Bogen Introduces New Class-D Public Address Amplifiers

gsamps-0216Bogen Communications is introducing a new series of Class-D amplifiers with 150-watt and 250-watt output and each with exactly the same features. The GS150D and GS250D models include a newly developed Class-D amplifier which enables less heat dissipation than previous Bogen Gold Seal Series models, saving cooling costs. They are up to 50 percent more efficient than previous models and including an upgraded contemporary set of screw terminal connections. The use of Class-D amplifiers also enables very low thermal emissions of 239.1 BTU/hour for the GS250D and 136.6 BTU/hour for the GS150D.

The Bogen Gold Seal Series Class-D amplifiers are an addition to Bogen’s line of high-quality audio amplifiers. With the incorporation of the Class-D amplifier, the GS250D (at 320W of power consumption and weighing just 19.5 lbs.) is 42 percent more efficient and 55 percent lighter than previous 250-watt models, while the GS150D (at 190W of power consumption and weighing in at 18.5 lbs.) is 50 percent more efficient and 65 percent lighter than previous 150-watt models. Another benefit for rack installations is that the GS250D and GS150D have the same chassis dimensions as Bogen’s previous GS250 model. (GS150D chassis height and width are the same as GS150, while the length is 1.5″ longer.)

Features include:

  • Two-piece pluggable Euro block-type connectors enable signal cables to be more quickly               connected/disconnected from the amp
  • Four dedicated MIC inputs
  • One selectable MIC/TEL input
  • One selectable MIC/AUX input
  • One dedicated AUX input
  • 4-ohm, 8-ohm, 25V, 25VCT and 70V transformer-coupled outputs

The Gold Seal Series Class-D amplifiers are listed to UL standard 60065 and here are the specs.
