​
Microphone Inputs

The MX2100 has 3 microphone inputs (MIC-1, MIC-2, and MIC-3) with 1/4” (6.25 mm) TRS connectors. The preamplifiers use the local feedback technique, which prevents saturation in the presence of high sound pressure levels (for example, a commentator shouting a goal).

​
Built-in Microphone

  • Electret microphone built into the front of the unit (MIC-4).
  • Allows going on-air even without external microphones.
  • Shares the level control with the line input and Bluetooth return.
MIC-4 is disabled if the USB connection (to a computer or charger) is used or if the line input is connected.
The MIC-4/LIN/Bluetooth control presents different signals depending on the operating scenario (see Console Operation).

​
Line Input

  • LIN-4: mono line input.
  • Accepts direct connection from headphone outputs of portable recorders, mobile phones, notebooks, tablets, etc.
  • A 1/8” stereo miniplug cable can be used, although in the console the ring (right channel) remains unconnected.
  • Shares level control with the built-in microphone (MIC-4) and the Bluetooth return.
If stereo equipment is connected, the input will use only one channel. The plug’s ring (right channel) remains unconnected in the console.

​
Program Output (Bal Out)

  • Balanced, mono output with TRS 1/8” connector.
  • Mix of signals: MIC-1, MIC-2, MIC-3/USB and MIC-4/LINE/Bluetooth.

​
Dynamic Processing

The PGM signal passes through a dynamic range compressor designed for human voice:
  • Controls peaks and prevents level differences.
  • Distortion‑free with no increase in background noise.
  • Compression indicated by two front‑panel LEDs.
This system allows interviews to be conducted with consistent levels, without requiring an audio operator. The PGM output can be used to:
  • Connect to portable digital recorders and obtain high‑quality recordings.
  • Send signal to studios via VHF/UHF radio link in high quality (30–15,000 Hz).

​
Headphone Outputs

  • Internal headphone signal distribution.
  • 3 outputs with 3.5 mm minijack connectors.
  • The mix sent to the headphones depends on the connection mode and work scenario (see Console Operation).

​
Audio USB

The MX2100 console was designed to simplify connection with laptops, enabling Internet streaming transmissions.
  • The USB connection handles both sends and returns of the signal with Studios.
  • A standard mini-USB to USB-A male cable is used.

​
Automatic Operating System Detection

When connecting the MX2100 to a computer running Windows 7/8/10, Linux, or OS-X:
  • The operating system detects the console and automatically installs the necessary drivers.
  • No additional drivers are required.
On Windows, the USB device is automatically configured as the default device.

​
Detected Devices

The console is identified as:
  • USB playback device (stereo out): the computer sends audio to the MX2100.
  • USB recording device (stereo in): the computer receives audio from the MX2100.

​
USB Power Supply

  • Internal rechargeable Ni-Cd battery.
  • Battery life: 16 hours of continuous use thanks to CMOS technology.
  • Automatic multi-voltage external USB charger (100–240 VAC) included.
  • Connection via USB-A to mini-USB cable.

​
Charging Time and Method

  • Time for full charge: ~12 hours.
  • Above that value, the charging current decreases and it can be left connected without risk.
  • Red LED (CHG) indicates charging in progress.
  • The LED remains lit while the unit is connected to the charger, even when powered off.
  • It can also be recharged by connecting it via USB to a computer.
