Speaker Cables Overview


There are several publications content and records displaying the results and opinions about the various types of speaker cables. Some specialized technical engineers have used their abilities to make measurements to validate successfully that there ARE versions between cords. A few authors have devoted their entire papers to the measurements and never talk about whether they have actually made any listening to tests or if they could pay attention to any modify. Despite all the measurements and opinions, one more test is whether you can pay attention to any modify or not. Obviously, this must be done under handled conditions where you don't know which cable is attached and there is no delay in switching.

In the early Eighties, special speaker cords were starting to appear on the market. Some of the claims were completely amazing and had costs to go with. Recognizing that cable level of level of resistance was the essential element in speaker cable, Gordon Gow, Us president of McIntosh Medical, used a speaker cable screen to show there was no listening to modify between these cords and simply variety cable. He offered his screen about the fact in speaker cable using a sport fishing reel of being cable to take a place on. Fifty-foot applications of cable were used in the assessment. The set up contains a professional control connect box and two cleaning connect containers. A three-position modify was used to choose one of three different speaker cords of comparative size.
Despite the potency of Gordon's cable display and the truth about presenter cable, people viewing the McIntosh room at the reveals, who had not knowledgeable the cable display, were disrupted that we were using normal hefty zip cable instead of one of the well-known manufacturers of presenter cable. Instead of enjoying the McIntosh audio speakers and gadgets, they remembered "bad" things they had been informed about "common" presenter cable and this marketed questions about the "inferior" cable being used. When we modified the cable to a well-known brand of cable, customers were happy with the installation, and instructed their attention to the McIntosh equipments such as home theater systems.

Speaker Cables Integral Part of Audio Systems

The link between the power amplifiers output terminals and speaker input terminals is almost good sort. It's regrettable that these important connections can be determined only by how tight you can turn a binding post or screwdriver or by the pressure of a spring which holds the speaker wire against the metal of terminal. The metals that are compelled against each other are often different. They could be brass or steel but plated with other metals. The cable could be copper or silver and perhaps coated with solder containing tin. They expand and contract differently with temperature. They can also become oxidized after some time and the connection can turn out to be bad to the point where the level of resistance is important compared to the level of resistance in the rest of the circuit. Different materials can also promote rust with action like a battery when they are in a humid environment. This ultimately causes not only higher resistance but also definitely audible distortion as if a diode were inserted in series with the speaker and amplifiers.


Assume you have a system with effectively heavy speaker cables but the cable connections go bad over time. Simply removing and washing the cables and gadgets and reconnecting them can make an audible difference. In addition, this occurs when an old cable is to be exchanged with a new "miracle" speaker cable. By distressing the terminals it can "unintentionally" increase the contacts when the new cable with its fresh surface is installed. A change can be heard but not because of the new cable. The same change can be heard by simply cleaning up the old cable/contacts and reconnecting them.
It appears to be sensible that rather than linking the output cables inside the power amplifier to the output terminals, the wires must be covered and soldered directly to the speaker cables. Then, consequently, the opposite end of the speaker cables should be covered and soldered directly to the speakers, or crossover network. This is not realistic, of course, unless the amplifiers and speakers are incorporated in the same cabinet.

Home Theater System Installation and Guide

Home Theater Systems

In current scenario where the time is very important to the peoples no one wants to go the theater to see the movies. The Home Theater System is a way that we can enjoy the movies at our own home. The home theater system is very different from the normal TV and we can watch the movies in our living room as like watch in theater. There are most of the peoples faces the problems during installation of the system in their living room or somewhere else. I am providing you some important points by which you can enjoy the movies with your home theater in a better ways.

Plan with Space: Before unpack the system first think about the space where you are going to put home theater system. Draw a simple chart with location for home theater system components.

Power System: Always choose a room with which is powered by one individual circuit breaker. Try the power extension if you don’t have enough circuits. These are helpful to avoid the power overloads.

Screen Placement: Screen placement is very important so always put the screen at the focal point and it always is the straight for the eyes.

Speaker Placement: Normally there are two types of speakers present in the home theater systems first is center channel speaker and second two normal speakers. For quality and clear sound hearing the center channel speaker must be just above or below form the screen and the two other speakers on the left and right from the screen at same distance.

Subwoofer and Bass Adjustment: The subwoofer will be placed at the side of the room approximately halfway between the screen and the optimal viewing position. The bass reaction can be manage by moving the subwoofer closer or further away from the wall.

User Manual Reading: Manual for the products is also very important and it varies from brand to brand. So before anything switch on you must read the user manual and do the process according to the manual.

The home theater selection is also a big deal for the users. If you want to buy the home theater system from any shop or from online stores please choose the right television, woofer and speakers. Also ensure which screen size is best suited for your home. Also see the software and drivers with your home theater system. Go for latest technologies and the most trusted brands which have lower price and better performance. You can also take some reviews offline from the friends and relatives which have theater system and online by different reviews websites. These points are most considerable because the home theater system is quite expansive.

Placement of home audio speakers

What do you think about home speaker placement??
Is this is a factor behind good sound quality??
Speakers size and design does matter??


these are few common questions which running in the users mind. What you think when you go for buy a speaker or when you already have bought home speaker and install it in your living place??

Yes you are right.

Placement of high end audio home speakers should be perfect and you have to buy your speakers according to your room size.
Speakers size and designs always does matter, It should be match with your room size. Its better first you know about the room size and consult with audio engineer on the audio shop and they will suggest the perfect design and size. You can install your home speakers with your own but it would be good if you take help from your audio engineer. Thanks...

Where distortion can creep into audio recordings

During audio recording there are a number of places where audio distortion can creep in. We are going to identify where these points in the recording chain are. Firstly a microphone will have a physical limitation as to how much it's diaphragm can move before it no longer represents the acoustic signal being produced. So ensure that the maximum SPL capability of your microphone is in excess of the instrument being recorded.


The next factor is the electronics in the mic, if this distorts you need to apply a pad switch if the mic has one. This will reduce the level of distortion in the mic.(and coming from the microphone) Then you will be plugged into a microphone preamplifier which in turn may distort, again you can use a microphone pad switch which often reduces the signal by 10 or 20dB so its good option for you. Sometimes microphone preamplifiers will have a pad switch built in as well, this can be useful if extra attenuation is required to keep the mic level down. Ensure that you have your gain structure correct on your microphone preamplifier signal meter, audio peaks should hit 0vu so there is some headroom if there are unexpected louder peaks. Ensure that you have your audio interface set to receive the correct level at the line inputs. (It may be possible to switch between +4dbu and -10dBv either on the audio card physically or within a software applet, +4dBu being a professional level standard and -10dBv being a semi-pro reference level.

When you record ensure you record at 24 resolution in your digital audio workstation and ensure that you signals peak around -18dBFS to -12dBFS on a digital meter, there is no need to record at a level any higher than this when recording at 24bit as the quality will still be very high. During mixing it will be a good plan to peak a kick drum at -18dBFS on the stereo ouput when you begin to mix the music. Balance the mix against this kick drum as a reference then you will not exceed digital zero and clip the output master bus (another potential form of distortion). By following the above guidelines you will have cleaner and clearer music recordings. It always be peaceful if you get clear audio recording.

Ultimately distortion is the result of a system or physical piece of equipment which has gone beyond it's design capabilities. Once the capability has been exceeded the device or system can no longer represent the audio signal in the system (or that to be recorded) with any accuracy. This is why in audio engineering schools there will be a big emphasis on not recording too hot and leaving sufficient headroom for the device in question. I hope these suggestion will help you to record distortion free audio.

Basics about audio integrated amplifiers and how they actually work

An integrated amplifier can sound a bit complicated to a lot of individuals, especially those who are not familiar with the basics. But the fact is that it is actually quite a simple as normal amplifiers. Consider audio integrated amplifiers as some sort of stereo receivers with no built-in radio tuners.

Basically, an integrated amplifier is a combination of typical amplifier and a preamplifier. Although a receiver allows you to connect all of your entertainment boxes such as your VCR, CD player, DVD player, game consoles, and your surround sound system, an integrated amplifier lets you connect all your electric devices for projecting as well as recording music.

An integrated audio amplifier is an electronic audio device or equipment that a lot of home music enthusiasts, professional musicians, as well as audio engineers regularly use. Since it combines features of preamplifier and an amplifier, it is actually quite convenient and easy to use. To make it more comprehensible for those who are not familiar with this type of device, we will explain what those two parts really do within the integrated amplifier.
The preamplifier is the one responsible for the reception and processing of the audio signal from the input source such as a DVD or CD player. If, for instance, the audio signal is particularly low or weak, the preamplifier adjusts the voltage to line level so that the amplifier can accurately accept the audio signal.

In addition, the preamplifier portion of the integrated amp is also where would typically input connections as well as operate controls. Every time you adjust the volume or switch program modes, you are actually operating the preamplifier portion of your integrated amplifier.

The amplifier, on the other hand, is the one responsible for amplifying the strength of the signal to significant levels, once the signal is processed and sent from the preamplifier to the amplifier. The amplifier is actually the one that will give your awesome speakers a hell of a workout. It has the capability to drive your speakers to its maximum potential.

The basic parts of an integrated amplifier are actually quite similar to receivers. Receivers are a combination of three basic components which includes an amplifier, a control center, and an AM/FM tuner.

The integrated amplifier, on the other hand, integrates a multi-channel amplifier and a preamplifier, otherwise known as a control amplifier, which is previously discussed. Integrated amplifiers usually do not have AM/FM tuners, as they are typically accompanied by a separate AM/FM tuner.

Audio integrated amps are quite rare when it comes to stereo systems. To a lot of consumers, stereo receivers, which consist of a radio tuner and sometimes a satellite radio, are more popular. However, many enthusiasts typically use separate preamplifiers and amplifiers, and separate tuners as well, if they wish to listen to the radio on their system.

Some people on the other side of the aisle do prefer integrated amplifiers over the separate ones for various reasons such as eliminating the clutter of excess connections, which can result in distortions, save some needed space, as well as cut costs on separate devices that may cause a mismatch in circuitry and design. Integrated amplifiers are mostly built for two-channel or stereo use, rather than for surround sound systems.
