User manual PEAVEY CS 500A

[. . . ] Intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION: To reduce the risk of electric shock, do not remove cover. WARNING: To prevent electrical shock or fire hazard, do not expose this appliance to rain or moisture. Before using this appliance, read the operating guide for further warnings. [. . . ] The double red and yellow wires are the power amp outputs and are not interchangeable. The black wires are the power amp ground connections and are interchangeable. THE S2 OUTPUT MODULE (17) The S2 output module offers dual Speakon® Quick Connectors and a unique patching capability to wire these connectors to meet the particular application. the Speakon® is a four-wire connector with the connections labeled as 1+ , 1- , 2+ and 2-. Depending upon the loudspeaker needs, these connections can be used in various ways. NOTE: Consult your loudspeaker specifications to determine the wiring configuration (mode) that will best suit your system. This is the de facto standard for most low-to-medium power loudspeaker systems. ) This wiring requires one jumper per channel for a total of two; the other two are "stored". Please note for this wiring, both red binding posts are now connected to the Channel A output, and both black binding posts are now connected to Channel B output. Consequently, to connect additional speakers in bridge mode one must use a red and black binding post pair rather than connecting across both red binding posts as in the default arrangement. tHE S2 OUTPUT MODULE REAR VIEW 21 BIAMP MODE Option 4 (21) The final wiring arrangement is a natural progression of the Speakon® capability with its four wire connections. Biamping is often the preferred configuration for many sound reinforcement systems. In this case, two biamped wired loudspeaker enclosures can be connected to a CS-S amp via the two Speakon® connectors. First, the CS®-S amp must be configured for biamp with each channel signal supplied from a suitable crossover, and most importantly, the configuration is: Channel A as the "lows" and Channel B as the "highs". For this mode then, the wiring is: 1+ on both connectors wired to Channel A signal output; 1- on both connectors wired to Channel A chassis ground wire; 2+ on both connectors wired to Channel B signal output; 2- on both connectors wired to Channel B chassis ground wire. This arrangement again requires two jumpers per channel for a total of four. Always check the diagram and wire the module with care. For this wiring, both red binding posts are now connected to the Channel A output, and both black binding posts are now connected to chassis ground. Thus, both binding post red/black pairs are the biamped low output, and can be used to drive additional sub enclosures, if desired. INSTALLATION AND CONNECTION The Peavey CS® 500A commercial series power amplifier is designed for durability in commercial installations and the quality of performance required in studio and home applications. The unit is a standard rack-mount configuration, 3 1/2" high and is cooled by two variable-speed internal fans. All the input and output connections are on the back panel. [. . . ] Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point they exit from the apparatus. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. Unplug this apparatus during lightning storms or when unused for long periods of time.
