DoepferA-101-6 Opto FET Filter / Phaser

Doepfer A-101-6

The A-101-6 module features six -6dB filters all arranged in series. Each filter is capable of behaving independently as a low-pass, high-pass, or as one of the module’s two all-pass filters. These all-pass filters enable traditional phase-shifting in addition to more traditional filter techniques. 

A-101-6 Features

• Optical Voltage Controlled Filter using opto FET's 
• Low-Pass, Band-Pass, High-Pass, and All-Pass filter slopes available
• Circuit board jumpers for altering configuration and filter slope
• Faster response than vactrols which allows for quick vc response and FM capabilities
• Feedback chain can be variable and repatched for strange resonance effects
