When I plug-in my vp1220f floor monitors in to the monitor mix on the pmp 2000 i get no sound or little sounds


If you are referring to the "monitor" output , this is a Pre-amp output which connects to a power amp or speakers that have built-in power amps. The Monitor output is a high impedance output. This output will not drive speakers directly.

It sounds distorted when the music gets louder


Time to start upgrading! Think power delivery, then amps, then speakers, then enclosures.
If you need more voltage, add batteries, capactors etc, if you're exceedingg the amp output range, you'll blow speakers (no matter what the speakers are rated for), if you have good power and the amp(s) are fine, your speakers may not be up to the task

Marshall MB4410, with low volume gives no real volume,


Guitar amps have preamp sections (think unpowered audio mixer) and power amp sections (Crown rack-mount amp). An excellent way to isolate audio problems if amp is still producing audio is to check the preamp out (line out). Preamp output distorted = preamp failure. Connect MP3 player to "Power Amp In"...sound distorted = power amp failure. In your case the latter is the case as your "line out" is clean. Also test each speaker for clear sound as speaker cone damage from being overpowered is fairly common. At 300w. I'll assume the failure was not from cranking the volume to loud but a shorted speaker or speaker wiring could zap the power amp in an instant.

How can i get more power through 8 ohm speakers?


In addition to the impedance rating of a speaker, there is also a wattage rating. Ideally, power output of the amplifier should not exceed the power handling rating of the speakers. The input impedance of the speakers should match the amplifier output impedance for maximum power transfer (Rin = Rout where R is resistance in Ohms). Supplying more power or wattage to the speaker than it can handle will result in distortion, and if the output of the amp is high enough and present long enough, it will damage the voice coil of the speaker. Make sure that when comparing wattage ratings, you are comparing the same rating between amps & speakers. Watts can be expressed three different ways: "Peak", "Peak to Peak" and the industry standard "RMS". The relationship is such: an industry standard value of "70 Watts RMS" (70W RMS) equals "100 Watts Peak" (100W P) *and* also is the same as "200 Watts Peak to Peak" (200W P-P). Furthermore, there is no such thing as 200W "Music Power" (but is often expressed this way to inflate the RMS wattage rating (and usually is close to the P-P rating). A speaker is an electrical device, so most the things that happen to electrical devices when over powered can happen to speakers and amplifiers, too.

Increasing the signal source level (input signal to the amp via volume control) in an attempt to get more audio power to the speaker can overdrive the amplifier - resulting in "clipping". This is plainly heard as "muddied" sound. The otherwise loud, crisp, clean passages in music end up sounding garbled and unpleasant when an amplifier is over driven in this way. This can damage both the amp and the speaker.

Cheap amps with higher THD (total harmonic distortion) ratings sound worse than their counterparts with a lower THD rating - when all other variables are the same. You'll pay extra for lower THD values.

You might be able to make a speaker seem louder by positioning the speakers against a wall, on the floor, etc. Experiment; as it can make a significant difference in sound levels and low frequency bass sounds.

I hope this was helpful!

No sound from speakers, but there is power to amp


make sure the power wire and the remote wire have voltage. at least 12 volts. make sure the ground wire is good and has a good solid ground. after that make sure the rca cables are getting signal from the radio. if you have a small speaker or tweeter you can touch the wires from the speaker to the rca cables and it should play music very quietly. meter the subs and make sure theyre ok and not shorted or bad. if all that checks out good.... the amp is probably bad. start with all the simple stuff and work youre way up. if the amp has good power and signal and good speakers then the only thing thats left is the amp. good luck

NO sound through the AMP even though the power light comes on


Not a fuse. First thing, to check your speaker (amp unplugged, of course), touch the + and - speaker connections to a 9V battery. If you don't hear a pop sound then your speaker is blown. Thus, no output sound. If speaker is OK, then the output IC is your problem.

My amp overheated on a Klipsch promedia 2.1


Sounds like your speakers had too many watts sucking from an amp that couldn't produce the power to feed them.
What is the max watt power output rating for your amp?
Compare the amperage of all the speakers combined and make sure they are 15% lower that the rating on your amp. Be sure to include the sub in your totals.
Chances are you've blown the power supply on your amp.
Have you tried any of these checks yet?

Speakers are connected to pre-amp or power-amp? pls explain connections , what connects with what , between cd player + pre amp + power amp + speakers.


Do this, CD audio out jacks to the PRE-AMP INPUT jacks, then PRE-AMP OUT jacks to AMPLIFIER INPUTS then from AMPLIFIER to speakers, This will work similiar with any sound source unit ie. Radio Tuner, Tape deck, etc. Just think of it this way, a PRE-AMP is BEFORE the AMPLIFIER, all the AMPLIFIER is going to do is AMPLIFY the sound to your speakers, HOPE THIS HELPS!

No sound with the front speakers


Sound to headphones comes from the pre-amp stage of most units otherwise they wouldnt be able to handle the power output . 150 watts into your ears ouch lol .
So it sounds like your slave amp has gone down on one channel . a slave amp is the final output stage and the power stage to the speakers . to make sure it is the amp change your speakers over if the sound then works from the speakers that had been dead then its the amp and requires an engineer to check it out with the prospect of a new output IC or final stage / capacitor replacement

unskilled persons should not attempt to repair electronic equipment as it is unsafe to do so , and may cost you far more in the long run ?. Regards Vortash
