Axel Tech Oxygen 2000 Digital Broadcast Mixer

Oxygen 2000 DSP based audio processing delivers high-end quality and guarantees latest features and flexibility.
Reliable and easy to use as an analogue mixing console Oxygen 2000 offers top class features: Low Latency, Users Preset, Smart Keys, EQ, Compressors, Telephone Hybrid, HDMI Output, Analogue and Digital I/O, USB, Bluetooth, Dante AoIP, Telco, Presenter Talk Box.
Oxygen 2000 can be remotely controlled through a dedicated application.

Bluetooth
Oxygen 2000 is equipped with a Bluetooth module. This makes it possible to send the calls via GSM, Skype, Viber and WhatsApp with a smartphone, a tablet or a PC. Oxygen 2000 has two Bluetooth connection modes: bi-directional to support phone calls; mono-directional to broadcast high-quality stereo sound (A2DP) streamed from Bluetooth sources. With Bluetooth calls, PFL turns on PRIVATE talk mode.

Talk box
It is a device especially for the presenter and guests. Talk Box is very easy to connect to the On Air Console: it requires 2 RJ45 cables of the length needed to connect it to the mixer. It is possible to connect a maximum of 2 Talk Boxes to the Oxygen 2000. The Talk Box offers a direct connection of the microphone and the associated On-Air light, it is also possible to directly connect the On-Air Light of the studio. Close. The Talk Box has a headphone amplifier with two 6.3 mm outputs. Via the two large illuminated buttons it is possible to activate and deactivate your own microphone (On/Off/Cough) or to switch on Talk back to the console.

Dante AoIP interface
Oxygen 2000 can be equipped with a Dante interface (compatible with AES67) that provides 8 stereo inputs and 8 stereo outputs on a dedicated Ethernet port, with independent level control and sample rate conversion.
On Oxygen 2000 Dante versions, the USB I/O ports are disabled.
The Dante AoIP interface is factory installed and must be requested during the order phase.
