If the noise appears only when you rotate the control, there is dust inside it. With the amp disconnected from mains, rotate the volume control from min to max back and forth for about 30 times. See if this helps. This is not a definite solution, you maybe have to replace the potentiometer or spray some potentiometer cleaner. Good luck!

Pyle PPHP159WMU: Just received this used unit and the bass speaker tends to cut out the louder the volume is set. Does the battery have to be fully charged for the unit to function properly?


The speaker may have a current sensing device to avoid damage under high volume conditions. Also check the setting of your bass control. Every 3 db increase in setting doubles the power going to the driver and it is easy to over drive the unit at high volumes if your bass control is not on flat.

some amps are made more for low ohm loads (bass) and some are made for high impedence loads (mids/highs) and it seems you are asking too much from your amp.

Maybe the capacitor in the power supply burned upon unplugging the heater. The power supply is a coil with iron core, next to it, there should be a rectifier and a capacitor. If the capacitor is burnt, the powersupply will still be working, but there will be noise on the line, the 50 Hz that comes out of your wall outlet. Capacitor of the same value can be bought for small change but has to be soldered in.

I need to turn up the bass on my denon amp


A few ways to get more bass here you go John.

If you have a sub check your level and crossover settings on sub and on amp, on the sub half volume and 90-120 crossover should be kicking,

Run a speaker level test on your denon and turn up sub channel.

if you want more bass in your speakers press the tone button on the front panal. for some i believe its in the menu system under parameter

Depending on what the source is you can turn up the bass on the source. aka ipod, some dvd players and what have you.

My Behringer gx212 ultratwin amplifier started to lose volume last night at band practice and then I smelled buring wiring. I think I lost or am in the process of losing the amp transformer. I think the...


Hi I just recently purchased a Behringer GMX 212 and had similar volume dropout on the clean channel only Channel 2 works better and has more punch in clean mode.I went to the shop where I purchased it with a 7 day warranty from some indian dude here in Nadi Fiji, and there was another GMX 212on the floor so I decided to try it out. This was a new amp. I plugged into the clean channel and turned it up full volume on guitar and amp adn heard the volume drop of in the amp in almost a curve and then the whole amp just cut out. We unplugged and waited, turned the amp off, and then on and stil no sound. We then tried the guitar and cord in another amp. The other amp was fine. Can you solve this problem.......my gut feeling is this happens a lot to Behringer amps.

Control the volume on each of the 12 bass shakers i plan to install


Please note that you can't simply wire them together in series or parallel. Connecting any more than 2 would likely cause damage to your amplifier. (depending on the impedance of the bass shaker 4 ohms, 8 ohms, etc.)

The Buttkicker brand recommends the following configuration for four buttkickers into one amp: Click here

As you can see, you need a combination of parallel and series connections to make sure the amp is "seeing" the correct load. I'd recommend purchasing three dedicated subwoofer amps (there are some good inexpensive ones at http://www.parts-express.com.

This will give you volume control over each set of four shakers at the amp itself. If you need control at each shaker, the only solution I know if is to use an impedance matching volume control.

Check Parts Express for those, too.

If this solved your problem, please rate it as FixYa. If not, let me know how else I can help you.

Good luck!

Digital surround mode not putting out bass-RX-6022V


On the unit, just left of the volume control there a "adjust setting", cycle through the modes until you SUBWOOFFER and then press CONTROL UP or DOWN to make it say YES. I have no idea how it switched to NO. Probably with my remote, but some time did pass and I'm happy I got my Bass back. Quantum of Solace sounds great.
