A faulty volume potentiometer? Some internal cross-talk? Free wires induction because they are too close, inside? It sounds possible to me and a minor problem. Don't worry too much.

SOURCE: how can i upgrade my av 302 to becomes best as

Hi,
upgrade your 302 to 502 need to replaced the toroid transformer, set of output amplifier, set of electrolytic capacitor.
Purchasing of these parts one-by-one is much expensive rather that you buy a brad new Konzert AV-502. Also upgrading the unit is quite tech and need a lot of experienced in electronics.
Hope that it may help you.
Have a nice day.

SOURCE: I have a konzert 302, just the other day I was wondering why the left speaker sound is disorted and very scratchy. I Thought it was only my speakers but I check and found out it was from the left chan

If you intend to DIY , check for possible cold solder joints,

leaky transistors , changed-value resistor.


Upgrade to 502 it is better than the one you have.

Konzert amplifier av 302


200 watts is the output, home use or commercial? not a good amp to run at its max as it has a low reserve headroom. for home use 100 watts rms is more than enough.

Konzert amplifier av 302 can i use 4pcs of 200watts speaker in that amp


It depends on the impedance of the speakers, if you use (2) 8 ohms speaker on each channel the load will be 4 ohms if you use (2) 4 ohms the load will be 2 ohms , check and see what load the amp can handle.

I just received my RSQ-echo 2000 karaoke machine. When I plug a mic into the front 2 mic inputs, they both have echo, even tho I turned off the echo volume in the back. I assumed that by turning it all...


The control supposedly controls the mix of the echo... this is a reverb type sound. Please note that room acoustics AND if the mic's "hear" the speaker in this, it may create an echo that is NOT under control of the adjustment. Make sure the mic's cannot "hear" the speaker or a reflection off a wall.
