Hello. I'm in the middle of a tape digitization project and I need to be able to handle both 1/2" 8 and 4 track tapes. I have a solid ATR-60 current configured with 8 track record/sync heads. Can I simply install a 4 track head into the sync slot and be able to play back 4 track tapes, or is more involved than that? The plugs appear to be the same for 4/8. Thanks!
