Mike-
First your Question #2:
I have owned Yamaha o1v's for years, using them for three primary functions.
1. Sidecar FX mixers on large-input shows.
2. When touring with a small opening act.
3. As a live recording console. Taking something like group feeds from my FOH console, and then being able to delay my board feeds to my FOH audience mics, using the individual channel delays found on the o1v's has always worked great for me.
( The TT24 does NOT have individual channel delays, and this is an essential function for me and my company. )
When comparing the o1v and the TT24, here's some of the observations I made.
- The TT24's pre-amps sounded better. No question.
- The overview window on the TT24 was far more comprehensive, and I liked the layout much better than the o1v's.
- The dynamics processing on the TT24 was more effective than the rather severe settings I have gone with on the o1v at times.
- The click and drag features and graphic visuals on the equalizers and dynamic processors on the TT24's software were extra quick, and effective.
- While many people are familar with the SPX effects engines found on o1v's, I was able to edit the TT24's to precisely what I wanted - I was happy with their quality as well.
- Obviously, a touch screen on the TT24.
I have owned o1v's since the first model ( 1998 ), so my ability to navigate and relay an objective opinion on " Logical Layout " of buttons and features is skewed. Fellow engineers say I know the console in Braille.
I did have initial difficulty with the Mackie, but that curve is rapidly straightening out.
Now Question One: PFL was mono, but you could solo each side of the linked auxes, not just the left.
AFL was indeed stereo.
Overall, I do like the TT24 better than the DM1000 or the o1v, primarily because of the pre-amps. One could always get a rack of nicer pre-amps and lightpipe your way into a Yamaha to overcome, and still maintain the smaller footprint.
I have always loved my o1v's for exactly the usage I described above, but as soon as the TT24 will allow me to delay individual channels I will probably switch over, but won't decide until I take the TT24 on it's big upcoming ROAD TEST assignment - the Joshua Tree Music Festival, May 19-21.
