8. Advanced Notes

Proper Digital Audio cables should be used for SPDIF and AES/EBU: Avoid using standard analog audio cables for digital signal. Even though they might look the same, they are not designed for digital audio and performance will be compromised.

• AES/EBU use 110Ω shielded twisted-pair digital cables.
• SPDIF use 75 Ω coaxial (video) cables.
• WC uses 75 Ω BNC cables. And please do not exceed 6 meters in length.

As for Analog Cables, please use:

• Standard high quality cables with XLR connectors;
• Standard high quality cables with TRS connectors.

Connectivity Chart: See 'pull out' page included with this manual.

9. Ground Loop Hum and Noise

The design of Eclipse 384 minimizes the possibility of ground loop hum and noise. However, we recommend the use of short cables and balanced connections for all the audio signals of your system. All power cables of the system should be connected to a dedicated outlet box or power conditioner unit to avoid ground current noise affecting the audio signal path. It's also advisable to keep signal and power cables separate.

10. Additional Information

Additional information regarding operating systems, audio software and media players will be updated through the support area at www.antelopeaudio.com
