With six independent channels, the CP660 takes the place of three, two-channel amplifiers, yet still fits in a standard two-rack space. Its 75-watt average power output per channel is ideal for a variety of surround-sound uses, as well as many paging, zoning and background music applications. Plus, when you need it, you can easily bridge any pair of channels for double the power.
