I have a set of M Audio StudioPro 3s, the powered speaker fell straight on its volume knob, and now doesn't work. the speaker will still output just a squeak of sound, probably the passive amount that my ipod outputs. Turning the volume knob up and down does nothing to this volume, just stays at that same low volume. whats your take? sounds like the amplifier is broken within the speaker. When I connect it up to the non-powered speaker, it behaves just like the powered speaker too.

is it possible that you may have plugged the speakers into the microphone or audio input jack on the computer instead of the speaker/headphone/audio output jack?

try to reset. Unplug the unit, press and hold speaker A and speaker B buttons and plug the unit in outlet. If doesn't help, the unit may have a problem with microprocessor or dsp boad and need to be serviced at a repair shop.

Hello,

Let verify first to narrow down to where the problem can be. First, check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. To get the sound repair, it can be from $150 and up, so if you can put up with using the good set of Powered PC speakers which actually give better sound than the tiny speakers inside the TV, I would keep using it that way, you may want to find out if the on screen sound setup will allow you to set the audio line out to be VARIABLE which means the sound output feeding the PC speakers can be varied using the TV remote control, then all you have to do is to set the PC volume to about half way up and set the TV volume to what ever you want.

Take care in solving the problem....

You didn't give the brand and model of your TV, and I can't try to find a manual and see what kind of AV connections it has available. So here's some general information.

Many TV sets only have input jacks for external sources like DVD players or cable boxes. When you select an external source, or use the set's internal tuner for TV programming, the video and audio play through the TV. The trouble is that if the set has no audio output jacks, there's no way to get a sound signal out. The TV accepts only inputs

When the TV is part of a home theater system, most people use it just as a video monitor. All AV sources connect to the receiver, and audio is sent from there to the speakers. A video output from the receiver goes to the TV so you can see the picture, and the TV's speakers aren't used. If you have a cable box, FiOS set-top box or satellite receiver for your TV channels, they connect to the receiver too, since they're just another external source.

This doesn't work if you rely on the TV's internal tuner for TV channels, though. This might be the case, for instance, if you have a cable system where a converter box isn't required and your cable connects right to the TV. When you're watching regular TV, then, the sound comes through the set's internal speakers. If there's no audio output available on your TV, that's your only option.

As I said earlier, many TV's have only audio inputs. But some have audio output jacks as well, so the sound has a way out. If yours does, you can connect them to one of the inputs on the home theater receiver. Then when you select that input you'll get the TV sound through the speakers connected to the receiver. Depending on the design of the TV, you may need to leave the TV volume turned up. Some sets have outputs that are follow the TV's volume setting. On others, the output is an independent fixed level. Then you can turn the TV volume down and use just the receiver's speakers if you want.

Check the connections available on your TV and look for a set of "audio out" jacks. Your TV's owner's manual should have a section explaining how to connect it in different ways. If you need a copy, most manufacturers have manuals for download on their website.

Good luck with your sound, and thanks for using Fixya!

you can get the know right from the dealer at this link http://us.marantz.com/us/Support/Pages/ServiceCenter.aspx as far as the one speaker working, switch the speakers to make sure its the unit and not the speaker box, if that doesn't help you probably have a blown output in the unit itself,, since its a Marantz Its worth the cost of having it repaired,, as with all High end receivers or amps, Be sure the unit is in the off position before you attach or disconnect any speakers ,, if they short out,, our gonna blow the output

Make sure you are using BALANCED line to this... XLR connections boyh ends. Make sure ALL interconnected devices are powered from the same receptacle or power conditioner. Test your cables... they do go bad. This unit REQUIRES line level input. Do NOT expect a mic to drive it directely. Make sure your mixer uses the XLR outputs and is powered from the same receptacle, even if you have to run an extension cord to it. This is a bi-amped speaker so there are independent amps for high and lows. With nothing out and known good in there is very little electronics before the signal is split to the separate amps. At line level, your volume control should probably be about 2 o'clock with the EQ's straight up flat.

Please check the below mentioned things :
Verify the AC power cord is plugged into the wall outlet. Turn the VOLUME knob on the right speaker until you hear a click sound. An LED will light next to the knob when the power is ON. Turn the VOLUME knob clockwise to raise the volume. Check volume level on the computer sound card or alternate audio source device, and set at mid-level. Check plug connections on the audio source. Make sure the signal cables are inserted firmly into the correct jacks. Make sure the 3.5mm stereo cable is connected and fully inserted into the "line-out," "audio-out," or the headphone jack of the audio source. Test the speakers on another audio device. Remove the 3.5mm stereo cable from the audio source device and connect it to "line-out," "audio-out," or the headphone jack of another audio source.
And if in in case u r unable to get it working ..
Replace the speakers ..

@ Radioshack PN 271-0002 Volume Control with Push Switch, it will fix the speakers but make them MONO, so you need 2 of them to make it stereo. I recommend 2 cause this speakers have the volume distribution problem from factory.

The one cord will be connected to the computer or any audio output device. The speakers will be connected together through a cord.

Sorry I don't have a solution, but the speakers have done the same with us. Power comes on, some sound like the wire shorting out, but otherwise no sound. Tried different connection wires, different computers (mac and pc) but no go on any of them. So, I also don't think it has anything to do with you deleting some files.
