Why Your Karaoke Active Speaker Sounds Raspy: 3 Causes
An active speaker raspy sound can come from the amplifier section, the tone control or the input source. Check these three causes before buying a new one.
If you own an active speaker, a raspy sound is bound to be annoying. The output has unclear articulation, a bit like listening to the radio when the sound comes out as if the signal has dropped. There are, of course, reasons a karaoke active speaker sounds raspy. Read on for the details.
What Makes an Active Speaker Sound Raspy
- Amplifier Section
One thing that can make an active speaker sound raspy is the amplifier section. Faults often occur in this part, and one symptom is the raspy sound the amplifier section produces. Of course, this makes anyone uncomfortable.
To fix it, you need to understand a few things so the speaker can sound the way it did before. You need to know how to measure and check the transistor legs, and you also need to understand the signs of a faulty transistor.
- Tone Control Section
Another thing that can make a karaoke active speaker sound raspy is the tone control section. Note that it is rare for this part to be the cause of a raspy sound in an active speaker, but it cannot be ruled out.
You can tell when the tone control is faulty, though. One sign is sound that cuts in and out. You may also hear a humming sound. Another sign is a potentiometer, the volume knob, that crackles or does not turn smoothly when the volume is adjusted.
- The Input Source
Another cause can also give this audio device a raspy sound: an external factor that is easy to overlook. When the karaoke active speaker is taken to a repair technician, the sound it produces is normal and not raspy.
But once it is taken home, the sound from the active speaker turns raspy again. After some investigating, the cause turned out to be the input source, the DVD player. The raspy sound came from a damaged DVD cable.
So if your active speaker is faulty or sounds raspy, it is best to find out first what is damaging the audio device. But if you want to buy a new one, Bliaudio.com can be the right store for the best-quality active speakers for karaoke.
