the same time. The DMC-1 will power on and cycle through the display. Keep holding the
buttons down until “Resetting to Factory Defaults” appears in the front panel display. When
the DMC-1 has been reset, it will shut off. Turn the DMC-1 back on and it will go to the default
screen. It has now been reset. If the DMC-1 has to be reset regularly, you should invest in a
good quality AC line conditioner or contact Emotiva for technical support.
Problems Updating DMC-1 Firmware
Check that the serial cable is connected correctly between the DMC-1 and your computer’s
serial port
If you have a Palm Pilot
™
or similar device with “HotSync™” or its equivalent, you may need to
disable this software before proceeding. This software ‘seizes’ control of a serial port on your
machine and prevents the Emotiva software from accessing that port. Use another port or
disable HotSync.
For additional information regarding technical issues encountered with updating the firmware
of the DMC-1, visit the Emotiva website at www.emotivaaudio.com.
“Hum” Noises
This problem is more than likely caused by a “ground loop” in your system, rather than a fault
in the DMC-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 DMC-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 DMC-1 or the TV, or any other component. If the hum is
caused by the cable TV line, then 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 (unless purchased through AV123) for assistance.
Disconnect all connections from the DMC-1 to your TV.
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
DMC-1, until you identify the problem. (Ground loop isolators are available for audio lines and
video. Ask your Emotiva Dealer 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 dealers and technical support staff
will assist you.
