Surround Mode - Emotiva XMC-1 User Manual

XMC-1: User Manual
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 automated 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 correction
presets that you have configured in the Setup Menu; listed by the names you have configured.
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. If you have already chosen a default Surround Mode,
selecting Auto on this menu will set it to Automatic.
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. Depending on configuration settings in the setup Menu, the XMC-1 will default to the
best choice for a given type of input signal, or to the specific mode you have configured for that
signal type, or to the same surround mode that you manually selected the last time a similar
type of input signal was detected.
