More Information
Summary:The invention relates to a multi-sound source recording module and an application method thereof. The recording module utilizes the original output port of a recorder to form sound source control port(s) with the number one-to-one corresponding to that of sound source device(s), and realizes control of operations of different microphones by using different sound source control ports to output bios voltage MicBias through the isolation effect of capacitors, so as to dispense with a special switch component and save switch cost on the premise of ensuring the recording effect. The recording module can also realize the multipath sound mixed recording function which can not be realized in the original design.
