# Monitoring

> Speaker and Headphone Connections in Studio and Control Room

## Control Room Monitoring

The **CONTROL** outputs feature **1/8" female TRS (mini-jack)** connectors for speakers and headphones. The speaker output operates at a nominal level of **0 dBu**, designed for connection to active monitors.\
In the console's MONITOR section, you'll find the controls for signal routing and level adjustment for both speakers and headphones.

<Note>
  The **Control Speaker** output is automatically muted when **Talk-back** is engaged, preventing feedback with the announcer microphone.
</Note>

***

## Studio Monitoring

The console delivers monitoring signals to the Studio via **STUDIO MONITOR OUT**, with an RJ45 connector. The connection is made using **straight-through STP RJ45-RJ45 cable** to the optional **Solidyne Studiobox HD3/HD5** monitor units.

<Danger>
  This output **must not be connected** using standard audio output RJ45 cables.\
  It is **not compatible** with the **StudioHub** standard.
</Danger>

Features:

* Studio speakers **automatically mute** when microphones are opened.
* The headphone signal **is never muted**. It always receives the console-assigned signal and the talkback microphone audio.

For details, see the **Studiobox HD3 / HD5 Monitoring Modules** section.

## Single-Booth Monitoring

When the console is used in an integrated or single-booth studio, it is advisable to connect the speakers to the **STUDIO MONITOR** output.

<Warning>
  The CONTROL speaker output **is not muted when microphones are activated**, creating a risk of feedback if microphones and speakers are in the same room.
</Warning>

## Optional Studiobox Connection

The console includes a **Y-cable adapter** (RJ45 to dual TRS jack) for connecting generic headphone distribution amplifiers and powered monitors.

* The **STUDIO MONITOR** output delivers fixed-level signals
* When not using Studiobox, speaker level is adjusted from the monitors' own controls
* A dual-input headphone distribution amplifier may be used to control monitor volume from the console
  * Input A → headphone signal
  * Input B → speaker signal
