  • Page 2 24 hours per day as an “On-Air” mixer and/or a production console in the most demanding production room. We are confident that you will be using the AIRENCE-USB mixer for many years to come, and wish you much success.
  • Page 3 INTRODUCTION MAIN MIXER UNIT The AIRENCE-USB MAIN mixer is designed as a 6 channel ON-AIR/Production mixer that can be expanded with one or more 6 channel extender units until you have sufficient inputs. There is no limit to the number of extender units because every unit has its own power supply and its own low noise summing amps.
  • Page 4 AIRENCE MAIN UNIT BACKPANEL The Main’s section back panel shows all the in and output connectors to interface with your other equipment. The first 1 to 4 MIC/LINE/USB modules on the right have balanced XLR mic inputs with a mic insert for voice processing.
  • Page 5 The low-noise design and excellent phase spec that D&R is known for is integrated through- out the AIRENCE-USB which results in a phase coherent signal path. Using balanced microphones & cables allows for the quietest and high quality audio signals throughout your AIRENCE-USB mixer. You can use standard balanced Mic cables available at any pro audio dealer or music store.
  • Page 6 10dB and choose for a unity gain position in the fully up position of the fader. A jumper setting page will be shown further in this manual to customize the AIRENCE to your needs.
  • Page 7 If your turntable only needs a pulse to start, ask your dealer. Or if you know how to temporarily remove the cover frame of the AIRENCE you can change a jumper setting to a momentary action, so it can be used as a pulse start switch.
  • Page 8 It is also advisable to make up you mind how you want the AIRENCE to do his job for you. Let me show you first a list of jumper settings and what you can achieve with changing the jumper settings.

  • Page 32 Introduction Besides the audio channels the Airence mixer is equipped with a control section. This control section is located at the right of the mixer and consists of 24 illuminated switches and a rotary encoder with push switch. The switches are able to illuminate red, green, and yellow to indicate various conditions.
  • Page 33 Communication Interface The present USB bus on the Airence mixer is used as the interface to transfer all the control signals to the PC. In order to keep things simple the HID (Human Interface Device) protocol is used for communication between the Airence mixer and PC.
  • Page 34 Controlling your software application In order to be able to control a software application (i.e. play out software) with the Airence control signals (control module / USB channel controls), one can choose one of the two available methodologies as can be seen in the figure below.
  • Page 35 Control signals In total there are 39 control signals coming from the Airence mixer which can be mapped to keystrokes using the Airence virtual keyboard mapper application. These 39 control signals are divided into the Control Module signals and USB Channel controls.
  • Page 36 Setting up your configuration The Airence virtual keyboard mapper application can be split up in an configuration editor and configuration viewer section as can be seen in the figure above. In the configuration editor section one is able to attach keystrokes to the control signals. To do so, clicking on one of the switches, encoder or faders opens up a keystroke configuration editor window where the configuration of the relevant control signal can be done.
  • Page 37 Play out plug-ins An play out plug-in is a set of function descriptions of a specific software application (play out software) which are mapped to keystrokes. A plug-in is represented as a standard XML-file which can be seen in the figure below. There is a plug-in folder PLUGINS created in the installation directory during setup where the plug-ins are located or has to be placed when creating one.
  • Page 38 Select one of the available functions from the Quick Function Learn box and press the Learn button. The window as seen in the figure below will show up and waits for a control signal event coming from the Airence mixer. If a control signal is received the selected function is immediately mapped to this control signal.
  • Page 39 When done with setting up the configuration the Virtual Keyboard Mapper application is ready to receive changes of the control signals from the Airence mixer. To do so, you have to press the START button in the Service box. If the application is able to con- nect to the Airence mixer the label on the button would change into STOP and the firmware revision of the mixer is shown.
  • Page 40 Airence mixer. For the communication between the PC (host) and Airence (device) the USB generic HID (Human Interface Device) class protocol is used. HID devices are identified by their PID and VID. For the Airence the PID=0x2402, and the VID=0x03EB.
  • Page 41 Write A message of the type WRITE is transmitted from the PC to Airence. The message is intended to perform an action on the Airence control section (i.e. illuminate a LED). If the action is correctly executed, the Airence will reply with a corresponding event.
  • Page 42 Description byte SIZE 0x02 Message size COMMAND 0x41 AIRENCE_FIRMWARE_VERSION_REQUEST Response A message of the type RESPONSE is transmitted from the Airence to the PC when prior a firmware version request message was received. AIRENCE_FIRMWARE_VERSION_RESPONSE byte: SIZE COMMAND PAYLOAD 0x04 0x81...
  • Page 43 Events A message of the type EVENT is transmitted from the Airence to the PC. An event will be generated when the state of a switch , encoder, or LED has changed. These events can be used to synchronize states of LEDs and switches between the Airence and the controlled application on the PC.
  • Page 44 Absolute encoder value [ 0 - 255 ] (wrap around) We hope to have given you some inside information about this control section of the AIRENCE and sure hope you will be happy with its performance to make your performance even better.

  • Page 47 2 Background USB System Architecture The USB System Architecture consists of the following main components: • Host (PC) Computer • One or more USB Devices • A physical bus represented by the USB Cable that links the devices with the host (PC) computer. 2.1.1 USB Host (your PC) The main responsibility of the host computer is to control the communication between the host system and USB devices.
  • Page 48 Due to the fact the Airence is a composite USB device consisting of four audio codecs, Control section, USB to Serial converter and USB Hub there is a lot of USB traffic between the Airence and your PC, if all individual components are used at the same time.

  • Page 50 To do so, a software program called ‘USB View’ is used here to visualize the USB tree structure in your system. With this tool you are able to check if the Airence is exclusively connected to a root hub. If not, you will see other devices con- nected to the same Root Hub.
  • Page 51 Therefore, the Airence does not need to share the USB bandwidth with other devices. To recognize the Airence device you can try to identify the internal USB Hub with the aid of the vendor- and product id’s, 0x0451 and 0x2077 respectively.
