[Audio Network Information]
The music recording console is used for self-recording of festivals with music programs as the main content, including songs, songs, radio dramas and recordings of various live performances. The recording place can be a recording studio, a theater, a concert hall or other places. Recording and production at the same location can also be recorded and produced in several places. Although there is no essential difference between music recording and language recording, due to the above characteristics, especially the staged orbital recording process popular in popular music in recent years, it has many characteristics of its own. Therefore, many new music recording consoles have been proposed. Claim. The following characteristics are summarized: First, many music programs have a large number of bands and more actors. In order to record all kinds of instruments and sounds, adjust their proportions and make sound quality. To handle, you must set up multiple pickup microphones. Therefore, the mixer is required to have dozens or even dozens of input channels. The track record also requires dozens to dozens of output channels to record each piece of music material onto the multitrack recorder. Second, each input channel requires a strong sound quality processing capability. The recording of pop music and popular songs requires a variety of sound effects through the mixer and external peripherals. Large-band music recording mixers require a full-band equalizer and high-low-pass filter for each channel. , pressure limiter, expander, delay reverberator features. Third, the modern staged track recording process determines that the recording time and location of various materials can be different, and the various states, parameters, and recording data (including track time allocation, etc.) of the mixer must be recorded and stored. Therefore, a computer-controlled mixer that can store various materials and memorize the state of the console comes into being. Fourth, in order to reduce the occupation time of the equipment, the mixer is required to have a high degree of automation, strong internal and external control capabilities, and can automatically switch to multiple states. Due to these requirements, the music recording console is developing in the direction of large (up to 60 input channels, more than 48 output channels), high sound quality processing capability, and high degree of automation.
The main functions of the music recording console are as follows:
(1) Multiple input channels, at least a dozen or more, have reached dozens of channels to meet the needs of multi-microphone pickup. It is possible to record the signals of various (group) instruments and individual parts on a multi-track tape, and perform sound quality processing and sound image distribution in post-production for fine carving.
(2) Multiple hybrid buses and multiple outputs. The signals of the input path during multi-channel recording are amplified and processed, and then sent out to the multitrack recorder for recording through the output channel. The distribution and downmixing of the signals at the time of program production are performed by the hybrid bus. Therefore, there are more than a dozen outputs for large-scale music recording consoles , and some have reached more than 48 channels. There are also dozens of mixed busbars.
(3) Each input/output path has a variety of adjustment functions. These include: 1 level adjustment function. In order to adapt to different sensitivity of the microphone and line input, the channel population has several different options, which can be adjusted within the range of 40-60dB. An overload warning indication is provided to prevent overload. The auxiliary output path also has a corresponding gain control. 2 In order to prevent the signal from being inverted, an inverting switch is provided to change the signal phase by 180°. 3 high and low pass filters cut off low frequency noise and high frequency hum into tape recording. 4 has multiple frequency equalization, covering the entire frequency band. The broadband music signal can be compensated. The large mixer has four frequency equalizations. The center frequency of each segment can be continuously slid. The Q value can be changed in a wide range. The lifting and attenuation are indicated by the dial. 5 has a delayed reverberation effect and a companding function. The channel device of the table can be used for sound quality processing or to produce some special acoustic effects. The filters, equalizers, delay reverberators, and companders of each path are componentized and can be cut/out with a button. 6 multi-distribution function of the input channel. This is an important feature of programming and downmixing. Each signal can be assigned to any path and line through the distribution matrix, or it can be assigned to the stereo main output path through the sound image potentiometer. 7 has channel silence function. In the tuning and synthesizing, the channel silence switch can be used to turn off any signal (or several channels) and stop sending it to judge the effect of the other channels.
(4) has multiple auxiliary outputs. Each channel's signal typically has several auxiliary outputs that are used to excite peripherals to achieve the desired effect, and the auxiliary output signals can also be used as various return signals.
(5) Multiple grouping functions of the input path. The grouping function of the path is often used in recording and production. The most important application is to interlock the paths that need to be grouped through the control voltage of the output VCA (voltage control amplifier) ​​of each path. For example, the input of 1-6 is the signal of the stringed instrument group. After adjusting the proportion of the 6 signals, it is programmed as a group to implement interlocking. When you want to fine tune the volume of a stringed instrument during recording (or production), the set can be adjusted simultaneously without breaking the balance. Mixers with dozens of input paths can often be grouped into groups, each of which includes several and can be controlled by another group or pathway.
(6) Flexible and diverse cut-in, cut-out and jumper functions. In addition to the frequency equalizer, filter, delay reverberator and compander component of each path, the direction and distribution of each path signal are very flexible. Through various switching buttons, it can be cut out from many positions of the path to any mixed bus and any auxiliary output bus. The mixer can't switch inside, and you can also send other lines through the exchange jumper.
(7) Two pairs of stereo output functions. The music recording console is a stereo output, so the main output is at least - for stereo output. However, considering the surround sound requirements of stereo programs and the need for 4-channel stereo, general music mixers have more than two pairs of stereo output channels.
(8) A variety of monitoring and monitoring functions. Monitoring during program recording is always the most important means of controlling quality. Monitoring in a large mixer has formed a separate system, in addition to listening to the main output channel signal, can also monitor each independent channel signal. It can be pre-listen (PFL) in front of the channel attenuator, or it can listen to the signal of a certain channel (SOLO), and can monitor the total effect after removing a certain signal. Large mixers can also monitor the auxiliary output signal and the returned effect signal. In short, signals that need to be controlled throughout the sound quality can be cut into the monitoring system for the sound engineer to listen to.
(9) Automatic mixing function. This is an important feature of the new music recording console . The mixer basically has two states in the recording work. One is that the original sound is picked up and recorded on the multi-track tape, which is the recording state. The other is to play back the material recorded on the tape. After being processed by the mixer and peripheral devices, it is downmixed into a stereo signal and recorded on the tape through a two-channel recorder. This is the mixing state. The position of the various buttons in these two states is different, and the signal flow direction is also different. To improve work efficiency, the mixer has designed an automatic mixing function that automatically connects each output unit to the main output path, switching from the recording state to the mixing state. The new computer-controlled mixing console can store the parameters of both states, and the state is automatically controlled by computer control, which is quick and convenient.
