Foreward Dear Customer, Thank you very much for expressing your confidence in SM Pro Audio products by purchasing this unit. The M-Patch 4M was designed to be a comprehensive studio monitor controller for home, project and professional studios, sound equipment rental companies, repair centers, schools and fixed installations— in short, virtually any and all venues where audio products are used.
Multiple switches provide for mute, source selection, output assignment, and stereo/ mono operation. A built-in talkback microphone, which automatically ducks the Control Room outputs -20dB when engaged, an on-board headphone amplifier, and configurable desktop or rackmount operation, make the M-Patch 4M an ideal centerpiece for monitor control in home, professional, and project studio applications.
