Philips volume control

[caretaker]

I have a 2 year old Philips music CD player, you can connect it to a USB port on your computer, has 5 CD draws, radio, in all it is a nice machine but the volume control works backwards, as you turn it up the figures go down like 28 db and the if you turn it down they go up like 57db.
This dose not affect the sound control or the volume coming out.
Is it an easy job to rectify ?
I can live with this as I have had it 2 years but it was on a sale so did not complain.
The model is MC M570 MICRO SYSTEM if that helps.

It make be like my technics system which displays in -db, 0db being the highest volume and -80db the lowest.

Does it go to 11?

Somebody correct me if I am wrong but I think these type of rotary control consist of an optical rotary encoder with quadrature output for directional sensing. However I have never had one apart so can't give any advise on repair.

It is I suspect a fairly common failure mode for hi fi systems. I imagine in this market segment every component is specced down to a price hence reliability suffers.

cheers,

Ike

It go's from 76db to 1db, at 1 it blast my eardrums.
After 76db it says vol mute.
Sounds like Jeff is correct, thanks for that.
