The Yamaha STAGEPAS 400BT is a versatile and portable PA system designed for musicians, performers, and event organizers who need a powerful yet easy-to-use sound solution. This compact system includes two high-quality speakers and a detachable 8-channel mixer, delivering a total of 400 watts of power (200 watts per speaker). With Bluetooth connectivity, it allows for wireless audio streaming, making it suitable for modern needs where streaming from mobile devices is a common requirement.

Each of the two speakers in the STAGEPAS 400BT setup features an 8-inch low-frequency woofer and a 1-inch high-frequency compression driver. The speakers are designed for optimal sound clarity and bass response, providing a frequency range from 55 Hz to 20 kHz. They are built with a bass reflex design to enhance the low-end output, and their compact size makes them easy to transport to any venue. Each speaker comes equipped with a built-in carrying handle and a 35 mm pole socket, enabling secure mounting on speaker stands.

The 8-channel mixer is a standout feature, offering flexibility in managing different audio inputs. It includes four mono channels that can accept both microphone and line inputs, making it ideal for vocalists, instruments, and even direct connections from electric guitars. Additionally, the mixer has two stereo line input channels, which can be used for various audio sources such as keyboards, DJ gear, or media players. The mixer is designed to attach to the back of one of the speakers for ease of transport, but can also be placed separately for quick adjustments during performances.

A unique aspect of the STAGEPAS 400BT is its built-in SPX digital reverb, which offers four types of reverb effects—Hall, Plate, Room, and Echo. These effects can be easily adjusted through the mixer, allowing performers to add depth and ambiance to their sound. This feature, combined with a one-knob master EQ, enables users to tailor their sound for different settings, whether it’s a small room or a larger outdoor venue. The master EQ can be adjusted to optimize settings for speech or music, and a bass boost option is available for those who want a richer low-end sound.

The Bluetooth functionality is particularly convenient for modern users, allowing seamless streaming of music or backing tracks directly to the PA system without the need for cables. This makes it ideal for DJs, solo performers, and those who need to play pre-recorded audio during events. It also supports a variety of input types, including RCA and 3.5 mm aux inputs, ensuring compatibility with different audio sources.

An important feature for live performances is the onboard feedback suppressor, which helps to minimize the risk of unwanted noise and squealing during events. This feature is particularly useful in live settings where feedback can be a common issue. The feedback suppressor automatically detects and reduces frequencies that cause feedback, providing a smoother audio experience for both the audience and the performer.

In terms of build and portability, the entire system, including the mixer and speakers, is lightweight and easy to carry, with a total weight of around 18 kilograms. This makes it suitable for mobile setups where quick assembly and breakdown are essential. The design allows performers to transport the system easily between gigs or set up at various event venues without needing extensive technical knowledge.

The Yamaha STAGEPAS 400BT also offers expandability, allowing users to connect additional equipment such as subwoofers or external monitors through its line outputs. This capability makes it a future-proof investment for those who may want to grow their audio setup as their needs change. The system’s durable construction and built-in limiter circuit help protect against speaker overload, ensuring reliable performance over time.

Overall, the Yamaha STAGEPAS 400BT is a robust, user-friendly PA system that caters to a range of needs, from small live performances to corporate events and presentations. Its combination of power, portability, and ease of use makes it an excellent choice for musicians and event organizers looking for a reliable sound solution. With its Bluetooth streaming, high-quality reverb effects, and feedback suppression, it provides the tools needed to deliver a professional audio experience in a variety of settings.
