Similar to power* soft 90%, using almost exactly the same materials.
The AM3004 is an amplifier module featuring 4 output channel specifically designed for multi-way loudspeakers and asymmetric loads. The highly compact design, integrating all 4 channel and the power supply in a single chassis , makes the AM3004 a unique product. Capable of amazing sonic performance thanks to the 6-layers PCB, the AM3004 features a new power supply design equipped with PFC and featuring smart Rails management , to grant incredible efficiency . It is the most ideal platform for 3-way active systems.
Features
* Power factor correction(PFC): for worldwide operation and error proof connection to mains voltage (up to 400VAC tolerant)

*High efficiency / low consumption universal power supply
* Fixed frequency switch mode output stage for highest grade audio accuracy
* Optional DSP board
* High performances ethernet based digital audio routing and control optional board
* Flexibility: available in "single unit" version to maximize compactness or with separated power supply and amplification stage to ease mechanical integration
* Bypass line outputs for external active/passive filters
* Comprehensive and smart protection features : Thermal , over-current,non audio signals
*Thermal protections (power limiting - thermal shutdown)
* short-circuit/ overload output protection
* Clip limiter
* High frequency protection
* Auxiliary output voltage (+-12V regulated , 500mA max)
* mute command
* Temperature controlled internal Fan and outputs
