The Doepfer A-145-4 Quad LFO is a compact powerhouse designed to energize your modular synthesizer setup with versatile modulation capabilities. Perfect for both beginner and seasoned synthesists, this module introduces four independent low-frequency oscillators (LFOs) into your Eurorack, each boasting its own rate control. This flexibility allows you to craft intricate soundscapes by modulating multiple parameters simultaneously.

Each LFO in the A-145-4 can output both triangle and square waveforms, providing a palette of textures to shape your sound. With the added ability to tweak the frequency range via internal jumpers, you can explore everything from ultra-slow modulations at 0.002 Hz to fast-paced oscillations up to 50 Hz. This adaptability is complemented by the unit’s space-saving 4HP size, making it an ideal choice for those looking to optimize their rack space without compromising on functionality.

Notably, the A-145-4 features colored LEDs that offer a visual representation of each LFO’s frequency, adding an intuitive layer of interaction as you sculpt your audio landscape. Whether you're expanding an existing rig or building a new one from scratch, this module offers a nuanced modulation experience in a streamlined format.

Key Features:

• Four independent LFOs with individual rate controls
• Simultaneous triangle and square waveform outputs
• Default frequency range from 25 seconds per cycle to 50 Hz
• Expanded frequency range via internal jumper: 8 minutes per cycle to 2 Hz
• Space-efficient 4HP Eurorack module
• Visual frequency indication through colored LEDs
