MPro 400 specifications

The JBL MPro 400 is a compact and versatile portable PA speaker designed to cater to a variety of audio needs. A part of JBL’s professional series, the MPro 400 stands out for its robust construction, exceptional sound quality, and innovative features that make it suitable for both mobile performers and fixed installations.

One of the key characteristics of the JBL MPro 400 is its high-performance woofer, which delivers powerful low frequencies, while the accompanying compression driver provides crystal-clear high frequencies. This combination ensures that whether users are delivering speeches, playing music, or engaging in live performances, the sound is balanced and rich. The speaker has a frequency response that spans from 55 Hz to 20 kHz, enabling it to reproduce a wide range of audio content effectively.

The construction of the MPro 400 is another impressive feature. It is housed in a rugged, multi-ply hardwood enclosure that not only enhances durability but also minimizes unwanted resonance. This quality construction makes the speaker suitable for outdoor events and harsh environments. The cabinet design includes integrated handles that make transportation easy, while the built-in pole mount allows for various setup configurations.

Technology-wise, JBL has incorporated a passive crossover system in the MPro 400, helping to ensure that audio signals are effectively directed to the appropriate driver. This results in better overall sound clarity and definition, crucial for performances that require precise sound reproduction.

The speaker also comes equipped with multiple input options, including standard XLR and TRS jacks, making it compatible with a variety of audio sources, from mixers to musical instruments. The MPro 400 is designed for flexibility, catering to performers, DJs, and even as part of a larger PA system.

Additionally, the MPro 400 is designed with thermal protection, which helps prevent damage from overheating during extended use. This feature ensures that users can rely on consistent performance, regardless of the duration or intensity of their events.

In summary, the JBL MPro 400 is an exceptional portable PA system that combines durability, sound quality, and user-friendly features, making it an ideal choice for audio professionals and enthusiasts alike. Whether used in small venues, outdoor events, or as part of a larger sound setup, the MPro 400 promises performance that meets the highest professional standards.
