A:Answer Hello. The AMP 30 is very versatile in that it can also be used in bi-amp and BTL (bridge-tied load) mode. With it's regular delivery, the AMP 30 can effortlessly power the vast majority of modern speakers in a regular domestic setting. Should you have speakers with a particularly challenging load, bi-amp or BTL mode could well prove to be worth utilizing. The only other thing you will need to consider is how many speakers you plan to drive. The AMP 30 can drive 6 speakers, but in bi-amp or BTL mode, it drives three speakers (front left, right and center channels for example).
