- Sound quality is an important criterion for determining the quality of audio equipment, including indicators such as signal-to-noise ratio, number of sampling bits, sampling frequency, total harmonic distortion, etc. The level of these parameters determines the sound quality of the audio equipment.
Audio equipment device type
- Device type refers to the type of audio equipment, which is the type of audio equipment that belongs to amplifiers, speakers, multimedia consoles, digital mixers, audio sampling cards, synthesizers, mid- and high-frequency speakers, microphones, PC sound cards, and headphones. device. Here are a few of the more common audio devices.
Audio equipment amplifier
- Amplifier is the most basic equipment in the audio system. Its task is to amplify the weak electrical signal from the signal source (or the mixer in the professional audio system) to drive the speaker to produce sound.
- The mixing console is also called the mixing console. It amplifies, mixes, distributes, modifies the sound quality, and processes the sound effects of multiple input signals.
- The mixer can be divided into analog mixers and digital mixers according to the way the signals come out.
Audio equipment audio workstation
- The audio workstation is an integrated professional audio workstation that integrates audio recording, audio editing, internal effects processing, automatic downmixing and other functions. It is composed of a computer and its operating system, audio card and functional software. The audio card is the most core technology, and the functional software is developed on the basis of the special development kit provided by the audio card.
Audio equipment synthesizer
- Synthesizers are all kinds of box-type devices connected to each other, and finally connected to a keyboard. When you press a keyboard, a unit containing a vibrator will make a sound, and some box devices, a filter, will control the sound of this sound. An amplifier controls the volume and so on.
Troubleshooting audio equipment and solutions
- The sound card status is normal, but all audio programs show no audio device symptoms: The sound card driver status in the system is normal, but all audio-related programs show no audio device [1] .
- Reason: Unknown, most commonly found in abnormally installed operating systems, such as: depth, tomato garden, rain forest, etc. confirm:
- 1. Right-click on the "My Computer" icon and select "Manage" from the menu to open "Computer Management" [1] ;
- 2. Select "Device Manager" in "System Tools" and turn on "Sound, Video and Game Controllers" [1] ;
- 3. Right click on the sound card model and select "Properties" [1] ;
- 1) "General" "Device status" shows: "This device is operating normally. If there is a problem with this device, click" Troubleshoot "to start troubleshooting." 2) "Driver", "Driver Provider" "Driver Date" and "Driver Version" are normal) Select "Multimedia Device"-> "Audio Device" in "Properties", there is a sound card model below, click "Properties" [1]
- The status shown here is: The driver is enabled but not yet in use. Note: The above conditions must be met, otherwise the problem cannot be solved by the following methods. Solution:
- 1. Click "Start Menu"-> "Run", enter: inf, press Enter, you can open the driver installation information directory of the current system [1] ;
- 2. Find the following machine.inf and copy it to another location, for example: Desktop [1] ;
- 3. Use Notepad to open machine.inf and find ExcludeFromSelect = *. Delete this line and save it [1] ;
- 4. Open "Start Menu"-> "Settings"-> "Control Panel"-> "Add Hardware" in turn, and after the search is complete, select: "Yes, I have connected this hardware (Y)",-> "Add New Hardware Device "(located in the last item of the" Installed Hardware "list) > Install the hardware selected in the manual cluster list (advanced) (M) > Show all devices > From Disk Installation " [1] ;
- 5. "Manufacturer file copy source (C)" Here, select the previously modified machine.inf, and find "PlugandPlaySoftwareDeviceEnumerator" whose manufacturer is "standard system equipment"; Note: The left column does not need to be changed when selecting, select this from the right column device
- 6. Click "Next" to complete the installation, and then reinstall the sound card driver to use it normally [1] .
