Abstract

The invention discloses a bidirectional audio signal converter, and the converter comprises a shell, an analog-digital conversion part, a digital-analog conversion part and a clock part; the analog-digital conversion part, the digital-analog conversion part and the clock part are arranged in the shell, and the analog-digital conversion part comprises an analog input part, an analog-digital conversion part and a digital output part which are connected in sequence; the analog input part is used for inputting a level signal, the analog-to-digital conversion part is electrically connected with the analog input part and is used for converting an analog signal into a digital signal with independent word clock, bit clock and data, and the digital output part is electrically connected with the analog-to-digital conversion part and is used for synthesizing the digital signal into a digital audio signal meeting the AES-3 standard. The converter can be used as an A/D converter for converting a received audio analog signal into a digital signal, and can also be used as a D/A converter for converting a digital audio signal into an analog signal for connecting a monitoring loudspeaker and a cinema audio-visual disability system.

Description

technical field [0001] The invention relates to the field of audio equipment, in particular to a two-way audio signal converter. Background technique [0002] A converter refers to a device that converts one signal into another. The current audio signal converter can only realize one-way conversion of digital signals and analog signals, and has few functions, which cannot meet the actual use needs. Contents of the invention [0003] In order to solve the above technical problems, the technical solution provided by the present invention is: a two-way audio signal converter, including a casing, an analog-to-digital conversion part, a digital-to-analog conversion part and a clock part arranged in the casing, the analog-to-digital The digital conversion part includes an analog input part, an analog-to-digital conversion part, and a digital output part connected in sequence; the analog input part is used to input a level signal, and the analog-to-digital conversion part is elec...
