Does What It's Supposed To Do

Rated 4 out of 5

I got this to distribute a mono signal from a mixer to numerous devices that needed the same basic signal, but at different volume levels. It accomplishes that task with no real problems. There are two minor quibbles: 1) It seems to be more prone to EMI than some other devices, and I had to be careful to separate it from some problem EMI sources. 2) Unity gain was very close to the 0 side of the volume knobs and the pots used had somewhat of a shelf from -inf gain to the first usable setting. I would have preferred it was less touchy in the -inf to 0 gain range range. Overall, it got the job done for a reasonable price made in the US with a schematic in the manual. Can't really complain.

I used for a first time during E3 2018, the fact that we could use one unit for 2 X 4 Players really help our audio distribution.
