Section 6 Configure the settings relating to audio [Audio]
[Microphone sensitivity]
Configure the sensitivity of the microphone according to the installation environment.
•
Available microphone sensitivity: 0 High sensitivity – 5 Low sensitivity
[Internet mode (over HTTP)]
Select “On” when transmitting audio via the Internet.
•
On: Audio will be transmitted using the HTTP port. Refer to
[HTTP port] for further information about the HTTP port number settings.
•
Off: Audio will be transmitted using the UDP port.
Note
•
When “On” is selected, only “Unicast port (AUTO)” will be available for “Transmission type”.
•
When “On” is selected, only IPv4 access is available.
•
When audio cannot be heard even after increasing the volume on the “Live” page, select a higher sensitivity.
•
When the audio heard on the “Live” page is too loud, distorted, or contains noise, select a lower sensitivity.
[Transmission type]
Select the transmission type of audio from the following.
•
Unicast port (AUTO): Up to 3 users can access a single microphone concurrently. “Unicast port” will automatically be selected when transmitting audio from the microphone. When it is unnecessary to fix the port number for audio transmission such as when using in a particular LAN environment, it is recommended to select “Unicast port (AUTO)”.
•
Unicast port (MANUAL): Up to 3 users can access a single microphone concurrently. It is necessary to select “Unicast port” manually to transmit audio from the microphone.
It is possible to fix the port number of the router used for audio transmission via the Internet by setting “Unicast port (MANUAL)” (→
10.1 Configure the network settings [Network]). Refer to the operating instructions of the router in use.
•
Multicast: Unlimited number of users can access a single microphone concurrently. Complete the entry field of “Multicast address”, “Multicast port” and “Multicast TTL/HOPLimit” when transmitting audio with multicast. Refer to
1.1 Display the “Live” page for further information about the maximum concurrent access number.
•
Default: Unicast port (AUTO)
[Unicast port]
Enter the unicast port number (used to transmit audio from the microphone).
•
Available port number: 1024 - 50000 (Only even numbers are available.)
[Multicast address]
Enter the multicast IP address. Audio will be transmitted to the designated IP address.
•
Available IPv4 address: 224.0.0.0 - 239.255.255.255
•
Available IPv6 address: Multicast address starting with “FF”
Note
•
Enter a multicast IP address after checking available multicast addresses.
[Multicast port]
Enter the multicast port number.
•
Available port number: 1024 - 50000 (Only even numbers are available.)
[Multicast TTL/HOPLimit]
Enter a value for “Multicast TTL/HOPLimit”.
IMPORTANT
•
When transmitting audio via a network, the transmitted audio sometimes may not be heard depending on the settings of a proxy server or a firewall. In this case, refer to the network administrator.
•
When two or more network interface cards are installed on the PC in use, the network interface card(s) not used for receiving audio should be invalidated when receiving audio using the multicast port.
