What Is a Curve Tracer?

With the popularization of digital music, more and more people play computer music. Enthusiasts who have burned out of the realm even set up their own audio studios, and some professional sound engineers have gradually turned to small audio studios due to cost budget constraints. The application of personal monitoring systems will become more and more widespread. In a monitoring system, the positioning tracker, as the last link, plays a vital role as the monitoring speaker, determines the monitoring quality of the entire system, and because the cost of the tracker is relatively low, the investment in the tracker is also The easiest to see the effect.

With the popularity of digital music, playing computer

Many sound engineers have long used a certain type of tracker and have developed their own listening habits. Generally, it is not easy to change the tracker model. Therefore, if you want to develop professionally in the future, it is recommended that you choose a high-quality and suitable monitoring system from the beginning. Not only is it good for making music, it is also great for establishing the correct concept of music balance and understanding of the sound. Help.

classification

The positioning tracker has a wide range of uses, including studio on-site return monitoring, studio mixing monitoring, sound reinforcement monitoring, broadcast monitoring, and special (special) monitoring.

Studio monitoring is divided into simultaneous (on-site return) monitoring and downmix monitoring. On-site return is generally to accompany music, beats or music melody to the recording singers and performers, just like singing karaoke music without original vocals. , The purpose is to let each singer, performer hear the rhythm and music, coordinate recording. Therefore, the requirements for this type of tracker are not high, but the prerequisite is that the tracker should be closed, because the condenser microphone for recording is very sensitive, and some faint details will be picked up, including the tracker. Leaking sound. For example, our most common AKGK271S, K141, SENNHEISERHD250, BEYERDYNAMICDT770PRO, SONYMDR-7506, etc., because a good tracker makes it easier for singers to invest.

Downmix monitoring has the highest requirements for the sound quality of trackers. It requires the ability to restore all sounds as realistically as possible, with as few sound stains and sound localization as possible. This is also the effect pursued by fever trackers, so this type of tracker Can be used as a fever tracker. Such as AKGK240DF, BEYERDYNAMICDT880PRO (now the model is DT880), SENNHEISERHD250, etc., of which the largest recording studio is AKGK240DF. However, conversely, fever trackers may not always be able to be used as positioning trackers, because most fever trackers have relatively severe sound effects, or the frequency response curve of the entire frequency band is not straight, or the phase characteristics are not good, although The hearing may be quite good, but for some bands or some instruments, the playback effect may be flawed. Of course, this is also related to the personal preferences of the sound engineer. Many sound recorders are used to a certain type of tracker and have developed their own listening habits. Generally, they will not easily change the tracker model they use.

The requirements for the tracker of the sound reinforcement monitoring can be high or low. As long as the positioning tracker of the ordinary ballroom can listen to the music and language content clearly, debug a satisfactory ratio of reverberation and human voice, and pre-monitor (PFL) Accurate, low-end trackers can meet the requirements. DISCO ballroom generally uses single or double ear closed positioning trackers, which require strong low frequency, high sound pressure, strong sound insulation, and durable, such as PIONEERDJ-1000, Panasonic and other models. For concerts and high-end sound reinforcement occasions, the positioning tracker has higher requirements, but the main monitor is usually a professional monitor speaker, and the tracker is generally used as an auxiliary monitor, using a high-end closed or semi-closed The tracker is enough, such as AKGK240M, K240DF, SENNHEISERHD250 and so on.

Broadcast monitoring is mainly required when the radio station broadcasts the program, the host and guests of the program, as well as the director, production director and other real-time monitoring. This broadcast requires the positioning tracker to have extremely high speech intelligibility and intelligibility, which can filter the noise that affects intelligibility and intelligibility in speech, such as low-frequency interference, telephone noise, etc. Of course, there will be special tracking The equalizer prepared by the router is operating, but the quality requirements of the tracker are still relatively high. At present, there are no more than AKG's K240M and K240DF, and there are also K100, SENNHEISERHD250, HD280PRO, because the sound of these trackers are relatively dry and the speech intelligibility is relatively high.

The last is dedicated monitoring. This kind of monitoring abounds around us, such as the paging lady of the paging station, the operator of the telecommunications bureau, etc. They all wear closed positioning trackers with microphones, and they also require high language intelligibility. There are also pilot monitoring on the aircraft, dispatch monitoring on racing drivers, command coordination monitoring on tank occupants, and sonar monitoring on submarines, all of which use different special trackers according to different needs.

Features

Durability

Fever trackers are aimed at enthusiasts, and are usually stored in a home environment, which is more delicate. Generally, the production materials use ABS engineering plastics, the structure is more complex, and they are relatively not strong. People who use professional positioning trackers to "work" use it. I am afraid it will not be too cherished, and the frequency of use is very high, and the environment of use will be more complicated, so it is required to have a simple structure, durable and durable. In addition, the earmuffs of positioning trackers are usually made of leather and are not easily soiled.

Wear securely

There is another difference between a professional positioning tracker and a fever tracker, because when a recording engineer works with the positioning tracker, he will not roam around like an enthusiast enjoys music, but is very busy, and people are constantly on the move. Motion, it puts forward a requirement for the tracker, which should be worn more firmly and tighter, and cannot be easily slipped off. In addition, tighter wearing trackers also provide better sound insulation and meet the needs of a recording studio. Therefore, the positioning tracker has a parameter called average pressure on the ear (average ear pressure), which is the pressure value of the tracker unit on the auricle. The ear pressure of professional positioning trackers is generally greater than the fever tracker.

Spring wire

Many connecting cables of positioning trackers are spring wires such as telephone lines. The purpose of this design is to control the length of the wire. It is not easy to be tripped by many knobs on professional equipment such as mixers. At the same time, its good elasticity is also good. Avoid damage to the wire due to pulling.

Other features

Some positioning trackers are very delicious in design, such as AKGK271S, you will find that it will sound when you wear it on your head, and it will not sound when you remove it. Take a closer look. The original tracker was designed with a micro-switch. The tracker unit was turned on with it, and it was disconnected after being taken off. This design will extend the life of the tracker unit, and it will be very quiet. In the recording studio, the automatic shutdown function can keep the quiet state in the recording studio, and will not affect the work of equipment such as microphones.

In summary,

With the improvement of living standards, wireless communication technology and global satellite positioning system (GPS) technology are increasingly used in all aspects of daily life. Whether in security monitoring and maintenance, wireless communication (GSM) and DGPS technologies play an important role. A GSM-based wireless communication network covering a large range of data has been destroyed, easy to use, and low cost. Separate GPS system, GSM system, vehicle and personnel mobile phone users through wireless satellite positioning communication link to complete vehicle and personnel monitoring and send location information.
