Edit description

Unlock the potential of your modular setup with the Klavis Tweakers, a versatile Eurorack module designed for both seasoned synthesists and adventurous newcomers. This dual attenuator/verter, gain, and offset processor offers unparalleled flexibility with its two identical channels, each equipped with signal input and output, gain control, offset control, and an output selector switch. Whether you're looking to subtly shape your signals or completely transform them, the Klavis Tweakers provides the tools you need.

The module allows for creative signal routing, with Input A normalized to Input B, and Output A normalized to Output B, enabling operation as a mixer. This feature opens up a world of possibilities for signal processing, making it an essential addition to any modular synthesizer system. Despite its compact size, the Klavis Tweakers packs a punch, consuming a mere 24 mA on both +12 V and -12 V rails, ensuring minimal power draw while maximizing performance.

Key Features:

Dual attenuator/verter, gain, and offset processor
Two identical channels with signal input/output, gain control, offset control, and output selector switch
Input A normalized to Input B; Output A normalized to Output B for mixer operation
Current consumption: 24 mA (+12 V) / 24 mA (-12 V)
Width: 3 HP
Depth: 33 mm
