Fat Head II Active-Passive

Common name: Cascade Microphones Fat Head II Active/Passive

Production Status: In production

The Cascade Fat Head II ActivePassive ribbon microphone allows the user to have the option to switch between either mode with a simple flick of an internal switch. The Active mode requires phantom power and adds up to 20db of gain. The Fat Head II Active-Passive uses a very low noise differential amplifier circuit to provide high gain while keeping the noise level low. The active devices in the mic are factory matched for minimum distortion. The active portion of the Fathead II Active-Passive ribbon microphone is a carefully adjusted differential cascade JFET amplifier where the phantom power supply 6K81 current limiting resistors are used as the cascode stage drain load resistors. After the cascode amplifier the ribbon is interfaced through a 1:37 Lundahl LL2913 transformer. The switch provides either the transformer output signal directly or the further active amplified signal to the XLR connector on the mic. The Fat Head II Active-Passive comes with a premium suspension mount, a padded storage pouch and aluminium case.
