In the case of the e12 DAC, sound data is requested by the FPGA core and stored in the device FIFO memory buffer. The FPGA core makes sure that the buffer never gets empty during playback. Data from the buffer is streamed to the DAC chip.
USB interface. Hardware Volume Control and Volume Bypass The e12 DAC volume is controlled by the ES9018 DAC chip. It is completely independent from the Windows software volume control. Audio data is always bitstreamed over the USB interface at full scale 0db/32bit resolution.
Connecting the Line Outputs Make sure that your analogue power amplifier is turned off. • RCA Line Outputs - Left / Right - Connect the Left and Right RCA line outputs of the e12 DAC to • the amplifier line inputs.
Using an Upgraded Power Supply The e12 DAC comes with a 12V/1670mA power adapter. This power adapter has been tested to comply with the DAC’s power supply and quality requirements and allows for very high performance. A better unit may allow you to release the last bit of performance from the e12 DAC.
The first step required in the Windows setup process is to install the exaSound ASIO driver: 1. Don’t connect the e12 DAC to the PC until the driver is installed. Don’t worry if you’ve connected the device already. Just disconnect it.
