Here's What The MX399 'SoundPro' Microphone Multiplexer Delivers:
	Provides a single, spatially-averaged acoustic input from up to four microphone positions for Real Time Analyzer measurements
	Provides a continuously-updated average measurement of the overall response of the listening area to allow easy equalization adjustments and average response documentation
	Avoids the problem of making room adjustments based on the acoustic response of just a single point in the room, or of manually averaging measurements to determine needed adjustments
	Performs four microphone multiplexed sampling, as used by all major cinema/sound reinforcement/home theater organizations, for a good average of overall room response
	Measures the averaged output of two, three, or four attached XLR microphones, or monitors individual microphones for gain equalization
	Provides internal microphone supply voltages and preamps to eliminate the need for extra boxes and simplify setup
	The MX299 is the perfect companion to the SoundPro to help test, adjust, and document the acoustically averaged frequency response and sound pressure level of cinema theaters, home theaters, churches, halls, banquet and/or meeting rooms
	Portable, battery-operated design eliminates the need for AC power connections
	Unit power automatically controlled by connection to an SP395 or SP495 'SoundPro'
