529.0. "Can you disconnect speakers?" by IOSG::CARLIN (Dick Carlin IOSG, Reading, England) Sat Jan 06 1996 14:22

    I've just bought a Rotel 930 amplifier, which I'm very pleased with.
    However I've just discovered a shortcoming compared to the original
    amplifier I had.
    
    The only switchable speaker combinations are:
    
    	position 1	Speakers A (+headphones) only
    	position 2	Speakers A (+headphones) and Speakers B
    
    Can I achieve the Speakers B only combination by simply switching the A
    speakers out? Would the amplifier mind the A output going open circuit?
    I imagined it was ok to do this since the instructions tell you to wire
    the (single pair of) speakers to the B output if you want the following
    combinations:
    
    	pos 1		Headphones only
    	pos 2		Speakers only
    
    It seems to me that this would result in the A output being open
    circuit with the switch in position 2, therefore ok.

Dick,

If the instructions say you should set up with no connections to the Speaker A
outputs to get the configuration you want, then I woudl expect that the amp is
constructed to do just that. You could check with the dealer and/or the
importers for a more authoritative response.

The reason I dont like to see open circuits on the speaker sockets dates back to
valve amps and the possibility of blowing output transformers.

Regards

Dave
