Depends on the amp.
ALS-600 - no
Unmodified SB-200/220 - yes
FL2100 - yes

Basically put - check the voltage on the amp's relay line.  If it is AC, 
or a higher voltage, or if it is higher current to pick the relay, than 
is specified in the K3 specs - use the ARB-704.

And, yes, you can use the ARB-704 with any amp, even though it may not 
be needed.
