600W power amplifier bipolar circuit

The power amplifier delivers 600 watts into 8 ohms (bridge mono) or 300 watts into 4 ohms (stereo) -
ideal for clubs, churches, auditoriums and more.

Admission to the 600W bipolar amps is achieved via XLR or phone jack, and output is achieved through two Speakon-type connectors or terminals.the 600W [...]

This circuit is a stereo amplifier for a high sensitivity stereo parabolic microphone that able to used for listening to distant sounds. Typical parabolic microphones are monophonic, this unit has a stereo audio path that helps produce more realistic sounding audio. The Big-E can be used with headphones or as an audio source for a [...]
