hi-fi amp problem
just moved house, set up the hifi, and got a bit of a strange problem that i cant suss.
cables go to both speakers (they have red and black sockets, one set on top of the other.)
amp has SP1 and SP2 which i assume are the two sets of sockets on the back of the speakers. cable plugs go into the top set, as they were in the last house. they havent been disconnected from the amp during the move, so thats not the problem either.
whats happening is….. the sound only comes out of both speakers if ‘mono’ is selected on the amp. if i select ‘stereo’ then it only comes out of one speaker.
obviously the fact that sound does come out of the second speaker in mono means its connected ok, the speaker isnt knackered etc etc.
any ideas? has something been damaged in transit?

Are you getting this with all the inputs? If you’re getting sound through both speakers on mono then maybe theres a bad connection between the CD player (or whatever) thats going into the amp. If you’ve only got one thing attached maybe run that through a different input and with a different lead.Posted 4 years agostumpy01Member

Apologies if stating the obvious but are the speakers plugged into L & R channels rather than one in SP1 and other in SP2
Some amps have outputs for 2 sets of speakers, which you can then often select between with a switch. They are normally labelled 1 & 2, while the left & right speaker channels will be labelled L & R. Sounds like you’ve got one speaker wired to one set of speaker outputs and the other speaker wired to the other output.
But you say it worked like this before? is there a speaker button to switch between SP1 & SP2. I am guessing that it has been pushed and previously it was set to both, whereas now it’s only set to one of them.
I’ve found the manual online….
looks like you have two buttons on the front. SP1 & SP2. You probably only have one of those pressed.Posted 4 years ago
You should probably have both speakers though connected only to SP1 or SP2, rather than one to SP1 and one to SP2…..
thanks chaps. just had another look at the back. both sets of red/white plugs go to the top red/white sockets in the back of a pair of mordaunt short speakers.
id have guessed thatd be SP1, but im wrong. SP2 is selected. if i select SP1, no sound whatsoever, either mono or stereo. only SP2 will play music, and as i say, its only mono thatll give sound through both speakers. same if both are pressed.
no cd, tuner or anything, all ive got plugged in is a squeezebox touch 🙂

just started moving the amp about to change the squeezebox connection to a different input to try. as i moved it, the second speaker kicked in 🙂
so…… looks like its a loose connection somewhere. not sure where, but if it drops again, ill just wiggle everything about.
thanks a lot gents 🙂Posted 4 years agojambourgieMember
I’ve had this problem on my amp for ages. It’s not Arcam though, (Harman Kardon). It’s an intermittent problem so I’ve never bothered to look at it (Also, last time I fixed an amp I got massively zapped by a capacitor). I find that when the left channel cuts out, a good hefty quick boost of the volume brings it back in. Almost like it needs the force to clear a blockage or something 🙂Posted 4 years agoBigButSlimmerBlokeMember
any suggestions for a decent amp for someone with not much wedge
You might want to consider the ageing but otherwise excellent Kenwood KA3020, which, by strange coincidence I happen to have a spare one of.Posted 4 years ago

BBSB, looks like my amps got a stay of execution for now 🙂
thanks for the offer, i did have a quick google of it, and it does seem to be a good quality old amp, bit like mine 🙂Posted 4 years ago
