Owner's Manual

3D Sound
MRX 1140, by default, is configured for amplification for 7.1.4 main speakers, MRX 740 for 7.1 main speakers, and
MRX 540 for 5.1 main speakers. You can assign height channel information to be sent correctly to the speakers.
Height Speaker Type and Position
Two, four or six speakers may be installed in the ceiling or on the wall near the ceiling and 1 pair of Front Wide. Or,
you may place a type of height speaker referred to as Dolby- enabled on top of existing speakers. A Dolby-enabled
speaker works by bouncing height information off the ceiling. Using the room layout diagrams in this manual as a
guide, select from the following possibilities to match your height speakers:
Front In-Ceiling
Front Dolby-enabled
Front On-Wall
Front Wide
Middle In-Ceiling
Middle Dolby-enabled
Back In-Ceiling

Four Speaker Profiles
The use of one speaker profile is suitable for most systems. However, the MRX/AVM allows up to four unique profiles
with unique speaker selections, bass management, listening position, level calibration, and Anthem Room Correction
(ARC) equalization values. Multiple speaker profiles are useful if your listening room varies according to predictable
sound-altering characteristics such as screen up versus down, a door open versus closed, or stereo listening for music
vs. home theatre.
Speaker profiles can be set up manually using the MRX/AVM’s front display menu or web user interface.
However, it is easier to configure profiles using Anthem’s ARC Genesis software.
