Product Info
* Prices may vary. Check retailer for current pricing and availability.
The A-113 is a classic Doepfer module, and for good reason. It's a fantastic way to generate seriously deep and interesting bass sounds, especially when you're into textures and experimental tones. If you're building a modular system focused on low-end exploration, this is a must-have component.
Product Description
- Doepfer A-113
- Subharmonic Generator
- Derives four subharmonics from an incoming square wave signal

- Width: 26 HP
- Depth: 90 mm
- Power requirements: +120 mA (+12 V) / -10 mA (-12 V)
PROS

Frequently Asked Questions
Increasing the ratio lowers the subharmonic frequencies, resulting in deeper bass tones, but also potentially introducing aliasing.
Yes, it’s a standard Eurorack module with a standard power connector, but be mindful of its power draw relative to your PSU.
While other options exist, the A-113's straightforward design and Doepfer's solid build quality offer a reliable and characterful solution for subharmonic generation.
