The E3 P-4.12 power amplifier is a professional 4-channel power amplifier designed for commercial karaoke systems, stages, auditoriums, and event sound systems. The device boasts powerful amplification capabilities, stable operation, and meets the demands of continuous, high-intensity use.

Introducing the E3 P-4.12 Power Amplifier

The E3 P-4.12 power amplifier boasts a power output of 4 x 1200W at 8Ω, 4 ​​x 2400W at 4Ω, and 2 x 3500W in Bridge mode at 8Ω, making it easy to pair with a wide range of karaoke speakers, full-range speakers, and high-power subwoofers. The device has a frequency response of 20Hz – 20kHz (±0.1/0.3dB), delivering balanced, detailed, and accurate sound reproduction across the entire frequency range.

Technical parameters of the product to consider:

• Power output: 4 × 1200W at 8Ω The 4-channel design with high power output allows the E3 P-4.12 to easily drive multiple karaoke speakers or full-range speakers simultaneously while maintaining stable performance.
• Power output: 4 × 2400W at 4Ω When operating at 4Ω impedance, the device significantly increases its amplification capability, making it suitable for high-power sound systems and multiple speaker clusters.
• Bridge power output: 2 x 3500W at 8Ω Bridge mode provides a very high power output to drive subwoofers or high-power speaker systems, making it well-suited for stage and auditorium use.
• Frequency response 20Hz – 20kHz (±0.1/0.3dB): The wide frequency range and minimal error rate allow the device to fully reproduce the entire sound spectrum, from deep bass to bright treble, resulting in a realistic and balanced sound.
• Total harmonic distortion (THD+N) <0,05%: The very low distortion index ensures a clean output signal, minimizing distortion even when the device is operating at high power.
• Intermodulation distortion (IMD): Reducing the overlap between audio signals helps to reproduce vocals and instruments more clearly and distinctly.
• Signal-to-noise ratio (SNR) >100dB: A high SNR (Surface Noise Reduction) helps reduce background noise, resulting in clear, clean sound and preserving more detail in the music.
• Damping Factor: 200:1 This increases the ability to control the speaker diaphragm's movement, resulting in a tighter, more compact bass sound and reducing muddiness or trailing distortion.
• Response speed (Slew Rate) 70V/µs: The device responds quickly to high-intensity or fast-paced audio signals, resulting in accurate and energetic sound.
• Input impedance 20kΩ (Balanced) and 10kΩ (Unbalanced): Ensures compatibility with various devices such as digital sound processors, mixers, and signal processors while maintaining signal stability.
• XLR and TRS connectors: It allows for flexible connection with professional audio sources and equipment, while minimizing signal loss.
• Dedicated speaker terminal output: Provides stable power transmission and a secure connection to the speaker system.
• Cooling by airflow from front to back: It improves heat dissipation efficiency, maintaining a stable temperature during continuous operation, especially at high power levels.
• Multi-layer protection: With integrated Soft Start, DC protection, short-circuit protection, overload protection, clip limit protection, over-temperature protection, and gradual volume increase upon startup, this helps protect the amplifier and the entire speaker system from unforeseen incidents.
• Supports Stereo, Parallel, and Bridge modes: It allows users to flexibly choose the operating mode that best suits their audio configuration.
• Integrated HPF, LPF, input sensitivity adjustment, and Ground Lift: It optimizes signal transmission, reduces noise, minimizes feedback and whistling, and enhances compatibility with various professional audio systems.
