The A-S3200 (B/PB) from Yamaha belongs to the family of solid stereophonic integrated amplifiers. The integrated amplifier combines a pre-amplifier and a power amplifier in one device, so it can directly accept the signal from the respective source (cd/dvd player, turntable, radio, etc.) and transfer it to the speakers for playback. In this case, it operates with transistors or otherwise solid state. The power is 150W/4Ω or 100W/8Ω. It has a phono input.
Note: The phono input allows you to connect a turntable without an integrated preamplifier directly to the amplifier without connecting an intermediate and separate preamplifier.
