Power Amplifier





PA-2100


Data Sheet:   PA 2100


Power: 2 x 100W @ 8 Ohm or 2 x 100W @ 4 Ohm or 2 x 100W @ 100Volt

The PA-2100A Power Amplifier from IRP professional sound products is a 100 watt per side dual-monaural output device. The PA-2100A features improvements designed to address the needs of today’s system integrators, such as internal torroidal output transformers. The front panel graphics have been designed to match the appear-ance of the other power amplifiers in the PA-Series product line. This new unit employs a dual monaural design for improved reliability. The PA-2100A output power rating has been designed to provide a midrange unit that meets the needs of IRP customers and clients. Similar to other power amplifiers in the PA-Series, the unit occupies a single rack space mounting. With convection cooling and a fully enclosed chassis, the inherent problems of fan noise and susceptibility to environmental problems such as dust, smoke and liquids have been reduced to near negligible levels.
Designed for the Global Market, IRP decided that the PA-2100A had to be one of the most easily specified and installed power amplifier available.
These design criterions are reflected in the overall design and feature set. The amplifier is able to operate on 120 or 240 volt ac power at 50/60Hz. This highly stable discrete power amplifier has a power handling rating as shown
