4.3 PARALLEL AUDIO STREAMING AND AUDIO SOURCE PRIORITIES
The scala rider PACKTALK can stream audio from two connected sources simultaneously,
so that you can listen to your music or the radio while holding an intercom conversation.
Parallel Audio Streaming is automatically disabled during mobile phone conversations.
By default, Parallel Audio Streaming is enabled. See section 3 to adjust the settings. If
disabled, the scala rider will automatically determine which audio source to play based
on the priority of the connected devices.
Higher Priority
1. Mobile Phone or GPS instructions
*
2. Intercom (DMC and Bluetooth modes)
3. A2DP (Stereo Bluetooth) audio
4. FM Radio (Built-in)
*GPS instructions from Smartphone GPS Apps are prioritized like A2DP audio

Lower Priority
A2DP audio priority can be congured to be higher than Intercom. See section 3 to adjust settings.
• Incoming mobile phone calls interrupt ongoing intercom calls
• Incoming intercom calls will interrupt FM radio
• Intercom modes all have the same priority - ongoing intercom calls will not be interrupted
by any other intercom call
