Precision level controller with stereo fold-down capabilities, the Coleman Audio SR7.1MK II ensures that all audiences are able to enjoy your 7.1 surround mixes on any system. This rackmount 1U controller has recessed level controls for each of your eight inputs to tailor your speakers and sub to your listening environment. Once levels are set, a 47-position stepped master control with a 0.05dB tolerance lets you adjust all inputs consistently from that point forward. Four front fold-down switches let you test your mixes for mono, stereo, or 5.1 compatibility to accommodate TV speakers to mobile audio to last- and next-gen surround systems. A 5.1 version is also available.
