Designed by YOGIPRO, a premium sub-brand of ATI Pro Technologies, this amplifier is built for sound engineers, DJs and event organizers who demand both high performance and reliability.
Massive Power for Any Venue
The YJ-4K2HD operates on AC Mains 240V with a power consumption of 5000VA, ensuring a steady power supply for heavy-duty sound systems. It produces 2100W+2100W at 2 Ohms, 1500W+1500W at 4 Ohms and 950W+950W at 8 Ohms. For extreme performance, the 4 Ohm bridge mode delivers an impressive 4200W, making it capable of powering massive speaker arrays with ease.
Exceptional Audio Clarity and Range
With a Total Harmonic Distortion (THD) of just 0.9%, this amplifier ensures clean, distortion-free sound, whether at whisper levels or full output. Its 20Hz–20,000Hz frequency response covers the complete audible spectrum, while the signal-to-noise ratio of 90dB guarantees crystal-clear audio. The input sensitivity of 1V–1.2V (unbalanced) and input impedance of 10k make it compatible with a variety of professional audio devices. A 100Hz low pass filter further refines bass output for a tight and punchy low end.
Professional Connectivity and Control
The YJ-4K2HD offers two male and two female XLR input connections, ensuring flexible integration into any setup. Its two 4-way Speakon and terminal outputs provide secure and efficient speaker connections. The front panel features two 41-step level controls for precise volume adjustment, giving sound engineers total control over the mix.
Built for Reliability on Stage
Equipped with two fixed-speed cooling fans, the YJ-4K2HD maintains optimal performance even during long hours of operation. Safety is a top priority, with temperature, DC and short-circuit protection to safeguard the amplifier and connected equipment. Its damping factor of 400:1 (8 Ohm) ensures deep, controlled bass that makes an impact in large venues.
Conclusion
The YOGIPRO YJ-4K2HD Amplifier is a true powerhouse, delivering precision sound, exceptional power and rock-solid reliability. Whether for a concert stage, outdoor event, or large indoor venue, this amplifier ensures your sound system performs at its absolute best.
