Zone 2 does not play digital inputs
Zone 2 can play analog sources independent of what is playing in the Main Zone. It cannot play from
a digital-only source unless that input is selected and playing in the Main Zone. To play a source
such as a DVD player in Zone 2 independent of the Main Zone, make sure you connect the player’s
L/R analog audio output to the DMC-1 too.
External Amplifier(s) Shut Down (Often or Prematurely)
Check the following:
Make sure each speaker’s average impedance is not less than your amplifiers can safely handle.
The amplifier(s) have good ventilation, no vents are covered.
Try setting all the speakers to Small, and let your subwoofers handle the heavy bass.
Check that the amplifier(s) power output is a good match for your speakers. If your speakers are inefficient,
consider using larger power amplifiers.
Make sure all wiring is correct and there are no shorts.
DMC-1 “Locks Up” (No Response)
Unplug AC power momentarily, and press Power to turn back on
If this does not work, try the reset procedure.
Reset Procedure
The DMC-1 is a microprocessor controlled device of great complexity. Occasional power fluctuations
and spikes may cause the DMC-1 to “lock up” or act strangely. The DMC-1 can be reset as follows.
On pages 90-92, write down your calibration settings, input settings, Tuner presets, and any other settings
you have made.
Press the power button to turn the unit off, or turn it off from the wall for a moment.
Press and continue to hold down the front panel Power button and the Tone DOWN button at 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.
