I must admit, the gain setting implementation of this amp is pretty crap. Seriously, a nearly $7000 amp should do better.Actually, there's a gain selection that you can set with the remote controller.
Hold the mode button on the remote controller (the O button in the middle) for 3 seconds. The LEDs will start blinking. With the up/down buttons on the remote, choose V1 or V2. V1 is low gain and V2 is high gain. Press the mode button again for 3 seconds to set it.
