Question about Audio Players & Recorders
I need some help please....
I have a 5.1 Hi-fi amp, when I turn it on (power) the volume increases and does not stop at a particular level - it just keeps climbing - I turn it lower via the remote, it does go lower - but then just climbs to maximum again... do you have any ideas for me please in terms of how best I can fix this?
Thanks a mill
I'd love to have more information to go on, but I can give you a few things to check:
If there is a traditional volume control that is motorized, you will see the volume knob start moving on its own after you start it up. If that is the case, you'll need to have someone look at the motor control circuit. Luckily these are almost so generic that parts would be as common as replacing fuses.
If there is a volume knob that is an encoder, it may be faulty. How to tell if it is an encoder? Easy. If it will spin continuously with no extra effort, in both directions, it is an encoder. If in fact there is an encoder present underneath the knob, and the amp is responding to the remote correctly, it may be as simple as someone replacing the encoder.
If there is no volume knob at all, just a couple buttons to press, one for up, one for down, there are issues in that circuit that will need to be addressed.
If the volume control is only from the remote, and it keeps climbing on its own until you turn it down, there is a digital volume control chip that controls the volume. Unfortunately, anything in the circuit from that chip itself, all the way back to the sensor for the remote, could be faulty.
HOWEVER, do not despair yet, there may be another area to check. Turn the amp on, then IMMEDIATELY take the batteries out of the remote. If the volume stops climbing right there and then, guess what? :) Time for a new remote, or have someone take a look at the one you have if it is an expensive unit. One more related thing to check: If there are any other remotes in the room, remove them, or any other possible sources of infrared light. Alternately, take a piece of heavy black electrical tape and cover the sensor for the remote, and turn the amp on. If it behaves normally, something else in the room is "telling" the amp to increase volume. If any of these tests produce results no different from what you've experienced so far, the fault is in fact inside the amp.
