Troubleshooting Guide
The Emotiva DMC-1 is expertly designed and built to provide years of trouble-free perfor-
mance. Most problems that occur can usually be solved by checking your setup or making
sure that the audio and video components connected to the processor are on and fully opera-
tional.
The following information will help you deal with common setup problems you may experi-
ence during normal use of your unit. If problems persist, contact your Emotiva Dealer for help.
No Sound (from one or more full range speakers)
Speaker cables may have come undone. Turn off your system and check the cables, and
tighten the binding posts.
An audio cable may have an internal break.
The volume level is low for the channels concerned. Recheck the calibration procedure (page
59).
The Mute switch is on.
The channel has not been turned on in the Speaker Size Menu (pages 56-57).
The correct surround mode is not selected. (Some DVD discs are stereo only).
Note: In Source Direct mode, only the front left and right speakers are engaged. They must
also be set to Large.
No Subwoofer (or poor output)
The subwoofer’s amplifier is off or its controls are set low.
Are all other speakers set to LARGE in the Speaker Size menus?
SUB is not switched on in the Speaker Size Menu (page 57).
Recheck the calibration procedure (page 59).
Adjust the Crossover and check Bass Management (page 60).
See pages 76-77 to find the best location for your subwoofer.
If the bass is weak during Dolby Digital or DTS playback, check the correct audio output is
selected in your DVD menu, otherwise it may just play stereo into your DMC-1 and you won’t
get the true LFE signal to the subwoofer.
Poor AM Reception
Often one of the main complaints about poor AM reception is that the same AM station can be
heard at different frequencies. Check to see is BOTH wires of the AM loop antenna are con-
nected. A loop antenna is required for AM reception, as it forms part of the front-end tuned
circuit.
