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
• Idle Mic Attenuation
• Attenuation Attack Speed

USB audio I/O
2 Built-in stereo USB (Type-B) I/O Audio Interfaces allow to directly connect the PC to the Oxygen 1000 console, with no need for audio cards
In facts 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

Telephone Hybrid and Telco
The built-in telephone hybrid allows direct connection of a telephone line POTS/PSTN on RJ-11C. The audio is processed via DSP that delivers a state-of-the-art audio processing. It’s also available a Telco N-1 in/out, to connect Oxygen 1000 to an external telephone hybrid. The Telco N-1 is always available on RJ45. TLC commands are available on the same RJ45 with Hook and Ring interface.
TLC commands for Telco-2-5 are available and configurable on GPIO-DB9 connector with Hook and Ring.

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.
