Polarity And Gauge Determine Output Of Speaker Adapters
Listening pleasure is dependent on the sound of your device. Movies and whatever videos you are watching will never give you satisfaction without an audible and crisp sound. Would good sound be dependent on the device’s speaker? Or do speaker adapters contribute to the quality of sound delivered by the device? Many listeners are not aware on the role of speaker adapters, cables or terminals. Even the best and most expensive types of speakers will not deliver good sound with poor quality cables and connectors.
The speaker cables and speaker terminals are important links to any video viewing system. Inappropriate cable wires will adversely affect the sound delivered by the device. You might think that a cable’s worth is negligible. That is such a big blunder! The sound of the equipment is dependent on speaker quality which in turn is highly reliant on the quality of speaker adapter, cable and terminal.
You should know basic information on speaker adapters. The major factors affecting the speaker connectors are polarity and gauge. Do you know that each of your speakers (aren’t there two?) has a need for two lead interconnections to positive and negative ends of the receiver?
Polarity
Incorrect polarity will cause the speaker to be out-of-phase with the rest of the device. This is the reason why most speaker terminals, -ve and +ve, are color coded black and red, respectively. It is imperative that the required polarity be observed especially if the device is a multi-channel system such as a home theater. This equipment has surround sound where the quality of the audio is primarily essential. As such the polarity of the speaker adapters needs to be optimal.
Gauge
The wire in the speaker adapter or cable is measured by its gauge, which incidentally tells of the inherent thickness of the wire. The given normal thickness for wire is 18 to 10. The smaller the gauge number is, the thicker is the copper conductor of the wire. And the thicker it is, the better is the capacity to transmit amplified audio signal. Most speakers are equipped with gauge 18 and as this is quite thin, it can only be used optimally for short distance not exceeding 25 feet. For farther distance, a thicker wire gauge is recommended. This implies that your speaker gauge is dependent on the speaker wire length. The relationship of gauge and distance is given such as – less than 50 feet distance would require gauge 16, 50 to 100 feet distance would require gauge 14, 100 to 150 feet needs gauge 12 and more than 150 feet will command a gauge 10. The minimum recommended wire gauge for short distances is gauge 16 .
The guide to length factor is important in determining the quality output of the speaker. Many experts on this information recommend the adjustment to use the next higher gauge but choose one with 6 and 4 Ohms impedance speaker load.
Whenever it is time for you to choose a speaker adapter, be reminded of the guideline on the correct polarity and gauge of the cable or wire. Your audio device output as well as the speakers will not be able to deliver good sound unless you have chosen the right cable on the basis of polarity and gauge.
