Surround Mode - Emotiva XMC-1 User Manual

The XMC-1 Menu System
Treble Level Tone Trim & Treble Frequency Trim
The Treble Level Tone Trim is used to temporarily alter the relative level of the treble for all
speakers by up to +/- 12 dB in 0.5 dB steps.
The Treble Frequency Trim allows you to configure the turnover frequency for the Treble Level
Tone Trim to any frequency between 500 Hz and 10 kHz.
Lip Synch Delay Trim
The Lip Synch Delay Trim allows you to adjust the lip synch delay from 0 mSec to 200 mSec in
1 mSec steps.
Loudness
The Loudness check box allows you to enable or disable true Fletcher Munson loudness
compensation. Loudness compensation adjusts the audio frequency response to compensate
for the varying frequency response of human hearing at low volume levels. Our hearing is
increasingly less sensitive to very high and very low frequencies as the listening level is reduced,
and the Fletcher Munson loudness curve compensates for this by applying a boost to those
frequencies that increases as the level is reduced.
Input
The Input control is used to select which input on the XMC-1 to listen to or view. Inputs may also
be assigned to individual Input Select buttons in the Setup Menu.
Speaker Presets
The XMC-1 has both Dirac Live automatic room correction, and two full banks of parametric
equalization that can be used for precise, detailed manual correction of room and system
frequency response. The Speaker Preset control allows you to select between the Presets that you
have configured in the Setup Menu; listed by the names you have assigned.
Note: your XMC-1 is configured to use the presets, and Dirac live Automatic Room Correction,
from the setup Menu, under setup speakers. Dirac live is executed and configured from a
separate computer, which must have network access to connect to the XMC-1 and the Internet.

Surround Mode

The Surround Mode control is used to select which surround mode is used by the XMC-1 to
decode incoming audio. This control will present you with a list of available modes and allow you
to override the XMC-1's default selection. Selecting Auto on this menu will instruct the XMC-1 to
automatically choose the best decoding and processing modes based on the incoming audio.
Note: The XMC-1 will automatically detect the surround mode used by incoming audio and
only allow you to choose modes that are appropriate for the type of incoming signal that is
detected. If you set the XMC-1 to Auto, it will automatically select the best choice for a given
type of input signal; if you configure a specific mode, then that mode will be used; if you
configure the XMC-1 to last Used, then it will use the same surround mode that you manually
selected the last time a similar type of input signal was detected.
