In general, ALC should NEVER be used to set drive level -- doing so will 
generally cause MASSIVE splatter and clicks. I have no experience with the 
ALS600, but I've used my K2/100, K3/100, TS850, and Omni V to drive Ten Tec 
Titans (tubes), Herc I (solid state), and Herc II (solid state) power amps. 

1) There IS a delay built into the K3's circuitry that keys the power amp. 
The delay is adjustable, and the defalut settings work very well with most 
amps. You can easily change the delay with a menu setting. 

2) To set the power level, simply start with low output from the K3 (I'd 
start with 10-20 watts) and bring up the output power of the K3 (using the 
Power knob) until you hit the recommended power output of the amp. My Ten 
Tec amps all produce full power with less than 50 watts drive.
