It is likely that there is a failure of one of the amps in the unit. It could be a cracked circuit board, bad solder, bad volume control, or a bad compnent in the power amp section for one side. HOWEVER something does NOT compute here as you can't connect more than one speaker to a 15 Watt Crate amp... Maybe you have two of these amps.

Mic output of my pmp3000 is weak,levels must all the way up to get any mic sound louder,Im using balanced xlr's for my mics, Is there any adjustable sensitivity adjustment inside the mixer? like the...


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/

I have a Crate GT 15, not getting anything to the speaker when I plug in.


Do you have electronics experience? Inspect the amp for broken or cold solder joints and any burned components. Check to see if the fuse blew and that the output IC's or transistors (not sure what Crate used in these) are not bad. Check your speaker wire as well.

Hi

The problem is with the amplifier itself. Crackling is usually capacitor related and you will need to have the amp checked over to properly identify the cause.

Some amps are also prone to pick up static from other electrical items which can also cause these problems. I had a crackling issue with an old Crate amp of mine which turned out it was due to being too near a computer/monitor so it is worth eliminating these things as a possible cause before having the amp checked.

Hope this helps. Thanks for using FixYa.

Amplification


You need to now the RMS for a true capacity of your speakers and your amp.

I would say you are OK, with a margin, but if you turn the amp to max and blow the speakers, please dont call me.

I know this is a very broad statement, but your budget will allow for what you buy. You will want a nice 2 channel 50 watt rms amp min. 50 watts is a lot of power for those speakers and you will be happy. I would recommend if your budget allowed a nice kenwood, Alpine, Diamond Audio or MB quart. Just make sure whatever you buy that it is a low noise A/B class amp. Nothing to special.

Take care and have fun!!

Noisy/buzz


Usally a ground loop isolator will fix that problem. It plugs into the RCA's between the radio and the amp.

Try to reground the amp in a different spot.

Or run a refrence ground from the deck to the amp next to the remote turn on wire. (still keep your main amp ground hooked up)

DO NOT run your power wire next to the RCA's, that will induce a field which in turn can cause that buzzing sound.

When the bass cut on the speakers cut off


220 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms)
the amplifier may be over-driven. are there red protection lights coming on the front panel? Or a loose wire - power, ground, or speaker.
