Designed for professional radio on-air and production applications, the Axel Technology Oxygen 3000 Plus is a digital broadcast mixer with 8 faders and a single audio I/O board with five microphone inputs, two stereo analog inputs, Bluetooth, USB, and digital (AES/EBU) I/O. Additional inputs include telephone hybrid or Telco with GPIO and streaming I/O.
Notable features include 7" display, HDMI output, low latency operation, users presets, smart keys, EQ, and compressors. An optional presenter Talkbox manages a direct connection of the microphone, an integrated headphone amplifier (2 x 1/4"), an on-air light and two backlit buttons (On/Off Console Talk Back).

- User custom GPIs (e.g. ring, talkback, channel on/off, etc.)
- User custom GPOs (e.g. hook / on-air, studio light, control room light)
Automix
- The automix feature simplifies mixing activities if many guests are in the studio
- The automix adds a new source to the existing ones (automix), and it will be the sum of all the enabled microphones
- The automix source has all the features of a normal microphone source such as:
- Studio/control room loudspeaker control
- Studio/control room light control
- Can be used as audio in private mode for phone calls
- Using the Automix source, the user can manage in a very simple way all the microphones of the studio with many benefits:
- Managing all the studio’s microphones with one fader only
- 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 with automatic leveling of the Automix source
- Possibility to use the microphones individually

- Save and recall EQ presets (up to 10)
- New real-time EQ algorithm with graphic
- Fast and accurate Meters on 2.2” TFT IPS displays

- Save and recall total console configuration. The configuration can be saved to internal memory (microSD), USB, and PC (via WEB interface)
- Gain adjustment knobs with adaptive speed
- Dimmable buttons light
- Adjustable fader on/off threshold (from -50 dB to 0 dB)
- Count-up / timer on studio and control room microphones on the built-in 7″ display
Software Remote Control
- Oxygen Remoter is a software tool available for free with any Oxygen console. It offers advanced remote control features such as accessing to any setup information, fader or buttons control, or any other operation available on the physical consoles. It is very useful especially for compact consoles and in any environment that has limited space.
- The Virtual Fader technology enables users to assign each input to a virtual fader/channel on the remote surface, this is of course very useful when controlling channels remotely. Additionally, transforming the A/B pair into two virtual faders is a smart solution that maximizes the management of the available sources.
- Oxygen Remoter can remotely control multiple consoles and create an ecosystem, this can be very helpful for remote productions where, for instance, a portion of the channels may need to be controlled from a studio while the others are still managed from the physical surface in the control room.
- Oxygen Remoter is a powerful tool that provides extra flexibility and control’s tools to all the Oxygen consoles.
- Oxygen Remoter is downloadable from the Oxygen console’s administration web page.
Display
- On the OXYGEN 3000 Plus, AxelTech reinvented the experience between the studio engineer and the console.
- The 7″ TFT IPS graphic display shows all the airing parameters and with the 4 rotary knobs allows the fast and intuitive programming of all the mixer’s parameters.
- Selectable home page layouts are available with many theme icons. Default page shows the levels and the A and B source names for any fader.
- Four 2.2 ”TFT IPS displays have been implemented for an immediate and complete monitoring of the outputs.
- The 2.2 ”TFT IPS displays on top of each fader show the channel status, levels, sources and main settings.
HDMI Output
The HDMI output connects the console to a HD display monitor and it can monitor all the following information:
- Audio input source levels
- 4+1 BUS output levels
- A/B source names assigned of 10 channels
- Display on-air sources
- Microphone On timer (control room and studio)
- Large clock

- HDMI output combined with 4 rotary knobs allow the fast and intuitive programming of all the mixer parameters.
- The programming GUI has been designed in order to be very easy and intuitive.
- Selectable home page layouts are available, with many theme icons.
HDMI output can be customized with the user’s logo. Selectable display layouts are available.
Bluetooth
- Oxygen 3000 Plus has a BT module on each audio I/O board. This allows airing the calls made via GSM, Skype, Viber and WhatsApp with a smartphone, a tablet, or a PC. Oxygen 3000 Plus has two BT connection modes: Bidirectional, to support phone calls, and Monodirectional, to put on-air high-quality stereo audio (A2DP) streamed by BT sources.
- With BT calls, PFL enables private conversation mode.
Built-In Decoder and Streamer
Oxygen 3000 Plus, in addition to analog/digital/AoIP inputs and outputs, are open to integration with the IP world, thanks to the ability to decode an audio streams (stereo or mono) as input and generate an output audio stream (stereo or mono).
