User manual BIAMP CPA130

[. . . ] WARNING - To reduce the risk of electric shock, do not expose this apparatus to rain or moisture. The apparatus shall not be exposed to dripping or splashing and no objects, such as vases, shall be placed on the apparatus. 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. [. . . ] 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 CPA130. 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 CPA130 will deliver up to 65 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 CPA130 will deliver up to 130 Watts mono-bridged into an 8 ohm minimum load. Autoformers are available from Biamp Systems, which allow the CPA130 to be used to drive 25V, 70V, or 100V distributed speaker systems (see Internal Modifications: High-Pass Filter on page 5). When using the CPA130 in stereo mode, the appropriate autoformer for each channel is a DT-2A. When using the CPA130 in mono-bridge mode, the appropriate autoformer is a DT-3A. Mono-Bridge Switch: When depressed, this switch selects the mono-bridge mode of operation. In mono-bridge mode, Channel 1 becomes 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. The CPA130 will deliver up to 130 Watts mono-bridged into an 8 ohm minimum load. 7 PRECAUTIONS Be sure that power to the CPA130 is turned off when making all connections. High voltages can be present at the speaker terminals, and static pops or broken ground connections on cables can cause speaker damage. Use speaker wire of sufficient gauge to prevent power loss and damping factor reduction. Larger size wire has a lower resistance and permits longer cable runs. Use 16 or 18 gauge wire for cable runs up to 20 feet. For runs longer than 80 feet, use 10 or 12 gauge wire. Check the AC voltage before connecting the AC cord. The voltage selector is indicated on the rear panel at the power cord receptacle. The CPA130 is shipped from the factory set for 110VAC operation.
