Sennheiser ASP212 vs Shure UA221

[Hal Harrison]

Hello All,

Putting together a wireless rig for a church and they are wanting several dual systems (single rack mount) and wanted to combine the antennas from a pair of systems. I have done this many times with Shure (SLX, ULX) and have used the UA221 kit which is pretty cheap. I was looking to see if Sennhesier had something similar and indeed they do (ASP212) but is it almost 2.5X the cost of the UA221. From reading the specs, the 2 splitters look to be essentially the same thing so I was curious if I was missing something as to why I couldn't use a UA221 to split 2 Sennhesier ew100 systems. Both the UA221 and ASP212 are wide band so frequency range shouldn't be an issue. Anybody use the UA221 with Sennhesier stuff?

Thanks
Hal

RF is brand agnostic. Frequency range compatibility is the primary concern.

That's what I thought Henry but I wanted to make sure. I didnt know if it had some type of special voodoo since it was 2.5X more expensive than the Shure counterpart.

Thanks

The Voodoo you are thinking of is called "branding"

Does the ZSC pass DC for line amps? Will it tolerate DC on port 1 and 2 ?

No and no. You'll need DC blocks.

Fun fact....

QUESTION:
How can I tell which UA221 leg passes DC?
ANSWER:
One side of the UA221 splitter is marked with a Shure logo, arrows, "ANT", "R1", and "R2".

The R1 - ANT path passes DC.

The R2 - ANT path blocks DC, as does the R1 - R2 path.

I thought so.
AFAIK the Sennheiser G3 series does not have DC on the antenna inputs, only the ASP 1 splitter, and 2000+ series does.
