I have three of them which I use in the studio for cue mixes and sometimes for on location recordings. 3x8=24 you know.
Indeed it's a -10 board, but you can feed +4 recorders with it if you don't push them too hard.
The pre's are very good and clean sounding and it's probably one of the best sounding budget boards ever made, although a tad noisy.
The EQ is very neat, high at 11k, low at 45hz and a mid sweep.
It would hav been perfect with a low mid sweep extra.
There's a complete monitor section within the board that has a level control, panpot, FB send and a stereo effect send/returns, so you can use the board as an "inline" board as well as a split console.
It has 8 subs with switches to 9-16, so you can feed a 16 track without the need to patch wires.
I have made a number of very successful CD's with them boards, actually I'm searching for another (fourth) one.
I have an extra power supplie, but never needed it.
The board can work on car batteries as well.
Beware for worn faders, for I guess they're hard to find.
I understand the Seck company was sold to Soundcraft in the early 90's and Soundcraft used it for development of the Spirit line.
Great little board though, only 17 kilo's and very rigid too.
You can hear some sound fragments on my site that were done with the Seck. Ghotic example 1, Rock example 1 and jazz example 2 are from the Seck boards.
