Technical parameters of the product to consider:

• Output power: 2 × 1200W (8Ω), 2 × 1800W (4Ω), 3600W (Bridge 8Ω) The KTreasure PE2120 boasts high power output, effectively meeting the amplification needs of karaoke speaker systems, full-range speakers, line array speakers, monitor speakers, and subwoofers. Its 3600W Bridge mode delivers a powerful output, suitable for professional sound systems requiring high performance.
• Signal-to-noise ratio (S/N Ratio): 103dB With a signal-to-noise ratio of 103dB, the device effectively eliminates background noise, resulting in cleaner output sound and preserving the detail of vocals and instruments even in large spaces.
• Signal switching speed (Slew Rate): 80V/μS The high Slew Rate allows the PE2120 to respond quickly to audio signals with constantly changing amplitudes, accurately reproducing drums, guitar, piano, and dynamic sound effects without pulse distortion.
• Damping Factor: 800:1 A very high damping factor helps control the movement of the speaker diaphragm effectively, especially with large-diameter bass speakers. This results in a solid, clean bass sound, reducing muddiness and trailing distortion when operating at high power levels.
• Frequency response: 20Hz – 20kHz (±0.2dB) This device reproduces the full range of human hearing with extremely low distortion, delivering balanced, accurate sound quality from deep bass to clear treble.
• Total Harmonic Distortion (THD): ≤0.01% @ Rated Power, 8Ω, 1kHz Ultra-low THD (Thunder High Dynamic Range) ensures accurate amplification of audio signals, minimizing distortion at high power levels, resulting in clean, clear sound and preserving the original recording quality.
• Intermodulation distortion (TIM): ≤0.01% @ Rated Power, 8Ω This parameter indicates excellent ability to handle complex audio signals, preventing overlapping frequency ranges and preserving detail in music with many instruments or vocals.
• Input sensitivity: 1.66V, 1.4V, 1V, 0.775V The PE2120 supports multiple input sensitivity levels, making it easy to pair with various sources and signal processing equipment such as DSPs, mixers, equalizers, and professional audio processors.
• Input impedance: 20KΩ (Balanced), 10KΩ (Unbalanced) The device supports both balanced and unbalanced connections, which helps reduce signal interference during long-distance transmission and ensures compatibility with a wide range of audio systems.
• Interference immunity and channel separation capabilities: With an Input Common Mode Rejection Ratio ≤ -80dB and Channel Separation ≤ -75dB, the PE2120 minimizes interference from the external environment while ensuring independent operation of the left and right channels, delivering clear and accurate stereo sound.
• Comprehensive protection system: The KTreasure PE2120 power amplifier incorporates multiple protection mechanisms such as DC Protection, Overheat Protection, Overcurrent Protection, Peak Limiter (PESK), Soft Start, Startup Delay, and Shock Protection. These features help protect the amplifier and speaker system from electrical problems or overloads during operation.
• Design and size: The device features a standard 2U rackmount design, measuring 483 × 520 × 89mm and weighing 24,4kg, making it suitable for installation in professional audio racks. Its robust design enhances durability and facilitates installation, transportation, and system maintenance.
