Should also note that it isn't that you need a 'Matchmaker' specifically - you need to have some sort of balanced / unbalanced converter system in place. Talk with your local A/V supplier company - they may have a cheaper solution.
As an aside, for the line out connection, I've used the Extron ASA101 (now I think it's been superseded by the ASA141) which will take stereo unbalanced (line out of the computer) and convert it to mono balanced (ClearOne Input) directly.
