# Operation of the DX Series

> Operation of the DX816 Consoles

## Introduction

The console consists of several main sections:

* Input channels.
* Telecommunications channel.
* Monitor and studio command routing.
* Pre-fade listen (**CUE**).
* Level meters.

The various audio sources (microphones, computers, audio interfaces, links, telephone lines, etc.) enter the console through the **input channels**, which amplify them.

The console mixes all signals to generate two main outputs:

* **PGM**: signal sent to the audio processor and then to the transmitter or streaming.
* **REC**: independent or auxiliary recording signal.

The operator controls each signal's level using the **main faders**.\
Via the routing buttons (**PGM / REC**), signals are sent to their corresponding outputs.

The **CUE** buttons allow listening to these signals before sending them on-air.

* Line channels go on-air when opening the fader.
* Microphone channels additionally require pressing the **MASTER MIC** button.
* The **BAL-1** and **BAL-2** line channels feature dual inputs (balanced and unbalanced), selectable from the front panel.

## Microphone Inputs

* **DX816**: features 3 microphone faders, but the MIC-2 and MIC-3 inputs include a second connector that shares a preamplifier. This allows channels 2 and 3 to handle two microphones simultaneously, supporting up to **5 microphones**.
* **DX822**: the same applies to MIC-4 and MIC-5 channels. In total, it supports **10 microphones across 6 faders**.

<Warning>
  It is recommended that microphones on twin inputs be of the **same brand and model** to maintain signal uniformity.
</Warning>

* All microphone inputs support **48V phantom power**, switchable in groups.
* On the DX816, **equalization** is global for all microphones.
* On the DX822, a second equalizer affects MIC-4, MIC-5, and MIC-6 (and their twin inputs).

**Compression** applies only to microphone channels. Its action depends on the program level. The **gain reduction indicator** shows the compressor's work.\
If two microphones share a channel, the compressor balances their levels, smoothing differences due to proximity or voice intensity.

<Note>
  Dynamic microphones are designed to handle **48V phantom**, so they can be mixed with condenser microphones without risk.
</Note>

## Line Inputs and Digital Modules

* **BAL-1 and BAL-2** channels handle balanced and unbalanced auxiliary inputs, selectable from the front panel.
* The **USB** modules manage two stereo signals via USB.
* The USB connection sends **PGM (USB-1)** and **REC (USB-2)** signals to the computer.
* In models with **AoIP** option, up to two Ethernet modules can be installed for streaming transmission/reception.
  * Available signals: PGM and REC.
  * Each AoIP module also receives a streaming signal, which is assigned to a line channel.

## Indicators

The console's meter bridge includes:

* **LED VU meters** for program and record (peak-average level).
* **Microphone compressor indicator**.
