Mercury V3 is now Mercury V3 DAC! Now Includes Built-In Hi-Res Audio DAC!
Mercury V3 DAC FAQQ: Do all Mercury V3 DAC outputs work simultaneously?
A: Yes, all digital and analog audio outputs deliver the same audio data at the same time. This includes the RJ45 I2S and I2S over HDMI. Q: What power supply comes with Mercury V3 DAC? A: Mercury V3 DAC is designed to operate with a nominal input voltage 12V (+/- 10%). We provide a High Quality Meanwell switching power supply. Q: But aren't switching supplies bad ? A: Mercury V3 DAC is designed with a highly effective noise filter on the 12V input. This circuit reduces the input supply noise by a factor of 100! Q: What size is the power jack on Mercury V3 DAC? A: Mercury V3 DAC has a 2.5MM x 5.5MM DC Jack. The Meanwell supply uses 2.1mm. A 2.1mm to 2.5mm Adapter is included and is located in the power supply box. Q: What pinout is supported by the I2S over HDMI? A: Mercury V3 DAC supports the PS Audio and GD-Audio pinouts. The SWAP switch on the back of the unit selects between these two options. Q: What Operating Systems does Mercury V3 DAC support? A: Mercury supports all known Raspberry PI OS's. We provide pre-configured images for Volumio, Ropieee and Moode. Others may be available upon request. Q: Which one should I choose? A: Mercury V3 DAC is offered with one of three OS options: Volumio, Moode Audio and Ropieee. See the descriptions below along with the links to download pre-configured images for Mercury V3 DAC. Other OS's may be available upon request. Note that any Raspberry Pi OS will run on Mercury V3 DAC, but may require configuration to run properly. Contact us if you have questions. Q: Where is the WiFi/Bluetooth antenna? A: The front panel of Mercury V3 DAC is made of black, matte finish acrylic. This material easily passes the RF signals from the internal Raspberry Pi 4 PCB antenna. For greater range an external USB dongle can be used. Q: What is the performance of the DAC ? A: The 24-Bit ES9033Q DAC with built in Line Level (2.1V) drivers offers THD+N of -106dB (20hz - 20Khz) typical and -104dB worst case, SNR is -118dB.
