JBL Revolutionizes Midsize PAs with the JBL PRX ONE


Mobile PAs have some endemic problems—limited inputs and outputs, limited built-in effects, subpar Bluetooth performance, and acoustics that leave a lot to be desired. JBL is hoping to change that with its PRX ONE mobile PA system for midsize live events. With a clear and powerful performance, an extensive seven-channel mixer built in, a full suite of effects from renowned manufacturers, and more, the JBL PRX ONE is sure to be a hit at your next party, wedding, family reunion, or any other event made sweeter by the addition of music or reinforced sound.

The JBL PRX starts with a 2000W clean, Class-D power amp to get things going, one with Power Factor Correction technology to protect against dirty power issues at the venue. From there, the unit offers an array of speakers designed to promote a coherent frequency response from the front of the room to the back of the house. Minimal DSP is used in tuning the speaker—instead, the PRX ONE relies on acoustical design principles to achieve a consistent reverberation time, off-axis response, and less power-compression to boot.

The woofers are nothing to sneeze at either: Improved LF coupling allows the woofers to get lower without working harder to do so, resulting in a clean low end, down to 35 Hz. A quad-port bass reflex design improves the low-frequency response, ensuring bass you can feel as well as hear all around the room.

Extensive I/O is provided by means of the seven-channel mixer, which gives you streamlined rock-solid Bluetooth audio, as well as four XLR jacks, two Hi-Z inputs, and the ability to power condenser mics with phantom power. Two mixer modes are on hand, switchable at the press of a button. Channel Strip Mode lets you control specific channel functions (gain, EQ, etc.), while Mixer Mode is more of a macro approach, letting you control all seven channels, similar to the way you would on a standard mixer.

The mixer also offers triple-tier DSP for onboard mixing. What is triple-tier DSP? Basically, three avenues of approach, each suited for the beginner, intermediate, and advanced user, respectively. No matter your skill level, you’ll be able to get a great sound, using all-star effects from Lexicon and DBX.

That’s just a taste of what the PRX ONE has to offer. What do you think is the most exciting part of this portable PA? Is it any of the features we covered?
