D&R Airlab User Manual page 7

System Description
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 SiCo unit is a nice looking alternative with many extras 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
and the front panels are angled for visibility.
All similar functions in the triple input channels are color-coded with additional fader knobs available for
personalized channel color-coding.
Example:
Radio communication
On the basis that there's no radio without communication, the Airlab has extensive possibilities for
signaling and communications. 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.
NEVER CONNECT 115-230 VOLT LAMPS DIRECTLY TO THE ON-AIR SIGNALING OUTPUTS IN
THE MASTER SECTION!!
