FDA Amplifier Subwoofer Output TAS5342 2x40W 8 Ohm
With the D502, FX-Audio offers a complete, powerful Full Digital Amplifier (FDA) at a contained price. Equipped with complete connectivity, quality components, a beautiful screen and high / low settings, it will offer a rich and precise sound reproduction.
The amplifier stage of the D502 is based on a high performance TI TAS5342 chip. This allows to deliver 2x40W under 8 Ohm or 2x60W under 4 Ohm while ensuring a low noise and distortion rate. Power that will allow you to combine the amplifier with many speakers, especially since the D502 offers a high efficiency over 90%.
In addition, the chip incorporates a complete protection system protecting the device from short circuits, overloads, undervoltage, excessive temperatures or loss of PWM signal.
The Cirrus Logic CS8422 chip is a 24-bit asynchronous sampling rate converter that also incorporates an SPDIF interface. The CS8422 allows synchronization with the Master Clock for perfect synchronization and therefore an ultra weak jitter.
So that you can connect a USB device like a smartphone for example, the D502 offers a Micro USB input. Behind this plug is a SA9023 USB interface chip, supporting sampling rates up to 24bit 96kHz. A chip that has already proven itself in many audio devices.
The NE5532 is an efficient dual operational amplifier. It offers good performance in terms of noise, high gain, low distortion, high scanning speed and numerous protections. In the case of the D502, this chip handles the subwoofer output.
FX-Audio comes with its FDA IR remote control to control the amplifier and all its features. So, no need to get up to turn on the unit, adjust the volume, change source or adjust the bass and treble.
