FRONT PANEL FEATURES

AC POWER SWITCH

•Controls all power to the amplifier. The AC Switch must be ON to use remote controlled Standby mode. The Blue POWER LED should illuminate whenever Power is ON, either in Standby or Run.

•On the PL-380, it is normal for the Clip LEDs to remain on for 15 seconds after removing power. The red LEDs indicate prompt muting to prevent turn-off noises.

CLIP LED (Red, Each Channel).

•The LED glows bright red while amp is muted for any reason. This normally occurs each time the power is turned on or off. Muting at other times indicates overheating or other protective behavior.

•The LED flashes bright red during clipping. The intensity and duration correlates with the audibility of the clipping.

•The LED glows half-bright during limiting. This may occur on all products when the Clip-Limiting circuit is enabled. The PL380 also uses limiting to protect against overheating, excessive high frequency output, and prolonged power overload.

-10dB LED (Orange, Each Channel).

•Illuminates when the amplifier channel reaches the last 10dB of its power range (between 10% and 100% of rated power). The LED is orange to warn that clipping is being approached.

-20dB LED (Green, Each Channel).

•Illuminates when the amplifier channel is 10-to-20dB below clipping (between 1% and 10% of rated power). This should normally be a “safe” zone of operation.

SIGNAL LED (Green, Each Channel).

•Illuminates when the signal level reaches -35dB, which should produce an easily audible sound in the speakers. If this LED remains illuminated when no signal is expected, there may be interference or some other abnormal condition.

POWER LED (Blue)

•The Blue POWER LED should illuminate whenever Power is ON. It may dim visibly when the amp is in Standby.

BRIDGE LED (Yellow)

•Warns that the rear panel Bridge Mode switch has been set. The LED color matches the rear panel readout. See BRIDGE MONO MODE on next page.

PARALLEL LED (Orange).

•Warns that the rear panel Parallel Mode switch has been set. The LED color matches the rear panel readout. See PARALLEL INPUT MODE on next page.

GAIN CONTROLS

•Each channel has a 21-step Gain control with approximately 20dB of input headroom. 1dB steps are maintained down to 14dB of attenuation, with increasingly large steps below this point as marked.

•Gain reduction may be used as desired to reduce input noise, but will reduce the headroom available to the Clip Limiter. Use the threeposition GAIN SENSITIVITY SWITCH (below) to match the dynamic range of the amplifier’s input to that of the source, permitting normal, nearly-full Gain settings.

LOCKOUT COVER MOUNTING

•The Gain controls can be made tamper-proof using two methods.

•The lockout cover packed with this amplifier keeps the LEDs visible but makes it appear there are no Gain controls at all. Preset the Gain controls and remove the knobs carefully by pulling straight out. Partially remove the screw located on the outside edge of the faceplate, using a 9/64" or 3.5mm hex tool. Slide the notched end of the lockout cover under the screw, let the left end drop into the last vent, and slide to the right until both ends seat flush with the faceplate. All LED holes should now be aligned. Carefully tighten the screw.

•Alternatively, individual Gain knobs can be removed and covered by the included hole plugs.

FRONT PANEL VENTILATION SLOTS

•QSC amplifiers pull air from the rear, and exhaust it from the front, thus allowing the heat to dissipate without heating the rack. As the amp works harder, the fan will speed up and expel more hot air. The exhaust temperature can easily be sensed, unlike rear-exhaust amplifiers that may seem cool in front but which may be dumping hot air into the rack.

•Users will notice that the PL380 idles noticeably warm. This is normal for Class-D technology, which is always processing some power and is therefore “in gear” at all times. There is plenty of cooling capacity, and the temperature will hardly budge until operated at very high power levels.

MOUNTING THE OPTIONAL HANDLES

•The handles are packed with the required Phillips-head screws. Mount the screws through the round holes located inside the rackmounting ears.

REAR PANEL FEATURES

INPUT CONNECTIONS

•Precision balanced inputs offer superior hum rejection, and accept >21dBu input levels on all Sensitivity settings (see Specs).

•Female and Male XLR, Pluggable Terminal Blocks, and DataPort Input signals are all wired in parallel for each channel.

•Paralleled DataPort routing is used for the first time on the PL3 series. Therefore, DataPort-connected signals can be patched to other amplifiers. Do not use unbalanced connectors as this will unbalance and possibly affect the level of all signals connected to that channel.

•Because the DataPort signals on the PL3 Series are connected like any other input, the Sensitivity switch will affect gain for these inputs as well. QSControl devices will read the setting of the Sensitivity Switch to allow for this.

REMOTE MONITORING – DATAPORT

•All DataPort connected accessories are supported. The usual signals representing output voltage, output current, clipping, temperature, supply voltage and switch status are provided, plus remote control Standby. The current version of QSControl will read a unique ID code and know what PL3 models are connected without operator intervention.

CLIP LIMITING, ON-OFF SWITCH (Ch1, Ch 2)

•Each channel provides a Clip-Limit switch; with an adjacent yellow LED for “ON”. PL3 Clip Limiting is designed to reduce the audibility of clipping without changing the program dynamics in any other way. It replaces harsh clipping with very rapid limiting, “reducing” rather than “eliminating” clipping. This is not a substitute for long-term power limiting, as average program levels can still be driven very high.

HIGH PASS FILTER, 3-POSITION SWITCH (Ch1, Ch2)

•For simple systems, second-order (12dB/octave) filters can be engaged at 30Hz (yellow LED) or 50Hz (orange LED). These filters can prevent speakers from sub-audio overload, but can have an audible effect on percussive material. Their effect should be auditioned carefully. When bypassed (no LED), the low frequency response extends to about 3Hz. In this wideband mode, very large sub-audio transients may trigger brief protective muting.

INPUT MODE SWITCH, 3-POSITION: BRIDGE, STEREO, PARALLEL

•BRIDGE MONO MODE (Yellow LED): Sends Ch1 signals out-of-phase to Ch2, producing twice the normal voltage swing between the two “red” speaker terminals (Ch1 “red” is defined as positive). Only Ch1 controls and input are effective. USE EXTREME CAUTION when connecting speakers. Depending on the model, hundreds of volts and thousands of watts are available. NOTE: it is normal for the Br Mono indicator LED to change slowly.

•STEREO MODE (Green LED). Each channel operates independently, as usual.

•PARALLEL INPUT MODE (Orange LED). The inputs of both channels are directly connected together, but all controls and speaker connections work as usual. Never connect the red output terminals directly together.

INPUT SENSITIVITY SWITCH, 3-POSITION: 26dB, 32dB, 1.2V

•The 26dB (Orange) and 32dB (Green) settings provide the same voltage gain for all models. When using these settings, all models will sound equally loud, but the more powerful amp will have more headroom.

•The 1.2V setting provides the same input sensitivity for all models. Larger amps will sound proportionally louder, with the same amount of headroom.

•The resulting input sensitivities and gains for each model are shown in the Specs.

SPEAKER CONNECTIONS – SPEAKONS

•Ch1 provides “4-wire” access to both channels using the standard convention: Ch1 uses 1+, 1-, and Ch 2 uses 2+ and 2-.

•Ch 2 provides “2 wire” access to Ch 2 only, using 1+, 1-.

SPEAKER CONNECTIONS – BINDING POSTS

•WARNING: use safe wiring practice as peak output voltages can be hazardous.

AC POWER CABLE AND AC VOLTAGES.

•PL3 Series amplifiers are configured for specific AC voltages. The products operate safely over the normal range of AC line variation but rated performance applies only at rated voltage.

•Where regulations permit, products feature locking detachable cordsets, and are shipped with AC plugs suitable for the intended AC voltage (see Specs).

Rack Mounting and Dimensions

Use four screws and washers to mount the amplifier to the equipment rack rails. To use the amplifier outside a rack, attach the self-adhesive rubber feet to the bottom.

For portable, mobile, or other applications where the rack assembly may be moved, we strongly recommend supporting the rear of the amplifier. A rear rack ear kit is available from QSC’s Technical Services Group.

Optional rack handles provide finger grips at each end, making lifting and setting into the rack more comfortable.

Serie PowerLight 3

Amplificadores de potencia profesionales

Le agradecemos que haya seleccionado a PowerLight 3 para satisfacer sus necesidades de amplificación. Ahora pertenece a una comunidad internacional de profesionales que confían en el rendimiento de los productos QSC bajo cualquier condición. La visión de QSC es convertirse en el proveedor más fiable de productos y servicios de sonido de alta calidad para los artistas y profesionales de todo el mundo. Ganamos esa confianza gracias al diseño minucioso, pruebas rigurosas y una atención obsesiva a la calidad y al detalle en todas las fases de la fabricación y el servicio.

Los productos de la serie PowerLight 3 se basan en décadas de investigación y experiencia en la amplificación de la potencia sonora. Esta serie combina los ajustes de entrada analógica de mayor demanda con indicadores LED de fácil lectura, lo cual facilita la inspección de los ajustes de un vistazo y su adaptación a cualquier sistema. Como no hay procesamiento digital interno ni demora de la señal, estos amplificadores pueden combinarse libremente con todo tipo de amplificadores tradicionales. El DataPort de QSC proporciona acceso a una variedad completa de procesadores digitales y sistemas de supervisión de control remoto de QSC.

Los modelos PL325 y PL340 continúan con el legado de PowerLight que comenzó en 1994, combinando un suministro eléctrico de funcionamiento con conmutación potente, ligero y eficiente con nuestra sección de salida linear Clase H más avanzada. Su rendimiento sonoro de calidad de referencia, alta capacidad térmica y solidez idónea para las giras artísticas continúan a la cabeza de la industria.

El modelo PL380 combina el suministro PowerLight con una sección de salida de audio Clase D, duplicando la potencia de salida a la vez que reduce aún más las pérdidas. La sección de salida Clase D supera el rendimiento de la mayoría de los amplificadores lineales de la competencia, ofreciendo el mejor rendimiento de sonido de variación total disponible en este intervalo de potencia. Todos los modelos tienen una respuesta sonora característica, impulsando hasta las cargas difíciles sin comportamientos o cambios molestos en la calidad del tono.

Para controlar con seguridad y sin complicaciones la potencia de miles de vatios, los amplificadores QSC emplean muchos sofisticados circuitos de protección. Estos sistemas proporcionan la variedad dinámica más amplia posible sin permitir que el amplificador exceda sus límites de operación seguros. Para evitar la activación involuntaria de estos sistemas de protección, y para proteger sus valiosos altavoces, por favor revise estas instrucciones y asegúrese de obtener el beneficio completo del rendimiento de su amplificador.
