Bogen Communications BPA60

The Bogen BPA60 solid-state power amplifier has been designed to fulfill the power amplification requirements of professional and commercial sound systems. The Model BPA60 supplies 60 watts RMS output. Total harmonic distortion is less than 2% at rated output from 50Hz to 5kHz.  Input impedances for the BPA60 are: high-impedance (50k-ohms) unbalanced; and low-impedance (500/600 ohms, balanced or unbalanced) with accessory transformer Model TL600. Line-bridging may be achieved with accessory transformer Model TL100. Hum and noise are at least 85dB below rated output.   The BPA60 amplifier may be driven from an amplifier that provides a 25- or 70-volt output. Output impedances for the BPA60 are: 8-ohm/25V, 16-ohm, 25VCT and 70V. Output regulation is better than 2dB from no load to full load.  The BPA60 amplifier is thermally protected to prevent damage due to excessive temperatures; however, it will deliver the full rated output continuously, even at +130° F (+55° C). Additional protection is provided by transient protection diodes and an electrical circuit breaker.  An illuminated on/off power switch is located on the front panel. An input level control, circuit breaker reset, lo-cut filter switch, and auxiliary receptacle are located on the rear panel. A rack panel kit (RPK53) is available for mounting the amplifier in a 19-inch equipment rack.
