Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0030] A tuning system for a knob-type mixer, comprising:

[0031] Such as figure 1 As shown, the tuning knobs are: the left channel knob HI (used to adjust the EQ of the high frequency band, the other knobs are similar), the left channel knob MID, the left channel knob LOW, the left channel knob FILTER, the right channel knob Knob HI, right channel knob MID, right channel knob LOW and right channel knob FILTER.

[0032] Such as figure 2 As shown, with a midpoint potentiometer group, which includes: left channel potentiometer HI, left channel potentiometer MID, left channel potential LOW, left channel potentiometer FILTER, right channel potentiometer HI, right channel potentiometer MID, right Channel potential LOW, right channel potentiometer FILTER. The left channel knob HI corresponds to the left channel potentiometer HI, the left channel knob...

Abstract

The invention provides a tuning system and method for a knob type sound console. Eight tuning knobs correspond to eight potentiometers one by one; an analog output terminal of each potentiometer is connected to an electronic switch; and an analog output terminal of the electronic switch is connected to an IO pin with a built-in ADC function in an MCU. The MCU is provided with three common IO pinsconnected to an address decoding input terminal of the electronic switch. The MCU detects level states of the eight paths of potentiometers in real time; according to a function relationship between parameters like a frequency and an amplitude of an EQ filter frequency response curve in a DSP and sampling values, the MCU carries out software calculation based on the location of a knob cap markingpoint indirectly to obtain an EQ parameter corresponding to the location of the point; and then the parameter is written into the DSP by an SPI bus to improve the tuning effect.

Description

technical field [0001] The invention relates to the audio field, in particular to a tuning system and method for a knob-type mixer. Background technique [0002] The mixer is a special tool used by the tuner for tuning. In order to increase the tuning function, multiple knobs or buttons are generally integrated on the mixer. This knob or button is responsible for independent functions. Cooperate to achieve tuning. As far as the current situation is concerned, the more function knobs integrated on the mixer, the richer the tuning effect will be. However, this mixer has a complicated structure and is expensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tuning system and method for a knob-type mixer, which has a simple structure and can realize different tuning effects. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a kind of tuning s...
