User manual QSC AUDIO POWERLIGHT 3.4 REV E

[. . . ] 8- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9- Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one blade wider than the other. A grounding-type plug has two blades and a third grounding prong. [. . . ] The DataPort is a QSC-specific connection used for interfacing amplifiers, amplifier monitoring devices and signal processors. It is typically used in larger-sized installations where amplifiers may be located far away from system operators. The DataPort interconnects provide audio inputs to the amplifiers and amplifier operating data (temperatures, power status, audio power level, etc. . . . ) to other QSC equipment, such as the CM16a Amplifier Network Monitor. Managing all this information and the operation of the amplifiers is QSC's QSControl software running on a PC. QSControl primarily handles amplifier tasks, while another QSC program, Signal Manager, handles Processor configuration. If you are not using the PL6. 0 II with QSControl, QSC DSP-3, QSC DSP-4 or other QSC DataPort accessory, do not use the DataPort. DataPort Cables Use only QSC Audio DataPort Cables for DataPort connections. Molded-connector DataPort cables are standard. Premium DataPort cables (made to order with hand-wired termination) provide individually shielded audio pairs for the best possible audio performance. Either type of QSC DataPort cable is available from QSC's Technical Services Group. Computer VGA cables are similar, but can degrade your audio quality; we do not recommend their use. Bridge mode uses only one output channel connection. Refer to the chart below for connection diagrams. Mode Switch position is shown for reference. SpeakonTM pinout is provided on the following page. Do not use less than 4-ohm loads in Bridge mode!Note polarity of connections for Bridge mode. Speakon connections do not support Bridge mode. Do not use banana-type plugs for connecting to binding posts. They will fail at the high power levels of this amplifier! 17 CONNECTIONS- Outputs: SpeakonTM pinout Speakon Outputs The Speakon outputs are for use in Stereo and Parallel operating modes. Minimum speaker impedance when using Speakon connection is 4-ohms. 2-ohm load-connection to Speakon is not recommended; output power of this amplifier exceeds Speakon capability at 2-ohms. [. . . ] Tighter Bass A PowerWave transformer has lower impedance and greater efficiency because its copper windings are short and thick. In essence, it provides a "bigger pipe" to get electrical energy to the amp's output circuitry. A stiffer power supply that delivers chest-pounding bass. Cleaner Sound The PowerWave supply in the PL6. 0 II charges the rails 180, 000 times per second--a vast improvement over 100­120 times per second in conventional supplies. [. . . ]
