dont get your hopes up for 4+ channels on a recorder with phantom on each channel.
For that, you're looking at the SD 788...and products in that pro-use realm. These types of decks are much more for the basement musician, which is the hotest market in music hardware like this.
this market uses dynamic mics nearly 100%. phantom is not even relative to that group.
My band is a prime example We've got a good studio built up where we practice. Everything is mic'd. Nothing requires Phantom w/the exception of the mics I bring in. In their 10 years prior to my involvement, they never once needed a condenser microphone.
That, and the other aspect of a deck like this is that its meant to take a signal from a larger mixing board. Where you might have many channels, but only can route 8 or so to a sub group output for mixing on a device like this...(where you could only use 4 at one time, and then maybe two pairs of RCA stereo inputs (as the pictures suggest) as chan 5-6 and 7-8.
Fwiw, the more I get into studio type recording and multi-tracking..., the less a device like this or any of the others does a damn' thing for me. One of the larger format recorders from Tascam that will take 24inputs..., simultaneously, that would be worth while.
Otherwise, a computer interface is the way to go.., at least thats the way my use is leaning
