Yes; XLR jacks for in and out. The 122 II and III have a switch to go between balanced (XLR) and single-ended (RCA). I don't remember on the first 122, but I think it also had both... it's been a minute...
Teac equipment may be the same circuit internally (there was a lot of "dual-use" decks with home/pro being the same with a different face), but do not have the provision for balanced operation (or the ability to add the balanced module, which other Tascams do- a removeable panel in the rear where the appropriate interface plugs in and replaces the blanking plate with the XLR in/out)
Tascam often had rack mounting provisions as well- open reels were removeable but cassette (and DAT, MD etc.) all had the ears integrated into the front panel. I think only the original 122 had rack "handles"; the II and III seem to have holes but no handles.
