Notes: TUL Dual Attenuator/-verter and Offset Generator

Temperature stable and accurate circuit design. The attenuator is exponential and can be regulated more precisely in the initial range.

As an attenuverter, the fader describes an S-curve, i.e. it is in Range +/- 0 finer adjustable. The AC gain is 1, so there is no loss at maximum Att/Attv settings.

The offset potentiometer shift by +/- 5 volts and can be switched to another mode on the back of the PCB using jumpers.

Here the attenuation is towards zero made until it is zero.

The normal mode leaves the voltage at the specified offset value.

Channel A is normalized to channel B so you can get two different CVs.

On the rear side of the PCB, you have a jumper to switch from offset pre fader (good for ADSR) and post fader.

Power consumption: +/- 20mA

Rackspace: 6HP

CV out is (-/+5Volt) if nothing is patched to IN A/B, so you can use it as a manual CV source.

Notes: Take up to two CV signals and this passive module converts them to TRS outputs in order to control effects pedal modulation inputs, with attenuation on both channels. Simple, straightforward stuff.

Supplier's Notes:
ADDAC309 CV to Expression allows a simple and straight forward connection between modular and effect pedals that features expression pedal TRS inputs.

Instead of using an expression pedal into the effects pedal the user can use this module in between a CV source and the Effects pedal to be controlled.

This is a great way to control the available parameters on the effects pedals straight from a CV source.

ADDAC309 features 2 channels each with a CV Input with attenuator and a 1/4" jack output.

This is a passive module, the power needed for operation is taken from the pedal power instead of the modular frame, this allows for perfect matching of the pedal's operating voltage which can range from 3.3v to 9v.

Notes: Need an offset voltage? Of course you do, you probably need one all the time, and you can never seem to find one. Well, here's two.

Yes, the Stereo Offset boasts not one but TWO linked offset voltages, and even better, they can be independently set as unipolar or bipolar with jumpers on the back of the module. To further aid your adventure in offsetting, bicolor LEDs will indicate the current state of both outputs.

Smoothly transition between voltages to simultaneously control other functions in your system, either by applying identical voltages to two different places, or by using simultaneous unipolar and bipolar signals for advanced control over your Eurorack system.

Do the right thing - get an offset generator you will love.

Notes: The CVADDER-HQ is a precision adder especially for adding 1V/octave (pitch-controlling) CVs. This makes it possible e.g. to transpose a sequence. Compared to general purpose CV mixers (like POLAMIX), this module does the summing of the CVs very precise (within a few millivolts), so the desired pitch is not affected.

The module offers four CV inputs where three of them are summed, and the CV at the fourth input is subtracted - meaning "transposition downwards".

This module also allows transposing the incoming CV by one or two octaves or a variable offset by buttons.

A separate output provides the voltage of the internal transposition (+1, +2 octaves / free).

If the transposition buttons are not necessary and you prefer to have a dual precision adder, take a look at the 2CVADD-HQ module.
