looking for a speaker switching box (?)

[dmoss74]

hi.

my current setup is a 5.1 audio through a yamaha avr. what i'd like to do is add a wiim amp for audio only (2.1).

i know there are speaker selector/switching units, but i don't have any reference to them. can someone recommend a reasonably priced unit for my needs? i'll be using the same sub and front mains with the wiim amp.

thanks

There is this one, just tested. It even gives you a remote and nice VU-meters.

thanks!

The test is just for the meter part though, not the switching. Some speaker switches treat the -ve terminals as common which is fine if the amps aren't bridged but a problem if they are. A lot of the recent Class D amps are bridged - I _think_ this probably includes the Wiim. The bridged ones require the -ve terminals to be switched too, not just the +ve ones. In either case it's safest to do the switching with both amps turned off.

If the -ve terminals are not separated, then such a switcher should not be used with most class D amplifiers.

The advert for these says "All channels adopt fully isolation design, each channel's GND is independent without mutual interference. Supports all kinds of amplifier such as BTL / class A / class B / class D digital amplifier / tube amplifier etc."

- so should be okay.
