SHOUTcast v2 Servers with sc_trans (legacy) AutoDj require an MP3 license key to unlock broadcasting using an MP3 codec. Your Centova Cast Control panel will notify if the key is required. The new Liquidsoap AutoDj does not require the key.
1 Buy your AutoDJ MP3 Unlock Key [also called: Shoutcast mp3 license key/code or sc_trans unlock key/code].
2. Your Shoutcast sc_trans MP3 Key and unlock code will be generated automatically and sent to your email.
3. Login into your Centova account.
4. Click Settings and enter the AutoDJ tab.
5. You should see the following fields: MP3 unlock key name and MP3 unlock code.
