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.
It is recommended that microphones on twin inputs be of the same brand and model to maintain signal uniformity.
  • 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.
Dynamic microphones are designed to handle 48V phantom, so they can be mixed with condenser microphones without risk.

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.
