Dual Attenuverter / Offset

DOA is an easy to build Thonk utility. Scale, invert and offset your control and audio voltages to dial in precise modulation. Designed in-house at Thonk.

The t02 DOA is a dual 4HP DIY Eurorack attenuverter & offset module. Scale, invert and offset your control and audio voltages to dial in precise modulation. The DOA features two identical channels with bipolar LEDs to indicate the polarity and amplitude. The input signal travels first through the attenuverter stage, then the offset is added, so changing the offset will not affect the attenuversion. Both inputs are normalled to +5V, so that when nothing is patched in, the bigger knobs works as an offset between -5V & +5V. If the output of channel A is left unpatched then the signal is mixed into channel B.

Features:

• Attenuation and inversion of control voltages
• DC offset +/-
• Two channels for dialling in precise modulation
• LEDs to indicate amplitude and polarity
• You can never have enough atten, invert & offset!

Specs:

• Width: 4HP
• Depth: 25mm (including power connector)
• Power: +12V 15 mA, -12V 11 mA
• Designed in-house at Thonk
