## STUDIO MONITOR Output Connector

The **STUDIO MONITOR** output connector carries the monitoring signals to the main studio (Studio A).

**Solidyne StudioBox HD3 and HD5** monitoring bays connect directly to this output using an **RJ45–RJ45 STP** cable with **pin-to-pin** connection.

When not using a StudioBox, the console includes an **RJ45 to audio connectors** adapter cable, allowing direct connection of active speakers and headphone distributors in the studio.

<Warning>
  The **STUDIO MONITOR** output must not be connected using cables other than the original or through generic RJ45 adapter sections. This can cause failures or damage to the Studio Monitor output.
</Warning>

The signals present in the **STUDIO MONITOR** connector are:

| **PIN** | **SIGNAL**               |
| :-----: | ------------------------ |
|    1    | Headphones Left (+4 dBu) |
|    2    | Headphones Right         |
|    3    | GND                      |
|    4    | ON-AIR (+14 V)           |
|    5    | Talkback to Control Room |
|    6    | VCC +14 V                |
|    7    | Speakers Left (+4 dBu)   |
|    8    | Speakers Right           |
