Excellent Chris - that'd make sense and worth a check. Thanks.

Rob



Can you just go and check the lettering again?

It might say BTL and not BLT, in which case it would stand for 'Bridge
Tied Load'.

Bugger - sorry! BTL it is. Thanks Chris. It's just food food food with me.
I've jut googled it and it seems to mean a form of bridging -correct?!

Rob



Yep, it will switch one of the inputs to both power-amps, but phase
invert the signal to one. You take the speaker output between the 'hot'
speaker output sockets.

As someone else said, bridging gives twice the voltage swing, and
therefore theoretically four times the power into the same impedance
load, but it's not usually that simple, as the voltage and current will
need to double, so the amp usually runs out of current well before it
manages to give 4 x the power.
