The LM2B is the "up converter", amplifying unbalanced IHF signals 14dB and providing balanced output signals. This converter uses extremely quiet, high quality active circuits with adjustable gain controls so that signal levels from various devices of gear can be matched to one another.
The Whirlwind LM2 Level Matchers are unique, high quality solutions for converting analog audio levels and impedances between -10 dBV "consumer" or "semi-pro" (also known as IHF standard) unbalanced equipment and +4 dBm balanced professional equipment.
