You can select speakers:
• by clicking on the speaker in the 3D view;

• by clicking on one of the lines of the table.
The currently selected speaker is displayed in yellow in the 3D view. The available settings for each speaker are the
following :
• Dolby, Dolby Atmos, Auro3D, DTS and DTS:X channel mapping : see above.
• Amplification: see above.
•
Output Channel : specifies the physical output to be used for the speaker/driver.
• Pink noise : plays a -20dBFS pink noise on the specified output.
6.3.9 _CONFIGURE THE CROSSOVER SETTINGS (OPTIONAL)
If you want to use the active crossovers of the Altitude
16
, you must use the speaker
configuration table to:
Specify the type of amplification: bi-amp, tri-amp or quad-amp;
Specify the crossover frequency.
The parameters related to crossover settings are the following:
• Amplification: sets the number of ways of the speaker in case of multi-amplification;
• Low freq cut-off: sets the crossover frequencies;
• for bi-amp, it is set at 2kHz by default;
• for tri-amp, they are set at 200Hz and 2kHz by default;
• for quad-amp, they are set at 200Hz, 2kHz and 20kHz by default.
NOTES:
• The Altitude
16
handles up to 4-way active crossovers.
• The default crossover filters are Linkwitz Riley 4th order (24dB/Oct).
• Advanced crossover settings are available in the Setup/Active Xovers page of the Advanced Settings user
interface. Further information about the active-crossovers can be found in the Calibrate the Active Crossovers
chapter.
• Please remember that a multi-amplification will consume a number of channels relative to the type of the multi-
amplification.
6.3.10 _MAPPING THE CHANNELS OF DIFFERENT FORMATS
The Immersive Audio Formats (Auro-3D, Dolby Atmos and DTS:X) come with different
channel labels and different speaker placement recommendations. This causes
incompatibility issues that could make it difficult to play the required content correctly.
In the Altitude
16
, each speaker can be assigned to a specific channel for each format in such a way that it will play the
required content regardless of the format being decoded.
In the example below, one speaker was set as the “Top” speaker recommendation of Auro Technologies to reproduce the
content of the Auro 3D Top channel (“voice of god”). This channel also exists in DTS:X as the “Oh” channel but does not
exist in the Dolby Atmos format. Therefore, this speaker will not be used during playback of native Dolby Atmos formats.
