48 is not Holly grail for any video production , you can record 44.1 and convert the audio to 48 .
there still allot of sfx librerias who use 44.1 and convert it to 48 in editing , for voice recording there is no much difference between 44.1 and 48 . in 90s when most of the editing was made on avid which could only support 44.1 that was the main recording . the 48 become popular only after dv cams came to the market .
the main problem i see to use it in normal way is no tc channel so you need to record it on one of the tracks what might bleed to other channels and i dont see any pfl to check individual channels what quit crucial if you do mix your stuff and need to check the inputs .
phantom power on 2 channels is also not abig problem as these who will use that one probably will go to proper preamp first and then line level , all the wireless gear ( at least professional grade ) have line out capabilities not to go tru zoom preamp .
so its allot for 400 and make sense for any mixer have one at least as spare board .
