Hybrid Voltage Architecture
Fortunately, you can finally say goodbye to bulky and expensive external transformers. This is because the LiYA 425 features a hybrid architecture that smoothly drives traditional low-impedance setups (250W x 4 RMS @ 8 ohms). In addition, it simultaneously powers long-distance commercial configurations (250W x 4 RMS @ 70V/100V). Therefore, this exceptional flexibility ensures that your local or multi-room speaker systems receive consistent, crystal-clear power regardless of how you lay them out. Moreover, switching between these voltage modes is entirely seamless, which simplifies your system tuning during installation.
Advanced Connectivity & Custom Integration
In order to simplify your installation, we designed the LiYA 425 with effortless system integration in mind. For example, the robust back panel accommodates a comprehensive array of digital and analog inputs. Specifically, you can easily connect your source components using RCA, 3-pole Euroblock, Optical, or USB options.
Meanwhile, secure Euroblock terminal blocks manage the speaker outputs to guarantee a stable, signal-loss-free connection. Because it maintains an excellent Signal-to-Noise Ratio (SNR) of ≥ 92dB along with minimal Total Harmonic Distortion (< 0.1%), your background music and announcements will always remain immaculate. Ultimately, this means your audio stays pristine even at high volume thresholds.
