INTRODUCTION- General Overview

Thank you and congratulations on your purchase of the QSC PowerLight 6.0 II professional power amplifier. This product represents the state-of- the-art in power amplification systems for professional touring, permanent installations, and other SR (sound reinforcement) applications requiring high levels of sustained power, extraordinary audio performance, reduced weight, and road-proven reliability. To get the most from your investment, we encourage you to review this manual carefully.

Part of the advanced technology PowerLight family of amplifiers, the PowerLight 6.0 II benefits from QSC’s exclusive PowerWave switching technology, its DataPort for remote computer control, and an enhanced design that provides greater airflow through the chassis— facilitating cooler, more efficient operation.

QSC PowerWave Technology

QSC’s PowerWave switching power supply technology provides ample current to the audio power circuitry by charging the supply rails 180,000 times per second through an ultra-low impedance circuit. This high-efficiency design

cuts waste heat and boosts reliability while delivering the added benefits of tighter bass and transparent highs for a more musical sound.

The PowerLight 6.0 II utilizes an enhanced, second-generation power supply design. This new design reduces both EMI (electromagnetic interference) and the overall weight of the unit—enabling far greater placement options when positioning equipment. In the unlikely event your unit ever requires service, the new power supply design offers several additional benefits—including greater ease of service, resulting in reduced labor time and lower replacement costs.

Remote Computer Control

The PowerLight 6.0 II also incorporates QSC’s unique DataPort for remote computer control. Using QSControl, QSC’s network audio system, you can monitor and control hundreds of amplifi- ers simultaneously, as well as perform a wide range of advanced functions—including event logging, checking the thermal status of the amplifier, plus real-time monitoring of loud- speaker opens and shorts.

What’s the difference between the “new” PL6.0 II and the “old” PL6.0? The chart, right, compares the two. Output power and AC current consumption are the specifications that have changed slightly. Output power is - 0.9dB at 8 ohms, and -1.04dB at 4 ohms. 2 ohms power remains unchanged. AC current draw variations are a result of power factor correction removal and power supply topology changes. These changes improve reliability of the amplifier under the most demanding output conditions.
