User manual BIAMP CPA650

[. . . ] Unplug this apparatus during lightning storms or when unused for long periods of time. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. [. . . ] Remove the knobs and the nuts from the level controls (use an 11mm or 7/16" nut driver). Move the level controls to their respective front panel mounting holes. Re-install nuts and knobs (hold onto controls to avoid twisting wires). NOTE: Relocation of Channel Level Controls must be performed by trained service personnel only. Input Barrier Strip: These barrier strip screw terminals are for connection of line-level input signals to the channels. For balanced inputs, connect High to (+), Low to (-), and Ground to (gnd). For unbalanced inputs, connect High to (+) and Ground to both (-) & (gnd). In monobridge mode, Channel 1 becomes the active input and the Channel 2 input is inactive. 5-Way Speaker Binding Posts: These 5-way binding posts are for connection of speaker loads to the CPA650. In stereo mode, the red (+) terminal of each channel is for connection to speaker positive, and the black (-) terminal for each channel is for connection to speaker negative. The CPA650 will deliver up to 325 Watts per channel into 4 ohm minimum loads. In mono-bridge mode, the red (+) terminal of Channel 1 is for connection to speaker positive, and the red (+) terminal of Channel 2 is for connection to speaker negative. The CPA650 will deliver up to 650 Watts mono-bridged into an 8 ohm minimum load. When using the CPA650 in mono-bridged mode, an autoformer is not necessary to drive 70V speaker systems. However, the load must be floating (neither side grounded) and capacitors should be used for isolation (see 70V Mono-Bridge Output on pg. Mono-Bridge Switch: This switch selects stereo or mono-bridge operation. In mono-bridge mode, Channel 1 is the active input and the Channel 2 input is inactive. The red (+) speaker terminal of Channel 1 is for connection to speaker positive, and the red (+) speaker terminal of Channel 2 is for connection to speaker negative.
