Sound and Vision Magazine put Anthem's ARC-1 Room Correction System to test and liked it pretty well. It was evaluated in combination with the top o' the line Statement D2 processor, so the bar set by the associated gear was pretty high. Setup of the $399 add-on -- gratis if you've got a D2 -- sounds pretty straightforward: connect a PC running the ARC-1 software to the Anthem processor via RS-232 and use the included mic to gather some tone sweeps. From there, bumps and wrinkles in your in-room frequency response curve are smoothed out and multichannel levels, crossovers and delays are all set up. The correction (and the rest of the D2's performance) got a solid endorsement from the audiophiles at S&V: they liked it enough to leave it engaged at all times for both music and movie performances.
