Automix

The Automix feature simplifies mixing activities if many guests are in the studio.

The Automix adds a new source to the existing ones (called “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 loudspeakers 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.

This feature simplifies the work of the mixer engineer, especially if he/she is also hosting the show.

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 set up and information, fader and buttons control and 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.

Displays

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 & 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 & studio)
• Large Clock
• Audio output level (Loudspeakers & Headphones)
• On-Air microphone
• Telephone active
• 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 can be equipped with a Bluetooth 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 Bluetooth connection modes: bidirectional to support phone calls; monodirectional to put on air high quality stereo audio (A2DP) streamed by Bluetooth sources.

With Bluetooth 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).

Redundant Power Supply

Oxygen 3000 Plus is equipped with an external Universal Switching Power Supply 12V (with 4 poles XLR connections) able to operate with a voltage between 90Vac and 264Vac and a frequency between 50 and 60Hz. This PSU can adapt itself to the operating voltage of any country in the world. Optionally the console can be equipped with a redundant power supply: in this configuration the fault of one of the PSU is promptly noticed on the 7” display.

Talk Box

Talk Box is very simple to connect to the On Air Console: it takes 2 RJ45 cables of the length that is needed to connect it to the mixer. It is possible to connect up to 4 Talk Boxes on each Audio I/O Board. The Talk Box manages a direct connection of the microphone and its own On-Air light. It is also possible to connect it to the studio’s On-Air Light. The Talk Box has a headphone amplifier with two 6.3mm outputs. Through the two backlit buttons it is possible to activate and deactivate your own microphone (On/Off/Cough) or enable Talk back to the console.

Dante™ AoIP Interface

Oxygen 3000 Plus can be equipped with a Dante™ interface (also supporting AES67 and SMPTE ST 2110-30 transport protocols) which provides 16 Inputs and 16 Outputs or 32 Inputs and 32 Outputs on dedicated Ethernet port, with independent Level Control and Sample Rate Conversion.

Dante™ AoIP interface is installed at the factory and has to be requested at the order.
