With the GK 800RB amp 4 ohms is the MINIMUM load on the low side. Which means you can use a 1=4 ohm cab,2=8 ohm cabs,4=16 ohm cabs. The low side will not be damaged by a 8 ohm load. At 8 ohms the low side puts out 200 watts of power at 4 ohms the low side is rated at 300 watts.
: One, If you run both the 4ohm and 8 ohm cab it will result in the amp seeing a 2.67 amp load. I would be hesitant to do that without checking with GK to see
: if it will handle it. A GK rep told me DO NOT run a 4 ohm cab on the 8 ohm circuit of the 700 and 800 it will cause magic smoke to appear. TIC

: : : What was GK thinking when they designed the 700 and 800 biamp heads. The
: : : Woofer amp is 4 ohms. The mid highs is 8 ohms. Most low end cabs are 8 ohms
: : : so you can only get half the amp power available to them. Most, not all, 2-10 cabs,
: : : are 4 ohm. They can't be run on the 8 ohm circuit which is why I never looked any further at them! Screwy design.
: : yah i've heard that ... so if i get a 2x10 cab, would that work with my 400rb fine?? or would i start to loose power to the 15"???
