6 The PL6.0 II is highly durable and is carefully packaged. We recommend you inspect the unit carefully after removing it from the packaging, as occasionally there may be damage due to some unfortunate incident during shipment. Report any damage to the shipping carrier .
7 SETUP- Rack Mounting Supporting the Rear of the Amplifier For mobile and touring use, it is extremely important to support the rear of the amplifier .
8 SETUP- Cooling Requirements The PL6.0 II has four rear -mounted variable- speed fans. Fan speed is determined by the temperature of the amplifier’ s internal heatsink assembly . Cooling air is drawn into the rear of the amplifier by the fans and exhausts through the front panel.
9 SETUP- AC Power Requirements AC Power Before connecting the amplifier to the AC mains, check the serial number plate to verify operating voltage. The PL6.0 II is available in 120 or 240 V olt models. Make sure the AC mains voltage is the same as specified on the serial number plate.
10 SETUP- Operating Mode Selection Stereo Mode Operating Mode Selection The operating Mode selection switch determines how the inputs are routed to the two amplifier channels and how the outputs are connected to the speakers. The Mode selection switch is located on the rear panel, left bottom corner .
11 Parallel Mode Bridge Mode In Parallel Mode, the channel 1 and channel 2 input connectors are connected in parallel. Applying an input signal to either input will drive both channels. Make sure only one input signal is applied to the ampli- fier when operating in Parallel mode.
12 Audio Input Connections CONNECTIONS- Inputs Input connections to the PL6.0 II can be made with XLR, TRS (1/4-inch), or terminal-block connectors. The XLR/TRS connectors are “combo” style; they accept either XLR or TRS type inputs. The terminal block connectors are three-pin “Euro-” (or “Phoenix-”) type.
13 XLR CONNECTIONS- Inputs: XLR, TRS (1/4-inch), and T erminal-block Pinouts TRS (1/4-inch) T erminal-block Connectors phone plug (tip-sleeve) shield jumper from “–” to shield shield Balanced Un.
14 The DataPort is a QSC-specific connection used for interfacing amplifiers, amplifier monitor - ing devices and signal processors. It is typically used in larger -sized installations where amplifiers may be located far away from system operators.
15 CONNECTIONS- DataPort (QSControl users only) Use only QSC Audio DataPort Cables for DataPort connections available from QSC’ s T echnical Services Group.. If amplifier Power Status is to be con- trolled with remote network applications (QSControl), be sure to leave the amplifier’ s AC power switch in the ON position.
16 CONNECTIONS- Power Supply Control (Standby/Enable) Remotely Controlling the Amplifier’ s Power Status Power Supply Control 2-pin connector is located between the DataPort and CH2’ s Speakon. Using the Rear Panel Power Supply Control Connector Included with the PL6.
17 CONNECTIONS- Outputs: Binding Posts Connecting the Outputs to the Speakers Use either the binding post or the Speakon™ 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).
18 CONNECTIONS- Outputs: Speakon™ 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.
19 USE- AC Power Switch and LED Indicators LED Indicators for Power Status On the left side of the front panel is the Power switch. The switch is labeled ON, above it and to the right. T o turn the power on: Press in on the upper portion of the rocker switch.
20 USE- Signal Level LED Indicators LED indicators. USE- Gain Controls Gain Controls A Gain control adjustment is provided for each channel. The voltage gain of the amplifier (in dB) is marked around each control. Rotating the control clockwise increases the gain of the amplifier .
21 USE- Clip Limiters Clip Limiters The PL6.0 II has separate clip limiters for each channel which respond only to actual amplifier clipping. Amplifier clipping generates internal error signals which cause the Clip Limiter to quickly reduce gain and minimize the overdrive.
22 TROUBLESHOOTING The amplifier “cuts-out” when I really crank it up (intermittent operation)- • Make sure the AC power source is rated for the required current! Use only 10-gauge heavy-duty extension cords.
23 TROUBLESHOOTING I am trying to use QSC’ s DSP-3 or DSP-4 signal processor , but it doesn’ t power up when the amp is turned on. What’ s wrong?- • Nothing. The PL6.0 II does not supply the required power to the DSP-3 or DSP-4 module. • An accessory AC adaptor (wall wart) will be required for the DSP-3 or DSP-4.
