The audio system refers to converting the sound wave signal of the original sound field sound with a microphone into a electrical signal, and the electrical signal is processed through some electronic devices according to certain requirements. FinallyThe entire composition from a speaker to a speaker is the audio system.
Sound system connection
Points of the device connection 1. Balance balance method: Now the sockets on the back panel of most audio devices are the balance port. We just choose to use the balance line of the XLR Caval connector to connect the device or use the TRS6.35cm stereo sound connectorThe balance line is connected to the device.2. UNBALANCE non -balanced square: Although the sockets on the back panel of most audio devices are now the balance port, some devices still have non -balanced ports. For example(Balanced output) and unbalanceout output, so we can also use the non -balanced line of the TS6.35cm mono connector to connect the device. As long as the line is not too long, the interference should not be too large, so that the connection is still possible.3. In input and output: Some beginners are dizzy when there are so many sockets behind the device. In fact, there is a trick: no matter what sound equipment, it can basically be divided into "in input" and "out output".Most of them, so we only need to recognize "in and out", and dont connect other unfamiliar sockets.
Audio system solution
The audio system design concept today and everyone tell the conference room hall as an example.First of all, we must consider the standards that a conference hall needs to meet.The first point must be advanced equipment, which can keep up with the development of the times, and not use old -fashioned equipment.The second is the advantages of the equipment. The equipment in the conference hall must be clear in quality, high sound quality, and good quality, so that it can be used for a long time, so that it can truly value it.Then, the audio system is safe and reliable, and the convenience of use will not be often bad.Finally, as a reasonable use of investment, if the equipment is scalable, it is foreseeable that the trend is not easy to eliminate.After considering the above factors, you can buy the audio system required for preparation.
Audio system brand
The KTV is relatively complicated, there are many brands, and the imports are BOSE, BMB, JBL. This is relatively high -level.Equipment, now engineer amplifier and speakers will be used in China, but the surrounding and predecessor still uses imported brands; the brand of domestic speakers is also full of dazzling HZ, Q cards, LAX, Beta3, etc.There are JBL, Madian, Lisu, EAW, and Meyer; like the mixer is basically acoustic, Yamaha, Meiqi, Allenheath, and low -end points are Park;Yamaha and Simi; the microphone is basically shure, Sennheiser, Iron Triangle; the effect of the effect of the effect of the effect of the Chinese market is TC, Yamaha, Lexicon; the crown, QSC, peak, and LAB recognized by the power amplifier.

Audio system composition
In simple terms, the sound source uses a carrier to record the sound on this carrier.In the broad sense, the sound source also includes playback equipment, such as CD machines, tape players, and so on.The power amplifier is the abbreviation of power amplifier. The role of power amplifier in the audio system is to magnify the weak electrical signal generated by the sound source, and then output to the speaker device to achieve sound output.A good amplifier is determined by the performance indicators such as power, distortion, signal -to -noise ratio, damping coefficient, impedance and other performance indicators.The speaker speaker is the most important part of the entire audio system.The role of the speaker is to restore the electrical signal transmitted by the amplifier into a sound signal and spread the spread.The quality of the speakers determines the first impression of the audio system. After all, the sounds heard by people are heard by the speakers.
