Buying a loud speaker amplifier can be a daunting task, especially for beginners. Understanding common pitfalls can help you make a more informed decision and avoid wasting money on the wrong equipment. Today, we're looking at loud speaker amplifiers: what they are, mistakes people make when buying, and some sample models from all price ranges.
Defining Loud Speaker Amplifier
First, a definition and a distinction. Loud speaker amplifiers are electronic devices that increase the power of audio signals to drive loudspeakers, ensuring clear and powerful sound output. They differ from speakers and loudspeakers. Loud speaker amplifiers boost (or "amplify) audio signals while speakers and loudspeakers convert electrical signals into soundwaves to create the audio you hear.
When setting up an audio system, it's crucial to match the right amplifier with the right speakers. Using a mismatched pair can lead to poor audio quality or even damage your equipment. It’s essential to understand this distinction to avoid costly mistakes.
Mistake #1: Getting the Wrong Power Output
One of the most critical specifications is power output, usually measured in watts. Power output determines how loud and clear the amplifier can drive the speakers and selecting the wrong power output for your speakers can lead to major issues.
Ensure the amplifier's power output matches or slightly exceeds the speakers' power handling capacity. If you go too much or too little either way, the sound will be compromised. You can also potentially damage the speakers.
Mistake #2: Mismatching Impedance
Impedance is another vital specification, usually measured in ohms. Amplifiers and speakers should have compatible impedance ratings to function efficiently. Mismatching the impedance can lead to major drops in sound quality and can potentially damage the speaker.
Luckily, models like the Cloud Electronics VMA240 2U Mixer Amplifier, with its versatile impedance matching capabilities, can work seamlessly with various speaker types, making it a flexible choice for different setups.
Mistake #3: Ignoring Signal-to-Noise Ratio (SNR)
SNR is crucial for determining the clarity of the sound. Higher SNR values mean less background noise. Always look for amplifiers with higher SNR values to minimize hiss and hum. Ignoring this stat means you may get a dirty signal that sounds wrong and full of static. Finding a high SNR means you'll get a clearer signal overall.
