about sound The topic of this text is a review common implementation options audio final amplifier for computer. typically audio outputs A, B and C music coprocessor connected to mixer that forms stereo balance and required amplitude levels. after this sound is output to some peripheral connector for connecting to the amplifier. There are two types of amplifiers - soldered and ready. we won't consider the first ones we will, just because. Ready-made amplifiers include: - TV audio - final stage of the tape recorder amplifier R - red G - green B - blue VIDEO/SYNC - video/sync mix AUDIO - sound GND - ground if the TV is black and white, then RGB is not connect.the TV may have a socket type tape recorder, scart type connector or just video and audio inputs. the first option connects connecting signals of the same name computer and TV using cable. the second option is not similar to the first, only on some TVs for normal work needs to be given some kind of signal the same scart some level. The third option is not very successful. you can simply connect a video signal, in The result will be a black and white image. for it to become colored, you need connect R, G and B to inputs video amplifiers. It should be noted that all amplifiers audio frequency of television and audio equipment were designed specifically for reinforcement sound, so they have quite normal characteristics. 2. TAPE PLAYER, MUSIC CENTER, PLAYER Such devices consist of preampand final. pre-amplifies the signal with magnetic head, piezoceramic pickup, etc. terminal amplifier - powerful, works directly to the speakers. between them various equalizers included, volume controls, etc. some devices have the so-called. line input - it goes directly to the input volume control and then - to low. The audio output of the computer must be connected right here. if there is no entrance, it is removed do. for example, you can connect to one of the outputs of the volume control or find the input on the board (there may be space for the connector or even itself unused connector). note that almost all amplifiers in audio equipment are high quality and suitable for playing sound from a computer. 3. AMPLIFIER amplifiers are a box with various inputs and outputs as well as regulators and light bulbs. They are also intended to enhance sound and have different output power. some amplifiers contain preamplifier - e.g. for microphone. the amplifier has a high output power and adjustability stereo balance, low and high frequencies, and some - and equalizers for fine tuning gain across frequency bands. 4. SPEAKERS FOR ibm PC CLASS COMPUTER these devices are usually connected to pussy and placed on the sides of the monitor. These speakers contain amplifiers and require food. ps-shny speakers, despite everything there is a variety of them, there are two types: SHIT and NICE. it's quite easy to identify the first ones simple: they have small speakers diameter, and, as a result, are unable reproduce with acceptable quality the entire frequency range of musical coprocessor. speakers like SHIT can be equipped with a tone control and button typebass connecting parallel to the input capacitor. but This does not improve the sound quality, so Speakers of this type are not suitable for use with a Spectrum computer, but can be used (and are used) on PC to play service Windows sounds. NISHTYAK type speakers have a size of order more columns like SHIT due to the use of speakers there larger diameter. sound quality depends on the speaker directly. the larger its diameter, the range expands more frequencies reproduced by it in the area low. LOW FREQUENCIES IN THE SPECTRUM ARE ENVELOPE, DRUMS, AND NOTES ON 1 AND 2 OKABAX. for the most part they give Spectrum music its unique lovely. NISHTYAK type speakers can also have tone and bass boost control frequencies, which is similar to similar chips in tape recorders, music centers, etc. Note about speaker size (or - columns as a whole) is valid for any sound reproducing equipment,therefore you need to take this into account when designing your audio system if you want good quality sound. chips like extra-bass also should not be neglected. it should be remembered that good sound gives your computer even more SPECTRUM charms and more rules! :)
