Question about Crate FlexWave FW15 Guitar Amp Combo, 15 Watt Single 8 Speaker

I have a crate PA 8 and it makes a crackling noise when I play through it. I hooked the speakers to my other amp and they sound good, I hooked the PA to my marshall cab and it still has the noise, so I don't think it's blown speakers . Nothing inside looks burned or anything, what do you think??

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.

My Roland FP8 plays very quietly through its own speakers, through an external amp & speaker and through the earphones. There is a hissing/crackling/static sound too from the speakers. Anyone

A number if things can be wrong with it, from the audil preamp to the the audio amplifier. Even as simple as a bad volume control. Does the actual noise change patterns when you move the volume?

Are all the tubes lighting up? they should glow like dim light bulbs. If not, replace them with the same model type (12ax7, or EL34 for example).

Often there are two fuses, one to protect the speaker and another to protect everything, it sounds like the latter fuse may be burned out. take it out and take it to radio Shack for exact replacement.

I have Behinger Europort EPA900, One speaker crackles, tried swopping cables etc, but nothing helps, the problem seems to be definitely with the speaker.

Open the speaker and look for loose connections. Carefully move cone with fingers. If there is noise when doing so...rubbing type noise, speaker needs reconing or replacing. If the crackling comes from teh tweeter section, then the tweeter may need replacing.

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.

I have a Crate PA-8 4 ohm 150 watt PA head that I run to four Peavy 10" PA speakers (two per side in series). It was very good, clean sound, but the speakers were cheap and may have been pushed too hard -...

150 watts should be easily handled by four Peavey speakers in the connection you described.. If the Peavey's are 8 ohms, then your total load was 8 ohms for the series/parallel arrangement which is well within the 2 ohm drive capability of the Crate according to specs.

I question if you really mean the speakers were in series? This requires a special cable to do this. Now if you mean they were "daisy chained" like the amp went to one speaker and another cable connected that speaker to another, then you REALLY had ALL speakers in parallel electrically which would be at the 2 ohm low limit of the amp... In either case, with only 1/4 of the 150 Watts to each, the speakers should NOT have been damaged. The amp MAY have been damaged. Try each speaker individually at a REASONABLE level to test.

If you plug into the effects loop out jack,OFTEN the connection to the internal power amp is broken so you might have to arrange a special cable as a wye to go back into the power amp as well as your external amp. In any case pwere ALL interconnected amps, etc from the same power source/receptacle for system safety.

Crate Bass Amp B100 - No sound.

Do you happen to have another speaker that you could hook up to speaker output? This would bypass the amps internal speaker and lf you get sound from that setup, it would mean either a jack failure or possible internal speaker problems. Please let me know.

Make sure the "ground lift" option is used on the direct box.

DO NOT UNDER ANY CIRCUMSTANCES use a headphone output jack as the output of this unit. The headphone jack is for HEADPHONES that have no return to ground. Use of this as drive to a sound board is sure to cause problems and in some cases can fry these amps due to the circuitry.

The cable used to go to the direct box should be very short and high quality.

You should source the power for this unit from the SAME source and receptacle as your sound board if at all possible.

I have a Crate PA-8 that hasn't been used in a long time. I destress and sing. Anyoo it has a power issue. Light is flashing on then goes off. I can't find a manual. Can anyone assist me please?

you have either a failing fuse or a failing power transformer. take out the screws on the top of the amp, leave the handle in tact and pull out the chasis. look at your fuse to see if it is in its holder correctly, and see if the fuse is burnt. the correct fuse values will be printed on the circuit board. if the fuse looks good then, it may be the power tranny going south.

Plugging line level into my crate TX15. all inputs sound distort

guitar amps are all set to a low Z resistance configuration. wich are made for guitar only. make sure you are using the right cables.
you need sheilded guitar cable not unshielded speaker cable in many cases these cables look exactly the same. look at your cable look for the words speaker or instrument. you need the instrument cable. if you still have that problem. then you may just not be satisfied with the quality of the amp it self.
