Mini as source for two zone amps?

[mvalburg]

Will the aux output on a Mini act (with splitter) as source for two separate (stereo) zone integrated amps that are physically in the same place?

It will sort of work but does one of the amps have a tape out? If so you might be better off connecting the Mini to one amp and using its tape out to connect to the other.

Thanks for responding. Could you expand a bit on "sort of work?" What are the limitations? (No tape out on the amps).

First, you need a suitable splitter, of course. The WiiM Mini has a 3.5 mm TRRS jack, no RCA outputs, so you need something that gets you from 3.5 mm to two stereo pairs of RCA plugs. This is rarely found in a single cable. You'll probably need to connect multiple cables, which is not ideal.

The input impedance seen by the Mini's output with two amplifiers connected in parallel will be lower (roughly halfed, if both amps have the same input impedance). The result is that the Mini's output has a harder job driving both amps than it has driving only one. The capacitance of the cable will have a bigger influence, so highs can end up to be attenuated. You would want the cables to be as short and direct as possible. This could conflict with the need for multiple cables mentioned above.
