【ZERO4 High-End AB-Class 4-Channel Power Amplifier】

The ZERO4 High-End AB-Class 4-Channel Amplifier is for anyone who wants to further refine their car audio sound with greater solidity.

With a 4-channel configuration, this is an easy-to-use model for driving front and rear speakers together, or for applying different channel usage depending on your system setup. Using a Full MOSFET circuit, it’s well-suited to building a system where you can more easily feel the change in sound that comes from adding an amplifier—not just louder music.

The input supports Hi/Lo input switching. Because you can consider the connection method according to the vehicle’s system configuration, it’s an amplifier that makes it easy to propose solutions tailored to your car—from improving sound quality based on the factory audio to systems that combine external devices.

It also includes Highpass/Lowpass band switches, allowing you to make basic adjustments to match the speakers you connect and the overall system configuration. Equipped with a power supply voltage stabilizing regulator as well, it’s recommended for those who want to think beyond choosing the amplifier on its own, and instead use it while considering combinations with speakers and a subwoofer.

LED lighting is standard on the side panel. This model offers not only audio-focused functionality, but also a sense of presence when you look at the amplifier after installation.

An amplifier won’t produce the same results just by being installed. Your impression will change depending on the power supply and grounding, wiring handling, combinations with other devices, and the final sound tuning. At LOGON, we work with you to decide where to incorporate the ZERO4, while confirming your vehicle model, your current system, the music you normally listen to, and the sound you want to achieve.
