The Continuation of the STAGEPAS Series, Designed for Mobility
Designed in the spirit of the acclaimed STAGEPAS packs, the 400BT retains the intuitive ergonomics and reliability of the range while adding modern connectivity. This compact solution offers lightweight amplification, a detachable mixer, and optimized speakers delivering up to 125 dB SPL per speaker, ideal for mobile performances.
Intended Uses and Target Audience
Whether you are hosting an acoustic concert, a conference, a fitness class, or a family party, the STAGEPAS 400BT provides clear and even sound coverage. Its 4 mic/line inputs, stereo channels, and Hi-Z mode (CH4) accommodate microphones, keyboards, electro-acoustic guitars, and audio players, while remaining user-friendly for non-technical users.
Key Features for Immediate Sound Setup
Integrated 8-Channel Mixer
The mixer offers 4 mono mic/line channels and stereo inputs, with 2-band EQ per channel (high at 8 kHz, low at 100 Hz). SPEAKERS, MONITOR (L/Mono, R), and SUBWOOFER (mono with automatic filtering) outputs facilitate system expansion depending on the venue.
Built-in Processing and Feedback Prevention
SPX reverb (4 programs with parameter control) adds space to vocals and instruments. The feedback suppressor and "1-Knob Master EQ" help tailor the sound to the room within seconds.
Bluetooth Streaming and 2-Way Speakers
Wireless playback simplifies musical atmospheres and jingles. Each 2-way bass-reflex speaker (20 cm / 8-inch woofer, 2.54 cm / 1-inch compression driver) offers 90 x 60 dispersion and can be used as a floor monitor (50deg angle) or on a stand thanks to the 35 mm StageLok pole socket.

I ordered this sound system because I had used its big sister the 600BT a lot but the prices started to soar. The 400 version is more than enough for our use. I sound the band for small rooms (2 vocal microphones, 2 acoustic guitars, 1 electric).
It is easy to use and easy to transport. I will then add a speaker to return to the monitoring channel.Automatically translated
