Intellijel

Notes: Sometimes your ears are not enough and you really need to see the sounds and control voltages you are generating. Zeroscope's two channel design lets you display and compare both control voltages and audio. It's a good old fashioned sci-fi light show!

The Zeroscope 1U is an adaptation of the excellent 3U Zeroscope by VPME.DE.

Three Modes Packed Into 1U:

- Scope: Standard graphical display, with time displayed on the X-axis and voltage displayed on the Y-axis.
- X-Y: Alternate graphical display with CH 1 driving the X-axis and CH 2 driving the Y-axis.
- Tune: Alphanumerical tuning display, which you can configure to show either Hz values or note names.

The Scope displays have adjustable display offset for each channel and an adjustable trigger threshold, while the tuner has options for reference pitch and average update speed.
Ins & Outs

The inputs are DC coupled and accept signals between -10V and +10V. The Signal on the input is normalled to the output below; this allows you to monitor or tune a signal without a mult or re-patching.

Notes: Get Amped

Amps comprises two precision linear VCAs that have been carefully designed to offer a wealth of flexibility and additional functionality. The front panel controls and signal normals allow these two VCAs to also be configured to function as: line level boosters, crossfaders, ring modulators, mixers, and much more. They can also be chained together by way of an included cable to form larger, more complex systems.

Amps features cascaded CV inputs and cascaded mix outputs allowing it to be used in a number of versatile configurations. A boost switch enables you to amplify each VCA's input by either +6dB or +20dB i ideal for boosting low amplitude signals or pleasingly overdriving audio. The addition of a phase inversion switch for the second channel allows Amps to function as a ring modulator. The CV normalization, which can also be inverted and offset, also allows for VC-Crossfader functionality.

Features

Manual LEVEL slider per VCA i convenient when using the module as a mixer, or for biasing the signal for CV (such as when modulating the VCA with a bipolar LFO).
Dedicated CV attenuators with dual color LEDs for monitoring bipolar CV signals.
Linear response curve.
Input and CV normalling of VCA A to VCA B to allow a single source to feed and/or control both VCAs.
Output normalling of VCA A to VCA B to allow both VCAs to feed a single output.
Each VCA has a boost switch that can increase the output level by either +6dB or +20dB.
Phase Invert switch on VCA B allows for ring modulation capabilities.
CV Invert switch on both VCAs allows for crossfading one signal into another.
4-pin link connectors on the rear panel allow for multiple AMPS modules to be chained together to create a 4-channel mixer; 6-channel mixer; etc.

Notes: SVF 1U

Multimode State Variable Filter

The perfect 1U, multimode, voltage-controlled filter for sweet-sounding subtractive synthesis duties or to form the basis of more complex patches. Punchy, clean, and precise. Explore new sounds through the dual modulation inputs and dedicated low pass, high pass and band pass/notch outputs. This filter responds beautifully to audio rate FM and you can self-patch to get even more interesting filter responses. Adjust the Q for a sharp howl or use it as a sine VCO.

Features:

Dedicated 2-pole Low pass filter (LP) and 2-pole High pass filter (HP) outputs.
Switchable Bandpass filter (BP) and Notch filter (N) output.
Optional +6dB input boost and asymmetric clipping circuit.
PITCH input tracks 1V/Oct accurately over 4+ octaves.
FM CV input with attenuverter.
Capable of generating very low distortion sine waves from 2Hz to 20kHz when driven to self oscillation (Max Q).

Power: 27mA @ +12V 30mA @ -12V

Notes: Triplatt is a three-channel active/buffered attenuverter and summing mixer. Each channel has a knob, which can function as a unipolar attenuator or a bipolar attenuverter, depending on the setting of its corresponding two-position polarity switch.

Each input is normalled to a built-in precision +5V DC voltage source. With nothing plugged into the jacks, each knob controls a voltage range of 0 to +5 V or -5 to +5 V depending on the position of the channel polarity switch. Outputs A and B are also capable of a range of 0-10 / -10 to +10 when using the special function switches.

Each output is normalled to mix into the output of the channel below, making it possible to do sub mixes in groups of two or three.

In addition, each channel has a "special function" switch to alter its input voltage in a specific way. Channel A has a 2x voltage multiplier switch, allowing you to double the voltage sent into Channel A. Channel B has a +5V switch, allowing you to add 5V to whatever voltage is sent into Channel B. Channel C has a mute switch, allowing you to completely turn off the signal being sent into Channel C.

Notes: Outs enables your modular system to output both professional and prosumer compliant audio, and send it to external amplifiers, mixers, recording devices, or DAW interfaces. Using the L+R Level knob, it scales modular-level voltages down to the level required to drive external gear at either the +4dBu balanced professional line-level standard or the -10 dbV unbalanced standard.

Headphone monitoring is also provided via a low noise built-in headphone amp (with its own independent level control), capable of driving a wide range of impedances - from studio grade headphones to portable style earbuds.

To use Outs, simply connect the final output of your patch to the 1/8" inputs (where the built-in activity LEDs light up to indicate the presence and intensity of the input signal). The left input is normalled to the right, so you can create a stereo signal from a mono source. Or if you have an Intellijel Mixup, you can remove a jumper from its rear panel, and connect it to the Outs module using the 3-pin link cable included with the Mixup.

Notes: Mighty oscillations, mini size.

An analog oscillator and LFO with pure waveforms and precise tracking in a compact package. Perfect as a utility modulation source but equally capable to be used as a primary sound source. Patch it up and let it rip!

PITCH knob has three octave range in VCO mode (extended to seven with the octave switch) and seven octave range in LFO mode (extended to 11 with the octave switch).
Bicolor led indicates the state of the triangle core rate

Notes: This is the version II of the original uVCA.

This module was adapted from a design by David G. Dixon

Notes: Mixup is a versatile, expandable audio mixer for Eurorack format. It has eight inputs (6 on the front panel) and two outputs. Inputs 1 and 2 are single-channel mono inputs, each with its own mute switch and level control; Input 3 is a dual-channel stereo input with a shared mute and level control; and input 4 is an auxiliary unity-gain, non-mutable stereo input.

Using bus connectors on the back panel, you can chain multiple Mixups together in series, giving you the ability to mix together even more inputs, or to create sub-mixes for routing around larger systems.

Because Mixup is designed specifically for audio (and not for CV mixing), it uses AC-coupled circuitry (which reduces the potential for 'pops' when muting and unmuting audio), and it uses audio-grade, logarithmic attenuators for a smooth, even response across the entire volume range.
