+The **Off Air Metadata** field configures the text that will be sent to any configured streaming servers, and from there on to media players, when Airtime isn't streaming any output.
 
 Below this is the **Enable Replay Gain** checkbox which, if checked, automatically adjusts Airtime's output level to an average of -14dBFS, based on prior analysis of the level of individual files in the **Library**. This feature helps guard against unwanted changes in Airtime's output level caused by the typical variation in average level of recordings made in different studios at different times. The correction value for each file can be viewed by enabling the ReplayGain column in the **Library**.
 
 If Replay Gain is enabled, output level can be adjusted up to 10dB louder or quieter from the reference level of -14dBFS by clicking and dragging the **Replay Gain Modifier** control. Increasing level too far is likely to result in clipping (distortion) since the output level is adjusted to be greater than that of the original files. This scenario is indicated by amplitude correction factors greater than 1.0 in the Liquidsoap log file.

 Input streams must have a **Port** for the remote broadcaster to connect to, which should be a number in the range from 1024 to 49151. If you have the Icecast or SHOUTcast streaming server running on the same machine as Airtime, you should avoid using port 8000 or 8001 for either type of Airtime input stream. This is because both Icecast and SHOUTcast use port 8000, and SHOUTcast also uses port 8001. If the usernames and passwords were similar, remote broadcasters might accidentally connect to the streaming server directly, bypassing Airtime.
 
-To avoid further confusion, it is also recommended that you set a different **Mount Point** (the specific filename for broadcasters and listeners to connect to) from that used on your public Icecast or SHOUTcast server.

 If your Airtime server is behind a firewall, and you wish remote broadcasters to connect input streams to it across the public Internet, you may need to click the **Override** link to set a **Connection URL** which is available from outside your local area network. This URL might be based on the domain name assigned to the router which forwards the appropriate port to your Airtime server. Then click **OK** to save the new connection URL.

For example, if you enter the wrong password, you will see an _Authentication Required_ error message. To fix this, enter the correct password in the **Additional Options** box, and click the **Save** button. If the streaming server is down for any reason, or you have entered an incorrect **Server** name or **Port** number, you will see the message _Can not connect to the streaming server_.
