Will the DSLR mixer greatly improve the sound quality?!

SLR to the mixer and then to the microphone, it is indeed stronger than directly connected to the microphone, the mixer is recommended to use those designed for the SLR, for example, I have used two mixers from Beachtek, because the recording of the SLR has the function of AGC automatic gain, when the external sound becomes smaller, it will automatically increase the recording level to compensate, the most intuitive listening sense is that the sound becomes louder as soon as the sound is small and low noise. BeachTek's console has a function that can always emit a high-frequency sound that is inaudible to the human ear but can be recognized by the SLR, so that the SLR mistakenly thinks that the sound is always loud, and it will not gain automatically. This kind of sound is only available in the right channel, so the left channel just copied the right channel.

Put the footage in the PR, the recording meter shows that the level value is always high, but you can't hear that high-frequency sound, you can also use the low-pass filter to cut out the high-frequency, but it doesn't have much effect. We used this method to shoot a lot of character interviews for column dramas and feature films, and the effect was acceptable (better than not using a mixing console). Another advantage of using a mixer is that you can use a better microphone, which generally requires external phantom power.

The DSLR itself has a very low voltage and cannot effectively drive such microphones. But in general, the recording effect of SLR is indeed not as good as that of traditional professional cameras, and the intuitive auditory reflection is that the low noise is large, and the sound level is thin.

The low noise may be slightly louder when the DSLR is connected to the mixer, but it does not have a particularly large impact on improving the sound quality.

The mixer, also known as the tuning console, will amplify, mix, distribute, modify the sound quality and process the sound effects of multiple input signals, and is an important equipment for broadcasting and recording programs in modern radio broadcasting, stage amplification, audio program production and other systems.

Mixers can be divided into analog mixers and digital mixers according to the way the signal comes out.

No, the more things you have in the system, the more interference there is, and a good mixer is a little less distracting, but not none.

No, good things can only be restored a little better! Bad mixers have worse sound quality.

Not necessarily, the mixer is actually a multi-purpose professional preamplifier, the main function is to be able to synchronously amplify the output of various signal sources, and at the same time modify the timbre of various signals, but due to the relationship between use and cost, it still cannot reach the level of home HIFI preamplifier, except for high-end recording studio special mixers.

It's not that the bigger the mixer, the better the sound quality, the sound quality has something to do with many things, such as whether your ** is lossless sound, whether the cable is not aging, whether the interface is loose, audio quality, etc. The larger the mixer, the more channels the more functions may be, and the larger the mixer is generally used in large recording studios, halls, etc., because there are more recording equipment and more tracks occupied, which has nothing to do with sound quality. Of course, if you buy a miscellaneous mixer, the sound quality may also be affected by the workmanship of the circuit.

The main function of the mixer is the distribution center of the audio signal, and there is no need to use the mixer if there are not too many devices linked or functions that require various signals (such as split-track recording, wet recording, drying, etc.). The mixer can control the volume of multiple signals separately, perform preliminary EQ adjustments, etc., and it is used to collect multiple signals and unify them into the main output. Further functions such as high-end mixers have marshalling outputs, bypasses, buses, etc., which can separate the outputs in different places as signal distribution.

Use the mixer, when linking, look for the flow direction of the signal, **in**out it. In terms of tuning, according to the use of the mixer and the use of the scenario, the needs are also different, such as live sound reinforcement, if the sound is too muffled and too sharp, these can be initially adjusted with the EQ in the channel, and some mixers have more functions, such as compression reverberation and so on. If you end up mixing in the computer's audio workstation, if there is no problem with the sound quality of the general recording, we will not process the audio on the mixer, and try to ensure that the purest sound is recorded and then processed on the computer.

The mixer needs to be connected to the amplifier.

The mixer is just a device that processes the signal, and it is difficult to hear without an amplifier.

The function of the mixer is mainly used for mixing, controlling the volume of various sound sources, adjusting the sound quality and phase, so that the output of various sounds is consistent, and the three-dimensional effect is obvious.

The function of the amplifier is to amplify the signal and drive the speaker's pronunciation.

Hello 1, the role of the mixer is mainly used to mix, control the volume of various sound sources, adjust the sound quality, phase, so as to make the output size of various sounds consistent, three-dimensional sense is obvious, for example, a symphony band so many instruments, the sound of various instruments is large and small, there is no mixer, the small sound of the instrument will be capped by the big sound, with effects can also delay the signal, reverberation and other processing. Another aspect is to provide a variety of auxiliary interfaces, easy access to some external equipment, such as exciters, phase shifters, fill amplifiers, tape recorders, monitors, etc.

2. The function of the power amplifier is to amplify the signal and promote the sound of the speaker.

3. The mixer can input signals to the computer, depending on what output interface your mixer is, generally a single-core plug or card faucet output, and there are also lotus heads. When connecting, if not, you have to convert them into lotus heads, and the adapters are sold online.

Then use a cable to turn a double-headed lotus flower to connect to the line input of the computer's sound card (blue interface).

4. If the computer motherboard has its own sound card, there is no need to connect an external sound card.

Of course. The mixer is just a device that processes signals, how can you listen to it without installing amplifiers and speakers? Is it possible to listen directly to the mixer with headphones?

The signal from the mixer and the effect is so small Are you sure you can hear it 8-way mixer is not a waste If you are connected to the computer, you can use the total output left and right or over there Even the computer must remember not to plug in the wrong port There is a symbol in the mouth The blue one (remember that there is an arrow symbol inward) is tuned to linear input in the sound card controller Finally, remember that the level of the mixer is a little higher or smaller, otherwise your sound card will have to be careful.

There are now two kinds of mixers, one is the one with its own amplifier, and the other is the traditional mixer! Let's take the traditional one (the built-in amplifier is an artifact, you know), if you want to connect the mixer to the stereo, you must use the amplifier! You can connect to the computer or the sound card, as long as it is for audio production, you don't need to connect the power amplifier (at most, you need to connect the monitors).

You don't need a sound card to connect to the computer, so you can say that a good mixer is a good sound card or even good!

If it's professional audio, I think a mixer can replace an amplifier.

There is no wiring skills, there is nothing to be lazy in the professional system, everything in addition to the system according to the needs of the site, but also according to the different equipment to complete the line connection.

The mixer itself is not complicated, and it can be divided into these parts:

1. Input part;

Second, the regulation control part;

3. Output control and marshalling part;

4. Auxiliary input and output part. It depends on what kind of mixer you have, generally such as performance mixer, recording mixer, matrix mixer, etc.

Commonly used peripherals such as equalizers; effects; digital audio processors; crossovers; feedback suppressors; Voltage limiter; exciters; signal splitters, etc. Of course, these are generally not used so completely, depending on the place of use, here is only the audio processing equipment of the mixer.

Preamp source equipment such as microphones; DJs; ***；computers, etc.; Commonly used equipment for musical instruments such as; Keyboard; Guitar; Bass; drum kits; piano, etc.

Let's talk about the audio source input part first, the first few channels of the mixer are generally used as microphone input, and the balance connection must be made, that is, the XLR connector, and the other audio sources are followed by the input, and then the instrument part, the general mixer has stereo input, which can be used to input stereo sound such as keyboards.

As long as the number of channels on the platform is enough, the gain of each input should be adjusted first, and then EQ adjustment should be made according to its sound characteristics, such as the drum kit, which is the instrument with the most inputs.

The input part is completed here, and then the output of the mixer, many platforms have marshalling output, and the distribution is also more flexible, for example, the main output is the main speaker signal output on the spot, the group one or two is used for stage monitoring, and the third or fourth is used for subwoofers.

Of course, it is also possible to use the auxiliary output of the station, such as the audio control or the DJ's monitors, all connected on the basis of convenient control and electroacoustic theory.

If you all know the role of the above peripherals and the connection of their input and output, then these are not difficult things for you, that is, the order problem.

As the process center of the sound signal, the mixer is the core of the professional electroacoustic system, with the preamplifier as the main body, receiving multiple channels of various audio source signals with different impedances and different levels, and processing the signal for equalization, effect, mixing, distribution, grouping, and panning adjustment, so as to ensure the best signal-to-noise ratio, high-quality, and high-efficiency transmission of sound signals.

Mixer tips.

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.

How to tune the mixer to sound the best:

1.Sound quality compensation.

The sound quality compensation of the mixer is to be processed in conjunction with the sound source, not only technically but also artistically, but also in conjunction with the auditory psychology of the listener. Sound quality compensation is to use the sound quality compensator to adjust the center frequency of each frequency band to change the timbre of the sound.

2.Volume adjustment.

The purpose of volume adjustment is twofold: one is to control the dynamic range of the sound signal, and the other is to adjust the proportional relationship between the signals. Volume adjustment needs to be done in conjunction with sound quality compensation, because volume and frequency are inseparable.

Therefore, before tuning, the dynamic level, frequency characteristics and the proportional relationship between the various signals on the scene should be well understood, and it is necessary to listen to it many times and debug it repeatedly, and at the same time, it is necessary to take into account the various conditions and playback effects of future playback.

3.Volume adjustment and sound quality compensation.

When the volume is small, pay attention to increasing the low and high frequencies; When the volume is high, the midrange is appropriately increased to enhance the brightness of the sound.

Tuning is dominated by singing. Before the singing, the accompaniment is gradually lowered to accentuate the singing. The low frequency should be attenuated by 3 dB 5dB, the high frequency above 7kHz should be attenuated by 3dB, the middle and low frequencies can be increased by increasing the intensity near 200Hz, and the 2kHz 4kHz should be increased by 3dB 6dB.

For disco or rock music, pay attention to the low frequency (40 Hz 100Hz) and high frequency (7kHz 20kHz) to increase the high frequency significantly.

Do not turn the compensation knob violently when boosting the bass, so as not to damage the amplifier and speakers due to excessive power output. The same is true for the low-frequency adjustment of the equalizer.
