I bought 4 of them to my recording studio, to use them as independent phones amplifiers for musicians - 4 diferent mixes to 4 differend spots. They do the job greatly and work better than classic multichannel phones amps, because every musician have it separetly and also everyne can do some small changes for themself (eq or levels if there are more than one signal routed to the t.mix). Also the price is great, I paid less for 4 small mixers than for one decent multichannel phone amp. It can also be usefull for live sound, eg. in-ear monitoring for a drummer or a keyboard player.
A BIG YES from me.
