Hi There
Im new to the forum and from York, England! I dont know a huge amount about hifi as you will see from my question which is basic!
I have a Revox B-242 (B242) Power Amp which I have had for many years, and was given for free by a family friend who had a full house Revox multiroom system in the late 1980's. The thing weighs a tonne! (17kg), built to last, and priced accordingly, it was £1800 in 1988 in the UK.
Anyway my question is a basic one - HOW DO I TELL IF ITS PLAYING MY CD's in Mono? is there a simple test, or a track I can play to show left and right speaker playing different tracks etc
Really stupid question I know, because when I press the "MONO/STEREO" switch on the back, on Stereo it only plays one speaker, and on mono plays both! Only one Channel on the LED screen at the front is lighting up
Anyone know why this is? Has one channel stopped working or something, a fuse etc? It sounds nice when playing in Mono mode, with both speakers playing! I wonder if the switch has reversed somehow (dust?)!?
My System is currently Primare D20 cd player, Marantz tuner, 2x Rotel RB-850 Power amps, Rotel Pre
The Revox is the most "High End" in the system, but I need to raise some cash because of redundancy so I think it has to go, and I just dont use it much!
It was serviced by the UK Revox repairs agents Thear Technology in 1998 not long before I stopped using it, with no reported faults.
The Mono mode is called "Bridged Mono", seems to imply both channels are joined together, so maybe both speaker terminals used for BiWiring?
I have tried:-
1) Leaving it in stereo mode and changing the cables left to right only at the amp INPUT connections (leaving other ends of cables connected as-is). The sound still only comes out the same speaker.
I don't know how the amp works, but it would seem even in mono mode both channels, at least with respect to output, need to be functioning to put sound to both speakers?
2) I have tried a different Phono cable too, but no different!
3) I have also tried using the other output from my preamp (it has two, for two power amps)
Any ideas, am I being really thick!?
Kind Regards
Edward
