Description

Technical Field

[0001] The invention relates to the technical field of mixing consoles, in particular to a microphone and speaker bidirectional transceiver mixing console. Background Art

[0002] A mixer is also called a mixing console. It amplifies, mixes, distributes, modifies the sound quality, and processes the sound effects of multiple input signals before outputting them through the master bus. Mixers are important equipment for broadcasting and recording programs in modern radio broadcasting, stage sound reinforcement, and audio program production systems. Mixers can be divided into analog mixers and digital mixers according to the signal processing method. Ordinary mixers need to be connected to microphones and speakers with dedicated audio cables to transmit signals. The storage and arrangement of cables, poor contact of cables, and wrong insertion of cable interfaces are the current functional deficiencies of ordinary mixers. Summary of the invention

[0003] The purpose of the present invention is to provide a two-way transceiver mixing console with microphones and speakers, which solves the problem that ordinary mixing consoles need to be connected with dedicated audio cables to transmit signals, and the problems of wire storage and arrangement, poor wire contact, and wrong wire interface insertion are the problems that are currently lacking in the functions of ordinary mixing consoles.

[0004] Technical Solution

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a microphone and speaker bidirectional transceiver mixing console, comprising a mixing console body, a lithium battery compartment is arranged inside the mixing console body, a 5200mAh lithium-ion battery is installed inside the lithium battery compartment, the mixing console body is wirelessly connected to a bidirectional transceiver module, a MIC2.4GHz pairing switch, a SPEAKER2.4GHz pairing switch and a charging compartment are arranged on the top of the bidirectional transceiver module, a multi-channel microphone pre-conditioning circuit is arranged inside the mixing console body, and a Bluetooth call function button, a DSP effect selection module with an LCD display, a USB sound card recording function selection module and a USB sound card interface are also arranged on the mixing console body.

[0006] Furthermore, the multi-channel microphone pre-conditioning circuit is used for microphone GAIN adjustment, EQ adjustment, and voltage limiting protection.

[0007] Furthermore, the Bluetooth call function button is used to connect to a Bluetooth mobile phone for calls and to play Bluetooth music.

[0008] Furthermore, the DSP effect selection module with LCD display screen is used for high-performance effect mode selection.

[0009] Furthermore, the USB sound card recording function selection module is used to connect to computers, tablets, mobile phone electronic products, and record sound sources such as microphones and musical instruments back to the computer.

[0010] The present invention provides a microphone and speaker bidirectional transceiver mixer, which has the following beneficial effects:

[0011] This microphone and speaker bidirectional transceiver mixer has a multi-channel microphone pre-conditioning circuit for microphone GAIN adjustment, EQ adjustment, and voltage limiting protection, etc.; it has an effect module with independent adjustment of DSP mode parameters and LCD screen display; it has a Bluetooth call function and can be connected to a mobile phone for live calls; it has an external independent sound card for high-definition audio recording and playback, and can be connected to a mobile phone by wire for communication; a 5200mAh lithium-ion battery pack can work for more than 6 hours for outdoor live broadcasts; a bidirectional transceiver module can simplify the wiring method and prevent incorrect connection, and can transmit and receive signals over long distances, which solves the problem that ordinary mixers need to connect dedicated audio cables to microphones and speakers to transmit signals. The storage and organization of wires, poor contact of wires, and incorrect insertion of wire interfaces are the current missing functions of ordinary mixers. BRIEF DESCRIPTION OF THE DRAWINGS
