Product Description

The Yamaha Stagepas 400BT Portable PA System is the perfect speaker rig for producing excellent sound on the go, especially when quick and uncomplicated setups are necessary. Featuring 2 powerful speakers and an 8-channel mixer, this simple sound system is ideal for smaller and medium-sized venues, delivering pro-quality sound at high volumes.

Ergonomic Design

With cutting-edge ergonomic design in mind, the 2 speakers don't just deliver great audio, but also serve a secondary purpose as storage units. Whilst one speaker can neatly store cables and smaller accessories, the other speaker houses the detachable mixer. This not only makes travelling very easy, but also ensures that pack downs at gigs are a total breeze.

No-Frills Mixer

If you're new to live sound, the Yamaha Stagepas' 8-channel mixer has a very easy-to-use layout; far less intimidating to navigate compared to others. A 2-band EQ for each channel offers enough tweakability to enhance your sounds, and with 4 built-in reverb types, you can add beautiful depth to vocals or instruments if you're playing in a dry room.

It doesn't end there though, as there is also a master EQ control that can let you optimise the speakers for speech or performances specifically. Turn this up all the way to boost bass frequencies, if you're intending to play dance music or similar styles.

Other Features   

Like many modern PA systems, the Yamaha Stagepas features Bluetooth connectivity, allowing you to stream music from a compatible device within a 10m range. A built-in feedback suppressor is another stellar feature that you'd normally only see on more high-end systems. Via just a single button, you can eliminate unwanted feedback to make sure that your sound is uninterrupted from ear-splitting frequencies.

Mr Darren Velvick14th Feb 2024

Yamaha stages 400bt only used a couple of times so far. Really easy to set up. Sound quality is very good. The only thing is it doesn't come with a bag or dust covers. Which for the price I'm sure they could include this in their products. But all in all I'm impressed so far

Mr Trevor Llewellyn31st Jul 2023

Great PA for small venues. Robust equipment with superb sound quality. Blue tooth connection is very useful. Very neat how the mixer clips into the back of one speaker and the speaker and power cables fit into the conpartrment at the back of the other speaker. Truly portable, just have to carry the two speakers, and they are not too heavy compared to the bigger model Stagepas 600
