audio – up to 24-bit/192kHz playback<br>
Audiophile ESS Technology Sabre premier stereo DAC ES9023<br>
ES9023 delivers jitter-free studio quality audio with 112dB DNR<br>
Built in High quality Class-D stereo audio amplifiers (TI TPA3116D2
x2)<br>
Up to 2×100W Into a 4-Ω BTL Load at 21Vdc<br>
Capable of driving 4 Ohm speakers (also works with higher impedance
speakers)<br>
Uses the Texas Instruments ultra-low-noise voltage regulator (output
noise< 10μVRMS)<br>
Uses the Texas Instruments high efficiency step-Down DC converter (up to
95%)<br>
6V~26Vdc converted to 5.1V, 3A to power the Raspberry Pi <br>
Uses the genuine ALPS RK163 series potentiometer for smooth volume
adjustment<br>
Built in high quality IR sensor (Vishay -the world's leading supplier of
infrared receivers)<br>
Onboard 3.5mm stereo headphone jack allowing audio input form other audio
devices<br>
Onboard pluggable speaker & power screw terminals<br>
Onboard PH2.0 connector allowing to connect a lighted power switch<br>
Onboard XH2.54 connector providing 5V output to power other devices<br>
Onboard gold-plated high-current DC power jack (5.5x2.5mm)<br>
Uses the digital I2S audio signals to reduce CPU load over USB audio solutions<br>
Connects directly to the Raspberry Pi - No wiring required<br>
Powers the Raspberry Pi - no additional power supply<br>
Reserved Raspberry Pi GPIO pin header (2x13Pins)<br>
Pop-noise can be improved by enabling GPIO control<br>
AMP can be enabled / disabled with jumper link<br>
Heat-sink attached to amplifiers for perfect heat dissipation</td>

==FAQ==
1. How to use the pin header marked “PWR ON” , “SPK MUTE” and “AMP OFF”?.
* PWR ON: Short - Auto power on when power applied, Open – Using an external latching switch to control power on/off
* SPK MUTE: Short – Speaker un-muted, Open – Mute enabled and it is controlled by GPIO22 with additional software setting e.g high = speaker unmuted, Low=speaker muted
* AMP OFF: Short – speaker in shutdown mode, Open – Speaker in operation mode

==FAQ==
1. How to use the pin header marked “PWR ON” , “SPK MUTE” and “AMP OFF”?.
* PWR ON: Short - Auto power on when power applied, Open – Using an external latching switch to control power on/off
* SPK MUTE: Short – Speaker un-muted, Open – Mute enabled and it is controlled by GPIO22 with additional software setting e.g high = speaker unmuted, Low=speaker muted
* AMP OFF: Short – speaker in shutdown mode, Open – Speaker in operation mode
