MX700 Dual Screen One-side Speaker working

We have an MX700 Dual Screen running latest CE Software.

 

The layout has been configured as below when in a P-2-P call.

 

SP1 SP2 SP3 SP4 SP5 SP6 SP7 SP8 SP9 SP10
Screen-1(Remote Party Video) Screen-2(Self-view Video)

SP=Speaker

The issue is that remote party audio is only being played through SP1 to SP5 and the remaining SP6 to SP10 is not being used.

 

Is there a setting where it will use all Speakers.

 

The documenation regarding speaker for MX Series is slim.

 

Thanks.

Re: MX700 Dual Screen One-side Speaker working

Once the cables are verified, execute this command in order to test that the speakers function for TC Version 7.3 and later:
xcommand experimental audio speakercheck
After you execute the command from the CLI, you hear a sound from each speaker one-by-one (for a couple of seconds from each speaker in order to confirm the speaker?s connection/functionality) and you receive this output:
OK
*r AudioSpeakerarrayResult Speaker 1 Detected: "No"
*r AudioSpeakerarrayResult Speaker 2 Detected: "Yes"
*r AudioSpeakerarrayResult Speaker 3 Detected: "No"
*r AudioSpeakerarrayResult Speaker 4 Detected: "Yes"
*r AudioSpeakerarrayResult Speaker 5 Detected: "No"
*r AudioSpeakerarrayResult Speaker 6 Detected: "No"
*r AudioSpeakerarrayResult Speaker 7 Detected: "No"
*r AudioSpeakerarrayResult Speaker 8 Detected: "No"
*r AudioSpeakerarrayResult Speaker 9 Detected: "No"
*r AudioSpeakerarrayResult Speaker 10 Detected: "No"
** end
The default measurement length is one second per loudspeaker. Ideally the output from the command should be "Yes" for all speakers, but false negatives might happen. If you increase the measurement length with the optional parameter Measurement Length, you can improve the robustness of the test.

Re: MX700 Dual Screen One-side Speaker working

MX700 Speaker Functionality
If people speak from a remote site, their voices are heard predominantly on the center speaker for both sides (the third speaker for the right and the left monitor).
With the current TelePresence Codec (TC) software (as of TC Version 7.3), the codecs in the MX700/800 systems use custom loudspeaker array processing in order to synthesize two logical (Left / Right) loudspeakers.
All loudspeakers are in use at lower frequencies, while at high frequencies, only one speaker is used per channel. For lower mid-range frequencies, the sound is distributed among a subset of the available loudspeakers. This behavior is completely defined by the codec software, so later upgrades to the behavior benefit all systems in the field.
Hence, the audio is not played through all of the speakers. Only a certain level of frequency is audible from different speakers. For example, if you play song from your PC connected to the codec, only the center speaker plays the song predominantly, whereas the others only play bass/music/low-frequency.
• The lower-frequency content is always played back on the bass drivers.
• Lower mid-range frequencies are distributed among multiple loudspeakers above the screens.

Re: MX700 Dual Screen One-side Speaker working

Hi Justin,

 

Thanks for your input.

 

The software is Collobartion Endpoint software and the command doesnt work:

"xcommand experimental audio speakercheck"

 

I'm not finding any information regarding speaker setup for the CE software.

1.)

The command to test speakers for MX Series EP running CE is:

 

xcommand Audio speakercheck MeasurementLength: 5

 

2.)

Question:-  Is it still possible to enable all the speakers of MX700 / MX800 unit by any configurations or root changes.

BU Reply:- Not with the current software versions available.

 

Thanks for the assist Justin.
