Play a source through Analog In¶
The Analog In jack on your CAST PRO-1 turns any line-level source into something Music Assistant can play. Plug in a turntable, TV, or CD player, and it shows up in Music Assistant as a Sendspin Source. Play it on the speakers connected to your CAST PRO-1, or on any other Music Assistant player in your home.
Before you start
Finish the Getting Started guide first, so your CAST PRO-1 is in Home Assistant and Music Assistant is running.
What you'll need¶
- A line-level source. Most TVs, CD players, and streamers output line level. A turntable needs a phono preamp between it and the CAST PRO-1, unless the turntable has one built in. If the turntable has a PHONO / LINE switch on the back, set it to LINE.
- A cable with a 3.5mm plug for the CAST PRO-1 end. For a source with RCA outputs, use an RCA-to-3.5mm cable.
Connect your source¶
1. Plug the source into the Analog In jack, the left of the two 3.5mm jacks. The Analog/Optical Out jack is output only, so a source plugged in there won't play.
Play it in Music Assistant¶
1. Open Music Assistant from the Home Assistant sidebar and select Browse.
2. Select Sendspin Source (Apollo CAST_PRO-1 xxxxxx), where xxxxxx matches the end of your device's name. (1)
- Your device's name is at the top of its device page in Home Assistant, for example Apollo CAST_PRO-1 04c6d0.
3. Pick the player to hear it on. Choose your CAST PRO-1 to play the source through its own speakers, or any other player to hear it in another room.
Choose the streaming quality¶
The Line In Streaming setting on your CAST PRO-1's device page sets how it sends your source over the network:
| Option | When to use it |
|---|---|
| Compressed | The default. Best for a weaker Wi-Fi connection, since it uses less bandwidth. |
| Lossless | Full quality. Pick it when your CAST PRO-1 is on Ethernet or a strong Wi-Fi signal. |
