SYSTEM DESCRIPTION D&R Quality D&R has been the largest manufacturer of mixing consoles and signal processors in the Netherlands for 42 years. More than 90% of the total production is exported worldwide. This market demands excellent pricing and quality standards. D&R products are used in studios and live performances, both of which require 100% reliability, which is the result of 42 years of research, design and manufacturing. These high standards of reliability are also to be found imbedded in the new line of broadcast mixers, which is particularly important for this type of product, required to work around the clock. Airlab-DT Quality The high standard of quality of the Airlab is demonstrated by the welded steel RF screening and sturdy housing, the heavy duty power supply, its modular approach and locking IDC connectors mounted on high quality double sided, plated through, glass epoxy printed circuit boards. The signal paths are electronically switched using CMOS logic and ‘FET’ components, ensuring reliable and smooth switching. High quality 100mm faders control the new redesigned “THAT” VCA’s. Switching is performed by isolated encapsulated reed relays guaranteeing many years of trouble free smooth switching. Airlab-DT flexibility The Airlab is a specially designed production/ On-Air broadcast console. Although the design has been carefully budgeted, no compromises have been made in either quality or features, particularly in the areas of VCA control, switching, signaling, fader start/stop and communication. The Airlab is fully modular, which means flexibility in the configuration. The Triple input modules (with ot without EQ), the USB modules and digital modules as well as the Telco input modules can be placed anywhere in the chassis. A partially loaded Airlab can be fully filled with ‘blind modules’. Digital programmable Most of the important module functions such as module set-up as well as overall master settings are programmable and can be saved on a personal memory card or in the internal memory of the Airlab. The LCD in the master section helps you with the programming. There is also a possibility to do this on your PC by connecting the Airlab to your PC by way of a RS232 (Airlab side) to USB (PC side) cable set that is part of the delivery. The Airlab is a complete and self-contained piece of hardware, requiring no additional items in order to be operated. All relevant functions are built-in, such as fader start/stop (pulse or continuously selectable). There is also no need for complex mic-on/cough switching to the announcer booth. A stereo jack, a LED and a simple push-button switch complete this task. The optional Studio Remote is a nice looking drop through contgrol un it for Cough switching and monitoring. Built-in stereo headphone amp The Airlab contains built-in headphone amps for the Announcer and Guests. No additional amps are needed. The Studio output needs to be hooked up to a power amp that can handle +6 dBu as nominal level for full power. Clear layout To create a clear layout most of the switches have LED indicators, large CUE/SELECT and ON switches. All similar functions in the triple input channels are color-coded, additional cur coded fader knobs are available for personalized channel color-coding. Example: Microphone channels: red fader knobs Telephone channels: gray fader knobs Stereo channels: black fader knobs Radio communication There’s no radio without communication, so the Airlab has extensive possibilities for signaling and communication. Every microphone channel has its own signaling and talk back circuitry and all outputs can also be connected to the talk back circuitry. The announcer/technician/producer/director can communicate with the announcer booth, guests, monitoring system, all connected Telco modules and auxiliaries, either individually or in any combination. A very intelligent CUE system connects every activated CUE switch with each other to create a transparent and intuitive communication system. It will be explained in detail further in this manual. Signaling It is extremely important in broadcast to know whether a microphone channel is active. Every channel has a red light signaling available on the remote connector. The Airlab has two external connectors for ON-AIR (mic-on) signaling to control external relays activating high voltage ON-AIR lamps or the D&R ON-AIR led light that does not need any additional circuitry to function. keep that in mind. NEVER CONNECT 115-230 VOLT LAMPS DIRECTLY TO THE ON-AIR SIGNALING OUTPUTS IN THE MASTER SECTION!! Page 5 Broadcasting Options In designing the Airlab, D&R decided to make the system as flexible for the operator as possible, therefore the Airlab can be used in many ways. There’s a minimum of jumper settings, which can be set to suit your own needs. Most of the settings are under software control in the master section and can be stored to a chip card. The Airlab can be used in a traditional manner with separate control and announcer rooms, or in a more open way, whereby announcing and engineering control are carried out in one room. A self-op setup or a combination of several setups is possible. More than one Broadcast Studio There are numerous monitor facilities in the Airlab for external sources as well as internal sources. The control monitors (and software meters) can be switched to follow the control room for separate (stereo) sources. These features mean that the Airlab is specially suited to work in a studio-complex environment, where there is more than one studio/control room being used for broadcast. In this situation, the Airlab is capable of being the main On-Air console due to the two main outputs it contains. These main outputs can be fully transformer balanced as an option. Special Recording Outputs The Airlab has a special Recording output on a 0dBu output level. Double Stereo Software Peak Metering application In order to achieve a good balance between spoken words and music, it’s important to be able to read the recording level accurately. The Airlab has as standard 4 Peakreading software meters reading per pair the Program output, the Sub output and the CRM output. SUMMARY Whilst using the Airlab, you’ll discover its many hidden features, and will continue to appreciate its extensive capabilities. Page 6 4. TRIPLE
