coupled and support both audio and CV (control voltage) signals at all times. The module’s analog inputs, IN 1-8, also accept both audio and CV signals. To ensure the best possible quality and precision, each pair of inputs has a front-panel switch that selects the conversion mode appropriate for each of these two signal types.

In AUDIO mode, the selected input pair is AC-coupled by enabling high-pass filters within the ADC. This guarantees that the audio signals are converted with no DC offset and the best possible signal-to-noise ratio. In CV mode, the selected input pair is DC-coupled, and CV signals are converted with accuracy and precision. When switched into CV mode, the input pair undergoes a self-calibration period of 5 seconds to detect and then actively correct any inherent DC offset.

Optx v2 also provides visual signal indication of the 8 decoded ADAT channels feeding the OUT 1-8 jacks. Each pair of WHITE LEDs indicates the polarity (-Ve left, +Ve right) and relative strength of the signal (±10 V). Audio-rate signals will generally light both LEDs continuously, whereas LFOs will alternate more apparently between the two. Gates, triggers and positive-going envelopes will generally light only the right LED (+Ve).

Features

• Bi-directional ADAT lightpipe encoding/decoding of 8 analog inputs/outputs
• Switchable input mode (in pairs) powered by high-performance Cirrus Logic converters
• AUDIO input mode ensures the highest fidelity possible with ultra-low noise
• Self-calibrating CV input mode provides exceptional accuracy and near-zero offset (DC-coupled)

Standard Mode – Send two channels into your USB device and receive two channels from USB.

Insert Mode – Send two channels to your USB device and get a copy of the sent signal in the outputs.

Toggle between the modes via a pair of jumpers on the back.  The USB-B to USB-A cable is provided with the module.  Why use the cutting edge USB-B?  I felt the jacks were way more sturdy than mounting USB-C jacks vertically.

Expandable – Bartender, Barbacks, DVCA, Cast Iron, Mingles, and USB-2CH can all be connected with Dupont cables (aka female to female breadboard cables) via pin headers on the back of the modules.  Connecting the in and out pins will send/receive the audio into the next module.

Ciao!! is a compact and performance-oriented output module built with high-quality, low-noise components and layout for the best possible modular-to-line level conversion. It features 2 stereo line outputs, a headphone amplifier, and has a few tricks up its sleeve.

Better sound quality for cleaner recordings

Stereo pairs A and B each have dedicated level controls with signal indication and possible clipping warnings for the line input you are sending to. Channel A is equipped with 6.3mm (¼”) balanced jack outputs to minimize noise and ensure maximum quality when delivering to the sound system. Channel B outputs through a 3.5mm (?”) stereo jack, which can also serve as an additional headphone output. The dedicated headphone output provides high output power and includes a selection switch for listening to either A or B channels.

Smart signal distribution

The normalization of inputs makes it easier to distribute signals to some or all of the outputs. The MIX switch can blend Channel B into Channel A in stereo, opening up the module for several useful performance scenarios, such as pre-listening or simple stereo mixing.

Features

• 2 stereo channels A and B
• Channel A output features 6.3mm (¼”) balanced jacks
• Channel B output features 3.5mm (?”) stereo jack
• Dedicated level controls for each channel
• Signal indication with line-level clip detection
• Clever input normalization
• Headphone output with a channel-select switch
• Stereo mix switch to mix Channel B into Channel A
• Back jumper for customizing the normalization path

Fortunately for the budget-conscious musician, Eurorack modules and stompboxes have always existed in separate worlds — someone whose Eurorack system consumes an entire wall in their home is usually not the same person whose pedalboard now requires a dedicated roadie just to transport it to the gig.

Intellijel’s Stomp removes the barrier between Eurorack and stompbox. It provides the modular synthesist with a portal to stompbox nirvana, and the guitarist with a wormhole to the sonic manipulations of Eurorack modules.

Stomp enables the modular synthesist to interact with the impressive assortment of delays, choruses, flangers, phasers, fuzz boxes, tremolos, wah-wahs, amp simulators, compressors, and pitch shifter pedals available to guitarists. If your effects pedal is adorned with an expression pedal input, Stomp supports that too, and even features a built-in LFO to modulate your pedal’s expression input. Need something crazier? No problem. Simply patch any modulation source from your modular system into the expression control jack to override the built-in LFO.

Conversely, guitarists can plug their guitar directly into Stomp’s RETURN jack, giving them access to the myriad filters, ring mods, wavefolders and — most importantly — the near-infinite CV modulation delights inherent in Eurorack.

Features

• Robust Neutrik 1/4″ TS connectors for the SEND/RETURN and TRS for the Expression interface
• Signals arriving at Stomp’s RETURN jack pass through a Class A triode emulator, allowing for some tube-like overdrive at high gain setting.
• Stomp is more than just a simple level shifter — it’s also an impedance converter, which provides proper drive and loading for any FX pedals or instruments you connect.
• Separate gain controls on both the SEND and RETURN. This enables you to adjust the level of any audio being sent to the FX pedals as well as any audio coming back into the modular. Not only does this allow you to optimize the signal-to-noise ratio, but by significantly boosting the RETURN level, you can achieve some pleasingly overdriven tones.
• Supports both Instrument and Line levels via a front panel switch.
• Use Stomp’s RETURN circuit as a “direct box” for connecting any instrument.
• The high input impedance of the RETURN circuit allows it to be used as a piezo pickup preamp for acoustic instruments.
• Use Stomp in the studio as an active “re-amping” device to play pre-recorded tracks back through guitar amplifiers or pedals.
• All inputs are protected for minimum RF interference.
• Return signal can be phase inverted for use with those pedals or effects types that invert phase.
• Low MIX output impedance for driving long cables, lower noise, and minimum interference from outside sources.
• The Expression Pedal Output converts analog CV sources (or the internal LFO) into an output compatible with most stompbox Expression inputs.

Specifications

• Width: 8hp
• Depth: 35mm
• Power: +47mA / -13mA
