Axel Technology Oxygen 3000 Plus Digital Broadcast Console (12-Fader)

Designed for professional radio on-air and production applications, the Axel Technology Oxygen 3000 Plus is a digital broadcast mixer with 12 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).

Digital Input Line

• 1 AES/EBU Input on XLR with sample rate Converter (32 to 192 kHz), on each audio I/O board

Digital Output

• 1 AES/EBU output (32 to 192 kHz) on XLR on each audio I/O board

USB Audio I/O

• Two built-in stereo USB-B (2 stereo inputs, 1 stereo output) audio interfaces on each audio I/O board, allow to directly connect the PC to the Oxygen 3000 Plus console, with no need for extra audio cards (the PC detects the console as a digital audio card with two stereo inputs and one stereo output, for simultaneous playout and recording)

• For each audio I/O board, one unbalanced output line on 1/4" for control room and studio headphones
• Adjustable maximum control room and studio speakers volume
• Adjustable maximum control room and studio headphones volume
• Adjustable cut or attenuation mode (-40, -30, -20, -10 dB) on control room and studio speakers
• Independent source selection (PGM, Sub, Aux1, Aux2, Ext1, Ext2) for control room and studio speakers, control room and studio headphones with or without PFL
• Independent talkback management on control room and studio speakers
• Independent talkback management on control room, studio and guest headphones
• Selectable source for guest headphones (PGM, Sub, Aux1, Aux2, Ext1, Ext2)
• Same source selection for control room and studio headphones, with independent level

• Telephone Hybrid: One POTS/PSTN telephone line with line in and Tel Set connection on each audio I/O board
• Telco: 1 in/out N-1 to connect external telephone hybrid with control via TLC/GPIO, on each audio I/O board
• Up to 6 Telco using other input sources, on each audio I/O board
• GPI and GPO management on max 5 Telco I/O, on each audio I/O board
• Ring and hook on F keys for each TELCO I/O
• N-1 on Telco outputs for all Bus (PGM, Sub, Aux 1, and Aux 2)

• GPI: 9 on each audio I/O board, for talkback, telephone, hybrid, or other features
• GPO: 9 on each audio I/O board, to control on-air lights or provide hook and ring commands for external telephone hybrid
• User custom GPIs (e.g. ring, talkback, channel on/off, etc.)
• User custom GPOs (e.g. hook / on-air, studio light, control room light)

• 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

• Direct Firmware update via Internet
• WEB UI for Console configuration and service features (save, restore, update, logs, etc.)
• Conditional Access (4-digit PIN) to limit console configurations to authorized users
• 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 control panel configuration with 10 snapshots
• 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

• 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.

• 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.

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
• Audio output level (loudspeaker
