The D&R Airlab-DTon-air mixer is an extremely reliable solution for applications where features and functions has to be weighed up against operational simplicity. It's analog, digitally controlled signal path is the best solution of both worlds to achieve a reliable workhorse under any condition.
 
​A simple direct accessible control surface combined with intelligent instantly reset able digital functions enables customizing to station requirements and even to personal requirements because of the use of a personalized chip card holding all important functional data. The welded steel frame will accommodate a maximum of 16 triple input modules, which could include an unlimited number of Telco (or VoIP) modules (up to 16 of course) plus the master section with script space.
​
There is a Control Module available to control Play-out systems over USB and this module takes 2 positions. The main outputs are electronically balanced and the majority of connectors are on balanced XLRs.
 
input EQ
 
As the name suggests, the Airlab-DT triple input module combines a Mic input with two stereo line inputs. These could be analog inputs or AES 3 or USB inputs.  The mic input is electronically balanced. Apart from the gain control we have built in a front panel accessible trimmer to determine the mic gain range.
 
​A low cut filter can be activated by a jumper on the PCB. The mic input is located at the back of the console on female XLR connectors.  ​The Airlab-DT is equipped with linear 100mm faders controlling high quality "THAT" VCA's, another high end industry standard. Start can be activated with the fader or ON switch, depending which is activated first. Start can be software configured so that switching is from line A or line B. Similarly, the Cue switch is under software control avoiding impossible settings.
 
Telco
 
The AIRLAB-DT frame has thepossibility to be loaded with up to 16 Telco modules. Due to an ingenious Mix-Minus system, alignment is only necessary during installation. The AIRLAB-DT Telco module is a straight forward design making communication very easy.
 
The first control is the front panel accessible, R BAL trimmer for side tone adjustment, only necessary during installation. The Telco Send knob controls the outgoing signal to the caller. This signal is coming from the PROGRAM or SUB bus. The line input can be switched to a balanced XLR input connector to accept (eventually) an external (digital) hybrid instead of using its own internal hybrid. A separate input gain control with High Pass and Low Pass filters can be used to enhance intelligibility. The SUB and PROGRAM assign switch routes the signal to both outputs if needed.

VoIP
 
The Airlab-DT has the possibility to be loaded with VoIP modules. The R-BAL and TRIM are not present with a VoIP pc board built in.
 In case a VoIP module is installed one of the RJ-11 is replaced by 1x USB connector, the other RJ-11 has a clean-feed signal on pin 1 and 4. to be able to connect an external Analog or digital Hybrid to a land line or GSM Hybrid. When CUE is active in the VoIP module, the caller is connected to the CUE bus and also the engineers talk-back, but does not go ON-AIR yet as the fader is down. It is possible to connect both the Cue and On switch to a remote unit, allowing a director to control the broadcast.
​
Master Module
 
The master module is divided into three sections. The first “module” houses the TAPE SEND controls which selects the feed to the tape output. This could be either the SUB output signal or the AUX output signal. The Stereo Aux master controls the outgoing Aux signals from the input modules. A Talk-back to AUX switch is provided for.

The lower part of this “module” houses the Control Room Monitor section that can be fed by an EXT(ernal) stereo input, the stereo Aux output, a stereo ON-Air signal or the stereo SUB output signal. All selections have LED indicators and the lowest positioned switch has priority over the input selectors positioned directly above.

AES Module
 
The Airlab-DT has the possibility to have an optional AES output. When you choose for a AES-module(s), we will mount an digital male XLR outputs in Spare 2 and 3, giving you the Main Program output signal and Sub output signal on the backside of the console. ​Please be informed that this option needs to be mentioned in your purchase ad is an additionalcost
 
​USB Module
 
One USB connector is via an internal HUB connected to the USB modules, as chosen in your configuration. This USB connector also transfers the Meter data and all switch control data from the Control Module.

Control Module / Memory Chipcard
 
There is an optional Control section Module (2 positions) to directly control all the functions of your play-out system. Imagine 16 instant access buttons for jingles and/or station advertisements.
Scrolling through your play list, start and stop Music, Voice overs controlled from the mixer surface and many more free programmable functions for most play-out systems. A HID protocol is part of the delivery to program your own functions and pushbutton signaling. 
 
Chipcard
 
A specialty of the Airlab-DT is its ability to program all sorts of internal settings and then save it to a personalized chip card for instant reset. You can be program settings like; module set as DJ mic input, as Announcer mic input, as Studio mic input, Start/Stop plus Pulse/Continue per module, Cue start active, External remote, Timer start pulse per module and lots of more.
 
Master Outputs
 
All outputs receive the same signal that is selected by the input selection switches, or the Program output signal when no switch is activated. The Studio output has a mute LED indicator when the output is muted. All three outputs have a direct Talk back access switch for instant communication between control room and presentation area. The Cue bus is the main communication buss in the console. When a listener calls the station, by pushing the Cue switch of the Telco module you have him or her directly on the control room monitors.

Module Inputs
 
All Channel modules use the same input connector panel. XLR inputs are balanced except for the Cinch connector of course. The INSERT is for voice processors. The Start jack sends out signals from the fader/On start if the optional control module is present. In that case all control info is handled by the USB HID protocol. The REMOTE is for our Studio Remote unit to communicate insert is a mic insert that can be used for voice processors.
 
Software
 
The Airlab-DT sends out control signals over USB, based on the HID protocol. This also means that the main output signals can be displayed on a TFT screen in a beautiful meter application. Both Program and Sub stereo signals are shown on a high resolution PPM. A smaller separate stereo meter on the right hand side of the meter application shows all signals heard through the CRM speakers. At the same time this software application shows you a professional looking Radio clock that is synchronized with your local PC. 
 
The Airlab can also be configured in a custom format.
