Talking about the difference between the recorder and the recorder

When most companies meet, many people are accustomed to using the notes to record important things, not only because of its high quality and low price, but more importantly, the recorder is easy to use. Furthermore, you may not know the existence of Other recording devices! Today, I will tell you about the recorder. Although the recorder and the recorder have the function of recording, there are still some differences between them. Let me talk about the difference between the recorder and the recorder.

The main differences between the recorder and the recorder are as follows:

First, the power supply method

The recorder is powered by a lithium battery, and the DRM-101P live recorder is powered by AC to DC. Lithium battery power supply determines that the recorder is easy to carry around, which is probably the biggest feature of the recorder. This feature makes it very widely used. Sun Honglei also said that there is only a recording pen in the pocket, nothing to take out and record a few words. Tide. However, if you use it to record a meeting, it seems a bit chilly. Back to the topic, battery power is convenient, if the conference suddenly turns into the middle, there is no power, what should I do? It would be even worse if it didn't run out of electricity all the way. The DRM-101P live recorder is powered by 12V DC. If you have this condition, please connect it with a DC 12V lithium battery. We have tested it and can use it!

Second, storage capacity

This is simple to say, the recording pen is stored in the FLASH chip, and the capacity is dead. The SD card used in the DRM-101P live recorder is inexpensive and easy to purchase. It can support up to 32G. The larger the recording file of the same length of time, the better the sound quality. If a 2G recorder claims to have a clear and undistorted sound quality, it is basically blown. A 5 minute Mp3 capacity is about 5M, a 5 minute CD copy to the hard disk is about 50M, the two sound quality can be the same. The SD of the DRM-101P live recorder can be plugged and unplugged. If it is recorded, it can be directly removed and taken away. The recorder must be copied to the computer hard disk and copied to the USB flash drive. The program is cumbersome.

The DRM-101P live recorder also has an interface: Mic In, an external directional microphone that can capture a small range of sounds in noisy environments, and can be used in service counter recording, hotel front desk recording, cash register recording and other occasions. Using voice control or manual recording, no matter which way, it must be more professional than the recorder.

Third, the parameter settings

Many parameters of the recorder are fixed or simple. The DRM-101P live recorder can be set arbitrarily in terms of recording start mode and voice control delay. For example, if the voice delay is too short, it will cause a large number of small files to be generated. If it is too long, it will waste a certain amount of capacity.

Fourth, the gain adjustability

The recorder usually does not have this function. How much sensitivity is designed, and because the recorder is powered by 3V, this voltage cannot drive an amplifier, or the 3V voltage cannot make the amplifier achieve the best results. The DRM-101P has a gain adjustment knob that can be easily adjusted with a screwdriver. This adjustment is physical, by adjusting the resistance of the resistor for amplification purposes, unlike software amplification. Can be amplified without distortion and not broken.

Fifth, sensitivity

Sensitivity is the range that can be acquired. The higher the sensitivity, the larger the range of acquisition, and the smaller the opposite. First of all, the sensitivity of the recording device is high and low and it is a response to its advantages and disadvantages. Depending on the environment used, the sensitivity is not as high as possible. For example, in a very noisy environment, the sensitivity is too high, which will cause the recorded sound to be mixed with a lot of noise and can not be heard. If the sensitivity is too low in a quiet environment, the range of the acquisition will be too small, or the recorded sound will be too small. Of course, in the same environment, sensitivity is definitely a measure of the standard of a recording device.

Sixth, the interface

Ordinary recorders don't have any external jacks before, but most merchants are pursuing versatility and low cost. Although the line interface has been added in the later stage, it is almost all "image project". Most users can't use those interfaces, and they will not be able to do it well. It is also a waste. The DRM-101P conference recording device has its exclusive use. Since it is specially designed for conference room recording, it is natural. This interface makes its application range much larger. For large conference rooms or venues, direct access is not suitable. They are generally equipped with professional conference equipment such as mixing consoles, all with audio output interfaces. In this case, the DRM-101P conference recorder can take sound from the line. Enter its line input interface. Because it is the line to take the sound, the conference room is no big, and these sounds are sent through a professional microphone, the sound quality naturally did not have to say. I don't worry about the noise of the environment.

The sensitivity of the DRM-101P live conference recording device is much higher than that of an ordinary recording pen. Since it is called "on-site conference recording equipment", it determines its use environment, first, the environment is larger, and second, the environment is quieter. A 5, 6 meter long conference table with a voice recorder on it may be a little hard. The spokesperson sitting at both ends of the table must have been too small. The DRM-101P live conference recorder is more than enough. If the environment is good, the radius of 6 meters is not a problem, and the diameter is 12 meters. Generally small and medium-sized conference rooms are enough. While the DRM-101P live conference recorder is highly sensitive, it can also use its advanced chip to filter some noise to reduce noise.

In short, each has its own strengths and shortcomings, and the industry has specialized. For the occasion of catching up with the new wave, it is recommended to use a voice recorder, and the conference room is a meeting, naturally the recorder is better.
