The A-174-2 is a solid, no-frills controller module for Eurorack. It's a great option for those wanting a straightforward way to add modulation without a ton of extra complexity – especially useful for beginners getting their feet wet with modulation routing or those needing a compact solution. It’s a workhorse module, reliable and consistent.
Product Description
- Doepfer A-174-2
- Module
- With two modulation wheels
- The factory setting is a spring loaded wheel on the left side with bipolar voltage output (i.e. 0V in the centre position
- positive voltage in the upper range
- negative voltage in the lower range; voltage range approx. -5.5 V ... 0 V ... +5.5 V)
- The wheel to the right side is without spring and has a positive voltage output (i.e. 0V in the lowest position and positive voltage when operated upwards; voltage range approx. 0...+8 V)
- For the spring loaded wheel a voltage "plateau" around 0 V is the preset
- so the output voltage is always 0 V in a small range near to the centre position
- Width: 14 HP
- Depth: 40 mm
- Power requirement: +10 mA (+12 V) / -10 mA (-12 V)
PROS
- • Spring return offers expressive, nuanced modulation possibilities
- • Two distinct CV outputs expand modulation routing options
- • Compact 14HP footprint maximizes space in modular setups
- • Robust Doepfer build quality ensures long-term reliability
CONS
- • Spring action can be a bit unpredictable for precise control
- • Limited voltage ranges restrict extreme modulation depths
- • The positive-only output lacks versatility for negative modulation

Frequently Asked Questions
The spring return provides a tactile feedback and a natural 'resting' position, but can introduce slight inconsistencies in voltage output if not carefully calibrated.
No, the positive-only output is strictly 0V to +8V; you'll need to use the bipolar output for negative modulation or use an inverter elsewhere in your system.
Absolutely; the two different outputs allow for experimenting with basic and more complex modulation techniques without needing multiple modules.
