1 INTRODUCTION
The DN3816 matrix is a low-level switching matrix which uses EtherSound technology ; by using
bidirectionnal transmission of 64 digital channels (24bits coding, sampling 48Khz), this technology gives
possibility to build audio matrix on a dedicated 100 Mb/s LAN network.
Because this technology is totally compliant with Ethernet 802.3x requirements, all compliant components
(switches, Cat5 cable, optic fiber, …) can be used to build the EtherSound network (layer 2 level).
Internal processing and signal processing are fully digital, using SHARC© Digital Signal Processing (DSP)
technology. DSP technology provides the DN 3816 matrix with a wide range of audio signal processing
options and at the same time allows extremely flexible configuration. This product is designed for using in
applications where several high quality audio sources need to be selected and broadcasted to several audio
outputs.
2 GENERAL TECHNICAL SPECIFICATIONS
The matrix has the following features:
• 8 audio analogue inputs
• 16 audio analogue outputs
• 8 logic inputs
• 16 logic outputs
• 1 x RS232 interface for use by configuration application “Matrix Control”
• 1 x dual RS485 interface for bus console management (GX3016, GXT4000, …)
• 1 x RS232 interface for communication with external equipment.
• 1 x EtherSound interface
The following digital audio processes can be applied to each audio input :
• level adjustment
• bass/treble
• adjustable noise gate
• mute
The following digital audio processes can be applied to each audio output:
• level adjustment
• 5 band parametric equaliser
• mute
• delay (up to 5s for each output)
3 GENERAL DESCRIPTION
The DN 3816 is a programmable digital audio routing matrix with a wide range of features and applications.
Basically, the DN 3816 can be used to switch 8 audio input channels to 16 audio output channels. Switching
may be triggered in a number of ways including according to audio input priority levels. The DN 3816 also
offers audio signal processing such as sound detection, noise gate, tone adjustment and a 5 band
parametric equaliser.
Two console buses (GX 3016, GXT 4000, …) can be connected to a single DN 3816 for broadcasting
spoken announcements to one or more audio output channels. In addition, the matrix has 8 general purpose
logic inputs (logic GPIs) and 16 general purpose logic outputs (logic GPOs). The logic GPIs provide dynamic
switching control of the 8 audio input channels to the 16 audio output channels. The logic GPOs are used to
provide information on the status of the matrix to other system equipment.
The matrix will run off either 230V AC. or off 24V DC using a suitable transformer.

4 APPLICATIONS
4.1 Public-Address Matrix
Basically equipped with 8 inputs and 16 outputs, the DN3816 is designed to build all size audio
switching matrix of which exploitation is managed by an application server (consult Bouyer for details
explanations).
Due to the design, the DN3816 has a mixed operating mode ; that means that some actions can be
dedicated to the DN 3816 (by preliminary settings) without intervention of the server application ; in this
case, the server application is notified by the DN 3816 when actions are achieved ; this is possible, for
example, when a source switching is always operated on one or several zones of the same matrix and
when the triggering of this action is managed by the matrix (local console, local remote, …).
Design example : 24 inputs and 48 outputs audio matrix

7.5 Connecting GX 3016 consoles and an RS232 serial control device
Preamble : the following explanation made for GX 3016 console is also available for all other bus console types (GXT
4000, …) from Bouyer.
The GX 3016 microphone console is a PA console with zone selection. It handles general PA broadcasting plus
broadcasts in up to 16 different zones. It is designed to operate using an RS485 bus architecture, meaning that
several consoles can be used on the same installation.
Up to two GX 3016 console buses can be connected to the DN 3816. All the consoles on the same RS485 bus
occupy just one audio channel. The consoles determine automatically which gets to use (occupy) the single audio
channel.
Bus 1 of the DN 3816 uses audio input 5 and bus 2 uses audio input 6.
Up to thirty-two GX 3016 consoles can be connected to a single DN 3816 matrix. The RS485 serial link allows the
consoles to be chained together up to a total maximum length of 1200 m without use of a repeater. The GX 3016
consoles should be connected to either bus 1 or bus 2 depending on the type of application being implemented. For
more information on installing and cabling the GX 3016 consoles, refer to the GX 3016 User Manual.
stream
10
The GX 3016 consoles connected to bus 1 must be set to address 1 and the consoles connected to bus 2 to address
2 (see figure above). To set the addresses on the GX 3016 consoles, refer to the GX 3016 User Manual. Use the
RJ45 cable to connect up the GX 3016 consoles (refer to the wiring details below).

RJ45 wiring details for the GX 3016:
Warning
The DN 3816 can power up to eight GX 3016 consoles via the RJ45. If the installation consists of more
than eight consoles, then an external power supply should be added, to be connected to the Jack socket
on the consoles.
Using GX 3016 consoles on bus 1 and/or 2 means that audio inputs 5 and/or 6 cannot be connected to
any other sources, otherwise the system will not work correctly.

7.9.1 Using GPOs
To drive a relay type load using a GPO, the load needs to be connected between the output terminal and the
+24 V common on the GPO connector block.
7.10 Starting up the DN 3816
Use the ON/OFF switch on the mains block on the rear panel to switch on the matrix unit.
The green ON indicator will light to show the unit is powered up.
Once the unit has initialised (which takes less then a second), the matrix will briefly display its software version
number using the green audio input and output SIGNAL diodes. The version number is displayed in the form x.y,
where x corresponds to the audio input number that lights up, and y the audio output number that lights up.
WARNING: The DN 3816 matrix supplies +24 V d.c. to power loads connected to the
GPOs. The current is limited to 0.56 A. If a higher current load is required for the GPOs,
then an additional external +24 V d.c. power supply should be used.
+ : +24 V common

After the version number is displayed, the list of audio inputs and outputs in service on the matrix is displayed
(corresponding leds are ‘On’) during 1s. During the display of the version and of the list of inputs and outputs in
service, the green STATUS led is ‘Off’.After displaying the list inputs and outputs in service, the green STATUS
indicator comes ‘On’ permanently, at which point the matrix is fully operational.
8 CONFIGURING THE DN 3816
Configuring the DN 3816 is a 2 stage process that consists of configuring the hardware and configuring the software.
Hardware configuration involves setting the physical characteristics of each of the audio inputs where possible
(microphone or line input level, use of phantom power).
Software configuration is split into 2 parts: defining the unit’s operation and setting the digital process parameters. The
software is configured using the « Matrix Control » application supplied. To install and use this program, refer to the
software user manual (the CC3816.chm html Help file supplied with the software installation package).
This section explains the various different steps to follow to direct an input signal to one or more outputsThere are several
steps which should be followed to configure the matrix :
WARNING : If during initialization, the number of inputs (normally 8) and outputs (normally 16)
isn't correctly displayed, and if output 'Signal' leds are blinking permanently, that means that the
DN3816 product is locked. In this case, the DN3816 product has to be unlocked ; this operation
is achieved by using the Matrix Control software and need to enter an unlocking code that has
to be delivered by Bouyer on demand.

8.1 Hardware configuration: setting the physical parameters of the audio inputs
WARNING: These configuration instructions are for the attention of qualified personnel
only. To reduce the risk of electric shock, do not undertake any operations other than
those provided here. Switch off the DN 3816 and disconnect the power lead before
carrying out any work.
The DN 3816 matrix input type on audio inputs IN 1 to IN 4 can be changed. This can be done using the configuration
jumpers located on the interface board situated inside the matrix along the back plane.
The location of the various configuration jumpers on the interface board :
13
DN3816
Page 14
There are two possible configurations for inputs IN 1 to IN 4: Line input (0 dBm) or Micro input (-52 dBm). In addition,
when audio inputs 1 and 2 are set to Micro, these can be supplied a phantom power supply for powering electret
microphones. Whichever configuration is to be used, follow the procedure below to set the inputs according to the
desired application.
To change the audio input type (IN 1, IN 2, IN 3 and IN 4), place the relevant jumper on the corresponding MIC or
LINE pins as required. To enable a phantom supply (SUPPLY 1 and SUPPLY 2) on the corresponding inputs IN 1 or
IN 2, fit the corresponding SUPPLY jumper:
First ensure that the DN 3816 is switched off and that the power cable is unplugged before opening up the
unit.
To avoid electrostatic discharges, first ground yourself using an earthing lead before opening up the DN
3816.
Open the cover by undoing the two screws on the rear panel.
Locate the jumpers on the interface board located on the unit’s rear plane and place them in the required
positions.

8.2 Software configuration
8.2.1 Functional definition
This section covers all the parameters that need to be set to determine how the matrix should work.
8.2.1.1 Setting the audio input source parameters
These parameters can be set under the «
An audio input signal can be directed (switched) to one of the audio output channels if the audio input
channel has been activated. An audio input channel may be activated by several trigger signals which
depend directly on the parameter set under the «

DN3816
Page 15
The concept of Speech and Music audio types exists so that, regardless of any priority levels set
elsewhere, a « Speech » audio channel is always given priority over a « Music » audio channel.
8.2.1.1.1 Modulation detection
8.2.1.1.2 DAS channel 1 and channel 2
8.2.1.1.3 Persistent
The modulation detection feature activates the option within the DN 3816 to detect a signal
level. An input channel will be activated when the input signal level exceeds a preset trigger
threshold. If the signal exceeds the trigger threshold on the input channel, it may then be
directed to one of the output channels.
This type of source could, for example, be used to provide automatic noise level detection of
a signal from such as a microphone. The input to which this microphone is connected will
then be directed to an output if the signal level on this input exceeds the preset threshold.
Accidental activation will be impossible so long as the input signal remains below this
threshold.
Switching will then be deactivated once the input signal level drops below the predefined
threshold.
The DAS feature allows an input channel to be selected and activated over the DN 3816’s
serial data link (for Digital Automatic System).
The Persistent function is used to permanently activate an input channel. This feature
should be used if an input signal needs to be available all the time for switching to one of the
outputs. This configuration is especially useful in background (piped) music applications
when combined with a CD player or satellite receiver.
8.2.1.1.4 GPI remote control
An input channel may be selected using a dry contact type logic GPI. A switch may be
connected to one of the GPIs in order to switch an input channel to one of the audio outputs.
8.2.1.1.5 GX 3016
This source type is reserved exclusively for the DN 3816 matrix’s audio inputs 5 and 6. Input
channel 5 must be set to type GX 3016 if a set of GX 3016 consoles is to be connected to
bus 1 of the switch matrix. Similarly, input channel 6 must be set to type GX 3016 if a set of
GX 3016 consoles is to be connected to bus 2 of the matrix.
8.2.1.1.6 Modulation Detection parameters
The three parameters associated with this feature are Detection Threshold, Detection Time
and Release Time, all of which are accessible under the «
8.2.1.1.6.1 Detection threshold
8.2.1.1.6.2 Detection time
Sources Types
This detection threshold is the level above which a Sound Detection-configured
input channel is allowed to activate.
This threshold is adjustable from -50 to 0 dBm.
This is the time duration from the moment the signal goes over the threshold to
the moment the input channel is activated.
This time is adjustable from 10 to 100 ms.
» tab.
8.2.1.1.6.3 Release time
This is the time duration from the moment the signal drops below the threshold to
the moment the input channel is deactivated. This option prevents the channel
from being deactivated unnecessarily during pauses between music tracks when
an input is configured to use Modulation Detection and an audio CD is being
played over that channel.
This time is adjustable from 10 to 10,000 ms.
8.2.1.2 Prioritising audio inputs according to audio outputs
These parameters can be set under the «
15
Priorities
» tab.
DN3816
Page 16
A powerful priority level management algorithm is used to control the switching of the audio inputs to the
outputs. Each audio input is assigned a priority level (from 0 to 15) which can be adjusted according to the
audio output used. Level 1 is the highest priority level and 15 the lowest. Level 0 indicates that the audio
input cannot access that particular audio output. Thus if two audio input channels are active at the same
time on the same audio output, then the one with the highest priority will be switched to the corresponding
audio output. Where both inputs have the same priority value, priority is assigned to the one that requested
the output channel first.
In addition, regardless of the priority levels, a « Speech » audio channel always gets priority over a
« Music » audio channel.
8.2.1.3 Setting the Group parameters
These parameters can be set under the «
The DN 3816 includes the option of programming groups of outputs so that, for example, an audio input
can be directed to a group of audio outputs. In applications involving sound and PA systems in public
places, different groups of outputs may correspond to different geographical zones, where each zone has
its own particular set of loudspeakers.
With the DN 3816 switching matrix, up to 16 groups of 1 to 16 outputs can be programmed.
8.2.1.4 Setting the GX 3016 console key parameters
These parameters can be accessed under the «
These tabs relate to the GX 3016 address 1 consoles (bus 1) and the GX 3016 address 2 consoles (bus 2)
respectively. The programming of each of the keys (Zone Selection, Group Selection) of the consoles is
valid for all the GX3016 console connected on this same bus.
Thus, each key on the GX 3016 address 1 console may be configured with an audio output to switch the
audio input 5 (that of the GX 3016 1) to the chosen audio output. Similarly, each key on the GX 3016
address 2 console may be configured with an audio output to switch the audio input 6 (that of the GX 3016
2) to the chosen audio output.
In addition, each key on the GX 3016 address 1 console may be configured with a group of audio outputs
to switch the audio input 5 (that of the GX 3016 1) to the audio outputs of the chosen group. And similarly,
each key on the GX 3016 address 2 console may be configured with a group of audio outputs to switch the
audio input 6 (that of the GX 3016 2) to the audio outputs of the chosen group.
For more information on operating GX 3016 consoles, refer to the GX 3016 User Manual.
8.2.1.5 Setting the GPI parameters
These parameters can be set under the «

8.2.2.1.1 Using Noise Gate on audio inputs
8.2.2.1.2 Setting Bass/Treble on audio inputs
A GPO configured with the function
one of the inputs selected is switched to the chosen audio output.
Each of the DN 3816’s inputs incorporates a digital noise gate which may be very useful for
eliminating earth hum, interference and other system background noises which may
randomly occur. The noise gate feature uses a powerful dynamic processor that works like
an automatic gate that lets through only the useful part of the signal. In fact, the noise
gate function only lets the signal through if it exceeds a predefined level. It thus separates
out the signal’s useful component from any background noise that may be present on the
input.
The noise gate threshold can be adjusted from –90 to 0 dBm.
A standard Baxendall tone control circuit is incorporated on each of the DN 3816’s inputs for
digitally adjusting bass and treble. The mid-range frequency for adjusting the bass is 100 Hz
while the midrange frequency for adjusting the treble is 10 kHz.
The gain for each of these two frequencies is adjustable from -18 to +18 dB.

8.2.2.1.3 Setting Mute on the audio inputs
Each input channel has its own Mute function. This is used to deactivate the input signal.
8.2.2.1.4 Adjusting Volume on the audio inputs
Once all the audio input settings have been adjusted, the general volume of each input
needs to be set. The volume may be set from between –60 and +10 dB using the input
volume potentiometer.
To get the maximum dynamic range from the signal processing processor, the input volume
should be set so that the average value of the signal is between –3 and 0 dB on the Vumeter.
8.2.2.2 Output audio adjustments
The audio settings for the outputs are available under the «
8.2.2.2.1 5 band parametric equaliser
Each of the DN 3816’s output channels incorporates its own wholly independent equaliser.
Each of the output channel’s equaliser sections can be used to make fine tone adjustments
to the signal.
The equaliser section provides true 5 band parametric equaliser functionality including
frequency adjustment Fc, quality factor Q and gain G for each band.
8.2.2.2.1.1 Frequency Fc
This is the centre frequency of the selected parametric equaliser band. The
selected frequency determines the centre frequency that may be adjusted using
Gain.
The frequency may be adjusted from 20 to 20,000 Hz.
Control
» tab.
8.2.2.2.1.2 Quality Factor Q
8.2.2.2.1.3 Gain G
17
This is the frequency bandwidth around Fc. Setting Q to a high value can be used
for example to produce a notch filter. With a notch filter, it is possible, for
example, to attenuate the Larsen audio feedback effect (the resonant frequency
sometimes produced by a microphone). A low Q value can be used to widen the
frequency bandwidth affected.
Quality factor may be set to between 0.1 and 20.
DN3816
Page 18
This determines the amount of gain or attenuation that can be applied to the
selected frequency bandwidth.
Gain may be set to anywhere from +18 to –18 dB.
8.2.2.2.1.4 N.B.: The effect of equalisation on voice sounds
Central frequency Effect on voice sounds
40 to 125 Hz Sense of power for some singers with very low voices
160 to 250 Hz Fundamentals of the voice
315 to 500 Hz Important for the quality of the voice
630 to 1000 Hz Important for the naturalness of the voice.
⇒
Too much gain on the 315 to 1000 Hz frequency range produces a ‘telephone’-type
voice.
1250 to 4000 Hz These frequencies are important for the intelligibility of the spoken word.
⇒
Too much gain in the 2 to 4 kHz frequency range can mask some phonemes; for
example, the ‘m’, ‘b’ and ‘v’ can become unintelligible.
⇒
Too much gain in the 1 to 4 kHz can result in listener fatigue.
5000 to 8000 Hz Accentuation of the voice. The 1.25 to 8 kHz range determines voice clarity
10,000 to 16,000 Hz Too much gain in this frequency range can cause sibilance (whistle in ‘s’, ‘ch’ or ‘sch’
pronunciation).
8.2.2.2.2 Setting Mute on the audio outputs
Each output channel has a Mute function associated with it that can be manually activated.
The Mute function can be used to simply deactivate – or mute – the output signal. The audio
output Mute function can also be activated by a logic GPI (cf. Setting the GPI parameters).
8.2.2.2.3 Adjusting Delay on the audio outputs
The delay function can be used to insert a delay on an audio output ; this delay can be
adjust from 0 to 5 seconds (equal to a delay from 0 to 1700 meters).
8.2.2.2.4 Adjusting Volume on the audio outputs
Once all the audio output settings have been adjusted, the general volume of each output
needs to be set. The volume may be set from between –60 and +10 dB using the output
volume potentiometer.To get the maximum dynamic range from the signal processing
processor, the output volume should be set so that the average value of the signal is
between –3 and 0 dB on the Vu-meter.
9 MONITORING THE DN 3816 SWITCH MATRIX STATUS
The various states of the matrix can be checked in real time either by directly observing the indicators on the DN 3816’s
front panel, or by using the « Matrix Control » software. The following paragraphs describe the various options available
when using the software application.
9.1 Monitoring audio levels
The audio levels can be checked by observing the green SIGNAL and red CLIP indicators on the DN 3816’s front
panel.
However, a more precise indication of audio levels is provided by the matrix configuration software. Under the
« Control » tab can be found an accurate -60 to +20 dBm digital Vu-meter for each audio input and output. In the
case of the audio inputs, the Vu-meter shows the signal level after audio signal processing. In the case of the audio
outputs, the Vu-meter shows the signal level after audio signal processing.
9.2 Verifying the DN 3816’s switch matrix routing
Routing table data is available under the « Routing » tab.
The table shows which of the DN 3816’s audio inputs are occupying each audio output. A green connection point
shows that the audio output in question is occupied by the audio input in question, i.e. that the audio input concerned
is switched to the audio output concerned.
9.3 Monitoring GPI status
GPI status data is provided under the « Routing » tab along the row labelled GPI Status. A green indicator means
that the corresponding GPI is activated.
9.4 Monitoring GPO status
GPO status data is provided under the « Routing » tab along the column labelled GPO Status. A green indicator
means that the corresponding GPO is activated.
