Speaker Selectors |
|
|
Does anyone have any experience with speaker selectors. I am trying t
add additional speakers (a total of 8) to the "A & B" terminals.
have an older Onkyo TX-SV525R surround sound. I know how a speake
selector works; however, I'm concerned that it may damage m
Tuner/Amplifier. Is there a preferred model or manufacture? I wa
looking at the Radio Shack brand. Any advice would be greatl
appreciated.

Ron,
There are speaker selectors that have 'protection circuits' built in,
which are usually resistors so that the impedence does not drop too low
for the amp. However, this approach wastes amp power, and does not help
sound quality. (Adcom makes some, or used to.)
Connecting 4 pairs of speakers is likely to damage you receiver at any
listening levels above very soft background music, the amp simply is not
designed for it. The failure is likely to be catastrophic - sound one
minute, dead the next. You are better off connecting 2 pairs to the
Onkyo, and connecting an integrated amp (or receiver) to the record outs
of the Onkyo, and using that to drive the additional pairs of speakers.
You should be able to get something rather nice used on e-bay (or
equivalent) for under $100.

Tim,
Your reply interests me because I have two pairs of speakers connected
to a stereo amp and use a simple selector switch to switch pairs, but
sometimes I drive all 4 speakers at the same time.
Is this not a good idea? I've had it set up like this for more than a
year - no problems so far.

Rosco,
Do you mean that you have 2 speakers on each channel, or 4 speakers on
each channel?
If the former, and the speakers are 8 ohms, then you are not likely to
have any problem, especially if the amp is rated to accept 4 ohm
speakers. If you've got 4 speakers on EACH channel, (8 speakers in
total) then you may be asking for trouble, unless this is a PA amp rated
for 1 or 2 ohm loads. Again, your listening habits will have an
effect. If the amp is not running hot, and its survived what ever
levels you listen to for a year, then you are probably OK.
The gentlemen I replied to yesterday wanted to run 4 PAIRS of speakers
on his amp.

Tim,
Thanks for the info - I have 2 speakers on each channel, and I don't
often play them all at the same time, so I guess I'm OK.
