The Brothers Four, an American folk singing group known for their hit songs Greenfields, Seven Daffodils and Green Leaves of Summer are touring in Japan with an Adamson Metrix loudspeaker system.

The Metrix sound system, provided by OTA Audio of Japan, will be utilized extensively during the 20 city tour. OTA Audio was tasked with designing a system flexible enough to handle different sized venues. The versatility of the Metrix enclosures easily accommodate everything from smaller, intimate club settings to larger performance halls on the schedule.

“My original perception of the Metrix system was that it is was designed for rock and roll, not necessarily acoustic groups,” explains Mr. Ota, managing director of OTA Audio. “But I have found that it provides a high performance acoustic sound. The band sounds pure and unprocessed.”

The Brothers Four is on the road with twelve Metrix enclosures that are typically ground stacked, six per side, to the left and right of the stage. Four Metrix subwoofers – two per side, stacked below the Metrix enclosures – provide low end support. The system is powered by four Powersoft K3 DSP+AESOP.

The tour kicked off with two performances at Yomiuri Otemachi Hall which were both sold out.

“With an acoustic act you want to reinforce the instruments and vocals while keeping the sound natural,” adds Mr. Ota. “The Metrix system did that perfectly. We can easily pick up the sensitive nuances during the mix to reinforce the act. The audience and band are quite delighted with the Metrix system.”
