User manual BIAMP CPA130

[. . . ] 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. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. [. . . ] 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. The voltage selector is indicated on the rear panel at the power cord receptacle. If it is necessary to set the AC voltage selector for 240VAC operation, be sure to replace the AC fuse with the appropriate value. The High-Pass Filters must be enabled whenever using the CPA130 for driving distributed speaker systems (see Internal Modifications: High-Pass Filter on page 5).
