User manual QSC AUDIO POWERLIGHT 6.0 II

[. . . ] PowerLight 6. 0 II User Manual *TD-000108-00* TD-000108-00 rev. A PowerLight Series TM 1 IMPORTANT SAFETY INSTRUCTIONS & EXPLANATION OF SYMBOLS 1- Read these instructions. 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. If the provided plug does not fit your outlet, consult an electrician for the replacement of the obsolete outlet. [. . . ] 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. Connecting Orient the DataPort cable's male HD-15 plug with the DataPort receptacle, insert fully, and fingertighten the retaining screws. If using the DataPort only for control and monitoring of amplifier functions and NOT audio input, then the audio input may be connected to the "normal" combo or terminal-block connectors. If audio inputs are active on both the DataPort and normal connections, they will be summed, producing unexpected results. If connecting a QSC DSP-3 or DSP-4 module to the PL6. 0 II, make sure the DataPort cable between the amp and the DSP module has pin #9 removed from either end. See DSP module documentation for details. 14 CONNECTIONS- DataPort (QSControl users only) Typical DataPort Application Refer to QSControl and DataPort Accessory documentation for connection details. Use only QSC Audio DataPort Cables for DataPort connections available from QSC's Technical Services Group. . *Required interface* If amplifier Power Status is to be controlled with remote network applications (QSControl), be sure to leave the amplifier's AC power switch in the ON position. Place amplifier in STANDBY mode using the amplifier network control software. If the AC power switch is OFF, the amplifier will be unable to respond to any commands. 15 CONNECTIONS- Power Supply Control (Standby/Enable) Remotely Controlling the Amplifier's Power Status The PL6. 0 II provides two methods for remotely controlling its Power Status: 1- the Power Supply Control connection 2- the DataPort connection (using QSControl) Two status modes are possible: STANDBY and ENABLE. Using the Power Supply Control connection, all that is required is a switch and some twoconductor cable. If using the DataPort connection, refer to QSControl's help file for more information. In order for the amplifier to respond to STANDBY and ENABLE commands, whether from the rear-panel connector or DataPort/QSControl, the AC Power Switch MUST be in the ON position. If remotely controlling the AC Power Status, turn the AC Power Switch ON. Place the amplifier in STANDBY by using the rear-panel Power Supply Control connections or by using the appropriate QSControl software, connections, and commands. Using the Rear Panel Power Supply Control Connector Included with the PL6. 0 II is a 2-pin terminal block connector for the Power Supply Control. switch, and the connector, wire the control as shown in the diagram, right. When the switch contacts are open, the amplifier will be operating normally (on). When the switch contacts are closed, the amplifier will be in Standby mode. Power Supply Control 2-pin connector is located between the DataPort and CH2's Speakon. 16 CONNECTIONS- Outputs: Binding Posts Connecting the Outputs to the Speakers Use either the binding post or the SpeakonTM output connections. Binding posts are covered on this page, Speakons on the following page. Note that the PL6. 0 II does not support Bridge mode output from the Speakons (see page 11). There are two basic speaker connection configurations for the PL6. 0 II. [. . . ] 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. 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. This high recharge rate minimizes AC ripple that can degrade sonic quality. Worried about power supply induced hum? [. . . ]
