Digital mixer function analysis

This journal takes the famous Mickey D8B as an example to show you all the representative functions of digital mixers, as a "brick" for peers to discuss digital mixers in depth.

Press: Digital mixer as a new force of audio equipment has occupied an important seat in the field of professional recording, especially in the past one or two years, digital mixers have begun to get involved in sound reinforcement venues. It is obvious that the transfer of mixers from analog to digital is generally not possible Ignore the trend. However, due to the many interfaces of the digital mixing console and the poor intuitive operation, many users have a sense of respect.

If you take the common analog mixer as a measure, the Mickey D8B digital mixer is completely beyond the scope of the mixer. In addition to having enough functions to achieve a large analog mixer, its complete digital recording interface and the amount of support The software of the three-party effect processing plug-in, surround sound processing, functions comparable to audio workstations, etc. all remind us that when learning a digital mixing console, you must first improve your "consciousness", especially those who are engaged in sound reinforcement. Don't be surprised by the function of the digital mixer.

The D8B digital mixer is characterized by its powerful operating software and intuitive display interface. You can directly operate the digital mixer without an external monitor, so you can use it for faster operation. You can see 24 channels at the same time (including V-POT multi-purpose adjustment knob). The corresponding functions on the 4 centralized control pages can be controlled by buttons on the screen.

Each channel on the screen includes: insert distribution display before digital sound field processing (DSP) and pop-up window display1. Left and right channel distribution bus indicator 2; direct distribution input and output, recording level adjustment of the recording base, digital sensitivity adjustment 3; compression / threshold / equalization / phase polarity switch 4; equalization curve display 5; digital sound field processing DSP inserts the distribution display And pop-up window display 6; auxiliary sending instruction 7; selected channel display 8; recording / writing status display 9; V-POT multi-purpose data setting button, by default, channel audio and video control 10; selection / solo selection / Mute key 11; Channel description 12; Fader status display 13.

Fat Channel

Multi-purpose setting area

All channel effects, pass selection, auxiliary sending, and digital sensitivity setting status are displayed in a very intuitive way. Just double-click the channel selection button when you need to adjust it, and you can hide it when you do nâ€™t need it.

Equalization: adjust the 12 screen knobs, at the same time you can see the actual adjusted effect parameters from the 12 data windows on the right-or by dragging the data to change its parameter configuration, you can even use the mouse to drag the effect or the balance curve intuitively To change the effect settings.

You can choose four-band equalization (briTIshEQ): they are low-band / high-pass filtering, two-band IF parametric equalization, and high-band / low-pass filtering; H / P equalization is also available: it has 1 low-band / high-pass Filter equalization and three high-end parametric equalization bands, a total of four parameter adjustment bands, the center frequency of each band can be scanned in the range of 20-20KHZ, and each EQ parameter and type can be saved and stored in the program It can be recalled and used at any time during operation, and can also be copied and used in another channel.

You can set two EQ parameter memory locations, and you can quickly compare A / B effects. You can also establish a fade transition time between the two parameters, which will smoothly transition from the EQ memory state A to the memory state B within the time period you set.

V-POTTM functional area

The V-POT selection operation area is on the right side of the main screen and is used to assign adjustment and operation functions to each independent channel. Carry out the corresponding V-POT operation. Similar to the previous channel display, it also includes insertion 1 of the left / right and main L / R bus; main fader selection and "write" function key 2; V-POT tracking and digital sensitivity indication 3; auxiliary distribution 4; monitor power Ping and monitor panning distribution allows you to create two different monitor mixes 5; main panning and solo selective listening and front and rear panning status 6; main panning control and status display 7; central control page selection 8; main fader 9.

Compression and threshold

Channel selection 1 allows you to quickly select a channel among all channels, assign a channel to a bus or switch the signal phase, you can also assign a channel to output directly by clicking the button in the green ROUTE TO TAPE selection area, version 3.0 operation The system supports insertion options before or after DSP, and includes an independent EQ adjustment function, which can be dynamically adjusted through the EQ control of the fat channel. It assists sending and digital sensitivity adjustment area 2; more details of V-POT function settings.

Remix editor

The mixing editor is an interactive display interface that provides almost all the adjustment options available on a channel, including channel fader (FADER) level and mute. L / R and front main channel / rear surround sound image, digital sensitivity, auxiliary and monitor level, monitor image, bus and L / R distribution, phase reversal. "SOFT-KNEE" compression and "KEY" input attenuation level / EQ gain / EQ frequency / EQ bandwidth. In fact, everything is displayed in a graphical interface.

Surround sound

The surround sound window allows you to intuitively control the position of the sound image in multi-channel downmix mode, and there are multiple modes to choose from: such as QUAD, LCRS mode, 5.1 and 7.1 channel modes. The display interface shows an intuitive and visual "hybrid platform" of a multi-speaker surround sound system. A luminous point shows the position of the channel track sound image in the sound field space. You can smoothly fade (change) a channel position variable within a period of time. Version 3.0 surround sound processing enhancements include: sound image, central sound field sound image depth, surround sound LFE (low frequency effect) gain control for each channel, surround sound bus and track distribution, and a 72-channel surround sound state display. Needless to say, all of the above functions can be performed fully automatically.
Local remote control:

This floating window is your "virtual remote control", which can be used to remotely control external digital recording devices, such as HDR24 / 96, or other devices that support MIDI transmission control protocol (including MIDI sequencer and DAW digital audio workstation) , It includes a time code display bar, a track list with a slider, and some operation function keys such as: pan, mute and finger touch automatic mode.
