The PowerLight 6. and lower weight. this class H scheme creates essentially four different “full-power” levels within the amplifier channel. each channel has eight MOSFET devices arranged in a full bridge configuration. Audio circuitry The audio inputs are balanced to offer a high amount of commonmode noise rejection.9. Using them for linear audio amplification requires an unorthodox approach. 7 . Two models. resulting in loss of damping and in “clip sticking. as most amplifiers and other electronic equipment do. which is the signal faithfully while something most amplifiers maximizing efficiency. The pre-clipping scheme in the PowerLight 6.0PFC. increase electrical efficiency. These current signals are the controls for the output devices. Thus. The amplifier circuitry automatically and instantaneously switches to the lowest rail voltage that will allow the reproduction of the audio signal without discontinuity. yet the dynamic nature of music and other typical audio requires much less than full power most of the time. it does not prevent clipping. Each one has a local management circuit called a current cell that controls and linearizes the device by providing the necessary compensation to make the MOSFET’s conductivity track the signal current. The audio signal passes through a pre-clipper. the PowerLight 9. Figure 1. but reduces the amount of distortion to inaudible or barely audible levels. driving a single op amp differential amplifier. In addition. The degree of common-mode rejection is dependent on the close matching of the impedance between each leg and ground and around the differential amplifier. Most amps lose feedback during clipping. An all-pass filter uses group delay to slow the audio signal by 4 µs. They accomplished this by drawing current throughout the AC voltage waveform.0PFC. An amplifier with PFC draws current throughout the AC voltage waveform. Each amplifier channel has its own power supply.0PFC susceptible to RF interference. This reduces IM distortion by ensuring that the steps are executed before the audio signal in the output section reaches the transition thresholds.0 II was developed later.

In these three PowerLight amplifier models.7.5 Technical descriptions and theory of operation Power supplies QSC PowerLight amplifiers feature high-frequency switch-mode power supplies that help reduce noise.0 II keeps the output signal clean despite the flat-topping of the waveform. each has a small “housekeeping” supply that manages the turn-on functions before the main power supply starts up. Figure 1. The circuitry uses 1% precision resistors to ensure at least 40 dB of common-mode rejection. A power amplifier is most efficient at or near full power. instead of just at the peaks. high-frequency oscillations. The input balancing is done using an instrumentation amplifier arrangement.

To convert an amplifier from120 to 230 volts AC or vice-versa requires replacing both power supply modules and the AC line filter. adjusting it is far more complex than on most amplifiers.5 AC voltage conversions WARNING: Regulatory agencies require that any operating voltage conversions from 120 volts to any other voltage be done only by QSC’s factory service. or as an emergency measure if the module is running too hot at idle. Turn down the Variac to zero. 2. On the left side of the front panel. both power LEDs and both protect LEDs should be on. if anything. Technical Service Manual PowerLight 6. 6. you can safely increase the AC voltage to the amplifier’s normal operating level and test its audio performance.0PFC. and then off. The following procedure will help you determine if the amplifier has a problem and if so. it is usually safe to turn the AC up to the amplifier’s full operating voltage for further testing.

When it reaches about 25% of the amplifier’s operating voltage (30 volts for a 120-volt model or 60 volts for a 230-volt model). 4. and then the power supply resets and tries to start again. At this point. The main fuses are located in the line filter assembly and are accessible when the amplifier’s top cover is removed. 2. Protect LED lit • If the Protect LED lights steadily. or any other signs of short circuits or excessive current draw. and Protect LEDs: None lit on one or both channels • The main fuse for the affected channel(s) may be blown. Connect an AC voltmeter to monitor the transformer output and an AC ammeter to monitor the current delivered to the amplifier.

This is a rare failure because the housekeeping supply has very reliable protection against short circuits and other possibly destructive situations. and clip LEDs should light only in response to an output signal. If they do not. By the time it reaches about 40% (50 volts for a 120-volt model or 100 volts for a 230-volt model).3. For a PowerLight 9. If no such problems occur. Check current draw 7. of your troubleshooting efforts will be at board level. the power supply module is not working. the audio module cannot signal the power supply module to turn on. both protect LEDs should go out and all four fans should start up. quickly turn the AC back down to zero. Proper componentlevel troubleshooting and service will also usually require specialized test fixtures that may not be economically sensible to have unless you do a high volume of service work on these amplifiers. See the Servicing chapter of this manual for information on these fixtures. Without its housekeeping supply. and PowerLight 9. where it may be located. continue by following the preliminary troubleshooting guide. the power LEDs on both channels should start to flicker.

Attach the power supply remote controller (See the section on servicing power supplies in Chapter 2) to the ribbon cable. Start at zero volts 1. 24 QSC Audio Products. using wire 0 as a reference. Turn the variable transformer to zero and turn the amplifier off. Disconnect the latching connector on the cabling that goes to the input board. Disconnect the power supply control ribbon cable from the 8pin header on the audio module. Loosen the screw terminals of the five power supply wires at the front of the audio module. If the channel now starts up. Turn switch S1 on the remote controller to on and turn the amplifier on. there may be a problem with the portion of the housekeeping supply that is on the line filter assembly. 11. 7. Open the amplifier 2. then the problem was on the input board—perhaps a defective op amp. Remove the top cover of the amplifier.3 Further troubleshooting This procedure allows you to further isolate the problem and determine which board or module is defective. Inc. If the voltage is significantly lower or is not there at all. pull the connectors for the two housekeeping supply wires off of the audio module of the affected channel. If the voltage is good. Increase the AC voltage to 65 volts (120-volt model) or 130 volts (230-volt model). It should be approximately 40 volts DC. INPUT 1 16 VRE F NON-INV. K = cathode. PowerLight 6.0PFC. 8-pin SMT INV.
