Home CasaVerdeSmart ,,,,, Avantree DAC01 is a valid ally for anyone who wants to connect an amplifier, DVD player or other audio device to their home television. It is in fact a fundamental accessory as it eliminates any limit related to the compatibility of inputs and outputs: it can in fact convert the coaxial or digital inputs into analog stereo outputs without compromising the final audio quality of the various connected parts.
As did
Constructively, there is little to complain about: it is very compact (8.4 x 6.2 x 2.3 centimeters) and the case is made entirely of brushed metal. Each socket is far from the others and marked by the relative colors and by an indication to recognize it at a glance.
Specifically, on the front side there is the switch to select the coaxial or digital input, the headphone output (3.5mm jack) and the On / Off switch integrated in a volume adjustment knob. On the back there is instead the microUSB input for the power supply, the Optical and Coaxial inputs (yellow) and the analog stereo audio output (red and white).
Before use
It should be noted that the DAC in question only supports PCM / LPCMe audio signals, it does not support Dolby, DTS or other surround signals. It is therefore important that the digital output of the device to which it is connected can be set to PCM / LPCM output in order to avoid device malfunctions.
Technical specifications
Avantree DAC01 can be powered by connecting it to the appropriate 5V power supply included in the package which delivers 1A. If necessary, it can also be connected to the USB output of the TV or to an emergency battery for sporadic use (for example at a garden party to connect the audio system to a projector).
This digital-to-analog converter operates on sample rates: 32KHz, 44.1KHz, 48KHz, 96KHz and 192KHz, up to 24bits.
Examples of use
This device can be used for example to connect a DVD player to the TV. In one of our tests we connected the optical output of the TV to the respective socket on the DAC, the latter (after having previously powered it) then we connected it to the DVD player via the coaxial cable.
On another occasion we made the same optical connection, however, choosing the analog output (white and red) of the DAC to connect an old audio system we had at home. In a third test we also added a headphone by connecting it to the front audio output.
The system works very well. We have never noticed delays or fluctuations in the signal in the transmission, which is always linear and clean. We liked the possibility of being able to use both outputs (white and red and the headphone one in front) to listen to the same audio stream on two different devices, for example by reusing an old stereo system connected to the new TV (with only an optical output) to movies and TV series and occasionally carry the same audio signal even on a wired headset.
Conclusions
It is a robust and practical solution to transform any digital signal into analog (but not vice versa), then to connect Smart TVs or new generation peripherals to audio systems of any kind. We liked it because the converter is very compact and really easy to use, with clear indications for input and output so that we do not allow us to ignore the user manual.
