【8chDSPAMP AF C8.14 bit｜14ch DSP control supported・DSP amplifier with built-in 8ch power amplifier】

This is a DSP amplifier suited for those who want to fine-tune their factory audio sound a bit more, and for those who want to evolve their system step by step—such as by replacing speakers or adding a subwoofer.

8chDSPAMP AF C8.14 bit is a model that integrates up to 14ch of DSP control with an 8ch power amplifier. You can drive the speakers properly using the built-in amplifier while adjusting the volume, frequency bands, and interconnection for each speaker in the car in detail.

It’s also easy to use when you want to tune the sound without replacing the factory head unit. The advantage of a DSP amplifier is that you can go beyond what can be adjusted by speaker replacement alone—such as sound imaging, how vocals come through, and the cohesion of the bass and mid/high frequencies.

14ch DSP that lets you craft the sound changes

Supports 24bit / 96kHz operation and a playback bandwidth of up to 40kHz. You can process the input music signal in detail, including high-resolution audio sources.

Because it supports DSP control of up to 14 channels, it’s designed to be well-suited for systems that combine multiple speakers, such as front, rear, center, and subwoofers.

You can power 8ch with the built-in amplifier, and by combining an external power amplifier as well, you can expand the system up to a maximum 14ch output.

Built-in high-efficiency 8ch power amplifier

The built-in power amplifier supports 65W×8ch at 4Ω and 100W×8ch at 2Ω.

Since the DSP and amplifier are integrated, it’s easier to organize the system than when combining a separate processor and a power amplifier. With a high-efficiency Class-D design (81%), it is also designed with consideration for heat generation and power consumption.

Standby current consumption is 1.5mA. Designed to be easy to handle for in-car use, taking pairing with a factory head unit into account.

Even with the same product, the final result changes with installation and adjustment

A DSP amplifier isn’t a product that automatically delivers great sound just by installing it.

You need to check the factory audio configuration and how the speakers are used for each vehicle model, decide how to assign each channel, determine how far the speakers will be driven by the built-in amplifier, and consider whether to add an external amplifier.

In addition, the final ease of use and the cohesion of the sound are determined by everything from cable routing and how the unit is fixed, to how it relates to factory functions, and even the sound tuning after installation.

If it were me, I wouldn’t start with a large system from the beginning. I would first confirm the current speakers and any planned upgrades for the future, then consider a sensible configuration. It’s also realistic to make use of the built-in amplifier first and add an external amplifier only at the stage when it becomes necessary.

Recommended configurations will vary depending on the vehicle model and factory system, the music you want to listen to, and your preferred volume. I think it’s hard to regret choosing the 8chDSPAMP AF C8.14 bit by organizing together what sound changes you want to make with it and how you want to develop the system in the future.
