Legendary symmetrical short ribbon design is incorporated into the FAT HEAD II Active/Passive
The FAT HEAD II Active/Passive ribbon microphone is a first for this type of design. This unique feature 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 will add up to 25db of gain, (this opens up the option to use this microphone with a wide range of preamps). The use of a very low noise differential amplifier circuit provides high gain while keeping the noise level low. We have optimized the circuit to preserve the warm, open, detailed tone of our Active/Passive ribbon mic by choosing operating conditions and electronic components that minimize tonal alterations. The discrete active devices in the mic are carefully matched for minimum distortion. By isolating the output of the ribbon from the microphone preamp the ribbon is consistently loaded at an optimal value resulting in less ribbon loading coloration. This set-up is extremely quiet and can handle 135 dB SPL. The Passive mode is best utilized with high gain preamps that are capable of powering the microphone with sufficient gain and eliminated the self noise that is usually evident in low gain preamps. Extremely long cable runs with minimal signal loss is possible due to the low-impedance output of the FAT HEAD II ACTIVE/PASSIVE, in addition, the ribbon element is resistant to damage by phantom power.
