WONDOM JAB6 Class D digital amplifier, supports I2S lossless cascading, easily build a high-power 4.2 multi-channel audio system
The all-new WONDOM JAB6 (AA-JA33288) is officially open for pre-order!
This Class D amplifier, equipped with dual TPA3255 chips, delivers 4×300W from a single unit, supports multiple output modes including 4.0/2.1/2.0, and adopts a PFFB post-filter feedback circuit to restore delicate sound details with low distortion.
Its modular design is the core highlight: the Bluetooth and DSP input modules can be individually replaced and upgraded without replacing the entire amplifier, offering stronger expandability; it has a built-in ADAU1701 DSP and supports SigmaStudio tuning.
We tested two JAB6 units cascaded through I2S input and output to build a 4.2-channel audio system, with 4 full-range speakers + 2 subwoofers, and lossless digital signal transmission.
Suitable for professional audiovisual customization, commercial audio engineering, high-end Hi-Fi, and multimedia audio projects, supports PC-based debugging, and comes with a full set of safety protections and FCC/CE certification.
Audio integrators and solution providers are welcome to inquire about customized audio solutions.
