How To Create Surround Sound

How To Create DOLBY sound circuit

TL072 IC

TL072 - Low-dead input range of high voltage range without latch-ups as compensation, high rate.  Internal frequency, high input barrier level at input level, low noise, low coherence harmonic distortion, output short circuit, late input bias and offset currents, wide general - dead and differential voltage ray.

TL074 IC

TL074 - Low sound JFET cord operation amplifier with high script rate, internal frequency with JFET input with high frequency handicap, low harmonic distortion, protection with JFET input, compensation.

MN3101 IC

MN 3101 - Bucket Brigade Dell (BBD) Clock Generator / Driver Two episodes of two episodes for drivers and a CMO oversized integration and 4-lead dual in-line plastic package, used as a single power.

MN3004 IC

MN3004 - A 512-level high-performance low-word BBD, which increases capacitor capacitance with equivalent chip zones, providing 85 dB signal within word ratio.

ABOUT SURROUND SOUND

Surround sound may not be a term to describe the different types of processes that produce an audio output where it enables the sound to return in full directions or to round the audience.  The system uses front and rear speakers with three or more channels to create directional audio noise and envelope surround sound.  The term has been widely used in recent years at the beginning of the Heim theater system, whether digital or analog.  The surround audio system includes several modes where audio is being amplified with a high quality reproduction with the addition of individual speakers through the audio channel.

Where is it used?

This circuit is often used as a specific decoder along with other basic functionality.  The first versions of Dolby Digital are Dolby 5. 1, it was replaced with DTS and other northern versions that support the transport and management level of digital sound signals.  For the key points of the method around Dolby, four-channel information within the two-channel signal, middle, back, forward left, and therefore front right, requires four-channel decoding made possible by the decoding chip which  Sends a signal to an acceptable destination.

What's dolby ?

Dolby Digital may be a brand operated by Dolby Laboratories for seamless audio compression where data compression and compression output are different than before, but in some ways still useful Dolby Digital monophonic, 2-channel, 4-channel  is.  Can be made as 1 channel or 6. 1 channel.  However, it should be noted that the Dolby digital phrase does not exclude the amount of channels involved, but rather the digital encoding of the audio signal.  However Dolby 5. 1 and 6. 1 are commonly mentioned as Dolby Digital in most common applications.

  To propagate words in additional directions, Dolby Digital 5. 1 stereo rear side channel.  Adding oils that make them more perfect and versatile.  These may overestimate the low frequency effect by adding a radical subwoofer channel.  Unlike Dolby Prize Logic for encoding and decoding Dolby Digital, a similar frequency range and power output is going to be an equivalent because the main channel where there is limited frequency response.

Types of Dolby

Dolby adds a channel in the middle and center of the channel and therefore the middle of the previous pages, using the Matrix technique, following other versions of Digital X, and using the Matrix technique.  Dolby Digital Sarker X which is 5..  The soundtrack provides a method for how to hold back channels in the middle for improved local results and economic;  Dolby Digital Live (DDL) which is an audio signal from Game Concession 5.  The 1 channel converts to Dolby Digital format and transfers it to Sony / Philips via the digital interstitial format.  Real-time hardware encoding is employed as (S / PDIF) only for interactive media within the flesh of video games;  Dolby Digital Plus, which is enhanced bitcoin, improved coding to reduce the composition industrial work.  Strategies, support for background and more audio channels in the background;  And Dolby to DD, an advanced loss audio codec that supports mandatory code for HD DVDs.

How does it work ?

The operation of the above circuit starts when the stereo sound signal is transporting word information along with the circuit's master volume.  This model will attach left channel LCH with TL072 IC1A and IC1B.  Where appropriate the channel is connected to the arch.  The outputs of this operational amplifiers will work because the input buffers as IC 2C left and right channels within the following stages of the circuit are going to be responsible for the synthesis of the central loudspeaker which will strengthen the output of the central loudspeaker when IC2D is encoded in two  .  The negative terminals within the channel back speaker have not been removed as they also ensure that they will connect only most speakers parallel.

The IC 2D output will power the audio controlled delay units in the rear loudspeakers.  This would give rise to suitable bribes of intervals according to the size of the house.  It will include the opaque sound delay signal IC5MN30000, which has 512 stages.  Since IC4 MN 3101 is a clocking signal, it provides time to IC5 as it acts as an oscillator of the circuit.  The variable capacitor circuit controls the delay time in the circuit.  The presence of circuit filters, to term during the process.  These filters can control frequencies above 4 kHz to 4 kHz and cut frequencies below 100 Hz to drive the rear speaker.  The rear loudspeaker is encoded by 100 kg of Herz as a 100-kilogram bandwidth.  The filters are built around IC6A / B which is the output buffer.  Helping with the combination and control of loudspeakers and amplifiers.  Each output is placed in a placenometer.  The power provided by the circuit can run 15V and every output can run a single energy amplifier.
