The Bogen GS150 is a 150 watt amplifier with 7 inputs and a 10 band equalizer. Six inputs accept low impedance balanced microphones and have phantom power. Four of them have standard 3-pin mic jacks. Two of the inputs will accept auxiliary inputs such as CD or tape deck. The unit is at the top end of the Bogen line, and is a reasonable unit for sound reinforcement.
