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
cancellation.
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.
