Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

Where to plug in powered speaker (subwoofer) on yamaha emx88s mixer? I tried monitor but it doesnt work.


To connect powered speakers and/or subwoofers follow the instructions on page 19. Connect the powered speakers from the Main L and Main R.outputs
"MAIN (STEREO) jack: The stereo (MAIN L,R) bus signal which has passed through the MAIN MASTER control and graphic equalizer."
for the subwoofers set the YAMAHA SPEAKER PROCESSING switch on/off for best sound as desribed on page 13.
To test this I would play the song Let's Go by Calvin Harris.
for best results use a matched pair of speakers and subwoofers
such as the Electro Voice Live ELX112/ELX115 to the elx118p subwoofer.

I have the SB-HW950 subwoofer and teh SC-PT950 speakers and I just purchased a Denon Receiver to replace my DVD/ receiver player. So now I have SC-PT950 speakers playing through the Denon but for some...


Yes, the old Panasonic SC-PT950 did drive the subwoofer by its own amp, such as it was.

http://www.retrevo.com/support/Panasonic-SC-PT950-Home-Theater-Systems-manual/id/2869dj183/t/2/

It's never a good idea to adapt prescribed connectors to bare speaker wire or vice versa.

Speaker Level and Line Level signals are worlds apart and equipment damage may result. Your Denon (model unknown) probably requires a POWERED SUBWOOFER, to which it would provide Line Level LFE from its Pre Out.

Read the manual where it doesn't say to convert a speaker wire to RCA.

Sound comes out of the right speaker with the z4 volume set at minimum. however the sound can be controlled by the windows volume control. When you turn up the volume on the z4 the left speaker works....


open your subwoofer because main system is inside in your subwoofer than clean it with a air blower ..
this happens when dust is inside the system....

How to hook up a computer sub to a hometheater amp


http://www.arcam.co.uk/_ugc/file/avr280e_manual.pdf

If you have the whole Z5500 package you could run the Arcam's optical- or coaxial digital audio output to the corresponding input on the Logitech.

But I'd be careful about letting BOTH the Arcam and the Logictech perform Digital Sound Processing on the sound. DSP's aren't meant to be stacked. My money says the Arcam is better in the DSP department than the Logitech.

If you have just the sub, run the Sub PRE out from the Arcam to the Sub/Center input (adapt it to 3.5 mm) on the Control Center and set the switch to "6 ch direct".

Connecting an Altec Lansing ADA995 subwoofer system to a stereo


I have this exact Altec Lansing speaker system and I'm currently just using it with my Dell computer. But, I know you don't have to install these speakers to any high powered receiver for good sound quality. The subwoofer has two separate 200 watt RMS combined amplifiers built in for it's single knob controlled dual 6.5" bass drivers and 2-way magnetically shielded satellites, which are amplified together by any source that has an analog or digital volume control. The speakers act as a preamp receiver to any volume or frequency tone level controlled audio source. These input sources can also equalize the speakers receiving input signal for bass, treble or mid-range adjustments. You only need to obtain the proper adapter to hook up all the speakers to your desired component or device. Besides a computer, for example a TV with a variable audio out function or a mp3 player will work. The adapter that i am referring to is similar to what is included with certain 5.1 Logitech brand computer and multimedia speakers specifying gaming console and TV connecting. It has all three color coded 1/8" connector inputs on one end and RCA jack outputs on the other. This can be purchased more easily online then offline at stores such as Ebay for a fairly inexpensive price. However this adapter will not decode true 5.1 surround, but instead give a 5 channel stereo effect. I guess if one was looking for an inexpensive alternative solution to purchasing traditional high end home entertainment audio equipment, the ADA 995s are one of few computer speaker models in my book that can do a decent job.

Noise comming from centre speaker of panasonic scpt560 home theatre system


check the cable 1st. If this speaker is powered, you could have a bad shield, or the power is causing a ground loop.
If the speaker is coming from an amp using speaker wire ie: 2 lead + - check the connection and make sure no fraid strands are touching each other on the rear connection.
In addition check your TV, Ap, And speaker system (if sub is powered independently) are all on the same curcuit.
a certain cause for ground looping resulting in hum.

The 'Subwoofer' output on your receiver is used to connect to a powered subwoofer with a built in amplifier. Your KLH speakers use what is called a 'passive' subwoofer, it gets its power from the receiver and then passes the higher frequencies to the left and right front speakers after taking out the low frequencies for the subwoofer. A speaker system with a passive subwoofer is good for casual listening, but a powered subwoofer is required for really hearing low frequencies and rumble in movies. The KLH speakers you have were highly rated in their time for their price. The four satellite speakers and center channel speaker have very good sound compared to the little 'midget' surround sound speakers most people buy today.

Here's how you hook them up:

- The left and right front channels from your receiver terminals should go to the terminals on the subwoofer marked 'From Amplifier'
- Your left and right front speakers are then connected to the subwoofer terminals marked 'To Speakers', they do not connect directly to your receiver.
- Your center speaker is connected to your receiver terminals marked 'Center'
- Your rear speakers are connected to your receiver terminals marked 'Surround'

That should get you up and running. If the bass isn't good enough with the passive subwoofer, you can get a decent powered subwoofer like the Velodyne VX-10 for about $150 and 'kick it up a notch'. Good luck and enjoy....
