### Program Output

The main output is called **PROGRAM (PGM)**. It is typically the signal that is sent on-air and is available in several formats:

* **RJ45**: delivers **balanced PGM** signal.\
  Always use this connector to route analog signal to the audio processor or link.

  </Tip>
  <Info>
    Solidyne **362HD** and **542APC** processors include analog inputs with RJ45 connectors. The connection is made using a **shielded STP RJ45-RJ45** Ethernet cable.
  </Info>
* **Female TRS**: delivers unbalanced stereo PGM signal.
* **USB (USB-1 Channel)**: the PGM signal is sent to the connected computer, commonly used for Internet streaming.
* **AoIP (optional)**: in consoles with the /AoIP module, PGM is available in multiple formats (PCM, MP3) over Ethernet connection.

### REC Output (Auxiliary)

The **recording (REC)** output is also available in several formats:

* Balanced on **RJ45** connector.
* Unbalanced stereo on **TRS**.
* Digital USB via the **USB-2 Channel**.
* Streaming over **Ethernet** on models with dual /AoIP module.

The nominal output level of the console is **+4 dBu @ 0VU**.\
When using balanced outputs in unbalanced mode, the level drops by 6 dB, therefore **0VU = –2 dBu**.

<Danger>
  **Do not use mono plugs (TS)** to connect the stereo TRS outputs.
</Danger>

<Note>
  If you connect equipment with an **–10 dBV** input level to the console's output, the level may be excessive and cause clipping. In such cases, a **fixed attenuator (resistive divider)** should be used to reduce the level.
</Note>

### Decoded Streaming Audio

The **Audio Out to Bal Line 1** output is only available on consoles with the **/AoIP** option.\
It provides a balanced analog signal containing the **decoded audio from the incoming stream**, typically used to feed the decoded audio back into an analog line input.
