How do I activate speakers on Clavinova CVP 601 piano after having disconnected the head phones


It is likely the contacts on the headphone jack are sticking. If you're lucky, spraying some contact cleaner into the input will loosen it. Be careful not to get the spray onto the rest of the cabinet o the keys. If that doesn't work, you will need to take the unit apart so you cab get to the part to clean it.

Buzz coming from elec. guitar pickups only when using Aviom and headphones


It is a definite pickup grounding issue causing hum/"buzz" which diminishes when touching strings. Check the impedance of cable jack inputs and cable which should be 1/4"mono input/output jacks) . A personal preference but effective is to NOT run guitar direct into mixer but through an external amp w/ a headphone out jack . Noise gating/preamp filter also will help eliminate the "buzz"/noise from pickups. It is unfortunately the nature of the "electro-magnetic" beast when it comes to electric guitar pickups .Hope this helps.

My frontman 15r has power but no sound


Check to make sure the problem is not with the headphone jack or the external speaker jack as these are in the circuit between the power amp chip and the built in speaker.

You can also trace through the circuit with a music source on the amp input and with simple headphones check the signal path through the circuit until the music disappears. To do this, take a headphone and set it up with 2 test leads on the ends- attach one to ground.

Now your TL072 op amps have 2 outputs, pin1 and pin 7. The inputs for pin 1 are pins 2 and 3, and the inputs for the amp section outputing on pin 7 are pin 5 and pin 6. If you get sound at pin 1 or pin 7, you move forward to the next TL072. Check for output. Then move to the power amp chip on the heat sink. Pin 1 should be the output and will be wired to the headphone jack first. The external speaker jack second and the built in speaker third. The input for that power amplifier chip is pin 7 or pin 8 depending how it is wired.

If the amp chip is blown, make sure to put an adequate amount of thermal grease on the back side of the IC in contact with the heat sink so it can operate as cool as possible.

Yamaha CP 300 broken headphone jack


Some keyboards use the amp output sockets for headphone use.
You might need some adapters for your headphones.
If it fell in, you would see an empty hole. This would be unlikely because it is held on by two screws. If all fails, buy an amp with a headphone jack input. Plug the keyboard into the amp and use the amps jack.

Behringer ub802 mixer is buzzing even when no input when i hook my head phones into the headphone jack and main output jack


If it buzzes when you have no inputs AND no output leads connected, there is a problem with the power supply... HOWEVER if you have used UNBALANCED output cables instead of the REQUIRED TRS BALANCED output cables, it is possible the noise is being driven backwards and that is what you are hearing. Note that at full gains, there often is a tiny bit of noise, usually hiss. Also make sure the supply is powered from the SAME receptacle as the equipment this drives such as an amp or powered speakers.

I have a MG50DFX and a MG15DFX, both amps head phone inputs don't work anymore. When plug in the headphone the speaker won't silence.


This is likely a bad switch contact in the headphone jack... they are really poor quality in most amps... plastic case and EASILY damaged by side forces on the jack. REplacement is the solution.

My line 6 spider iii30 30 watt amp works with


There is likely a switch contact on the headphone jack that routes the amp output to the speaker. These jacks on most music stuff are JUNK and the contact may not be closing.

If the spring contact is bent so it won't close you can bend it to contact BUT the springyness usually is gone and the contact will be marginal.

Marshall MG100HDFX 100-Watt Amplifier Head. The head phone jack works but speaker output is dead. Hooked it to speakers with another amp input and after word it stopped working. Can't see any overheated...


You'll have to take it in to get it repaired. From what you described it sounds like you blew the output stage out. You can't run from your speaker output jack into the input jack of another amp. You should go out of the recording out, line out, effects out or in the least case your headphone out. What happens usually is your output transformer short circuits due to a mismatch of impedances. It sounds like you still have a transformer though so you might have gotten lucky. You will need to take it in though. Sorry.

I have a 20 watt peavey micro bass, and what happened was my brother knocked it over and will not turn on. I checked the fuse and it was ok, any help you would be great.


When it was knocked over it may have cracked the main circuit board, but does the pilot light come on at all? If the pilot light comes on but no sound is output from the speaker try plugging some headphones into the head phone jack and then turn it on and see if you can hear sound in the headphones. I have had a similar problem before and the main speaker had gone bad but it would still play thru the head phone jack.
