Powerful DSP Processing
◎ IIR Filters
Offering a variety of Bessel, Butterworth, Linkwitz-Riley filters, supporting high-pass, low-pass, and parametric equalization, easily achieving -48dB/octave adjustments and phase control.
◎ FIR Filters
Enhancing the impact of audio, ensuring a more dynamic and impactful sound experience. Linear phase response retains the original transient characteristics of the audio signal, resulting in finer and more precise notes.
Perfect Integration of BrainCoreTM Technology
Perfectly integrating BrainCoreTM technology, providing precise digital processing through superior Limita™ processing technology, ensuring the system operates safely and reliably.
High-Efficiency Class D Power Amplifier
The UTA-DSP Series utilizes Class D amplification technology, with an efficiency exceeding 90%, which significantly reduces energy loss during power conversion. This not only decreases heat generation but also lowers energy consumption while maintaining excellent sound quality.
Global Universal Power Supply & PFC Technology
With 100-240V global voltage auto-adaptation and PFC stabilized power supply, it supports plug-and-play functionality, ensuring energy efficiency and stability.
Intelligent Silent Heat Dissipation
Built-in stepless speed regulation fan that adjusts speed automatically, providing quiet and undisturbed operation.
