4 AIRLITE BACKPANEL

The back panel shows all the in and output connectors to interface with your other equipment.
The first 1 to 3 MIC/LINE modules on the right have balanced XLR mic inputs with a mic insert for voice processing.
A Remote (Cough/Comm) connector to activate the internal Cue and ON switch for coughing and communicating.
Two cinch connectors accept line level left/right input signals.

Modules 4-5-6-7 are the USB inputs that are fed from a built in USB HUB that accepts and sends stereo sends signals to a con­nected PC where a music play-out systems could be active.

There are also stereo line inputs available on Cinch connectors per input 4-5-6-7.
below the Line inputs you can see 2 GPO (General Purpose Output) jacks that can be assigned in the software to function as
signaling of ON-AIR 1 or 2, Phone. Mic ON, Non-Stop or module active (start).

Below Module 6 and 7 connectors there are the USB connectors, one for the audio (USB MAIN) and the other for the VoIP con­nection. The USB Main connector carries all the 4 stereo audio signals to and from the PC (for both Windows & Macintosh com­puters) as well as the Play-out systems control info from the programmable Control section plus the Clock and meter informa­tion. This USB feature will allow to connect to the Internet via your computer for “Live” streaming of audio to the Internet.

Module 8 (the VoIP) module has as extra a stereo line input for external (analog) Hybrids and cleanfeed outputs to drive these
external Hybrids incase a VoIP connection is not available or not yet installed.

4.1 MASTER CONNECTORS

The master section houses all the in and outputs of the controls on the front panel that we go into detail in other chapters.
Most of the functions are self-explanatory, such as master right and
left XLR’s and all the other in and outputs.

In detail it means that you see from left to right the cinch AIR inputs
to return an external off air tuner or an Internet return.
Below the AIR INPUT you see the CUE output that can be routed to
an external speaker.
Then there are the AUX send and returns and CRM output.
Apart from the master balanced XLR outs there is also a -10dBV

master outputs on cinch connectors.

Below Module 8 you see a Master AES/EBU XLR that can send out a
digital main program signal if you have ordered that option.

Worth mentioning is the heavy duty external power supply that accepts voltages between 90 en 230 volts AC.

5 MIC / LINE INPUT MODULES 1-3

The input modules switches & controls of the AIRLITE mixer have the following functions: Each of Modules 1 thru 3 has two
selectable inputs. The two types of inputs consist of a Microphone input and a stereo line input. In the lower Mic switch
position, the module is a normal mono module. When the Mic is switched out(up position), you also have a stereo line level
input to feed the stereo AUX send, PROGRAM buss, CUE buss and Voice Tracking buss.

14

5.1 GAIN

With the gain control (the first control knob below the modules number), the source input level can be
adjusted to the required internal mixer level. This control adjusts both the Mic input and the stereo line
inputs with the same control depending on the switch position. There are AUX jumper settings in the
console, so we advice to make a (jumper)plan for your situation and then do all the internal jumper
settings in one go. Or tell us through your dealer how you want the jumpers selected and we deliver the
console as requested.

5.2 STEREO LINE

The stereo line input is a high impedance input ( >10 kOhm) for connecting the stereo line level outputs
of devices such as CD players/MP3 players etc.

5.3 MIC

The Mic input has a balanced XLR input connector with 48 volt phantom powering for condenser mikes.
The Mic-pre circuitry uses the latest technology studio-class components as used in high end record-ing
consoles, we use the That 1510 Mic-pre which is highly acclaimed for its low noise/distortion and
transparent audio. The low-noise design and excellent phase spec that D&R is known for is integrated
throughout the AIRLITE which results in a phase coherent signal path. Using balanced microphones &
cables allows for the quietest and high quality audio signals throughout your AIRLITE mixer. You can use
standard balanced Mic cables available at any pro audio dealer or music store. The AIRLITE uses chassis­mount female XLR type Mic input connectors. Any standard pro audio Mic cable will fit into this female
XLR connector.

5.4 EQUALIZER

Each module has a stereo three band equalizer to control the high, mid, and low frequencies individually.
The D&R designers used carefully chosen frequencies in the equalizer circuitry to enhance the Mic input
as well as the stereo line input.

5.5 AUX SEND

The next control is a stereo Aux send that sends stereo source signals to the stereo Aux send buss Master
and then to the output connectors on the Master back panel. The stereo Aux send is for external effects
such as reverb, echo or headphone amplifiers. Each Aux send can be set pre or post fader by changing
jumper settings on the circuit board of each module. The factory default is post fader.

5.6 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 out- side the
broadcast and even you, sitting behind the desk on the monitor speakers. Note: Levels need to be
carefully set to avoid feedback and overdrive of circuits. The Cue switch also sends out HID signal over
USB that can be programmed to do specific functions in your play-out system.

5.7 ON

The ON switch is used to pass on the audio. The ON switch also sends out HID signal over USB that can be
programmed to do specific functions in your play-out system. In the Control section of the manual we
will explain how.

5.8 VOICE TRACK BUSS

The ON switch is ALSO used to route an input signal from module 1-3 to the Voice track buss.
Push the ON switch a little bit longer and the audio will be removed from the Program buss and assigned
to the Voice track buss, as a result the ON switch will blink. The Voice track signal Is routed to USB-3 for
further processing in your play-out system.

5.9 FADER

Final audio level control is the high quality, 100 mm long throw N-Alps channel fader that send out a

15

control voltage to the in-ternal stereo VCA. The control voltage is also used to detect when the fader is moved up and can send
out a pulse for fader start purposes. This control voltage activates the start circuitry that can be assigned to one of the two GPO
connectors.

In the software set up there is an option (fader Dynamics) where you can select if you want and extra 10dB of fader gain. Then
the unity gain position will be at the -10dB position. If you are a person that sweeps the fader fully up and down, then do not
select the extra fader gain of 10dB and choose for a unity gain position in the fully up position of the fader.

A software page (as already seen below) will be shown further in this manual to customize the AIRLITE to your needs with
instructions how to do that.

16

5.10 INPUT CONNECTORS

On the back of modules 1 thru 3, 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 internal Remote switches, it requires a ¼” stereo

jack plug connected to the Remote connector located on the back
panel.

Or you can activate a function in your play-out software by USB HID
instructions that will be explained later in the USB CONTROL section
of the manual.

5.11 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 PRE-FADER 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. Connect the tip from the
stereo cable to the tip of one of the mono jacks and the ring of the stereo cable to the tip of the other mono jack.

Now insert the stereo jack into the AIRLITE’s insert and connect the mono jack that produces a hum when the tip is touched by
your finger (and the related channel fader is open) into the processors output. The other mono jack should be inserted into the
processors input.

In case your processor has XLR inputs connect the tip of the stereo jack to pin 2 of the Female XLR and short pin 1 and 3 with
each other and connect to ground (sleeve), this also goes for the other Male XLR, connect the ring of the stereo jack (which
sends signals) to a male XLR pin2. Short here pin 1 and 3 and solder to ground (sleeve). This has to be done because the insert
is not balanced.
See below the cable type you need.

5.12 MICROPHONE INPUT

The Mic input is a balanced female XLR type connector., see the left connector below that should go into your mixer and your
mic cable should end in a male XLR as seen on the right section of the picture.

1=Ground/shield
2=Hot (in phase)
3=Cold (out of Phase).

17

5.13 SPECIAL OPTIONS

Located on the bottom of the circuit board there are several jumpers that can be set to enable different configurations of the
Mic/Line modules as well as the other modules.
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. The metal cover frame must be removed

to be able to reach the modules jumpers. This is something you need to do only once before installation.

5.14 HOW TO REMOVE THE BOTTOM OF YOUR MIXER

First remove the 3 bolts below the faders that hold the cover, then put the mixer upside down on a soft surface.
You see on the back panel side of the cover again 3 bolts that needs to be removed.
Also on the left and right side of the frame there are 2 bolts that needs to be removed. Once
you have done this you can lift the cover from the front and the back panel of the mixer. Use
a tweezer to lift and replace the jumpers.
It is also advisable to make up you mind how you want the AIRLITE to do his job for you.
Most of the settings are ij software but in hardware you can selct of you want the AUX send to receive its signal pre or post
the channel fader.

Below is a photo what you can expect when you open up the mixer.
You see 8 sets of jumpers to change the pre-post selEction of the AUX sends.

18

6 USB / LINE INPUT MODULES 4-5-6-7

The input modules switches & controls of the AIRLITE mixer have the following functions:
Each of Modules 4 thru 7 has two selectable inputs. The two types of inputs consist of an USB input
and a stereo line input. In the lower USB switch position, the module is a stereo module. When the USB
is switched out(up position), you also have a stereo line level input to feed the stereo AUX send,
Master buss, Cue buss and Voice tracking buss.

6.1 GAIN

With the gain control (the first control knob below the modules number), the source input level can
be adjusted to the required internal mixer level. This control adjusts both the USB input and the
stereo Line inputs with the same control depending on the switch position. There are AUX jumper
settings in the console, so we advise to make a (jumper)plan for your situation and then do all the
internal jumper settings in one go. Or tell us through your dealer how you want the jumpers selected
and we deliver the console as requested.

6.2 STEREO LINE

The stereo line input is a high impedance input ( >10 kOhm) for connecting the stereo line level
outputs of devices such as CD players/MP3 players etc.

6.3 USB

The USB stereo signal comes directly from one of the 4 stereo USB channels from your PC play-out
soft-ware. These are already assigned in the Mixer to module 4, 5, 6 and 7 by D&R.

6.4 AUX SEND

The next control is a stereo Aux send that sends stereo source signals to the stereo Aux send buss
Master and then to the output connectors on the Master back panel. The stereo Aux send is for external
effects such as reverb, echo or headphone amplifiers. Each Aux send can be set pre or post fader by
changing jumper settings on the circuit board of each module. The factory default is post fader.

6.5 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 out
side the broadcast and even you, sitting behind the desk on the monitor speakers.
Note: Levels need to be carefully set to avoid feedback and overdrive of circuits.
The Cue switch also sends out HID signal over USB that can be programmed to do specific functions

in your play-out system. In the Control section of the manual we will explain how.

6.6 ON

The ON switch also sends out HID signal over USB that can be programmed to do specific functions
in your play-out system. In the Control section of the manual we will explain this how.

6.7 FADER

Final audio level control is the high quality, 100 mm long throw N-Alps channel fader that send out a
control voltage to the internal stereo VCA. The control voltage is also used to detect when the fader
is moved up and sends out a pulse for fader start purposes.

In the software set up there is a setting where you can select if you want and extra 10dB of fader gain.
Then the unity gain position will be at the -10dB position. If you are a person that sweeps the fader fully
up and down, then do not select the extra fader gain of 10dB and choose for a unity gain position in the
fully up position of the fader. A software page will be shown further in this manual to customize the
AIRLITE to your needs with instructions how to do that.

19

6.8 SETTING UP THE USB MODULES

Actually there is not so much you can do concerning routing of the incoming USB signals. The ON switches connect the incoming
stereo signals sent by the play-out system 1-4 to channel 4,5,6 and 7. The routing inside the PC software is done automatically
and described in more detail below. In the Block diagram (in the brochure and in this manual) you can see that the mixers USB
output signal 1 (all stereo) is the program signal and sent to the USB-1 buss. It is a PROG POST signal, it means a post channel
stereo fader signal is sent to the USB connector and to your PC.

6.9 USB OUTPUTS

There are 4 stereo USB signals sent to you PC through the USB connector on the back of your console.

USB-1 = Main program signal.
USB-2 = AUX output signal
USB-3 = Voice track signal
USB-4 = (off) AIR signal
USB-5 = VoIP signal (has its own USB connector)

An audio application needs to run on your PC to be able to see the levels. Or else trial and error is
the only way. A free downloadable tool is to be found here

http://minorshill.co.uk/pc2/testgen.html

The return USB signal coming from the PC is fixed but can be adjusted with the AIRLITE modules Gain controls.

6.10 SETTING UP THE MODULES

In order to set up a connection between your computer and the AIRLITE-USB mixer, use a standard USB cable available from any
local computer shop. (See picture). When connecting the AIRLITE-USB to your computer, the computer (PC or Mac) will
recognize the AIRLITE as new hardware and will establish a connection to any audio programs needing audio hardware. After
establishing a connection, there is no need to download drivers or performing complicated setup routines, just plug in the USB
cable to your Windows or Mac computer and start tracking! (or playing a maximum of 4 stereo channels at the same time). If
you want to know more about USB try this linkhttp://en.wikipedia.org/wiki/Audio_Stream_Input/Output

If you are already familiar with digital audio recording, the latest versions of Kristal Audio Engine and Audacity are available free
of charge via the Internet. Use this link http://www.asio4all.com/ for third party downloads.

7 VOIP / LINE INPUT MODULE 8

Input module 8 is a dedicated Voice over IP Telephone module and also has a stereo line input in case
a classisc Hybrid is needed.
Highlights are:

* High quality Telephone Hybrid circuit to directly connect to the Internet.
* Stereo line input.
* Gain control.
* VoIP/Telco send Control.
* Direct access CONNect and TB (Talk Back) switches in the master section.
* Stereo Aux send.
* Stereo CUE switch for pre fade listening.
* Start (ON) switch and 100mm smooth professional fader.

7.1 WHAT IS A TELEPHONE HYBRID?

Telephone hybrids are hardware interfaces between professional audio equipment and public telephone
networks. They provide protection for your equipment and the public telephone lines, allowing for vari­ous line signals and line conditions. Automatically canceling out the unwanted signal, they facilitate two­way communication when using a single 2 wire telephone line. An AIRLITE VoIP module has a USB VoIP
connector and a stereo line in cinch connector to return a classic analog or digital Hybrid that are used in
radio and television broadcasting facilities around the World allowing external callers to be connected to
the studio mixer for live broadcast. Many of the D&R Telephone Hybrids are supplied to radio stations al­lowing extremely effective conversion between 4-wire audio circuits and standard 2 wire telephone lines.

7.2 VoIP CHANNEL

In the AIRLITE we have built in an interface that let you connect to the Internet community by way of
(for instance) Skype. Skype is freely available communication software that can be used to call and
receive calls of your listeners to your broadcast station. We have designed a separate USB connector on
the backpanel of your console to interface with SKYPE software. This could be on the same PC (on a
second USB connector) as the Play-out system is installed or on a separate PC for dedicated use of the
VoIP chan-nel with SKYPE software. For downloading the SKYPE software go to http://www.skype.com
and then to your own language for more support. There are some SKYPE software settings you need to
go through before this is working with your console. For some usefull instructions go to:

https://support.skype.com/nl/faq/FA34541/een-perfect-skype-gesprek-voeren

(Dutch instruction video, but I am sure there is one in your own language or in English of course).

7.3 GAIN

With the GAIN control, the source level is adjusted to the internal mixer level.
This is for both the VoIP and the Stereo Line input (when selected)

7.4 LINE / VOIP INPUT SWITCH

When switched to the VoIP position only the VoIP signal is received. When this switch is up, you have a
high impedance stereo line level input for connecting an external Hybrid or... cart machines, iPods, tape
machines, CD players etc.

7.5 VOIP SEND

With this level control the outgoing signal from the mixer is sent to the caller via Skype or and via
an external connected Hybrid. This is for both the VoIP and the Stereo Line input (when selected).
This Hybrid get’s it send sighnal from the cleanfeed output on the back of the console. .

7.6 CONNect

This switch (when pushed) picks up the VoIP/Hybrid signal when a call comes in. Note: the incoming
call will not be heard until the CUE is pressed or the ON switch and the fader are activated which
brings the signal to the mixer. You can of course have a handset with dial possibility to dial and pick up
calls from the caller first before you connect the caller to the mixer by pushing the CONNect button. To
hear the caller you have to push the CUE button and to bring the caller on-air push the ON switch and
pull up de fader.

21

7.7 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.

7.8 CUE

Next you will see the stereo CUE switch (Pre Fader Listening). This switch allows you to check the
signal before you mix it with your other channel signals in the mixer. A second very important function
is that this Cue buss is also designed to be a N-1 communication buss. It means that a caller hears any
signal connected to this Cue buss except his own signal. So communication between a DJ channel and
the caller is possible without having to mix in the DJ channel and the caller in the broadcast.

7.9 ON

The ON switch is used to activate the module. There are 3 colours that you can choose from in
different states of the ON switch.

On Active = red, green or off
On+Fader Active = red, green or off
On not active = red, green or off

7.10 FADER

Final control of the channel is the 100mm long throw N-Alps channel fader with integrated fader start
function. The channel fader sends the amount of signal from the associated channel to the master mix
buss. There is no Audio going through the fader, just a DC control signal driving a stereo VCA, so fader
noise will never happen in this design.
At the right side of the fader you see a dB labelling starting at the top with no attenuation (0) and sliding
down it attenuates in steps of 5dB until it reaches a full cut off below -90dB. When you are used to fully
throw the fader in its top position when opening a channel it is advisable to set the fader gain software
setting to 0dB (factory default). If you need a little bit of “playground” for your audio, set the software­jumper to +10dB fader gain and see the -10dB (10) position as your unity gain position.

7.11 INPUT CONNECTORS

On the back of each of the AIRLITE VoIP module you find four connectors. Two unbalanced stereo line
RCA Cinch connectors for connecting CD players, iPods, or any play-back devices as long as they are line
level equipment. The level can be set using the gain control to match most source levels. The left RCA/
Cinch connector is the right input and the right RCA/Cinch connector is the left input. The shield needs
to be connected to the ground or case of the RCA/Cinch connector.

The two unbalanced stereo line RCA Cinch connectors labelled CLEANFEED can be used to connect
the Module to the input of an external connected Telphone Hybrid such as D&R’s Hybrid-1 or 2 or
the TELCOM unit. The output of the Hybrid should be connected to the stereo line input to return
the signal from the caller into the mixer. For adjustments follow the manual of the Hybrid.

A cleanfeed sent signal (presented on the back of this module) is a mix of all
signals that are present in the mixer except the signal that is processed in
this
VoIP channel to avoid feedback.
In case you use a classic Telephone Hybrid to connect with your listeners,
separate telephone equipment should be used to dial the caller and
interface with the landline telephone system.

22

8 MASTER SECTION

The AIRLITE master section houses all the controls for the outgoing signal and communication signals. Individual functions are
described below in sections as shown on the front panel on the right.

8.1 LEDBAR METERS

The master section has two high-res 16 segment LEDbar meters
with peak reading ballistics. This means an attack time of 10 mSec
for every 20dB and a fall back time of 1.5 seconds for every 20 dB.
Depending on which switch is pressed (CUE on channels, master
AUX SEND Cue, CUE AIR, CUE NON STOP, the master meters will
allow the reading of all in- and outgoing signals. The attack and
release time constants are conform to International PPM
standards, being 10 mSec for attack and 1.5seconds (pr20dB) for
decay. The green area of the LEDbar is the safe area and
occasionally a red led on is no problem. The output level of your

AIRLITE is designed to be +6dBu (1.55v) (“0” VU) when the 0 green

LED is on.

8.2 NONSTOP

The Non Stop switch is a very convenient function when you want
to use your mixer while you are NON STOP on-air. By activating this
switch USB channel 1 sends its signal directly to the master XLR
outputs, making your mixer completely free for produc-tion. A CUE

ns switch let’s you listen to what you’re broadcasting directly out

of your Play-out system. Two Trimmers are available to even out
any level differences between NON stop mode and On-Air mode to
make a convenient switch be-twen these two modes.

8.3 CUE NS (NON-STOP)

The CUE-NS switch allows for checking the outgoing signal to the
master outputs when the NON STOP switch is active.

8.4 AUX SEND

The stereo AUX SEND master controls the sum of the entire
individual stereo Aux send signals coming from the input channels.
A Cue button let you hear what is on the Aux send buss in stereo.

8.5 AUX RETURN

This stereo input is intended to be used for returning the stereo out­puts of reverbs or other effects gear and can be routed to the Pro­gram bus. It can also be used to connect the output of other mixers
so you don’t use input channels.

8.6 CUE AIR (External) INPUT

The CUE Air (External input) switch allows for playback of the
outputs from stereo devices such as CD players, tape machines,
computer sound cards, iPods, or the OFF-AIR signal to be routed to
the CRM (monitor buss). Its sensitivity is -10dBv (300mV). Note:
The Cue sys-tem (from anywhere in the mixer) will interrupt the
EXT signal when activated. The CUE Air output is internally routed
to the USB-4 channel. So a final broadcast processor could be
inserted in between the main Pro-gram output and the CUE Air
input that in turn is routed to USB-4.

23

8.7 ANNOUNCER

The AIRLITE has a separate Announcer stereo jack output that
normally follows the Program left and right signals, but in case a
guest wants to hear a caller the Auto Cue needs to be activated to
fol­low the Cue selection in the console to listen tot the CUE system.

8.8 AUX CUE

The AUX SEND CUE switch allows for the master LED bar meters to
display the Aux output signal of the Aux master as well as listening
to the signal from the AUX buss. It is necessary to turn the AUX
SEND master control up to be able to create and show an outgoing
AUX signal.

8.9 PHONES

The phones output (located on the front panel) automatically
switch-es between Main Program outputs and CUE from any input
module or from the Master section. Normally the left/right output
is heard until a Cue switch is activated from anywhere in the
console. By pressing a CUE switch, you will hear the associated
signal rather than the left/ right signal in the PHONES. The led bar
and software meter applica-tion switches accordingly with this
action.
We advise you to use headphones with an input impedance NO
LOWER THAN 32 Ohms to avoid mismatch or distortion. An 8-32
Ohm set of headphones will produce distortion when cranking up
the level of the AIRLITE to high due to the fact that the impedance
load is too low. If you must use 8-32 ohm phones, a small power
amp should be used to power the phones. It is a load equivalent to
the load that loudspeakers normally present to power amps. The
AIRLITE has no power-amp built in, sorry.

8.10 CUE RESET

The Cue reset button alongside of the Phones volume control resets
all active Cue selections in one go. So you do not have to switch
them off individually.

8.11 CRM SECTION (Control Room Monitor)

The CRM control is normally fed by the master outputs. In case a
CUE switch is activated the CRM output switches automatically to
the selected CUE signal. In case you do not want the CRM output
to be switched automatically to CUE disengage this function by de­activat-ing the Auto Cue. The CRM signal can also be used for an
extra stereo output for recording or a sound system.

8.12 TALKBACK TO

The Talk back circuit has a built in electret microphone with
routing to three outputs. By selecting one or more of the routing
switches, you can communicate to the outputs VoIP, Announcer and
or AUX. The Talk back level is independent of settings of the master
controls and Announcer outputs. The Talk back switch has a
momentary action to avoid being in the talk back mode when not
wanted. If an announcer who wants to talk to the caller and is not
sitting in front of the mix-ing consoles, he can use his Presenters Mic,
the engineer activates both the Announcers mic channel’s CUE and

the caller’s CUE and now both can talk with each other. The Talkback

level can be adjusted by the TB level control just below the NON­STOP switch.

24

8.13 METERING

Part of the total AIRLITE package is a software meter application and clock as seen above.
All data are transported over the single USB 2.0 connection. An accurate clock time is taken from the local PC.
The left stereo meter always shows the Master output, the right stereo meter shows the CRM output level following
every signal selected by the CUE switches.
On the right hand side of the display you see signalling functions of some important functions in this mixer.
When the ON-AIR 1 or 2 sign is activated. The NON-STOP switch is active when a Silence is detected in the program signal, a

Mic is on(active) or the the CRM is muted.

On the bottom of this display you can monitor the status of all the input channels whether they are active, off or standby
and also the source selected.

25

9 MASTER BACKPANEL CONNECTORS

The master connector panel houses 12 RCA/Cinch connectors, 2 jack sockets, and 3 male XLR connectors and 2x USB
connectors. There is one power supply connectors. From left to right -we will describe the functions and features of the master
connector panel as seen below in detail.

9.1 POWER CONNECTOR

This 5 pin XLR connectors accepts an external 12 volt 5A switched low energy power supply that is part of the delivery.
DO NOT USE ANY OTHER POWER SUPPLY THEN THIS ONE!!!
Your AIRLITE can accept voltages between 90 and 230 volts at 50/60Hz.

9.2 AIR INPUTS

These inputs are for instance intended to return stereo ON-AIR signals in the monitor section for checking live ON-AIR signals.
The input level should be at least -10dBV.

26

9.3 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). You can connect the inputs of reverbs from these outputs (with Aux send jumpered to post
fader) or use them as a monitor out-put, after you jumper the Aux send in the channels to pre fader.

9.4 CRM SEND

The CRM (Control Room Monitor) outputs are on two RCA Cinch connectors carrying the signal coming from the CRM
volume potentiometer on the front panel and its associated source selection. The level is +6 dBu (1.55 volt).

You can connect the inputs of Active monitors to Cinch connectors.

9.5 CUE (SEND)

The CUE outputs are on two RCA Cinch connectors with the signal coming from the CUE mix busses. If you want a separate
CUE loudspeaker, use these 2 outputs. The level is +0 dBu (0.775 volt).

9.6 AUX RETURN

The Aux return connectors are controlled by the Aux return control on the master section. The signal is connected directly to the
master main mix busses. You can connect reverb returns or other stereo signals without using any input modules. The input level
should be at least -10dBV.

9.7 MASTER (SEND)

The PROG (Program) outputs are on two RCA Cinch connectors carrying the same signal as is on the Master left right XLR’s

and this is also the case when the NON STOP ON-AIR switch is activated. Then the main XLR outputs carry the USB-1 signal.
This non switched output can be used for recording when the console is in its NON STOP mode. The Prog output connectors are
left and right outputs for connecting the inputs of a stereo audio recorder or any other analog or digital device. Output level is

-10dBv (-7.8dBu / 300mV).

27

9.8 MIC ON

Directly beneath the CUE cinch connectors is a stereo jack socket (Mic On) that can control a red light indicator. This stereo jack
is connected to an OPto coupler. This Optocoupler capable of controlling external Red light circuits as long as it doesn’t take a

higher voltage than 24 volt and the current doesn’t exceed 50 mA! Individual channels can be software jumpered off from this

buss. NEVER CONNECT 115/230 AC VOLTAGE TO THIS JACK!!
The Optocoupler is connected to the Tip of the stereo jack.
The Optocoupler is also connected to the ring of the jack.
The “sleeve or ground” of the jack is not connected to anything.

9.9 ANOUNCER PHONES JACK

The Announcer /PHONES output is 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 a CUE switch is activated, then the announcer can be linked to Cue signals for communication with DJ’s and or
Callers. The level is dependent upon the Announcer master volume control and is able to drive 400 Ohm headphones as a
minimum impedance. If more headphones need to be connected a separate headphone amp is a solution.

9.10 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).

9.11 MASTER AES/EBU XLR CONNECTORS

The master AES/EBU XLR is an optional digital output that can be ordered if you want to go fully digital to the transmitter or
other broadcast devices connected to the AIRLITE. The AES/EBU connector will always be mounted, even if the digital card is
not installed inside your mixer. So do not be surprised if the output is not working if you have not purchased /installed the
digital option.

Our D&R ON-AIR warning light can be connected directly to the MIC-ON jack socket
be-tween tip and ring by way of a simple 2 wire connection.
The ON-AIR led light has its own external power adapter.

28

10 SET-UP ROUTINES MODULE 1-3

• Connect a power-amp, recorder, or transmitter to the Master left/right main outputs.

• Connect a high impedance (NOT BELOW 32 Ohm) headphone to the “phones” jack socket on the

master section.

• Connect a microphone or line level equipment.

• Now, connect turntables (with built in RIAA pre-amps), CD players, and jingle machines.

• Connect a red light indicator to the master section when there is a need for it.

• The Announcer output can feed high impedance (400 ohms and above) stereo headphones directly.

• Now with everything connected, follow the adjustment procedure.

• Note; for mikes, only activate the grey Mic switch, for line level, leave this switch up.

• Put on your headphones and turn the headphone volume control to the “12 o’clock” position.

• Set all the gain-controls and the master faders to its minimum.

• Set all equalizer-controls to the “12 o’clock” position.

• Connect your external power supply and connect this supply to the mains voltage, the first LED in

the LEDbars should be on.

10.1 SETTING UP AN INPUT CHANNEL

Push the CUE switch in a channel that is connected to a source. Now slowly turn the GAIN control
clockwise until you hear and see the input signal on the LED bars in the master section. You can change
the input sound by adjusting the equalizer-section.
If you adjust the equalization, once again check the level on the led bar, because increasing specific
parts of the frequency spectrum can easily add more gain to the signal.

The LEDbar indication should be between -6 dB and +3 dB to get a proper level on amplifiers or your
main out processor. The LEDbar is a PPM meter indicating the absolute level that enters the console. It
is calibrated to indicate 0 dB on the scale corresponding with a +6 dBu output level. Release the CUE
switch so the led bar can now read the output signal again. Now push the ON button to connect the
input signal to the fader.

Now move the fader to the “10” position screened alongside the channel faders or to the 0dB indicator

if you have cancelled the extra 10dB fader gain in the software. Further volume adjustments can be
made on the equipment your signal is send to, such as power-amps or transmitters. The other inputs
are similarly adjusted, using the “CUE” switches to (pre fade) listen to the connected sources. Use the
input gain for regular gain adjustments to create a convenient gain range to work with. Be carefully not
to place the AIRLITE near heavy power transformers such as power amps. Although the AIRLITE is
constructed using a thick metal frame, this could cause hum.

SETTING UP THE USB MODULES

Input modules 4 to 7 are also capable of accepting stereo USB
signals from a PC where you have play-out software running. To be
able to set up a connection with your PC, use a standard USB cable
from a local computer shop. (See picture). When connecting the
AIRLITE to your computer, the computer (PC or Mac) will recognize
the AIRLITE as new hardware and will establish a connection to any
audio programs needing audio hardware. Also all 4 stereo channels
will be automatically put in a natural sequence of 1 to 4. After
establishing a connection, there is no need to down-load drivers or
performing complicated setup routines, just plug in the USB cable
to your Windows or Mac computer and start tracking/playing! If you
first want to know more about USB try this link

29

11 SET-UP ROUTINES MODULE 8 (VoIP)

Connect an extra USB cable just like the one you used for the Play-out system and connect it from the
USB VOIP connector to an extra USB conenctor on your PC or to another PC.
Install for instance SKYPE on you PC and set up an account according to the instructions of the

SKYPE software.
Once the dialed person has taken the call or you have answered the call,
inside the SKYPE application you can talk to him via the internal Talk back
Microphone or make a connection outside the broadcast by first pushing
the Conn switch and then pushing both the CUE switch of your DJ channel
and the VoIP channel.
If you want some else to talk to him or her also prior to the broadcast
push any CUE button and communication is established.

As a start position both VoIP send and gain potentiometers in the 12
o’clock positions. And adjust when needed.

An incoming call is picked up by pushing the CONN button.
If you want to hear the caller, press in the same channel the CUE button
to listen to the incoming call.
Adjust the Gain control to get a good input level from the telephone line.
To be able to talk to the caller press the TB (Talkback) VoIP in the far

right section of the master and… talk to him or use another MIC input of

the mixer and push the CUE there too. Adjust the VoIP send
potentiometer to increase or decrease the outgoing level to the caller.
Note: This is all happening outside the broadcast.
If all is OK and both parties know what to do, you can press the ON switch
and fade up the caller ON-AIR, or, put the fader in its “0 or 10” position and
activate the ON switch to put the caller on-air.

If you do not have access to the internet and want to establish a classic connection over the phone com­panies connect a telephone Hybrid between the Cleanfeed send co inch sockets and the stereo line cinch
inputs of the VoIP channel. Both stereo line input cinch sockets need to be feeded with the same signal.
Both cleanfeed cinch sockets carry the same mono signal, which is also send to USB channel 5.

13.1 Introduction

Airlite Configuration Manager is a software tool to configure the Airlite console. This manual describes the
features Airlite Configuration Manager contains and how to setup and use the application.

13.2 Connection & Setup

Airlite Configuration Manager communicates indirectly with the Airlite console over an Ethernet connection using
UDP/IP (User Datagram Protocol). Since the only available physical communication interface on the Airlite console
is USB, another Airlite Control application is required to run on the PC the Airlite is connected to (main PC).The
Airlite Control act as a USB/UDP gateway and provides a communication interface for client applications anywhere
on the network, like Airlite Configuration Manager.

In order to use Airlite Configuration Manager follow the steps below:

1. Connect the USB-main port of the Airlite to your PC with supplied USB cable

2. Install, configure and run the Airlite Control application on this ‘main’ PC

3. Run Airlite Configuration Manager on any PC in the network, or from your home!

34

13.3 Communication

Pressing Options->Communication from the menu bar will open the communication settings window.

13.3.1 Remote Host

In the Remote Host field the IP address of the main PC needs to be specified. For running the Airlite Configuration
Manager on the main PC one can use the 127.0.0.1 (localhost) IP address.

13.3.2 Ports

Airlite Configuration Manager uses a transmit- and receive port for the communication to/from the Airlite console.
By default these ports are pre-configured and do not need to be changed unless specific port configuration is
required.

35

13.4 Module Settings

In this chapter the module settings for the eight modules present in the console are discussed. Each module has
its own settings tab.

Apply a configuration section of the selected module to all other modules.

Apply entire configuration of the selected module to all other modules

13.4.1 Power ON Active

The Airlite console contains ON-switches to activate a specific module.
If ON Active in the Power section is enabled the module will be active when powering the console. Using this

function while a power outage occurs prevents silence on air if no person is in the studio to (re-)activate the
module.

36

13.4.2 Auto CUE Reset

When the CUE-switch of a module on the console is activated (also called PFL) the selected source (LINE or
MIC/USB/VoIP) will be routed to the CUE buss. To deactivate a module from the CUE buss one can press again
the CUE-switch.

The Auto CUE Reset feature can reset the CUE buss (deactivate all modules from the CUE buss) automatically
by Fader, ON and/or Fader+ON. The function can be enabled for LINE and MIC/USB/VoIP separately.

13.4.3 Fader Dynamics

The fader top level can be set to +10dB instead of the normal 0dB level with this setting enabled. This results in
10dB more headroom which could be desirable in certain circumstances.

13.4.4 On Air Busses

Two logical on-air busses are available which can be enabled for LINE and/or MIC/USB/VoIP for each module.

13.4.5 Switch Colors

In the Switch Colors section the colors of the ON- and CUE switches can be configured to be OFF, RED, or
GREEN depending on the state of the switch-function. It is up to the user to define a suitable color for a
corresponding state.

ON states:

• ON Active

• ON and Fader Active

• ON Inactive

CUE states:

• CUE Active

• CUE Inactive

13.4.6 CRM Feedback Prevention

** These settings are only available for modules 1,2 and 3 (MIC modules) **

In order to prevent feedback from a microphone in the Control Room the functions CRM Mute and CRM Auto Cue
– (AutoDeactivate) can be enabled.

CRM Mute:

➢ Mute CRM buss when the module is active (MIC selected).

CRM Auto Cue – (AutoDeactivate)

➢ Deactivate the Auto Cue CRM function when cue’ing module (MIC selected).

37

13.4.7 Studio Remote

** These settings are only available for modules 1,2 and 3 (MIC modules) **

With a studio remote connected to the GPI connector at the back of the console one is able to perform Cough and
Comm (Communicate) functionality.

Cough:

➢ if enabled the module is muted when the cough button on the studio remote is pressed

Comm:

➢ if enabled the module is deactivated and put on the CUE buss when the comm button on the studio

remote is pressed.

Comm Private:

➢ if enabled the module is deactivated and put IF ONLY on the CUE buss when the comm button on the

studio remote is pressed. (Comm must be enabled).

13.4.8 Microphone

** These settings are only available for modules 1,2 and 3 (MIC modules) **

Phantom enables +48V power on the MIC XLR-connector required for condenser microphones.
MIC at Line – set this option if a microphone is connected at the line input (using external preamp).

38

13.5 Master Settings

In this chapter the master settings of the console will be discussed.

13.5.1 Silence Detection

The Airlite console is equipped with a software silence detection unit and is used to monitor the program buss (left,
right or stereo) in the event of the signal going below the threshold (-40...0dB) after a given interval. In this
situation the unit will go into ALARM state and switches the nonstop source to the master output. The Interval Unit
can be set to seconds or minutes.

The red flashing nonstop switch on the console indicates the alarm state. The silence alarm can be reset by
pressing the nonstop switch (will become green). Program buss is routed to the master output after the reset.

39

13.5.2 GPO

The Airlite console contains two GPO’s (General Purpose Output). These GPO’s can be triggered by different events.

In some cases the output needs to be inverted to obtain the correct result depending on the connected target (On­Air lamp e.g). The Inverted Output inverts the output of the GPO easily where otherwise a relay is needed.

GPO Triggers:

• On Air 1

• On Air 2

• Phone

• Mic On

• Non Stop

• Module 1..8 Active

The GPO’s can be configured in continuous or pulse mode. Pulse mode can be used to trigger a cd -player when a
module becomes active (faderstart). Pulse can be generated by ON, OFF, or ON/OFF state of the selected trigger.
Pulse-width can be configured from 10 – 255 milliseconds.

13.5.3 Switch Colors

In the Switch Colors section the colors of the CUE switches for the Aux, Air, and NonStop can be configured to be
OFF, RED, or GREEN depending on the state of the switch-function. It is up to the user to define a suitable color
for a corresponding state.

CUE states:

• CUE Active

• CUE Inactive

13.5.4 Cue Buss Interlock

If enabled only one module can be active on the CUE buss. Selecting a second module on the CUE buss will
result in switching to this module. Pre listen to several modules can be done in a fast way with this feature.

13.6 Read/Write Configuration from/to console

To read the configuration from the console into the Airlite Configuration Manager one needs to press the ‘READ’
button. The Firmware field shows the current firmware in the console after the read command. Once the
configuration is read successfully, adjustments can be made and written back to the console or saved as a preset.

Pressing the ‘WRITE’ button uploads the current configuration in Airlite Configuration Manager to the console. The
configuration is directly active but not saved internally. The configuration is lost after a power off.

13.6.1 Store Internal

The Store Internal button stores the current configuration in the console to persistent memory (EEPROM). This
means the configuration is still active after a power off. A warning will be prompted to make sure you want to
overwrite internal saved configuration.

13.7 Configuration Presets

Airlite Configuration Manager is able to import/export the configuration from/to a preset file. These preset files
have the .xml file extension. A preset file includes the module and master settings.

13.7.1 Create Preset

Saving a preset can be done by pressing File->Save(as) from the menu bar.

13.7.2 Load Preset

Loading a preset can be done by pressing File->Open from the menu bar and selecting the preset file.

14.1 Introduction

Airlite Meters is a software tool to let you as user monitor and control the Airlite console in an intuitive and user
friendly manner. This manual describes the features Airlite Meters contains and how to setup and use the
application.

14.2 Software elements

14.2.1 Analog and Digital clock

Airlite meters provides an analog as well as a digital clock which display PC system time the application is running
on. The analog clock contains a seconds dot counter which can be used as indicator for program end time
countdown.

14.2.2 PPM meters

Two stereo PPM(Peak-Program-Meters) meters provide real-time and accurate readings of the Master- and
CRM(Control Room Monitor) buss audio levels. A variety of PPM meter scales exist these days with all different
range and read out. Based on the most used scale the following type is used: IEC 60268-10 Type I, DIN scale.
This scale ranges from -50 till +5dB.

14.2.3 Silence detection

Since continuous radio is important for a radio station, the Airlite is equipped with a built-in software silence
detector which guards presence of audio signal on the master output. If no sound is present for a specified time,
the console generates an alarm and switches automatically to non-stop mode.

When the silence detector is active red line marks in the master PPM bars indicate the threshold as well as the
operating mode which can be left, right or stereo.

14.2.4 MIC ON Timer

The first three modules of the Airlite can be used for connecting microphones. If one of these mic modules is active
(source selector is set to mic, ON is active and fader is up) the MIC ON timer will start. Once the timer is active the
elapsed time is shown in the analog clock area below the system date. The timer will reset if all the mic modules
are inactive.

43

14.2.5 Settings

Pressing the gear wheel symbol at the right upper corner will open the (communication) settings window.
Airlite Meters communicates indirectly with the console via a UDP/IP (User Datagram Protocol) connection. Since

the only available communication interface on the Airlite console is USB, another Airlite Control application is
required to run on the PC the Airlite is connected to. The Airlite Control act as a USB/UDP gateway and provides a
communication interface for client applications anywhere on the network, like Airlite Meters.

14.2.6 Online indicator

Below the D&R logo the online indicator is located. This indicator will become green (online) when receiving
metering data. Make sure the Airlite Control application is running on the main PC in order to provide the metering
data to Airlite Meters.

When the indicator shows offline status (grey) the Airlite Control application is not running or the Airlite console is
disconnected.

44

14.2.7 Console signals

At the right side Airlite Meters contains a set of console signals indicating internal states of the console.
PHONE: Will inform you with an incoming call on module 8 (VoIP).
ON AIR 1/2: Configurable Logical busses. Can be attached to a GPO for example.
NONSTOP: can be used as indicator as well as remote nonstop switch by clicking on the signal.

SILENCE: Indicates the silence detector is in alarm state. In this alarm state NONSTOP is flashing to indicate

the console has switched automatically to nonstop mode. The alarm can be reset by clicking on

NONSTOP or by pressing the nonstop switch on the console.
MIC ON: One of the mic modules is active. Behaves parallel to the hardware MIC ON output.
CRM MUTE: CRM buss is muted by active mic module where crm-mute option is enabled.

14.2.8 Module states

The Airlite console contains eight modules in which their current state is represented by the rectangular icons at
the bottom of the application. Each icon show the state of the ON switch and the selected source of the relevant
module.

14.2.9 ON-switch

A module can be in one of the following three states:

ACTIVE: ON active, fader down
ACTIVE_AND_FADER_ON: ON active, fader up
INACTIVE: ON inactive, fader down

Since the ON switches of the Airlite console have internal LEDs, each of the above states can be configured to
represent one of the following colors: NONE, RED, GREEN. It is up to the user to determine which color represent
a particular state.

The icons in Airlite Meters can be seen as duplicate of the ON switches and therefore behave as remote of the
hardware switches. Clicking on the icons results in toggling the ON state.

*** NOTE: If the icon flashes, the module is in voicetrack-mode.

14.2.10 Source select

Each module can select between LINE and MIC/USB/VoIP source depending on the module. Additional to
showing the ON switch state, the current selected source for each module will be shown in the right down corner of
the icons.

45

14.3 Setup

In order to use Airlite Meters follow the steps below:

4. Connect the USB-main port of the Airlite to your PC with supplied USB cable

5. Install, configure and run the Airlite Control application on this ‘main’ PC

6. Run Airlite Meters on any PC in the network, or from your home!
