Features The e28 DAC is based on the ES9018 Sabre32 reference DAC chip. It delivers 32-bit precision capable of resolving the smallest signal details. The chip features patented 32-bit Hyperstream™ architecture and Time Domain Jitter Eliminator. ES9018 delivers the industry’s highest performance levels that will satisfy the most demanding audio enthusiasts. Mac OS X High-Performance Driver We offer a custom high-performance OS X driver supporting standard PCM sampling rates from 44.
Connecting and Powering the e28 DAC Before connecting, turn off the power to all the components in your system. Connecting the Digital Inputs All digital inputs are galvanically isolated to eliminate ground loop noise. The e28 DAC accepts three digital inputs • USB - This is the recommended and most capable input. It supports 2 to 8 channels PCM and DSD. PCM is supported with 32 bit resolution at standard sampling frequencies from 44.1 kHz to 384 kHz. DSD sampling rates range from 2.8224 MHz to 12.288.
Avoid connecting the e28 DAC to receivers and any other sound processing equipment that performs analogue to digital (ADC) conversion. Digitizing the analogue output signals back to the digital domain for processing will undo the benefits that e28 brings to you. Remember that your sound system is as good as the weakest link in the sound processing chain. Analogue Interconnect Recommendations Over-engineered interconnects made from exotic materials are unnecessary.
Isolating the Cable TV Ground If you have a cable TV connected to your audio system, ensure that the TV cable ground is galvanically isolated from the audio system ground. The TV cable ground, usually connected to the earth outside your home, can have a significantly different potential than the audio ground. This condition can cause audible hum. If you suspect this is the case, use a cable TV ground isolator just before the cable set-top box or at the RF TV input.
Remote Control Setup The e28 DAC is pre-programmed to work with the supplied remote control. If you like, you can reprogram the e28 DAC to work with a different IR remote control. The exaSound e28 DAC can be trained to recognise commands from most infrared remote controls using Sony and NEC IR protocols. Use the following procedure to change remote control button assignments or to pair the e28 DAC with a different remote control: 1. Power on the e28 DAC. Make sure that the unit is not in playback mode. 2.
Setup of exaSound e28 Driver and Dashboard for OS X System Requirements Operating System OS X Mavericks OS X Yosemite Recommended CPU for operating at 352.8 and 384 kHz 2.4GHz dual-core Intel i7 or better Disk Space 10 GB - mainly for music files Software Installation 1. Don’t connect the e28 DAC to your Mac until the driver is installed. Don’t worry if you’ve connected the device already. Just disconnect it. 2. You should have received an email from us with username and password.
4. Locate the exaSound Dashboard icon on the menu bar. The red exclamation mark indicates that the USB cable is disconnected: 5. Connect the USB cable of the exaSound DAC. The red exclamation mark should disappear from the exaSound Dashboard icon. 6. Power on the DAC. The red square overlay on the exaSound Dashboard icon indicates that the device is On and in Stop mode. During playback the red square changed to a green triangle. 7.
9. Make the exaSound driver the default sound output device. 10. Make sure that the volume is set to less than -25db. At this point you can play some music with iTunes. Note: Configuration instructions for Audirvana Plus and JRiver are available on the exaSound Blog: http://www.exasound.com/Blog/tabid/74/articleType/CategoryView/categoryId/10/Guides.aspx.
Using the e28 DAC Using the Asynchronous USB Input Before turning your amplifiers ON, always check the e28 DAC front panel to make sure that the volume level is below -25dB. Please follow the safety measures below strictly. It is quite common to set the volume on your portable Mac to maximum. You should never do this when your e28 DAC is connected to powerful amplifiers and speakers. Playing music or sound effects at maximum level is dangerous for your health and may damage your equipment.
Power On/Off • • The e28 DAC has an automatic power-on function and it will turn itself on when playback is detected. The e28 DAC automatically turns itself off after a period of inactivity. Use the Power Off Timeout setting to adjust the inactivity time interval before shutdown. Volume Control The e28 DAC volume is controlled by the ES9018 DAC chip. It is independent from the Mac software volume control and it preserves the maximum possible signal to noise ratio. The volume level changes in steps of 0.
Settings Menu • • • Click on the exaSound icon on the Menu and select Settings. Use the Max Volume setting to prevent accidental playback at volume levels that are too loud. The e28 DAC automatically turns itself off after a period of inactivity. Use the Power Off Timeout setting to adjust the time interval before shutdown. Settings changes may not come into effect until playback is restarted. Using the exaSound ASIO Drivers for OS X Make sure that the player is configured for ASIO output.
Playing Music from SPDIF Sources The e28 DAC can improve the sonic clarity and fidelity from stereo SPDIF sources. The sound improvement is the result of outstanding jitter cancelling capability, superb signal to noise ratio and low distortion levels of the e28 DAC. You can connect up to two SPDIF devices, such as disk players and wireless music servers. To use SPDIF sources 1.
