Buyer's Guide: Polarity Tester

Polarity Tester

CRY5616 Polarity Tester is a multi-functional, handheld tester for testing the acoustics of audio component systems. This equipment is especially useful for testing car audio systems, since it is capable of measuring both frequency and phase. This multi-functional tool is specifically designed to test both the front and rear of an audio component.

CRY5615 has two types of testing modes. In mode one, the test signal is measured at approximately 20 hertz. In mode two, the test signal is measured at approximately 400 hertz. If the output level falls below the test frequency, then it is an indication that there is a loss in the signal; however, if the level is higher than the test frequency, then it is an indication of high level of energy that is being radiated.

Most often, people use a polarity tester in their cars for listening to loud music or driving. It is also used in the workplace to test for compliance with work related policies. With an oem audio systems, it is necessary to check the quality of the speaker system for any signs of damage. If the speaker is not in good condition, it can lead to poor performance of the whole audio system.

An advantage of using an oem audio system with a built-in polarity tester is that the test signal is always from a clean source. In case of a connected speaker system, the test signal gets introduced in the output path. Therefore, there is an associated risk of introducing errors and distortion. On the contrary, a separate device is used for testing the output from the input source. This ensures accuracy in the measurement of low level signal.

There are several advantages in using a separate device for measuring power source like the OPA2. First of all, it has a very small size. It can easily fit on the desktop of a user. Secondly, it can be easily removed for servicing purposes. Thirdly, the built-in polarity tester does not require any external power source for its operation. This also makes it more compact and portable.

A useful tool in a mobile audio enthusiast's arsenal is the Polarity Tester. This handy device can be attached to a mobile phone or a compact disc player to test sound system efficiency. A variety of frequencies can be tested to reveal the power and efficiency of the speaker. The result can be displayed in simple text format or in graphical representation.

Some disadvantages of the built-in polarity tester are that they do not have an option to test speaker cables or connectors. The only option available is the separate power jack. The lack of power jack may pose a problem in some cases while transporting the audio system. Other disadvantages of the built-in tester are that they can only measure power and not sound system impedance.

The OPA2 model comes with two pulse generators, namely, the SMA style biased balanced pulse generator and the mono biased open pulse generator. The biased one produces output pulses whose polarity is opposite to the input pulse. While the open one produces output pulses whose polarity is the same as the input pulse.

One of the most popular OPA2 pulse testers is the Xlr by Crestaudio. The Xlr is capable of detecting high level amplitude of events. It has several additional features such as manual pulse width control, signal level indication, two levels for measuring low and high level audio signals, signal indication for standard headphones, lock/unlock button, user programmable led display and auto shutoff function. In addition, this pulse-tuner is very easy to install and use. It is compatible with almost all audio systems and can be connected to an existing head-set with ease.

The SMA biased balanced OPA2 speaker output pulse generator has excellent performance. Low level audio signals are easily detected. This pulse generator works well with most kinds of head-phones and headphone sets. It is capable of measuring high frequency, low level pulse and any other polarity.

One of the latest generation of OPA2 biased speaker output tester is the XBEL. The XBEL is a multi -functional tester that not only measures and displays output pulse, it also serves as an accurate power analyzer. With the XBEL, the distance of the output signal from the speaker to the measuring probe can be precisely determined. Besides the above, this multi -functional tester is available in two variants - mono or dual mode. In addition, this OPA2 biased speaker output tester has a built-in speaker isolation feature.
