Lauten Audio and Dr. Charles Chen Ph.D have filed for a patent relating to an invention, which allows for a balanced output directly from the condenser capsule.
The invention is based around a double-bias circuit for condenser microphone capsules that generate a balanced output directly from a condenser capsule with no need for a phase splitter or transformer in the circuit path.
“For the traditional single bias circuit, only one signal is retrieved from the capsule. To generate two balanced signals from the single signal, the options are to use an output transformer or a phase-splitter circuit in the case of a transformer-less design. The problem is these types of phase splitter circuits restrict the dynamic range allowed,” said Dr.Chen.
Lauten Audio is set to implement the new invention into future models of condenser microphones.
