Functions of four common output modes on the mixer:

1. Amplification of program signals

When signals from different program sources enter the mixer, different signals need different amplification amounts, so the mixer must be able to handle different signals separately. For example, the musical signals and vocal signals of various musical instruments are different in amplitude, so it is necessary to process them separately.

2. Adjust the frequency of various signals separately (i.e. tune)

We know that different signals have different timbres due to their spectrum distribution, harmonic components and other reasons, and the influence of buildings on the sound has greatly changed the timbres.

the sound engineer should process the different sound signals entering the mixer according to different amplification environments, so as to make the sound as close as possible to the original sound. Each channel of the mixer has the same processing means, such as 3-segment equalization, gain controller, high-pass filter, etc.

3. Combination of signals

After adjusting various signals, the mixer should combine various signals into standard left and right channels (stereo) and output them as input signals for the next level equipment, which is the most basic function.

4. Distribution function

In addition to the main output of stereo, the mixer can also provide more than two auxiliary output signals, which can be used for two purposes: one is sound room monitoring or stage listening; The second is to be used as the excitation signal of the effector.

Extended information

Matrix mixer belongs to music mixer. Musicians can create different styles of music through this matrix output. The difference between it and the general mixer is that a matrix bus is added, and all kinds of acoustic signals can be separately programmed into the matrix bus. The acoustic signals sent from the matrix bus are mixed and amplified, divided into multiple groups, and the size of each group of signals can be adjusted, and then mixed. The mixed signals are adjusted in size through matrix output, isolated and amplified, and finally the matrix acoustic signals are sent.

each input channel is provided with a button to enter the matrix bus after its fader, and different types of music signals are intercepted on the matrix bus, for example, a drum signal is input to an input channel, the drum sound is loaded on the matrix bus 1, and the M1 button on this channel is pressed. An input channel inputs a flute sound signal, loads the flute sound on the matrix bus 2, and presses the M2 key on this channel.

an input channel inputs a trumpet sound signal, loads violin sound on matrix bus 3, and presses M3 key on this channel. An input channel inputs a trumpet sound signal, loads the trumpet sound on the matrix bus 4, and presses the M4 key on this channel. In this way, by adjusting the adjustment buttons of 16 squares before the matrix output, playing music with different tones as the main body can be generated at the matrix output end.
