In the work of public broadcasting, many equipment manuals are in English. If you don't even understand some basic industry professional English, you will encounter many difficulties in your engineering assignments! Below is a collection of industry-specific professional English to help you easily overcome difficulties!

Mic.=Microphone microphone jack (commonly known as microphone or microphone)
Mix Mix
 
frequency response
The relationship between microphone output and frequency refers to the change in output voltage measured by the microphone at different frequencies under a fixed sound pressure in a frame.
directivity
The directivity of a microphone refers to the ratio of its sensitivity in a certain direction (2 angles) to its greater sensitivity (O degrees) at a specified frequency.
CD
CD is the abbreviation for Compact disc, which usually refers to a small digital sound recording system that uses laser methods to pick up sound signals
CD-ROM disc
It is the process of recording computer software in a specific format onto a CD.
CD-V disc
It is a CD that records music and some still pictures, also known as a graphic CD.
CD-V disc
In addition to recording the same audio signal as a CD, there is also a 5MIN image signal.
CD-I CD
It is an interactive or CD disc, also known as a conversational CD disc. The information recorded on the disc can be communicated with the user.
CD-R optical disc
It is a one-time recording disc, also known as an additional recording disc, provided to users as a blank disc. Users can use CDs to record audio, video, or graphic information, and once recorded, it cannot be erased as a permanent record.
MD CD
It is a type of magneto-optical disc that can be used for repeated recording and playback. The straight-line diameter is 64mm. During recording, a magnetic field is applied above and a laser beam is applied below. There are information reading windows on both sides.
MPEG
Digital audio and image compression encoding technology.
Peak Music Output Power (PMPO)
Refers to the higher music power that an amplifier can output when the volume and tone of the amplifier are adjusted to a higher level without calculating distortion.
reverberation time
An important parameter for measuring the sound quality of Wanzhong is its length, which has a significant impact on the listening experience in the hall. Its definition is to stop producing sound after reaching a steady-state sound field. The sound attenuation is 60dB. The time elapsed is denoted as (60) in seconds.
Greater pressure level
It refers to the high steady-state quasi peak sound pressure level generated by the sound reinforcement system at the audience seat in the hall. The so-called quasi peak sound pressure level is the sound pressure level represented by the effective value of the steady-state harmonic signal sound pressure with the same peak value for non harmonic waveform sound.
Transmission frequency characteristics
When the amplification system reaches a high gain, the average steady-state sound pressure at each audience angle in the hall is relative to the amplitude frequency response of the sound pressure or input voltage of the amplification equipment at the microphone of the amplification system.
Higher available gain
The sound amplification system generates a critical gain of self-excited sound feedback in the hall minus 6dB.
Sound transmission gain
It refers to the difference between the average steady-state sound pressure level at each audience seat in the hall and the sound pressure level at the microphone of the amplification system when the amplification system reaches a high available gain.
sound field normniformity 
When there is sound reinforcement in the Li Hall, the difference in steady-state sound pressure level is obtained at each audience seat.
Haas effect
The listener only pays attention to the direction of the first arriving sound and ignores the direction of the short delay sounds that arrive successively, that is, the sound that usually arrives within 30ms will mix with the first sound. This phenomenon is called the "Haas effect"
