The Yamaha Stagepas 400BT PA speaker set is a portable system featuring a powered mixer and two two-way speakers, each with an 8-inch woofer and a 1-inch high-frequency compression driver. The mixer has 8 channels, SPX digital effects with four reverb types, a two-band equalizer on each channel, and a built-in feedback suppressor. Bluetooth 4.1 supports wireless audio streaming over a range of approximately 10 m, while the Hi-Z inputs allow electric instruments to be connected without a DI box.

The system features phantom power, monitor and subwoofer outputs, and an input for a Yamaha FC-5 footswitch to activate the reverb. The speaker cabinets can be placed on the floor at a 50° angle for use as monitors. Speaker connection cables are included.
