The SR+ App unleashes the full power of our new generation subwoofers, offering a suite of features designed to elevate your listening experience: Effortless Real-Time Control: Imagine fine-tuning your subwoofer's settings while your music is playing, directly from your listening position. The SR+ App makes this a reality. Witness instant changes to parameters, allowing you to dial in the perfect bass response on the fly. Precision at Your Fingertips: The app bi-directionally communicates with your subwoofer, displaying its exact current settings. Every adjustment made on the touch-controlled screen is precise and immediate, ensuring the purest HiFi integration. Multi-Subwoofer Mastery (SR+ Exclusive): Custom Naming: Easily identify and manage multiple SR+ subwoofers by assigning unique Position Names (e.g., "Front Left," "Rear Right"). Group Control: Assign up to nine distinct groups for your subwoofers. Synchronised Adjustments: Simultaneously mute or unmute individual subwoofers or entire groups. Effortlessly increase or decrease the gain for all subwoofers within a group at the same time. Visualise Your Bass with the Real-Time Analyser (RTA): Even if you don't own an SR+ enabled subwoofer, you can still benefit! The integrated RTA provides a real-time visual representation of the frequency response curve. This powerful tool is invaluable for optimising the integration of any subwoofer with your main speakers in both 2-channel and multi-channel setups. Adjust sensitivity and frequency range settings for a tailored analysis. More Than Just Control – It's About Perfection. The SR+ App builds upon MJ Acoustics' industry-leading feature set, adding these powerful new capabilities to ensure you achieve the most accurate and immersive bass experience possible.
