The common English symbols of high-end audio are explained in detail. Imported high-end combination audio is gradually entering the family. The function symbols of these original imported audio panels are all in English, which brings inconvenience to the use. In order to provide convenience for the correct operation of many users, the English mark symbols of imported famous brand audios are collected for explanation and functional explanation. These Chinese and English comparison instructions will definitely benefit the Hi-Fi enthusiasts after reading.
1. Tuner tuner
FM Antenna FM antenna: divided into 300Ω and 75Ω impedance. AM loop antenna: suitable for mid-band. DS Button "Write" frequency digital button: You can directly write the stations that already know the band and frequency using the 0-9 numeric keys. Once the writing is correct, the tuner immediately transfers to the station to work. * If it is wrong , Then "Error" is displayed, prompting the user to perform the operation correctly again. FM AUTO button: When the fluorescent screen lights up "AUTO", it automatically converts to stereo; when the signal is weak, it automatically converts to mono, and Stereo goes out. StaTIoncall name selection: select the preset FM or AM station that has been stored in the corresponding number key; or store the station to be memorized through the staTIoncall number key. Control out jack control output jack: generally connected with amplifiers, dual decks, turntables, (CD) turntables, its shape is a flat cable jack, some machines also have SR mark.
2. Ggraphic Equalizer
Flat reverse switch Flat / reverse switch: set the "flat" position, the EQ curve will all return to the flat (0dB) position; set the "reverse" position, the EQ curve is controlled by the level of each frequency increase or decrease. flat / reverse corresponds to instructions on the screen at the same time. memory recall switch: Press this switch to recall the stored EQ curve. PHONES earphones: This EQ curve is designed to hear stereo playback during tape recording. VOCAL voice: This EQ curve is designed for listening to voice and music. HEAVY accentuation: This EQ curve is designed for listening to rock * music, especially bass and treble accentuation. CLEAR: This EQ curve is designed for listening to electronic music to obtain clear sound, and specifically strengthens the midrange and treble characteristics.
Three, amplifier amplifier
CD direct switch indicator CD direct switch / direction: the direct connection of the CD player signal amplifier, that is, without any modification to the CD source, skip the equalizer, this function is indicated by the LED. DBFB Dynamic bassfeed back dynamic bass feedback system: is a function that automatically enhances the bass as the volume decreases. After pressing this key, the LED will give corresponding instructions. DSL dynamic super loudness system: Its function is similar to DBFB. AFBS acousTIc feedback system: use the feedback of the acoustic system in the speakers to enhance the bass. delay control Delay control: It is a surround sound delay processing function. There are four delay times from 10 ms to 20 ms to 30 ms to 00, which are indicated by LEDs.
4. Cassette tape deck
ASES auto synchro ediTIng systemswitch automatic synchronization editing system: this function can automatically transcribe CD signal on the tape, there are three editing functions. FADE gradually disappears: press this key, the sound will go from loud to soft until the sound disappears. This function is used for recording. The CD source can be segmented (edited) on the tape. The CD signal has not ended and the tape has run to the end. This is an editing and recording method. The entire FADE process is about 10 seconds, and 2 seconds before the end of this function is a blank area with no signal. PARALLEL simultaneous recording: when both decks have the recording function, you can record at the same time. Quick reverse: With the function of the two-way deck, the time from side A to side B ≤0.6 seconds, while ordinary automatic reversal takes about 6 seconds. Dolby HXpro Dolby dynamic bias: during recording, the bias current is automatically adjusted with the amplitude of the high-frequency signal, eliminating the background noise of the tape, can expand the high-frequency response, improve the signal-to-noise ratio, and reduce
Metal oxide semiconductor field effect (MOS) transistors can be divided into N-channel and P-channel. P-channel silicon MOS field-effect transistors have two P+ regions on the N-type silicon substrate, which are called source and The drain is not conductive between the two poles, and when a sufficient positive voltage (gate ground) is applied to the source, the surface of the N-type silicon under the gate exhibits a P-type inversion layer, which becomes a channel connecting the source and the drain. . Changing the gate voltage changes the density of the holes in the channel, thereby changing the resistance of the channel. Such a MOS Field Effect Transistor is called a P-channel enhancement type field effect transistor. If the surface of the N-type silicon substrate is free of gate voltage, the P-type inversion layer channel already exists, and the appropriate bias voltage can increase or decrease the resistance of the channel. Such a MOS field effect transistor is referred to as a P-channel depletion field effect transistor. They are collectively referred to as PMOS transistors.
