Question about Panasonic SC-PM28 CD Shelf System

Open Question

No sound! Since getting my Panasonic SCPM28 out of storage after 6 months, the volume level will not go above 0 decibels (i.e. complete silence!). I'm sure the speakers are wired correctly ...

- 82k  ^  0k  is normal   it is called consumer output. when you go into the + zone   that is studio grade pro audio.  so this is not your problem... i think  either you have a bad output or bad speakers...... try some other speakers,but careful !  not to blow them with loud volume  if they are not set up for this unit.  hope i could help   also try other on board sound settings when trying other speakers       imanfix

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

Why is the volume on my JVC KD-SR80BT limited to 30?


The number on the panel of your car stereo is not a measure of actual volume. It is just a comparative scale, with 0 being the minimum and 30 being the maximum. The volume as measured in decibels is dependent on the power level of the amplifier and impedance of the speakers. The internal amplifier puts out 22 watts per channel (50 watts peak) into 4 channels, and there are output jacks for an external amplifier(s). Product specs in link.

How do i turn my sound up


The Windows operating system on your Toshiba laptop contains a functionality that allows you to increase the volume.


Your laptop's volume is a measure of the decibel levels of sound that your Toshiba laptop will put out.


If you are having trouble hearing music of video files, you may need to boost the sound volume, which can be accomplished by following several steps.


Press the "Start" button on your desktop.


Click on the "Control Panel" icon then double-click on the icon labeled "Sounds and Audio Devices."

Click on the "Volume" tab then move the device volume slider to increase the volume.


Close the "Control Panel" when you have completed the operation, and your volume should be louder.


Hope this helps.

How to express a loss as a gain in dB?


Decibel is what sound is rated in.

The sound level is expressed as a line.

0 in the middle.
Negative values are to the left, Positive values to the right.

Less DB rating to the Left, more DB to the Right.

Anything above the 0 is louder. 1, 2, 3, 4, 5, 6, etc.
Anything below the 0 is not as loud, -1, -2, -3, -4, -5, -6, etc.

It would be correct to state a 6 DB loss as -6DB.

I have a 2001 chrysler voyager installed a kenwood stereo and when i raise the volume to where its lound the radio will turn off and on untill i lower the vol


My electronics savvy source says you may be overdriving the amplifier in your Kenwood stereo to an impedance-mismatched set of speakers, meaning that the speakers are impedance mis-matched to the Kenwood stereo, and therefore operate ok (but inefficiently) at low volume, but cut off completely at higher volume.
Fix: match the impedance of your speaker network to the specs on your Kenwood car stereo. Once this is done, you should be able to crank up the volume to the point of permanent hearing loss.
SAFETY CAUTION - sound levels above 85 decibels produce NIHL (noise-induced hearing loss).

I have a Bosch dishwasher model # shx4ap05uc/06 and I want to silence the alarm for when it is done. It goes off every 10 minutes until you open the door


Hi,

Yes, you can switch the cycle completion signal off (or raise/lower the volume)

1. Switch the dishwasher off using the ON/OFF button
2. Open the door
3. Switch the dishwasher on again. (One of the wash cycle LEDs will flash.)
4. Hold the > button in. Continue holding it and press and release the Start/Reset button once, then release the > button.

"Clean" and one other LED should now be flashing. This indicates that the dishwasher is in the options/settings mode. If they are not flashing, start over at step 1.

5. Press > repeatedly, until the LEDs for "Clean", "Sanitized" and "Rinse Agent" are all flashing.
6. Press repeatedly until none of the LEDs are flashing.

The number of flashing LEDs indicate the volume setting . . .

0 = Silent
1 = Volume level 1
2 = Volume level 2
3 = Volume level 3

7. Press the Start/Reset button once to save the setting and exit the options mode
8. Close the door
9. Switch the dishwasher off.

Hope this helps. Please let me know if you need further assistance.

Regards,
BElectric

Why do the volume numbers on old receivers start


This type of calibartion is known as a logarithmic scale.
The numbers refer to decibels below the maximum output of the amplifier section of the reciever, or decibels of attenuation (making smaller/quieter).

Without going through logarithim theorey, the logarithim (base 10) of 1 is 0. So if 1 is the maximum output of the amp, as you turn the knob down from maximum you are adding more and more attentuation to the output (relative to maximum) and so the loudness of what you hear goes down, even though the number on the scale is going up !

Most peolpe associate decibels with sound levels, but anything can be measured in decibels, so long as there is soemthing to reference it against.
