How to maintain the mixer, how to use the mixer

Mixer daily maintenance and maintenance recommendations:

1.The normal operating temperature of the audio equipment should be between 18 and 45. Temperatures that are too low can reduce the sensitivity of some machines, such as tube machines; If it is too high, it is easy to burn out the components, or make the components age prematurely. In summer, special attention should be paid to cooling down and maintaining air circulation.

2.Keep audio equipment out of direct sunlight and avoid being near heat sources, such as heaters.

3.After the audio equipment is used up, each function key should be reset. If the function key is not reset for a long time, the pull button spring is in a state of stress for a long time, which is easy to cause dysfunction.

4.Before switching on and off the audio power supply, turn the volume potentiometer of the power amplifier to the smallest level, which is an effective means of protection for the power amplifier and speakers. At this time, the power amplification of the power amplifier is almost zero, at least it will not cause harm to the speaker in case of misoperation.

5.When turning on the power on, from the front to the back, that is, the CD player is turned on first, and then the front and back amps are turned on, and the volume potentiometer of the power amplifier is turned on to * small. Turn off the amplifier when shutting down, so that the amplification function of the amplifier is completely turned off, and then when you turn off the front-end equipment, no matter how large the impulse current is, it will not affect the amplifier and speakers.

When the surface is also closed, the volume potentiometer of the amplifier should be turned to * small, and the CD player can be turned off or turned off after release.

6.Machines should be commonly used. It is commonly used to prolong the life of the machine, such as some parts with motors (recording base, laser record player, laser disc player, etc.). If it does not rotate for a long time, some parts will be deformed.

7.Electricity should be applied regularly. In the case of long-term non-use, especially in humid and hot seasons, *power on for half an hour every day. In this way, the heat generated by the working components of the machine can be used to drive away moisture and avoid moisture and mildew in the internal coils, speaker voice coils, transformers, etc.

8.Wipe the surface of the machine with a clean, damp soft cotton cloth every once in a while; When not in use, cover the machine with a dust cover or cover cloth to prevent dust from entering.

9.From the principle of electronics, any electronic equipment should not be connected or disconnected from other devices in a live working state, which I think friends can understand without too much explanation, it is very dangerous to plug active devices with electricity, and even passive devices such as microphones do not advocate live plugging. It should be reminded that you must not open the amplifier to connect the speaker wire, because the binding post of the speaker is generally very close, and the speaker wire is two tightly parallel, and the speaker wire is often accidentally short-circuited when wiring, and the consequence will be to quickly burn the amplifier.

Although some amplifiers are equipped with protection circuits, some Hi-Fi class pure amplifiers often omit this part of the protection measures in order to improve sound quality and reduce unnecessary sound coloration. Therefore"Turn off the machine and rewire"is a rule that must be followed.

10.Some particular friends will not button the loud volume and put some explosive ** when the amplifier is warmed up, the reason is that the power amplifier components are in a cold state when they are just turned on, and then let them work at a high current will shorten their life. Therefore, it is recommended to only put some soft**and listen at medium volume** within half an hour of just starting the machine, and then turn on the loud volume to enjoy it after the machine warms up.

This is more professional, it is recommended to contact the manufacturer. But on the whole, electrical equipment is afraid of moisture and dust.

I guess you still have to clean the inside part, it is recommended that you use anhydrous alcohol in the gap of the slide resistor to push and drip in, pay attention to be 100 anhydrous alcohol

After cleaning, just use a special electrical appliance Vaseline to spray lubrication

Pay attention to the authenticity of all kinds of canned spray cleaners on the market outside

1.Sound quality compensation.

Sound quality compensation is to use the sound quality compensator to adjust the center frequency of each frequency band, so as to change the timbre of the sound.

2.Volume adjustment.

Before tuning, it is necessary to understand the dynamic level and frequency characteristics of the acoustic signal and the proportional relationship between the live signals. It is necessary to audition and debug many times, and at the same time, it is necessary to take into account the various situations and effects of the future **.

3 signal inputs.

From top to bottom is the tweeter XLR socket, the receiver input, which usually provides conversion power.

4. Plug into the socket.

The insertion point is usually located in the input channel of the mixer, which is in front of the signal path, and sometimes directly in the input channel. This dynamic processor insertion point is typically used.

5 sound control panel.

There is a four-segment control board, where we can adjust the high, medium, and low signal frequencies for each channel.

6 Signal Tuning Meter.

Use the aux send port to send the signal to an external processor for effects processing, and then send the processed signal to the tuning table through the aux return port. When assigning outputs, the bus can be occupied by the main output, sub transmission, and return, and with only four signal outputs, the more lines can be assigned, which is important for multichannel recordings.

When raising the bass, do not jerk the compensation button to avoid excessive power output damaging the amplifier and speakers. Low-frequency adjustment of the equalizer is also required.

Summary. Hello dear, a mixer is an audio device that is used to mix and process multiple audio signals. Here's how to use the mixer basically:

1.Connect audio devices: Plug audio devices (such as microphones, musical instruments, speakers, etc.) into the input channel of the mixer.

2.Adjust the volume: Adjust the volume by turning the knob on the channel.

The volume can be checked through headphones or speakers. 3.Adjust the tone:

Mixers usually have EQ (equalizer) controls that adjust the bass, midrange, and treble of the audio signal. 4.Add effects:

Mixers usually have built-in effects like reverb, delay, chorus, etc. The intensity and parameters of the effect can be adjusted by knobs. 5.

Mix audio signals: Mix multiple audio signals together, and the volume and balance of each channel can be adjusted with a rotary knob. 6.

Output Audio Signal: Outputs the mixed audio signal to a speaker or recording device. It is important to note that different mixers have different functions and controls, so you should read the user manual carefully before using it.

How to use this.

Haven't touched this thing, no.

The operation was as fierce as a tiger, and the result was still a countdown.

1. Pre-tuning of input and output signals, in the actual tuning process, the audio system should first be pre-tuned according to the actual situation of the scene. At the same time, the input signal and output signal of the sound source should be simulated and debugged. The input signal is controlled by the input sensitivity (gain) knob, when the input signal is too large, the peak indicator (peak) will flash to tell you to turn the input signal down, otherwise it will be distorted.

The output signal is controlled by a linear push-pull low-noise potentiometer fader fader to control the level of the signal sent to the left and right channels of the stereo main output and the group output bus, and the fader controls the output volume of the channel. At the same time, it is used to adjust the balance of the volume between the input signals and the sound sources. Do not make the input signal of one channel too large and mask the signal of other channels.

2. To adjust the channel gain of the mixer, to input the audio source into the mixer, the author must first distinguish whether it is low impedance or high impedance, and then use a standard signal line to correctly connect to the mixer. If you want to achieve perfect sound quality for every sound source, you need to adjust it carefully. The gain of each input channel of the mixer is very important and crucial, but many sound engineers seem to think of gain as simply a volume knob, which is very wrong.

In fact, the gain is mainly used to control the dynamic range of the input signal, and generally when the gain is adjusted to the maximum without distortion, it is the maximum effective dynamic range, and it is also the best effect state. It's hard to understand this, but let's describe it with water: the input channel and input line of the mixer will have a basic noise floor, which is like the mud and sand in the bottom of the river, which cannot be eliminated.

As you know, when the river is not deep, the flowing water is under the sediment, and the water quality is definitely not good.

3. When the gain is adjusted, the equalization group of the mixer channel should be adjusted, and the order of adjustment should be from the bass part first, and then the middle and high pitch parts should be adjusted. Because only the basic tone of the sound can ensure that the sound is good multiple overtones. Basic tweaks are fine.
