More info

Here is the ALLO PIANO 2.1 HIFI DAC , a converter using 2 DAC PCM5142 with integrated DSP and processing signals up to 32Bit / 384kHz . The circuit is designed and programmed in mode 2.1, with the possibility of connecting a subwoofer. It is part of the range operating with the ALLO Sparky SBC universe .

The digital part and the analog part have been properly separated. The analog side uses an LDO LT3042 with an ultra low noise and a very high PSRR. Specifically, each circuit has 4 LDOs (2 per DAC).

It is directly compatible with the ALLO VOLT AMP amplifier . These two devices are compatible with the SBC ALLO Sparky or the Raspberry Pi 2 and Pi 3. You can therefore use the DAC PIANO 2.1 HIFI on Raspberry Pi 2 and Pi 3.
In case you want to use it on a Raspberry Pi, remember to switch the button on the PCB (RPI COMPATABILITY) to "ON".

The output of the Subwoofer is adjustable from 60 to 200Hz, only on Max 2 Play .

Hello! Today I received Allo Piano 2.1. I checked it on Moodeaudio and piCorePlayer everything works. Fast delivery, good packaging. I buy from you a second time. There was a choice to buy from the site Allo, but I chose you. Thanks for the discount coupon and plastic racks. Next purchase will be KALI I2S RECLOCKER but later. Thanks for your work! Sorry for my English, I use Google translator.
