D3 TPA3255 300W Audio Power Amplifier HIFI Class D Stereo Sound Bluetooth Aptx True Amp Bass Treble For Home Theater



Description:

O-NOORUS D3 is a Bluetooth 5.0 audio amplifier for passive speakers that features a stereo 300 watt x2 power output. D3 is a 2.1 channel power DAC amplifier which is equipped with Bluetooth, USB, coaxial, optical, and 3.5mm aux input. Volume/input/treble/bass/color/brightness are controlled by remote control or knob.


D3 introduction:

• The D3 is a powerful and extremely compact Class D amplifier. Integrates five kinds of input, bluetooth, USB, optical fiber, coaxial, AUX.
• Active subwoofer output that can be used to create a 2.1 channel Hi-Fi installation. Its subwoofer output makes it the ideal amplifier for users looking for deep, powerful bass, whether for a music listening experience or a 2.1 channel Hi-Fi TV
• The advantage of this amplifier is to provide USB-C input with Realtek ALC4050 audio driver, support OTG audio, 32bit 384Khz.
• Bluetooth, coaxial and optical fiber signals are converted and output by CS8422 to D/A ES9023P for decoding.
• The NJW1194 chip not only controls the output volume, but also controls the gain within +/-10db range of treble and bass.
• The Qualcomm 32-bit QCC3034 Bluetooth receiver chip lets you use multiple audio sources wirelessly and utilizes high-definition Bluetooth transmission codecs such as aptX and aptX HD.
• Overall, this ultra-compact amp focuses on the essentials and delivers great performance at an affordable price.

• Power Supply: 36V/5A

I strongly doubt the 2x300 Watts in 4 Ohm...

 

[TonyJZX]

the dac isnt bad but its over a decade old and as a result is only 24/192

so having a 32/384 usb input is kind of a waste

its one of those things where they try to make it do too much but it does nothing well

probably better off with a dac and whatever is coming from fosi after october

 

[Alexander Lin]

I saw that the USB is an analog output and goes directly to the NJW1194 without going through the DAC.

Nothing new, they all publish specs like this.

I found it kind of useful, the dac chip used is good enough for the amplification.
Don't think there is any use of SOTA dac with TPA3255 amp.

This should only be available with a 50V power supply.

This should only be available with a 50V power supply.

I know how to calculate that

Interesting alternative for the day my loxjie a30 dies. And cheaper! I wish it is a decent one.
Audiophonics has different power specs:

It is TPA3255 based amplifier based on details, and different psu can provide deferent output.
There are no internal pics available yet, but it comes with 32v 5a psu.

Confusing use of red and white RCAs - I assumed they were line in until I opened the pic. As usual overblown power output claims, and no details of how the sub out works. It will be interesting to see how it actually performs.

Looks like a Topping MX3s copy, sans the headphone amp and more power yet not as clean

I expect this one to have more power output than MX3s. Don't know if it can match Aiyima/Fosi 3255 amps performance.

As usual we should have measurements, don't quite trust the brands and their numbers, especially not the 2x300w number

You are correct, but I wasn’t referring to 300W.
We have several 3255 amps measured, that can give fair idea.

 

[gnat_leader]

well more importantly... how the heck does it sound?

 

[Zek]

Has anyone already acquired a D3, and how is the USB input implemented?

I am am just looking to get internal pics first before hitting buy button, want make sure that its not like those 30$ board type.

The USB output is an analog signal, directed to the NJW1194.
