Emotiva XMC-1 User Manual page 98

Problem: It seems like I have to set the Volume on my XMC-1 to a much higher/lower
number than I did yesterday to get the same output volume.
Reason: The audio processors in the XMC-1 have a feature called normalization; if you adjust the
Tone Trims or Level Trims in such a way that the result is to raise the overall gain, the XMC-1 will use
its internal master gain control to ensure that digital audio signals aren't clipped. Because this only
happens while you're changing the settings, it doesn't affect the dynamics of the music in any way, but
it may alter the Volume setting required to produce a specific output level.
• This is normal.
Note: Normalization is a static setting that affects only the overall gain of the XMC-1 (similar
to the Master Gain setting on an equalizer), and is necessary to ensure that excessive boost
applied by user configuration settings won't cause the XMC-1 to clip loud passages in the music.
Normalization is applied at the time you make each user level or trim setting. It does NoT affect
the dynamics or dynamic range of the music.
Problem: My XMC-1 seems to be acting oddly; sometimes the Volume control doesn't
work, or the XMC-1 turns itself On of Off when I switch the TV or my Blu-Ray player
On.
Reason: CEC is a remote control protocol supported to varying degrees by many TVs and Blu-Ray
players. CEC is intended to provide a convenient way for some devices to control others; for example,
to allow your Blu-Ray player to tell the XMC-1 to switch On when you insert a disc and press Play.
Different vendors may refer to CEC by different names and, unfortunately, implementations vary and
not everyone follows the same standard. Your XMC-1 ships with its CEC options disabled by default, but
it may still accept and act upon certain CEC commands it receives from other devices.
• Disable CEC in your other devices. (Most TVs and many Blu-Ray players have some CEC
features). You may have to look online, or consult the manufacturers of your other devices, to
determine what they call CEC on their devices. Alternately, you can simply disable any "remote
control" features on other equipment that you don't use.
• (We are specifically aware of CEC issues when using the XMC-1 with Oppo model BDP-103
and BDP-105 Blu-Ray players, and we strongly suggest disabling CEC support on them.)
