Radio stations in search of a professional-grade digital broadcast mixer will be impressed with the Axel Technology Oxygen 2000 , a fully digital broadcast console that's designed for on-air and production work. The mixer features 12 compact faders, five microphone inputs with automix, and a powerful internal audio routing with a wide range of controls and I/O in a rugged and classy steel chassis.
The integrated digital signal processing delivers high-end quality with the latest features and flexibility. The console is as reliable and easy-to-use as an analog mixing console. The Oxygen 2000 features low latency, users preset, smart keys, EQ, compressors, telephone hybrid, HDMI output, analog and digital I/O, and USB. Oxygen 2000 can be remotely controlled through a dedicated application.

Automix
Automix feature simplifies mixing activities in the presence of many guests in the studio
The function adds, to the existing sources, a new source called Automix, which is the sum of all enabled microphones
The Automix source has all the features of a microphone source such as:
- Studio/control room loudspeakers control
- Studio/control room light control
- Can be used as audio in private mode for phone calls
Using this new source, the user can manage in a very simple manner all the microphones of the studio with a series of benefits:
- Just 1 fader for the management of studio microphones
- A dedicated AGC section for each microphone input automatically adjusts the correct level
- Automatic management of attenuation on microphones not in use, simulating a slight closure of the fader
- Final compressor that allows an automatic leveling of the Automix source
- Possibility to use the microphones individually
This feature further simplifies the work of the mixer engineer, even in the case he/she is also the host of the show
Available settings in the Automix menu:
- MIC-1 ON/OFF
- MIC-2 ON/OFF
- MIC-3 ON/OFF
- MIC-4 ON/OFF (only for consoles with 5 Mic)
- MIC-5 ON/OFF (only for consoles with 5 Mic)

USB Audio I/O
- 2 built-in stereo USB (Type-B) I/O audio interfaces allow to directly connect the PC to the Oxygen 2000 console, with no need for audio cards
- In fact, the PC detects each of the console USB as a digital audio card with 1 stereo inputs and 1 stereo outputs for simultaneous playout and recording
