    How does resistance affect the shock a person feels. A typical resistance between one hand to the other in "dry" condition could well over 100,000 Ohm. Always earth all your equipment by the grounding pin in your main plug. Proper wiring and isolation input/output transformers (optional) should only cure Hum loops. Oxygen 4 Digital...
  • Page 3 PRODUCT SAFETY Replace fuses always with the same type and rating after the equipment has been turned off and unplugged. If the fuse blows again you have an equipment failure, do not use it again and return it to your dealer for repair.
  • Page 4 We will certainly learn from your comments, and we will very much appreciate the effort and time it will take for you to communicate your idea’s and suggestions. We are confident that you will be using the Oxygen 4 Digital for many years to come, and wish you a lot of success.

    You can use this manual later on as a reference. In the first chapters we shall give you an overview of the Oxygen 4 Digital and its features. In this way you can have an impression of how to implement the system in your application.

  • Page 8: Contents Of The Package

    You can now also hook up the UTP cable to your ETHERNET 802.3 network if you would like to make settings. In chapter 10.5 you can find how to setup the Oxygen 4 Digital for networking. Connect the power supply cable to the 19" rack and to the wall outlet.

    PC. The Oxygen 4 Digital can receive an IP address via a DHCP server, or you can give a Fixed IP ! When this IP is known, you are able to connect to the Oxygen 4 Digital by software (HTTP web server or ActiveX object).

  • Page 10: Audio Signal Path

    5.1 Input matrix To give you the flexibility you need in your applications the Oxygen 4 Digital has a full matrix before processing takes place. You can assign one of your inputs to the eight modules in any way you want.

  • Page 11: Outputs

    For all Digital outputs you have a separate router which makes it possible for you too choose which buss is connected to the digital output. Due to the advanced routing matrix you also have the option to route any input directly to an output. Oxygen 4 Digital - from Axel Technology Phone +39 051736555, support@axeltechnology.com Page...

  • Page 12: Analog/Digital Levels With The Oxygen 4 Digital

    CD player to digital input 1 you can already set the headroom trim to -20 dB in the Global Settings dialog on the webpage. See also section 11.5. The Oxygen 4 Digital will then make a level correction for this medium (if assigned to a module/processing channel).

    HTTP, FTP, Cobranet etc… 7.2 The Layer Implementation For the Oxygen 4 Digital, we always use the Ethernet protocol for the Data Link & Physical layer. You can imagine this Ethernet protocol as an envelope. The information on the envelope is Source Address or Destination Address.

  • Page 15: Tcp/Ip Network Addressing

    Unfortunately, no one expected the Internet to grow as quickly as it did, and the limitations and inflexibility of this method of addressing were unforeseen. Adding another level to the address hierarchy, the subnet, helped to temporarily overcome many of these shortcomings.

    9.1.2 LINE inputs The Oxygen 4 Digital can connect 7 analog line inputs. The Input numbers 1-4 and 7 (front side) are stereo inputs. Input 5 and 6 are MONO inputs, with on the same connector a cleanfeed output, so these inputs can be used for a telephone-hybrid.

  • Page 22: External Inputs

    9.1.4 Program/Sub/Aux/CRM outputs The Oxygen 4 Digital is a very intuitive mixer which is very similar to analog mixing consoles. Therefore you also have all common outputs in the analog domain. That means you can directly hook up your equipment. Below you see a picture of the connections available.

  • Page 23: Digital Inputs/Outputs

    9.2 Digital Inputs/Outputs The Oxygen 4 Digital holds 7 digital inputs and outputs. At the rear side of the 19” rack you will find digital I/O 1-6 and at the front side is Digital I/O 7 located. The digital inputs at the rear side can receive either Coax (SPDIF) or XLR (AES3) digital audio.
