## Channels

UNIDEX UX18 has 18 channels:

* **10 channels** with 100 mm faders and **8 "virtual" channels** operated from the touchscreen or via remote web interface.
* 4 channels can work as **groups**, to control **submixes of virtual channels** from mechanical faders.
* Each channel can be assigned to any input.
* Channels are configured in three modes: **MIC**, **LINE**, or **TELCO**, which modifies their behavior and functions.
* They can be assigned to four stereo mix buses: **PGM**, **REC**, **AUX**, and **VBUS**.

## Inputs

UX18 features 5 microphone inputs and 13 line inputs (analog and digital).

* **Microphone: 5 mono balanced**

  With 48V phantom power, 4-band parametric equalizer, dynamic compressor, noise gate, and de-esser.
* **Line: 2 stereo balanced**

  With 3-band parametric equalizer.
* **UNIDEX: 8 mono (4 stereo)**

  Balanced inputs configurable as mono or stereo.

  Allow connecting UDX adapters (microphones, telephone lines, mobile phones via Bluetooth, computers via USB).

  Include 3-band parametric equalizer, dynamic compressor, and noise gates.
* **USB: 4 stereo playback devices**

  Compatible with ASIO 3.0.

  Include 3-band parametric equalizer.
* **AES3: 2 stereo digital inputs**

  With 3-band parametric equalizer.
* **Incoming streaming**

  Not an independent input; when activated, it replaces AES3 input #1.
* **External tuner**

  Stereo input for transmission monitoring. Can also be assigned to channels for use as a conventional input.

## Outputs

There are 9 stereo outputs and monitoring outputs:

* **Program (PGM)**

  Dual balanced analog stereo output.
* **1 REC output** stereo balanced
* **4 unbalanced stereo (assignable)**

  Can be configured as up to 8 mono outputs. Include **mix-minus** option for telephone and VoIP communications.
* **USB: 4 stereo recording devices**
* **AES3: 2 digital outputs**

  Two of them are assignable to any of the buses.
* **Dual streaming PCM/MP3/OPUS**

  Simultaneous transmission via RTP and Icecast/Shoutcast.

## Monitoring and intercom

* Studio monitoring outputs (speakers and headphones).
