I used this product to mix acoustic guitars and vocals for small to medium-sized performance venues. The value added is for people with limited expertise in adjusting settings for different inputs. Bose created preset options for popular equipment based on the manufacturer's recommended settings for each product. If you are uncertain how to adjust the settings for a Shure Beta 57A, just select that option in the Bose menu and the Tonematch will automatically adjust the settings to match Shure's recommended settings for that specific microphone. Bose has provided these presets for a multitude of instruments and equipment. The system allows fine-tuning those settings and or adding numerous effects to suit your individual taste or the Tonematch presets can be ignored altogether for more sophisticated users, who know how to achieve their signature sound. I had never used a mixer and I was able to find the correct presets and set up the entire system for show-quality sound within minutes. I never even read the instructions. For a pro-audio novice with demanding standards for quality, I cannot imagine a quicker or easier route to performance quality sound. Thank you, Bose and Sam Ash.
