Question about Audio Players & Recorders

1 Answer

Volume control is too loud at minimum settings.


Would a resistor added between the wiper and ground make the lower volume settings lower? If so, what value would be a good starting point?

Otherwise, an attennuator between the wiper and power amp section would reduce the overall volume but, what is the input impedance to the power amp stage to calculate the resistor values?

Or, would the cleanest solution be to reduce the overall gain in the power amp stage somehow?

Minimum volume way to high

There may be a low/high switch which lowers or raises the base sound level before the volume control has any effect.

How fix talkback in magnum delta force

you need to check the audio path from the chatback board to the audio circuit

usually the audio out the board will go to the center connection
on the volume control
sometimes people use a resistor to attenumate it to a level
or a T pad
and connect it to the left side {audio out to amp}
so a volume control works like this

left center right
ground audio into control audio to amp

so usually the center is used as the volume will track up as your sets volume is increased

so simply connect the audio out from the chatback
to the right audio to amp section

on the chatbacks ive made and installed in the past
had a small pot on the board
this allows the volume from it too be increased

so look for this first

if you cant find it you can make one up like this

100K log pot 3 pin

1 2 3
L M R {left middle right}

1= ground
2= audio from chatback
3= audio to the right right audio to amp on the cb's volume control

then no matter what level the actual audio from the set is set too
the chatback can be set to a standard level for all

hope this helps you

i used too build chatbacks for the rnid year back and fit them free

The volume on my Denon dra-555 amplifier goes up and down. Any idea why

Your resistors at the volume control are either going bad or you need to replace the volume control its self.

Just realized your not insignia and want money, ********

A) This is not Insignia.
This is a Product Support website.

B) This recent post of yours is in the Free section, and looking back at your problem you posted, it is in the Free section also.

C) The website does have a Premium section where problems are charged a fee.
You're not in that section.

Shall we go on, and delve with your volume control on your sub-woofer?

The Volume Control on your sub-woofer is a Potentiometer. A variable resistor in this case.

Observe the top photo, then go to the illustration below it.
(You can click on the photos/illustrations, and enlarge them. You can enlarge twice)

The construction of a Potentiometer varies in it's usage, and by the manufacturer.
(I doubt Insignia makes their volume controls. They buy from a manufacturer that does)

Your volume control won't look like the second illustration down, but it gives an illustration to show you to help explain the following;

See the triangular shaped piece that extends from the shaft in the middle? Number 3
This is the Wiper Arm.
Note the round shape that the Wiper Arm will slide against. The circular outside portion.

The circular outside portion is a Resistor. There is a contact on one end of the circular shape, and a contact on the other end of the circular shape. (Or a contact on either end of the Resistor)

With the Wiper Arm at one side of the Resistor, no volume is allowed out. As the Wiper Arm is slid across the Resistor, more volume is allowed to come out. When the Wiper Arm is at the other end of the Resistor, there is no resistance, and you have full volume.

With a volume control you are not turning the volume up.
The volume is already at full blast. When you turn the volume control you are allowing more of the volume.

It could be compared to having a garden hose in your hand, the water is already on full blast, and you have the hose pinched off with your fingers.
The more you let go of the hose, the more water comes out.

The popping sound you hear is a dirty contact between the Wiper Arm, and the Resistor. A few spots on the Resistors surface, actually.
OR, there is a worn off surface on the contact end of the Wiper Arm.

Would mean the volume control would have to be accessed.

For dirty contacts:
You could try removing the volume control KNOB, and using the plastic straw provided, use an electronic cleaner. (Spray can)
Squirt the cleaner down in the volume control, then turn the shaft back, and forth.

If this doesn't do it then the volume control would have to be replaced.

Very little volume, not very loud at highest

On the TV-use your finger to adjust the volume level, about midway, then use the remote to shut off the tv, then turn on tv with remote. Volume level should be better! If still not loud enough...using your finger on the tv...turn up volume & repeat remote steps.

The minimum volume setting is too loud for my ears. Is there anyway to gain a lower volume setting?

There are a couple of different ways to lower the volume. One is to check your settings to see if you have a volume limit setting and turn it on. Another way, check the settings and see if you have a equalizer setting, and see if it is turned on, then experiment with other settings. If you have a built in 4 band equalizer you can set the sliders all the way to the bottom and it should turn down the volume a good bit. Last, is to go and by cheep ear buds / head phones, the cheeper ones, take more volume / power to get loud.

the new ringer volume and the volume bar will be increased or
decreased each time the setting is adjusted At the lowest setting
the ringer will be turned off and the display will show:

• With the handset or base in idle (off) mode, press or of the
volume control will directly go to ringer volume menu

Fluctuation in sound output on Cambridge Soundworks 5.1 speakers

Hi Paulus
A lot brand of speakers, like Sound Blasters, Logitech, Cambridge, has this (strange) kind of volume problem, sometimes, is the resistor, in the volume control, sometimes in the modulator for the board on the sound speakers, Subwofer.
I use a general tip is let the volume in one setting and don't move in the intermediate low volume say....9 .
from other thing, be change the speakers.
