O-Noorus D3: Class D compact amplifier with Bluetooth launched

O-Noorus D3 is a compact and powerful amplifier with the essentials. The D3 is equipped with a TPA3255 amplification chip and has an output power of 2x130W into 4 ohms. It also features an ES9023P DAC chip, a QCC3034 Bluetooth 5.0 receiver chip, a Realtek ALC4050 interface linked to the USB-C input, and an NJW1194 volume control chip.

This small amplifier is compatible with a wide range of devices and technologies, including smartphones, computers and tablets, Android TVs and game consoles via its USB-C input port. Connectivity options include the essentials: terminals for connecting speakers and a subwoofer output, as well as optical, USB-C and Jack 3.5 mm inputs.

For the D3 amplifier, O-Noorus chose the Qualcomm QCC3034 Bluetooth receiver chip. This allows it to accept a variety of codecs such as SBC, AAC, aptX and aptx HD across numerous audio sources, with the latter two providing high-quality wireless audio.

One of the benefits of this small, powerful amplifier is that it has an RCA subwoofer output, allowing you to use a 2.1-channel audio system for immersive sound.

The USB-C input allows the D3 to support sample rates up to PCM 32bit 384kHz without drivers on Windows 10, Windows 11, MAC and Linux.
