The PA 150 is a rugged, medium-power amplifier with features that make it stand alone in the industry. It�s a rack-mountable unit which occupies only one rack space, and yet packs a 75 W RMS per channel punch into 4, 8, or 16 Ohms. It�s selectable; a feature seldom found on the typical solid state amp. In bridge mode, this unit delivers 150 W RMS into 8, 16, and 32 Ohms.You might ask why 32 Ohms; that�s the load impedance for a 150 Watt, 70 Volt distribution system.There�s no fan in this unit to make noise.Adequate cooling is provided by two massive heat sinks. Each channel is protected from excessive operating temperatures with a thermal/fault system that is automatic, and only activates under extreme conditions.The PA 150 has an exclusive SPS compression system that senses conditions which might overload the amplifier and activates compression circuitry when clipping is imminent.This technique utilizes every precious Watt available to power transformer with three different voltage taps.The rear panel three-position selector switch then gives this amp the impedance selection capability by changing the internal �rail� operating voltages.Toroidal power transformers offer very high efficient operation (cool), have very low magnetic fields (hum), and are relatively small in size (weight).All controls are located on the rear panel, and each channel is equipped with a separate level control.The inputs are electronically balanced. Both input and output are accessed via barrier strips.High slew rate, high damping factor, low distortion, and awesome features make the PA 150 the obvious choice for most demanding commercial/professional applications and permanent installations.Features * 19 rack-mountable * One rack space * 75W RMS per channel * 150W RMS bridge mode * Selectable 4, 8 or 16 ohms * SPS compression on each channel * Electronically balanced inputs * Convection cooledFront Panel * Heavy-duty rocker power switch * LED power indicator * SPS activation LED on each channelRear Panel * Barrier strip inputs * Barrier strip outputs * Detented 1dB level controls * Stereo/bridge mode switch * Impedance selector switch * Ground lift switchRated Output Power * Stereo Mode, both channels driven: 75W RMS per channel @ 4, 8 or 16 ohms * Bridge Mode, mono: 150W RMS @ 4, 8 or 16 ohms |
