Integrated amplifier FT-B2813P

This is a 130W power amplifier with five input channels (three microphones, two lines) and multiple output options (100V, 70V constant voltage, and 4-16Ω constant resistance). It offers independent volume and tone controls, automatic mute for MIC1, and built-in short circuit and over-temperature protection. The unit features a temperature-controlled cooling fan and an elegant aluminum design.
