Connectivity
EL DAC II accepts three methods of digital input:
| USB | 16/44.1k thru 32/384kHz** |
|---|---|
| Coaxial S/PDIF | 16/8kHz thru 24/192kHz* |
| TOSLINK | 16/8kHz thru 24/192kHz* |
The maximum RCA Output voltage is 2.0VRMS
- Many coax and optical sources are unable to reliably transmit at 192kHz.
** Windows 7 supports 24/192kHz maximum.
Listening Tips
For maximum signal fidelity, set the DAC to at least 24-bit audio and adjust
digital volume slightly below 100% at your computer. Only control volume from
your amplifier.
Listen safely to conserve your hearing: www.hearingloss.org
To ensure an optimal noise floor, always position audio equipment as far away
as possible from wireless devices.
Operating Care
Use gentle force when touching the mode button, and when inserting or removing cables. Set the sampling rate to the highest integer multiple of your music collection. For example, use 176.4kHz for a collection of 44.1k or 88.2k or 176.4kHz files. Use 192kHz for a collection of 48k or 96k or 192k audio files. Alternatively, you may install the optional XMOS drivers in Win10 for exclusive WASAPI mode. EL DAC automatically selects an appropriate sampling rate in coaxial or optical modes.
Computer Setup
EL DAC II requires no drivers in Windows 10, Mac OS, Linux, and modern versions of iOS and Android. You may download drivers for Win7/8 from jdslabs.com/drivers. These drivers may optionally be installed in Win10 for WASAPI support. Be sure to select your new DAC as the default playback device:
Windows 7/8/10
Right-click the volume icon in your taskbar and choose Sound –> Playback.
Click the XMOS or JDS Labs audio device, then choose “Set Default”. For best
experience, also configure Properties:
• Enhancements: Check “Disable all enhancements”
• Advanced: See Listening Tips
Mac OS X
Ensure JDS Labs audio device is selected from Audio Devices.
Troubleshooting
No USB device or “Failed to Play Audio”
Cause: USB Device is not initialized. Solution: Tap the mode button 3x to
cycle through all modes and reset the USB device.
No sound in one channel
Cause: Bad cable, or incorrect computer settings.
Solution: Check balance settings; try another headphone or RCA cable.
Some Mac OS X systems will pan audio to the Left channel upon initial
connection of a DAC. User must restore balance to the center.
Audio is muted after resuming from sleep or hibernating in Windows 10
Cause: Microsoft USB Audio 2.0 driver bug.
Solution: Install XMOS drivers, as per page 5.
POWER ADAPTERS
ATTENTION: Incorrect power adapters can result in capacitor explosion hazards and device damage. Only use the power adapter included with your EL DAC:
| Type: AC-to-AC Transformer | Output Voltage: 15-16 VAC |
|---|---|
| Current: Minimum 500mA | Connector: 2.1×55.mm (ID x OD) |
