FX-Audio D502BT

Amplifier FDA TAS5342A Subwoofer Output Bluetooth 5.0 2x40W 8 Ohm Silver

FX-Audio D502BT Amplificateur FDA TAS5342A Sortie Subwoofer Bluetooth 5.0 2x40W 8 Ohm

The FX-Audio D502BT is, as its name suggests, the successor to the D502. The D502BT takes over its base and components, but this time it comes with a Bluetooth 5.0 receiver, which is very useful for remote music playback from a compatible device such as a smartphone.

The D502BT is therefore a complete, high-performance FDA (Full Digital Amplifier) amplifier at a contained price. It is equipped with a complete set of connectors, quality components, a beautiful OLED screen and treble / bass settings, while delivering a rich and precise sound.

An efficient TAS5342 amplifier chip

The amplification stage of the D502BT is entrusted to a high-performance TI TAS5342 chip. This one allows to deliver a power of 2x40W under 8 Ohm or 2x60W under 4 Ohm, while ensuring a low noise and distortion rate. A power which will allow you to associate the amplifier with many loudspeakers, especially since the D502BT offers a high efficiency of more than 90%.

In addition, the chip integrates a complete protection system, protecting the device from short circuits, undervoltage, overtemperature or loss of PWM signal.

Bluetooth 5.0

The great novelty of this D502BT version is of course its Bluetooth reception. For this purpose, it embeds a Qualcomm QCC3003 chip, supporting Bluetooth in version 5.0. This allows a fast and stable transmission of audio streams, for high quality listening.

High precision

Cirrus Logic's CS8422 chip is a 24bit asynchronous sample rate converter that also incorporates an S/PDIF interface. The CS8422 allows synchronization with the Master Clock for perfect synchronization and thus ultra-low jitter.

USB SA9023 Interface

To allow you to connect a USB device such as a smartphone for example, the D502BT offers a USB Micro input. Behind this plug is a SA9023 USB interface chip, supporting sample rates up to 24bit 96kHz. A chip that has already proven itself in many audio devices.

NE5532 Subwoofer Output

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 D502BT, this chip takes care of the subwoofer output.

IR Remote Control

FX-Audio provides an IR remote control with its FDA to control the amplifier and all its functions. No need to get up to turn on the unit, adjust the volume, change sources or adjust bass and treble.

A complete set of connectors

The D502BT, like its predecessor, offers a full range of inputs and outputs to meet the vast majority of needs and allow integration into most audio systems.

Backup for my Advance Paris AMP
Due to some issues with my main AMP (right channel is not working), i just used the FX-AUDIO D502BT as a backup amp for my living room (TV, PC and BT connected).
And what should i say, it is surprisngly good. Not the punch of the Advance amp, but not way behind that.
Perfect and easy to setup for me with the Sub out as well.
Normally i just bypass sound settings or EQ, but in case with the FX-AUDIO D502BT is just set to EQ preset no. 4, this works best for my ears and listening style.

5 stars from my side for price efficient small amp.
