MANUAL version 1.
Dear Client, Thank you for choosing the D&R AIRENCE-USB mixer. The AIRENCE-USB was designed by Radio Broadcast professionals along with the D&R design team and is intended to be used 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.
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. USB Module 1-4 • • • • • • • • • 4x Professional extremely low noise balanced Mic pre-amps with 48 volt phantom powering. Two pairs of line inputs Line and USB.
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. A start connector to activate red light signalling individually or this reed relay can be used to close (or pulse) a start contact to activate equipment connected to the line input. Two cinch connectors accept these line left/right input signals.
AIRENCE MAIN UNIT TRIPLE INPUT MODULES 1-4 The input modules switches & controls of the main AIRENCE mixer have the following functions: Each of Modules 1 thru 4 has three selectable inputs. The three types of inputs consist of a Microphone input a stereo line input and an USB input. In the Mic switch position, the module is a normal mono module.
CUE/COMMUNICATION BUSS Below the AUX SEND is the stereo CUE switch (Pre Fade Listening), this switch allows you to check the signal before you raise your channel fader up and mix it with other signals in the mixer. Another smart function is that this CUE bus can be used for communication. If you push a DJ’s Cue (let’s say channel one) and if you then push the Telco Cue, the DJ as well as the caller can hear each other outside the broadcast and even you, sitting behind the desk on the monitor speakers.
AIRENCE MAIN UNIT TRIPLE INPUT USB MODULES 1-4 INPUT CONNECTORS On the back of modules 1 thru 4, you find five connectors for each module. The stereo line input uses Cinch female type connectors. Being un-balanced, the shield and (-) or out of phase signal wire need to be connected together and seen as ground during installation. In order to use the START switch, it requires two pins in the ¼” stereo connector located on the back panel to be wired.
SPECIAL OPTIONS FOR USB MODULES 1 - 4 (PCB AIRENCE-2) Located on the input channel circuit boards are several jumpers that can be changed to enable different configurations of the USB Triple input channel settings. If changes are required, we advise you to contact your local dealer to have these changes performed. But if you know something about electronics and are not afraid to open up your mixer you can do it yourself. But... before you do anything power must be removed from the console of course.

SETTING UP THE USB MODULES Above pictured you see a section of the USB pcb where you can decide which output signal is sent to the USB connector. The default setting is PROG POST, it means a post master stereo fader signal is sent to the USB connector and to your PC. You can change this by moving both yellow jumpers two steps to the left, now you have a PROG PRE master fader signal to the USB connector. There are also options to get a signal from the Sub output or the AUX output.
SETTING UP THE USB MODULES In order to set up a connection between your computer and the AIRENCE-USB mixer, use a standard USB cable available from any local computer shop. (See picture). When connecting the AIRENCE-USB to your computer, the computer (PC or Mac) will recognize the AIRENCE as new hardware and will establish a connection to any audio programs needing audio hardware.
TELCO-LINE MODULE 1-2 CONNECTORS, CONTROLS, & FUNCTIONS Input modules Telco 1&2 have integrated Hybrid circuitry with built in high quality Telephone Hybrids as well as stereo line inputs in case only one Hybrid is needed. Highlights are: * High quality Telephone Hybrid circuit to directly connect to phone lines. * Stereo line input. * Gain control. * Telco send Control. * Direct access CONNect and TB (Talk Back) switches. * Stereo Aux send. * Stereo CUE switch for pre fade listening.
AUX SEND Below the TB switch is the stereo Aux send that can be set to send stereo source signals pre or post fader (pre or post jumper settings on the circuit board). The factory default is post fader. ROUTING Each input module has SUB and PROG(ram) routing switches to route the stereo signal to either the SUB bus, Program bus or both at the same time, or... not at all. CUE Next you will see the stereo CUE switch (Pre Fader Listening).
SPECIAL AVAILABLE OPTIONS IN YOUR AIRENCE-TELCO MODULE On the PCB of your TELCO AIRENCE module there are several jumpers and 2 trimmers that can be changed/trimmed to enable different configurations of the channel settings. This should be done by a D&R dealer, service center or yourselves if you are not afraid of electronics and screwdrivers. But... be sure to remove the mains cable(s) first!! The following 3 jumper settings can be changed to adjust the AIRENCE Telco modules to your needs.
AIRENCE MASTER SECTION The AIRENCE master section houses all the controls for the mix buss Program faders and master controls for Aux return, EXT (2-Track) play-back, and master outputs. Individual functions are described below in sections as shown on the front panel below. LEDBAR METERS The master section has two high-res 11 segment LEDbar meters with VU meter Ballistics. Depending on which switch is pressed (CUE on channels, AUX SEND master, SUB, AUX RET, EXT, etc.
STUDIO The AIRENCE has a separate Studio output that normally follows the Program pre-fader left and right signals, but in case a guest wants to hear a caller switching to Follow Phones enables him or her to listen tot the CUE system and to communicate with the caller outside a broadcast. You can connect the inputs of reverbs from these outputs (with Aux send jumpered to post fader) or use them as a monitor output, after you jumper the Aux send in the channels to pre fader.
TALK BACK The Talk back circuit has a built in electret microphone with routing to most of the outputs. By selecting one or more of the routing switches, you can communicate to the outputs SUB/AUX/STUDIO and Announcer. The Talk back level is independent of settings of the master controls and Announcer outputs. An exception is the AUX output, here the Talk back level is also dependant upon the master level setting of the AUX master.
MASTER BACKPANEL CONNECTORS The master connector panel houses 18 RCA/Cinch connectors, 2 jack sockets, and 2 male XLR connectors. There are two power supply connectors, USB connector and the SUB-D type connector to connect a slave unit to the main unit. From right to left we will describe the functions and features of the master connector panel. AUX SEND The aux outputs are on two RCA Cinch connectors with the signal coming from the aux send controls in the channels. The level is +6 dBu (1.55 volt).
ANNOUNCER OUTPUT The Announcer output is on a Stereo jack connector and carries the signal coming from the Program Announcer amps. This output can be used for sending signal to the announcer in the Studio. Normally this output carries the main program signal unless the follow phones push button is activated, then the announcer can be linked to Cue signals for communication with DJ’s and or Callers.
MASTER OUTPUTS The master outputs are 3 pin male XLR connectors and are electronically balanced and can be connected to an input of a power amp, professional recorder or On-Air processor. The output level is +6 dBu (1.55 volt). POWER CONNECTOR These two 5 pin XLR connectors accept external 36 volt 5A switched low energy power supplies that are part of the delivery. DO NOT USE ANY OTHER POWER SUPPLY THEN THIS ONE!!! Your AIRENCE can accept voltages between 90 AND 230 volts at 50/60Hz.
SET-UP ROUTINES MODULE 1-4 • • • • • • • • • • • • • • Connect a power-amp, recorder, or transmitter to the Master left/right main outputs. Connect a high impedance (NOT BELOW 400 Ohm) headphone to the “phones” jack socket on the master section. Connect a microphone or line level equipment. Now, connect turntables, CD players, and jingle machines. Connect a red light indicator to the master section when there is a need for it.
SETTING UP THE TELCO MODULES Connect the two wires of the telephone line’s wall connector to the RJ-11 connector labelled wall (LINE) and connect the telephone unit (the one that has a dialer and handset) to the RJ-11 connector labelled PHONE. Note that to originate calls, a local phone must be connected to the AIRENCE, so you are able to dial a number. Once the dialed person has taken the call you can talk to him via the handset and inform him that he will be in the broadcast soon.
CONNECTION WIRING OF BOTH (Wall) LINE and PHONE RJ-11 CONNECTORS PHONE/WALL RJ-11 FUNCTION CONNECTION Pin 1 n.c. Pin 2 A (telephone line) In/out Pin 3 B (telephone line) In/out Pin 4 n.c. Below is an explanation for Germany Phone systems where different telephone connectors are used.
EXTENDER TRIPLE INPUT MODULES 1-6 The input modules switches & controls of the main AIRENCE-EXTENDER mixer have the following functions: Each of Modules 1 thru 6 has three selectable inputs. The three types of inputs consist of a Mic input a stereo line input and a second Stereo LIne input. In the Mic switch position, the module is a normal mono module.
ON The ON switch is used to activate the module and generate a start signal for turntables, CD players, and jingle or cart machines. This switch sends out a momentary pulse or shortens continuously two pins of the Start connector on the back panel of the console. A jumper setting on ther PCB let’s you choose between pulse and continuously. FADER Final control is the high quality, 100 mm long throw K-Alps stereo channel fader with integrated fader start switch.
INSERT This ring/tip/sleeve stereo jack socket let’s you insert signal processors such as compressors/gates or special voice processing units to improve your voice to sound like the ultimate announcer/D.J. The Ring of the stereo jack sends the channel signal and the Tip accepts the return signal. On the right you see the type of cable you need when your processor has jack in and outputs.

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. Each switch contains a label which can be customized to customer needs.
USB channel controls Furthermore, the fader start, on and cue signals of the four available USB channels in the Airence mixer could also be used to trigger or control any software application. In combination with the control module the Airence mixer provides a flexible all-inone solution to manage and control specific play out systems. Figure 2.
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. The first method is most applicable for software developers of the controlled application, who are able to integrate the Airence USB HID Control Protocol in their application.
Airence virtual keyboard mapper The Airence virtual keyboard mapper is a software application which maps incoming control signals from the Airence mixer to keystrokes by creating a virtual keyboard on a windows machine. Since the mapper application behaves like a real keyboard it is able to control any software application which is controllable by a keyboard. Most software applications have attached keystrokes to file menu items or application specific functions.
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.
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. Present plug-ins in this folder are loaded when Virtual Keyboard Mapper is starting up.
Figure 7. Keyboard keys vs. ID Quick function Learn The Quick Function Learn is a feature to map control signals to play-out functions rapidly. First you have to select a play out plug-in before the quick function learn can be used. If the play out plug-in is loaded correctly, the loaded functions are listed in the Quick Function Learn box. Figure 8.
Configuration viewer In the configuration viewer section an overview of the entire configuration can be seen. All the pressed and released events of the control signals are shown in the Virtual Keyboard Mapping area.
HID Control Protocol for software engineers Introduction This chapter describes the protocol which is used to communicate with the control section and the USB channel controls of the 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.
MESSAGES 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.
AIRENCE_FIRMWARE_VERSION_REQUEST byte: byte 0 1 0 1 2 3 4 5 6 SIZE 0x02 COMMAND 0x41 PAYLOAD Symbol SIZE COMMAND Value 0x02 0x41 Description Message size AIRENCE_FIRMWARE_VERSION_REQUEST 7 Response A message of the type RESPONSE is transmitted from the Airence to the PC when prior a firmware version request message was received.
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.

TROUBLESHOOTING ‘USB Controller bandwidth exceeded’ in Windows 7 Version 1.
1 Table of contents 1 TABLE OF CONTENTS 2 BACKGROUND 2.1 2.1.1 2.1.2 2.
2 Background 2.1 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.
USB Hub USB Hub is just a device with multiple USB ports for plugging in the USB devices and other hubs. The Internal root hub in the host (PC) controller and the external hubs are functionally the same. 2.
Figure 2. Windows 7 generates warning message Figure 3.
4 Solution Figure 4. Connect the Airence exclusively to the Root Hub In order to prevent the bandwidth overload, simply make sure the Airence is exclusively connected to a Root Hub (see figure above). 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 connected to the same Root Hub.
In the example below you can see the Airence is connected to the first port (LOC21) of a 2-port roothub. There is no device connected to the second port (Loc22). 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. Try to connect to another usb port on your PC if the Airence shares a Root Hub with other devices. Figure 5.

Introduction Every now and then new firmware versions will be released to provide the Airence mixer with new features or solved bug fixes. In order to be able to update the current firmware residing in the Airence mixer a special operating mode called ‘bootloader mode’ must be entered to receive new firmware. When powering up the mixer in an ordinary way it will enter the normal operation mode and is ready for use.
- Select a destination location for the update tool to be installed into and click Next. - Select a start menu folder and click Next.
- Enable the ‘Create a desktop icon’ for a shortcut on the desktop and click Next. - If you agree with the configuration click Install to begin installation.
- Setup copies files to the destination install folder. - Click Finish to complete the installation.
USB bootloader drivers When the Airence mixer enters the bootloader mode it will probably sign up as an ‘unknown device’ in the device manager from Windows. To determine if this unknown device is the Airence in bootloader mode, right-click on the device and select properties. On the Details tab select Hardware-id’s from the properties selection box and verify the VID and PID of the device.
If the installation of the drivers was successful you should be able to see a screen similar to the one below: In the device manager the unknown device is correctly installed and now shown as : ATxmega32A4U The ATxmega32A4U device indicates the Airence is in bootloader mode.
Firmware Update Procedure Preparation Before you can start with the update procedure the following precautions must be taken: - Connect a USB cable between the Airence mixer and the PC - Startup the Airence mixer in bootloader mode - Download the latest firmware from www.d-r.nl (e.g. airence_firmware_v1_4.zip) Flash firmware into device - Startup the Airence Firmware Updatetool application. - Select the firmware (*.hex) from the extracted zip-archive downloaded from the website.
Troubleshooting Firmware update failed If you get the following error after pressing the UPDATE button you should check if the Airence mixer is properly connected with a USB cable and if the device is in bootloader mode.
