The product stands out with its powerful output, stable operation, and easy compatibility with a wide range of speakers.

Introducing the Main E3 PA-4.13

The E3 PA-4.13 power amplifier is a karaoke amplifier configured with 4 independent channels, boasting a high power output of 4 x 1300W at 8Ω and up to 4 x 1900W at 4Ω. This allows the device to easily drive high-power full-range speakers or subwoofers, ensuring powerful, clear, and stable sound.

Additionally, the 8Ω bridge mode delivers 2 × 2600W, providing enhanced power when needed for configurations requiring higher hitting power.

Technical parameters of the product to consider:

• 4-channel configuration: The E3 PA-4.13 boasts four independent channels, allowing users to easily split the signal to power multiple speakers or different areas. This is a significant advantage when used in commercial karaoke rooms or multi-zone sound systems, optimizing costs and reducing the number of devices needed.
• Power output: 4 × 1300W (8Ω) The 1300W per channel power output at 8Ω indicates that this is a high-power amplifier, capable of driving 12-inch full-range speakers, 15-inch bass speakers, or even medium-sized subwoofers. This power ensures that the sound remains powerful and doesn't falter when operating at high intensity.
• Power output: 4 × 1900W (4Ω) When operating at 4Ω impedance, the power output is boosted to 1900W per channel, maximizing the device's performance. This is particularly useful when using low-impedance speakers or when higher power is needed to cover larger spaces.
• Bridge mode 2 × 2600W: Bridge mode allows combining two channels into one, producing up to 2600W of power per channel. This is a suitable option when driving subwoofers or high-power speakers that require strong driving power and high stability.
• Frequency range 20Hz – 20kHz: The wide frequency range allows the device to fully reproduce all sound ranges from bass to treble. This ensures a balanced output sound with solid bass, clear mids, and bright treble, suitable for both karaoke and music listening.
• THD < 0.05%: Low harmonic distortion indicates that the audio signal is amplified accurately without significant distortion. This helps maintain sound fidelity, which is especially important when used at high volume levels.
• Damping Factor 200: Excellent speaker control, tight bass. The high damping coefficient helps the main unit better control the speaker diaphragm, especially in the low frequency range. As a result, the bass becomes solid, tight, and free from trailing effects, providing a clear and decisive sound.
• SNR > 100dB: A high signal-to-noise ratio results in clear output sound, minimizing background noise and interference. This makes listening to music and singing karaoke a clearer and more enjoyable experience.
• Slew Rate 70V/µs: A high response speed allows the main unit to quickly process constantly changing audio signals, especially in fast-paced music. As a result, the sound becomes sharper and more detailed.
• Input impedance 20kΩ: The standard input impedance allows the device to be easily paired with digital processors, mixers, or other audio sources without signal loss.
• AC power supply 220–240V: The device uses a standard power supply, ensuring stable operation under Vietnam's power grid conditions without the need for an additional converter.
