Speakers are most likely to suffer from improper use. The enclosure can be damaged or come unglued. The speaker can blow an electrical or thermalfuse. Wiring can be faulty. The voice coil can be faulty, a speaker can be blown, a crossover network can be faulty, or a solder connection c...
I mounted my amp in the front trunk, which gives short cable runs to the speakers, head unit, and battery. It's also a less obvious location for thieves to look. The downside is the potential for noise from the various electronics mounted up there, particularly the power steering. ...
In order to follow this tutorial, you need: Some programming experience with C++, Java or similar programming languages, if you are not, there will be some help provided by the tutorial, but please refer to the electronics and programming resources section. Some electronics knowledge, you need ...
Often, the problem is not in the amplifier but in one of the connections between it and either a source or the speakers. Use a continuity tester or a multimeter to check continuity of audio cords going in and out of the amplifier before attempting to open the unit up and look further. ...
If you're ever unsure if the solder joint you created is making an electrical connection, you can use a multimeter to test forcontinuity. Holding Headers Against a Board For those that have the dexterity, you can install a row of headers by holding the pins against the board! You can try...
Power cord wire colors are sometimes non-standard so use a multimeter to identify Hot and Neutral. Europeans sometimes use the letters E: Earth (safety ground), L: Line (hot) and N: Neutral to describe the three plug wires.The 325 volts AC power from the power transformer is fed ...
Sometimes it can be hard to know if you've got this right. One way to check is to listen to some music that you know plays certain passages or instruments mainly on the left or the right channel with speakers or other phones. (If Slash's guitar solo is in your left ear before you...
Bench-testing with a multimeter serves the same purpose.LiPo Battery WarningThis project is essentially a toy, but it uses an RC-grade LiPo (Lithium Polymer) battery and power system that can be dangerous if mishandled. The voltage is safe for humans, but there is enough power (20 Amps, ...
A resistance is a DC resistance, which can be measured with an ohmmeter. If there is a capacitor in the signal path we measure nothing. With a voice coil of a speaker we can measure a DC resistance. With a digital multimeter DMM resistances can be measured easily, but we cannot measure...
It is a device that converts one form of energy into another form of energy. Pressure sensors, light bulbs, speakers are all examples of transducers, since they all convert energy from one form to another. So how does microphone classify as a transducer?
