[A5 PRO | 8ch Amplifier Built-in / 16ch DSP Player-Integrated Processor]

Want to fine-tune the sound of your factory audio a bit more, expand your system, and enjoy music from a smartphone or USB memory inside the car? That’s exactly what A5 PRO is for.

A 16ch DSP player-integrated processor that combines playback, DSP control, and amplification in a single unit—featuring an 8ch class-D amplifier built in. It’s designed to be easy to set up, and makes it easier to build a true high-end car audio environment even with limited space in the vehicle.

Easy to Choose Playback Methods, Wide Range of Use

It includes three USB ports and supports high-resolution audio. It also supports Wi-Fi and Bluetooth 5.0, making it easier to choose how to connect to the audio sources and smartphones you use every day.

Bluetooth supports aptX, AAC, and SBC. With RCA input and high-level input as well, the design is flexible enough to support both systems that make use of your factory navigation/factory audio and configurations that combine external devices.

In addition to operation with a wireless remote control, it also supports an optional display-equipped controller. By using the VIDEO OUT terminal, you can even display the track title on a monitor.

DSP That Lets You Fine-Tune the Sound to Fit Your Car

The DSP section uses an Analog Devices chip, and the DAC uses PCM1690. Included software allows detailed adjustment of each channel, such as a 31-band EQ, time alignment, crossover, and phase adjustment.

Car audio can sound different even when using the same equipment, depending on the shape of the cabin, the placement of the speakers, and how it’s combined with the factory system. A5 PRO’s great advantage is that after adding speakers or a subwoofer, you can tune the balance and blending of the sound to match the vehicle.

However, more DSP adjustment items don’t automatically mean better sound. It’s important to check the input signal and speaker characteristics, then adjust according to how you use it and your preferences.

A5 PRO Installation: Plan Including Mounting and Tuning

Because A5 PRO has many features, the overall configuration changes depending on how it’s connected to the vehicle’s factory system and the combination of speakers/subwoofers you use.

At LOGON, we don’t just handle installation of the product by itself. After confirming your current system and how you use the car, we guide you while organizing which features are necessary and which are unnecessary. By considering wiring, installation methods, and even future system upgrades, it’s easier to produce a system that is comfortable to use and easy to tune after installation.

Decide together at the beginning: how far do you want to change the sound with A5 PRO, how much of the factory functions do you want to keep, and whether you plan to add speakers or a subwoofer in the future. Since the recommended configuration varies by vehicle model and current system, if you’re considering installing it, let’s determine the direction while first looking at the condition of your vehicle.
