Mix 51 is a powerful 5.1 surround panning and mixing plug-in for Pro Tools LE and M-Powered systems with six or more outputs such as Mbox 2 Pro, 002, 003, and M-Audio interfaces. Unlimited mono Surround Panner and stereo Surround Panner plug-ins can be placed on track inserts to pan, mix, and send to the Mix 51 Surround Mixer busses. The Mix 51 Surround Mixer plug-in provides 30 channels of outputs grouped as three, 5.1 main busses and three, quad effect send busses so you can easily manage dialog, music, FX, and surround reverb send submixes. Both the Mix 51 Surround Panner and Surround Mixer feature fully automatable controls which can be migrated to Pro Tools HD systems for compatibility with world-class surround mix facilities worldwide.
