DB9009-TX How to: How can I lock the front panel keyboard?
To prevent unauthorized local access, the unit offers password protected keyboard locking. By default the keyboard is unprotected. To enable this function, using the front panel navigational menu, go to Settings > Security > Front Panel, then press OK and ENABLE the Access Control function. Set the preferred 4 digit password and access timeout.
Once the keyboard lock function is enabled, every attempt to use it will require a password: ENTER PASSWORD:0***. Access will be denied upon false entry.
DB9009-TX How to: How to unlock the front panel keyboard? I have forgotten the password / I have enabled the function unintentionally.
If the “Keyboard unlock” function has been activated by mistake, try to unlock it using the default password 01234. In order to deactivate the code protection, once the front panel menu is unlocked follow the menu path Menu > Settings > Security > Front Panel > Access control and then select Disable.
If you do not manage to unlock the front panel with the default password, nevertheless whether it has been changed intentionally or not, the unit should be returned to its factory defaults in order for the password security to be disabled.
DB9009-TX How to: I have forgotten my password for the WEB Interface. What should I do?
The WEB Interface password could be viewed/changed via the front panel navigational menu. The menu path is Menu > Settings > Security > Remote Access.
DB9009-TX How to: Can the DB9009-TX be used as a multicast sender?
The DB9009-TX IP Audio Encoder can send audio to a number of clients simultaneously, provided that a multicast address is being entered as a client address. The IP Multicast Group address should be specified in the RTP senders' settings.
DB9009-TX How to: How can the encoder be set to act as a Streaming Audio Server?
Prior to implementing the below written adjustments, the following requirements should be fulfilled:
DB9000-TX/DB90-TX/DB9009-TX/DB91-TX must have a static IP address;
If the device is placed behind a router, you will have to make sure that the Port and Stream Server are properly NAT forwarded;
DB9000-RX/DB90-RX/DB9009-RX/DB91-RX may have a dynamic IP address;
DB9000-RX/DB90-RX/DB9009-RX/DB91-RX should have access to DB9000-TX/DB90-TX/DB9009-TX/DB91-TXover the network (Internet or LAN).
In order for the DB9000-TX/DB90-TX/DB9009-TX/DB91-TX to be used as a Streaming Audio Server the following settings should be applied, via the WEB Interface:
Go to Configuration > IP Audio;
Audio Settings section - Choose the preferred audio signal input. Assign Encoder +Sample rate and the desired signal quality. The combination of these parameters will define the required minimum bandwidth of your network connection;
Stream Settings section - Specify the Port to be used and the maximum supported connections. Preferably change the name of the stream to identify you server easily
DB9009-TX How to: DB9000-TX/DB90-TX cannot be assigned with static IP. How can I configure it?
For further information on the variants of usage when DB9000-TX/DB90-TX cannot be set with static IP, refer to question:
"How DB9000-TX/DB90-TX can be used as an Icecast Source Client, feeding with audio DB9000-RX/DB90-RX, working as an Icecast Source Server, or an Icecast Distribution Server?"
"How DB9000-TX/DB90-TX can be used as an RTP Sender, feeding with audio DB9000-RX/DB90-RX, working as an RTP receiver?"
DB9009-TX How to: Can the DB90-TX/DB9000-TX be used as an audio source for Shoutcast system?
The DB90-TX/DB9000-TX can be used as an Icecast Source client, but not as Shoutcast Source. Shoutctast/Icecast in the product specifications refers to the built-in Icecast/Shoutcast compatible stream server, i.e. clients as Winamp, for example, can connect to DB90-TX/DB9000-TX and play the audio.
DB9009-TX How to: What should be the buffer level? How can I apply the needed settings?
The Buffer is used to supply an audio at the output when disconnection or a problem with the connection is present. The higher the buffer level is the longer the protection time will be. Though, the audio delay will be increased. The level at which the buffer will be set depends on your preferences and expected results as it comes to the quality of the connection. If a connection loss is not expected, the buffer level could be decreased. If the connection is unstable (such as 3G Network), we recommend a higher buffer level to be set.
The buffer level is set in bytes, thus, the audio delay depends on the bit-rate of the audio stream. For example - audio with higher bit-rate will have a lower delay compared to audio with the lowest bit-rate at the same level of the buffer.
The buffer level is the received amount of audio data at which the RX will start playing the audio. In the DB90/9000-TX settings should be set the pre-buffering level, which is the initial amount of data that is sent to the RX in order for the buffer to be filled rapidly i.e. the connection to be built quickly. We recommend the same values to both units to be set.
All needed settings are applied via the WEB Interface.
- For DB90/9000-RX go to Configuration > IP Audio > IP Audio Client subsection and set the pre-buffer level;
- For DB90/9000-TX go to Configuration > IP Audio > Stream Settings subsection and select the pre-buffer level from the drop-down menu.
