It has an ample heat sink for heat dissipation, and is also designed with a thermal shut-down circuit (for heat protection). Directing air flow over the cooling fins will dramatically improve heat dissipation. Do not enclose the amplifier in a smal

The LEVEL (gain) control located on the side of the amplifier is designed to do this. It is not a volume control. It adjusts the incoming signal level so that the source device and the amplifier reach maximum output at the same time. Th

This “bump” can have a dramatic effect on the bass system’s apparent volume. Use caution when adjusting this control, as subwoofer damage may result if the subwoofer begins to distort. When you exceed the subwoofer’s capabilities, the distortion will be obvious. To adjust bass boost: 1 Rotate the BA
