[slinkelist] Re: Sony DE135's (was: Re: DXS pricing And other issues)

[Dave Kolb]

How right you were - I wish I knew more about electronics. I wish others did
too!. I asked about this to the sales folks and they of course said no
problem. I thought I was going to get 4 channels not 2 in series.

Indeed when I attached both sets of speakers to the receiver, the volume
control or on/off in either room would affect the other room. Also if I turn
either A or B off at the receiver, the other set gets notieably louder.

I'm going to reconsider what I'm doing.

Thanks,
Dave
