Yup. The matchmaker goes between the PC's consumer-level balanced 
connections and the Gentner's pro-level balanced connections.

We've had very good luck with the Genelecs, which is why we're recommending 
them. There are indeed open mics -  that's why we use the Gentner for echo 

The genelecs work great in large rooms - we used a pair of them at a 
temporary AG node installation in a large hotel ballroom and had more than 
enough sound available.

We've got some of the Crown PZMs, and found them unusable in our building 
as they picked up too much -- HVAC noise, building rumbles, fan noise, etc.
