This came as part of a promo offer that Thomman packed together with the StudioLive 32R Mixer. It's not something I had in mind using, but given the limited immediate controls on a rack mixer, it has evolved into a very high quality, feature packed monitor controller in my studio. I've routed the StudioLive 32R master out to come out of the 15-16 channel of the Earmix 16M. They are connected vía AVB cable and from the earwax onto my monitors. I've. also routed my mix buses onto different outputs on the Earmix, which allows me to mute or solo each bus as necessary. It enables an independent line out to the monitors, a separate phone jack and the possibility of adding an external audio source (4mm stereo jack out from a phone, laptop) so it can be heard through the speakers. For example... if someone brings a demo they want me to listen I just plug the phone output into the earmix, and now I can hear it on fantastic sounding speakers on whim.
It's so versatile it could be used in various other alternate scenarios. Works and especially sounds great. And no doubt having a monitor control is essential for me. This one substituted my previous unit (ESI MoCo). Huge win!!!!
