Konzert AV502a (500watts per channel) + Konzert 600 watts speakers Will I not have problem with this setup? I heard that my amp should have higher wattage than my speakers.. Pls advise..

YES YOU CAN CONNECT

Speakers are rated either at RMS (root mean square) average power or Peak Power. An RMS of about 125 watt is equivalent to 250 watt peak. To match the radio and speakers they both need to be consistent. Also do not be confused with total radio power out vs per channel.

So if the speakers are 250 watt peak power then a radio with 125 watt per channel or 250 watt peak per channel would be a good match.
If the speakers are RMS 250 watt then the radio would be 250 RMS/channel and usually with a four channel radio a total of 1000W RMS
With that much power the neighbors should hear you coming!

You don't give us much to go on. What happened last before you discovered your amp had no sound? Did the speaker wires cross with exposed metal? In other words, did you short out your amp by touching the negative speaker wire with the positive speaker wire? That will "Fry" your unit. Did you check the fuse? I assume you have a good power cord that is properly plugged in. Does your amp light up when turned on? What other issues can you tell us to give us more clues so we can help you?

That amp is rated at 400 to 600 watts per channel depending on the speaker impedence.

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.

The answer to your question is NO, there is NOT an internal adjustment.

For many mics the trim is used full clockwise. Some higher output mics I use the trims are run at 3 o'clock which is mostly turned up. This is NORMAL for most mixers. If you don't have enough mic gain relative to other inputs, the fault is balancing the other inputs down and using higher setting on your MAIN slider.

If you use 8 ohm speakers then you can expect to get about 200 Watts of audio per side with this amp. You can get about 400 Watts RMS (600 Watts peak) using 4 ohm speakers.

The efficiency of the speakers makes a lot of difference in the sound level output/

You will not be able to do that with a 4 channel amp. You can with a two channel amp, but not a 4 channel amp. You can get, depending on the amp, 300 from half of the amp to one speaker.

You are probably aware on how to use these output figures, but I'll write a quick explanation on the specifications for future readers anyways :)

The concpet CC-452 amplifier has the following power output specifications:

Calculated at 14.5 volts DC;

At 4 ohms per channel - 45 watts x 2 (RMS)
At 2 ohms per channel - 70 watts x 2 (RMS)
At 4 ohms bridged - 150 watts x 1 (RMS)


This means that your amplifier would provide 45 watts of power each for your front speakers, which are normally a 4 ohm load per side (45 watts for left, 45 watts for right), that's unless they are one of those exotic higher end brands (eg: Boston Z6s which are 3 ohms). Rarely, you will find speakers that are rated at 2 ohms per side, but in this instance the amplifier will provide 70 watts of power into each speaker. On your speaker specifications, you will find a value termed "nominal impedance" which will give you the ohm rating of the speakers being used..

On the other hand, if you "bridge" both channels into a single channel (using a diagram often marked on the speaker terminals of the amp), you could then provide 150 watts into a subwoofer (providing it was a 4 ohm woofer).

It's not recommended to use this amp bridged under 4 ohms..

Some subwoofers may be lower than 4 ohms, and you will not be able to use this amplifier for these types of speakers without risking amplifier failure. Also, some subwoofers may have 2 seperate voice coils, and you will have to use both channels of the amplifier seperately (not bridged) in order to correctly connect this type of speaker for use.

First of all the EXA-3940 is rated at 350watts per channel in to 8 ohms. The 1400 watts is bridged into a 4 ohm load. Second, the speakers can handle 1000Wats peak with an average of 600 continuous (i'm guessing). That tells me that the amp is underpowered for the speakers. The sensitivity of the amp is such that the mixer is overdriving the input stage. That is what is causing the clipping. If you are looking for more volume, you are probably better off purchasing another amp and running them in bridge mode, 1 per speaker cab. Be careful though, not to overdrive the speaker cabinets either.

Provided your sub can run at a lower impedence its better to tun them in parallel.... you do not need a stereo bass effect!
