NEC (National Electrical Code) Standards

A Note for the Cable Television (CATV) Installer

This reminder is to call the CATV system installer's attention to Article 820-40 of the NEC that provides guidelines for proper grounding and in particular, specifies that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical.

Antenna Grounding Outside the House

If an outside antenna is connected to the receiver, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code,

ANSI/NFPA 70, provides information with regard to proper grounding of the lead-in wire to an antennadischarge unit, connection to grounding electrodes, and requirements for the grounding electrode.

Cable TV Coaxial Cable, Satellite Dish Cables and Television Antennas should be grounded BEFORE the point of entry into the house.

Always observe proper antenna or satellite dish grounding techniques. When lightning strikes there is always the possibility that your antenna or dish (mounted high on the roof) can become a conduit for lightning and electrically damage any equipment to which it is connected. Additionally, proper grounding offers safety to the people using the audio/video system in the event of an electrical problem.

Troubleshooting Guide

The Emotiva XDA-1 DAC preamplifier is expertly designed and built to provide years of trouble-free performance. Most problems that occur can usually be solved by checking your connections or making sure that the audio components connected to the XDA-1 are on and fully operational. The following information will help you deal with common problems you may experience during initial use of your unit. If problems persist, contact Emotiva’s service department for assistance.

No Sound (from one or more full range speakers)

• Speaker cables may have come undone from the amplifier. Turn off your system and check the speaker cables, and tighten the binding posts.

• Audio output cables that connect XDA-1 to the amplifier(s) may not have a good connection. Turn off your system and check all audio cable connections.

• An audio cable may have an internal break. Switch cable with a different channel to see if the problem migrates to a different channel or stays in the affected channel(s).

• The correct input is not currently selected.

• The mute switch is on.

• Switch to a different source and see if Audio is present

No Sound from the AES/EBU Input

• Make sure that the AES/EBU cable is not damaged.

• Make sure that the AES/EBU source is outputting sound properly

• Make sure that the XDA-1’s AES/EBU input is selected.

No Sound from the USB Input

• Make sure that the USB cable is not damaged.

• Make sure that the XDA drivers are properly installed.

• Make sure that the XDA-1 is selected as the output device in your PC.

No Sound from the Optical Input

• Make sure that the OPTICAL cables are not damaged.

• Make sure that the source device is working properly and outputting Audio. Properly

• Switch to a different Optical input to make sure there is Audio present.

No Audio from the Coax input

• Make sure that the coax cable is not damaged.

• Make sure that the source device is working properly and outputting Audio. Properly

• Switch to a different coax input to make sure there is Audio present.

Remote Control Not Working

• Make sure the AAA batteries are not dead or installed incorrectly.

• Make sure that the XDA-1 front panel receiver window is not obstructed.

14

Remotely Connected External Amplifier(s) Do Not Turn Off with XDA-1

Check the following:

• Make sure the 1/8” plug is connected between the XDA-1 trigger output and the amplifier(s) trigger input(s).

• Make sure the total consumption of the connected devices do not exceed 500mA

• If you have spliced the plug to one or more amplifier turn on inputs, remember the center pin is positive and the outer shield is negative. This output is 5 to 12VDC.

“Hum” Noises

• This problem is more than likely caused by a “ground loop” in your system, rather than a fault in the

XDA-1. Follow these steps to isolate the main cause of the hum; there may even be more than one.

Remember to turn off all components in your system (including the XDA-1) before disconnecting or connecting any cables.

Disconnect the following items in order, and check each time if the hum has gone away:

• Disconnect all cables which come from outside the room, such as cable TV, satellite TV, or roof top antennas. Make sure that they are disconnected where they first enter the room, so they are making no connection to the XDA-1, the TV, or any other component. If the hum is caused by the cable TV line, you will need a “ground loop isolator.” This is an inexpensive device fitted in-line with the coaxial cable feed. Contact your cable company or your Emotiva Dealer for assistance.

• Disconnect any component which has a grounded power cord.

• If the hum persists, disconnect all the source components one at a time from the back of the XDA-1 until you identify the problem. (Ground loop isolators are available for audio lines and video. Ask

Emotiva for assistance)

• Try moving the speaker cables away from any power cords. Try just one speaker, connecting it to different channels and see if an amplifier channel is bad.

• If you are still having a problem, remember that Emotiva’s technical support staff will assist you.
