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
UMC-1 too.

EXTERNAL AMPLIFIER(S) SHUT DOWN (Often or Prematurely)

Check the following:
Make sure triggers are correctly assigned!

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.

UMC-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.

PROBLEMS UPDATING UMC-1 FIRMWARE

Check that the serial cable is connected correctly between the UMC-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.

"HUM" NOISES

•
This problem is more than likely caused by a "ground loop" in your system, rather than a fault in the UMC-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 UMC-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 UMC-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 UMC-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 UMC-1, until you

identify the problem. (Ground loop isolators are available for audio lines and video. Ask your Emotiva Dealer or
a professional home entertainment integrator 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.
