This section of the mixing console includes the following components: Cue speakers, VUmeters and level and configuration display with navigation keys and associated encoder.
1. Cue speakers. Allows you to hear the signals that are selected. They include an amplifier
and can be used to listen to signals in PFL mode.
2 - 3. Precision VU-meters. They have a direct, independent connection, and make it
possible to measure any digital audio signal connected to the console. They show an
average signal (VU-meter) combined with a peak meter showing withheld signal peaks.
4. LCD Display. It makes possible to view all information relating to audio signals and
configurations. In the standard mode, on its default screen, it shows the gain values (in
dB) and VU-meters for each of the input or output signals (as applicable for each
channel). Between them, there is a monitoring area for processes activation (dynamic,
equalization, filtering and test signals) and parameters changes (phase, mode and
balance); every time a process is activated or the phase, mode or balance of a signal is
modified, an indication appears in one of the 4 lines this area consists of, in the following
way:
• Line 1: it shows dynamic processes activation: “COMP” (Compressor), “NG”
(Noise Gate), “DLY” (Delay), “RVB” (Reverb) or “DYNA” (when there is more than
one active process in that channel). It also shows test signal activation: “TONE”,
“PINK” (Pink Noise) or “WHIT” (White Noise). If there are processes and a test
signal active at the same time, the indication that will be shown is the one
corresponding to the test signal.
• Line 2: it shows equalization (“EQU”) and filtering (“FIL”) activation. When both of
them are active, “EQ&F” indication appears.
• Line 3: it shows changes of signal phase (“L-R-“, “L+R-“ or “L-R+”; when it’s L+R+
no indication is shown) and mode (“MONL”, “MONR” or “ML+R”; when mode is
stereo no indication is shown). When there are changes in both parameters, “PH&M”
indication appears.
• Line 4: it shows signal balance (“BAL”) changes.
At the right, on the display, there is a PFL VU-meter with a phase correlation indicator,
making it possible to adjust the level and signal for any of the audio sources selected
(see section 3.1.7). This information changes when functions are selected for each
channel. The general routing screen is the default screen in the working mode which use
direct routing keys (“Bus Send Mode”).

2.2.1. Channel configuration in “Multiplex Mode”.
The operation of the ARENA DM configured in “Multiplex Mode” includes the same
functionalities as those found in the standard configuration, except for the following controls:
1.- Input Gain. Changes the digital gain of the signal coming into the
multiplex.
1
2.- Routing Button. This button has different functionalities depending on
the programmable key corresponding to the multiplex group is lighting or
not. If the key is lighting, the routing button will be blinking in all the
channels that belongs to that multiplex group; if the button is pressed in one
of them, it turns off and the channel is excluded from that multiplex; if you
press the button in one channel that doesn’t belong to that multiplex group
(it’s off), it starts blinking and the channel is included in that group. If the
programmable key is off, when you press the routing button of one channel,
the button turns on and the input signal is routed to its own return signal.

4.- Select Potentiometer. Adjusts the return signal gain. Pressing this
button will not launch any specific function.
5.- Select On Button. Press this button to monitor the return signal through
PFL.
6
6.- Channel Display. The display shows the return signal gain level, with
values ranging from minus infinity to 0 dB.
7.- Fader. The fader adjusts the audio level of the send toward the
multiplex.
8.- ON Button. Performs the ON/OFF function. When it is ON the input
signal is added to the multiplex, and when it is OFF, only the return is
activated.
9.- OFF Button. While this button is pressed, the return signal is attenuated
by 20 dB and the talkback microphone signal is added. Besides, any
sending to PFL is cut off. When it is unpressed, the previous level of the
return signal is recovered and the talkback microphone is cut off.
7
Programmable Keys. For multiplex operation, one button for each
multiplex group you wish to set up must be configured in the Console Setup
software. If you wish to have three simultaneous multiplexes available, you
will need to configure three programmable keys. When the key is lighted up,
all the channels belonging to the corresponding multiplex group will have
the Routing button blinking. In this status, if you press the DM PTT button,
the return signals are attenuated by 20 dB and the talkback microphone
signal is added to all the components of the multiplex in question. Besides,
any sending to PFL is cut off. If you release the PTT button, you return to
the previous situation.

Notes.
• A channel can be in one or several multiplexes, or in none.
• Several programmable keys may be pressed at the same time.
• If you press all the keys programmed with a multiplex, the Routing buttons of all the
channels that belong to some multiplex will blink.

Input Select & Set Up menu options.
3.1.2.1. Input Select.
On the display (4), open the available labels list, which has previously been
assigned to the channel by the system administrator from the console configuration
software. The format list may look like this:
The current option will be highlighted. You can scroll through the list the encoder
(6), and make your selection with OK. Any modifications made to the channel will
be applied to that input signal. The label selected (MAR4W1 in the example) will
then appear as the channel label on the display (17).
3.1.2.2. Phase L-R.
Phase of a stereo signal can be selected among four different states:
1. L+R+: L and R are in phase.
2. L-R-: both signals are inverted (180º) and in phase between themselves.
3. L+R-: R is phase inverted, so it is in opposition in relation to L that is still in
phase.
4. L-R+: L is phase inverted, so it is in opposition in relation to R that is still in
phase.
To select one of these options, you must press the middle button (5) and select the
type of phase desired using the “left” and “right” keys (5) or the rotary encoder (6).
The selection is validated by pressing the middle button or the encoder.
3.1.2.3. Mode.
Depending on the type of signal (mono or stereo), different signal routing modes
will be displayed. The selection procedure is the same as the one for the phase. If
the signal is mono, this option will not be available. If it is stereo, the mode may be
“Stereo”, “Mono L”, “Mono R” or “Mono L+R”.
In “Stereo” mode, the signal is sent to the output buses selected in the routing as
is, i.e., the L channel of the stereo input to the L channel of the stereo output, and
the R channel of the input to the R channel of the output. With “Mono L” or “Mono
R”, only the left or right part of the signal is sent equally to both parts of the stereo
output signal. Finally, with “Mono L+R”, the sum of both signals is sent to the left
and right in the output bus.

Threshold: this is the threshold above which the compressor will
act, so that input signal levels that exceed this threshold will be
affected by the compressor settings. The threshold range varies
from -42 dB to +22 dB.
Attack Time: this is the time it takes the compressor to react to an
increase in the input signal. The shorter this time, the more
sensitive the compressor will be to pulse signals, and the more
action it will take on this type of signals. With a long attack time, the
compressor will not respond as well to pulse changes in the input
signal.
Release Time: this is the maintenance time during which the
compressor keeps acting, even when the level of the input signal
has fallen below the threshold. A long release time will maintain
uniform compression, even when there are quick fluctuations in the
level of the signal. A short time will enable the compressor to adapt
more quickly to pulse fluctuations in the signal.
Compression Ratio: a compression ratio of 1:1 does not involve
any variation in the signal, as the level of the input signal is
maintained at the output. A ratio of 2:1 indicates that the level of an
input signal which exceeds the threshold will be reduced to half at
the output. The highest ratio available is 50:1, which will be used to
implement signal limiters. The limiter should reduce all signals
exceeding a certain level to that level.
Gain: this lets you apply a general gain to the signal. This means a
general increase in the level of the signal, which will especially be
noted at low input levels, under the threshold set. A general
increase in the level of the signal may generate saturation at the
output, even when the signal is being limited.
To correctly set a limiter, a threshold of between 0 and +22 dB should
be selected, with a compression ratio of 50:1 and a gain of 0 dB.

When establishing the settings, the threshold for the noise gate will be much
lower than in the case of the compressor, as its operation is the opposite. The
noise gate prevents the passage of the lower levels of the signal that could be
considered noise. Therefore, the range of settings is different.
In addition, there is an additional parameter for noise gates, which is “Hold
Time”. This is a safety period used to prevent the gate from accidentally closing
if a signal is suddenly absent, for example, in speech.

This function is available in the standard operating mode. In the “Bus Send Mode”,
the Routing control performs an activation or deactivation function on the direct
routing to an output bus that was previously associated to this button in the
configuration software; the Routing function is not available in this mode.
Using the Routing menu requires some initial data, defined in the configuration of the
system, in which the way each input is routed to the different defined outputs is
described. These outputs do not necessarily have to be physical, but more
generically are also summing buses, subgroups, masters, auxiliaries, etc.

The first column, “Av.” (Available), uses the symbol “ŽŽ“ to indicate that the
sending is available and the symbol “--“ to indicate that the sending is not
available, as it might be unavailable even when the cross point exists because
it’s been defined by the administrator.
The second column, “Destination”, is the label or name of the output to which
the signal is sent. This is assigned from the configuration software routing.
Only those destinations that were previously defined as available for that
channel will be on the Destination list. If there are more destinations than the
maximum number that can be displayed on the screen, the “More UP” or
“More DOWN” indications will appear to offer access to the rest of the list.
The third column, “Type”, shows the sending configuration and lets you
modify:
o Sending type: Str (Stereo), Mon L (Mono L), Mon R or Mon L+R.

3.1.6. Select: Access to the special functions display and controls.
Press the “Select” (12) pushbutton / indicator to associate the channel with the main
display (20) and controls (21) and (22), whose operation is discussed in Chapter 3.2
of this manual. In the special “Bus Send Mode” working mode, it will be an access
for direct routing of the signal present in each channel to the output bus associated
to this button in the configuration software. The “Select” menu is accessible in this
mode through the button that give access to “Routing” in the standard operating
mode.
3.1.7. Cue: Cue function.
Pressing the CUE button (13), will send the channel’s signal to the cue meter, that is
the PFL digital internal bus. This meter is found on the level and configuration
display (4) on the DM module. The CUE signal can also be sent to some of the
available VU meters (VU-1 or VU-2) and it will always be sent to the cue speakers
(1). Other places the cue signal can be sent to are headphones and monitoring in
control and studio room. In the special “Bus Send Mode” working mode, it will be an
access for direct routing of the signal present in each channel to the output bus
associated to this button in the configuration software; in this mode, the sending to
CUE is done by pressing the lower open-closed channel button (see section 2.2). In
the “Multiplex Mode”, this button allows you to monitor the channel input signal.
3.1.8. On Air: Signal indicator.
The “On Air” (14) indicator lights up to indicate that a signal is being sent to an
output bus. When this indicator is lit up, it means that the channel is selected, i.e.,
the red button at the end of the channel (19) is lit and the channel fader (18) is also
lifted up.
3.1.9. Select / On: Routing encoder and associated pushbutton.
The rotary “Select” control and its associated pushbutton (15 and 16) let you control
preset sends and control the balance or panorama.
By default, this control is assigned the balance or panorama function (depending on
whether the signal controlled by the channel is stereo or mono), and the associated
On switch lets you activate spatial positioning or eliminate it (if it is available from the
configuration software), thus centering sends at 50% between L and R.
The channel label display (17) shows the outputs to which the signal controlled by
the channel can be sent at any time. By default, this display will show the L - R label
with an indication of the relative position between the L bus and the R bus:
L ..........|.......... R
When the encoder (15) is pressed and turned, each of the preassigned in the
configuration software as visible outputs will be shown. Pressing again the shown
output will be selected. The encoder now can regulate the send level to this output.
Each of these sends may be activated or deactivated separately, as the user wishes,
by means of the associated ON-OFF switch (16).
In the “Multiplex Mode”, the “Select” encoder regulates the return signal level, while
pressing the “On” button launches a PFL on the return signal.

3.1.10. Opening and regulation of channels, channel label and page changes.
The ARENA DM console has channels that can be assigned to different input and
output routes in a completely flexible manner. A single physical channel on the
control surface can regulate, at different times, an input circuit signal, or an output
circuit or even a subgroup. In the configuration software the signals assignments to
each channel are defined.
In the standard mode to change pages, the active page press-button Up/Down
associated with indicator Page Swap are used (7). When changing the page, the
channel internal configuration, their light indicators and the motorized fader position
change according to the new active page.
The channel label, located on the second line of the display indicating channel
routing (17), shows the name of the input / output circuit regulating the channel at
that moment.
A fader’s (18) position can be manually modified at any time, and the last position
reached will be memorized for the active channel.
In the Memories mode you can store all the adjustments made with the controls of
the channels on the surface (except input gain, phase and mode). The storable
parameters include: signal assigned to the channel, activation and adjustments of
effects, routing status of each channel, activation status of the channel, fader
position, etc.
The channel open-closed press-buttons / indicators (19) are under each fader; their
default programming easily permits to opening or closing the channel sending to the
main master bus. In the “Bus Send Mode”, the upper pushbutton performs the
ON/OFF function, while the lower button sends the signal to the CUE bus.

3.2.1.3. Processing.
In the “Processing” option the signal can be processed in time, level or frequency. The
available effects in the “Process Menu” are:
•
Equalizer. It consists of 4 equalization parametric bands, with frequency control,
gain and Q in each one.
• Filters. It can be set up as high and low pass filters, and combining both as a band
pass filter.
• Reverb. There are 4 reverb effects: Plate, Vocal, Hall and Room. It is possible to
adjust, for each, the level, high frequency damping and decay time Equalizer.
• Delay. Allows you to apply brief delays whose primary purpose is to make a
temporary adjustment among several signals. There are two delay ranges (Short
and Long) that enable adjustments of up to three seconds to be made. Although this
effect enables a variable mixing adjustment between the original signal and the
delayed signal, it is developed for use with the signal 100% delayed. Intermediate
situations generate a typical comb type filter effect. The adjustment of the “Regen”
parameter to 100% naturally produces signal feedback. This parameter must be
adjusted to 0% for use in synchronizing signals.

•
Compressor/Limiter. The main application for this effect is that of a limiter, since it
is a compressor that only acts above the previously set threshold level. Below the
threshold level, the signal will only be affected by the gain that is applied. When you
use this effect as a limiter, we recommend adjusting the gain to 0 dB, the
compression range to the maximum (1:50) and the threshold to the level above
which you wish to limit the signal (typically between 0 and +6 dB). The adjustments
to the “Attack“ and “Release“ time are described in greater depth in the configuration
software manual. “Gain“ parameter settings above 0 dB are appropriate for very low
compression threshold settings. This makes it possible to have a uniform level for a
background sound—typically, the international sound of an event broadcast.
Noise Gate. The noise gate is an expander that acts below a certain threshold level,
drastically reducing the levels below that threshold. This allows the background
noise in a given signal to be eliminated. When the noise gate is used with voice
signals, you will need to be especially careful when adjusting the times (“Attack“,
“Release“, “Hold“) so as not to cut off the beginnings or ends of utterances.
In the Process Menu screen you can manage groups of presets for the signals selected.
For the preset group of each one of these effects, the action options associated with
each of the pushbuttons (21) are as follows:

3.2.3.2. Memory Configuration.
Depending on the type of configuration that was sent from the configuration software,
the main display will show either the “Working Configuration” option or the “Config.”
option. Thus, the “Working Configuration” option will be accessible by default when you
have a standard configuration in the controller board, while the “Config.” option will be
accessible by default if a configuration is sent that works with memories.
In both cases, access to these two options is associated with the second pushbutton
from the left (22) in the main display. This section describes the memories working
mode.
A memory is a form of instant storage of the settings of each of the controls of all the
channels on the control surface (except input gain, phase and mode). This means that,
when a memory is created, the system saves the situation of the control surface at that
moment with respect to all the channels. To retrieve the stored situation, you simply
load the desired memory. Because the change to a previously stored memory is
practically instantaneous, no audio losses occur.
The use of memories is especially appropriate when you need simultaneously to
change the settings situation of several channels that depend on more complex
operating functions than the mere activation of an effect or a channel. You will obtain
maximum performance when you create memories that store different assignments of
signals to channels, with different routing assignments for each channel. In a radio
broadcast, different programs may coexist during the day with different requirements
and mixer use situations.
If the option shown in the main display is “Config”, when you select the relevant
pushbutton you will access the memory management screen. From this screen you can
also access to “Working Configuration” management screen.
The options available to you for managing memories are basically: save, load and
delete. The procedure to follow is:

ƒ
SCROLL: Use the encoder associated with this option to select a memory position,
which may or may not be already occupied.
SELEC NEW: Press the encoder to validate your selection.

occupied or not, the system will store the settings situation existing at that moment
on the control surface.
ƒ
LOAD SELECTN.: If you wish to load a previously stored memory, use “Scroll” and
“Selec New” to select the memory you want to load. Then press “Load Selectn.” and
the control surface will reconfigure itself to the settings stored in the selected
memory. If any channels are active (On Air) at that time, the settings will be
loaded for all the channels except the active ones; in those channels the “On
Air” indicator will blink during memory loading to indicate that they won’t be
modified.
DELETE SELECTN.: Erases the memory previously selected by using “Scroll” and
“Selec New”. The system displays a warning message indicating that the selected
memory is about to be deleted.

3.2.5. “Macro Configuration“ display. Load and activation of programmable keys.
Macro files contain the definition of assigned functions for the programmable keys. Due to the
complexity involved in programming macro functions (IP address, protocols, timers, etc.),
programming cannot be done from the surface control, but must be done from the
configuration software.
Work with macro files is therefore limited to loading and activating the respective keys
configuration. Bearing in mind the fact that there are 32 programmable keys, the macro file may
not have all of the keys defined. In this case, the keys that are not defined will be able to
maintain their previous configuration or be forced to “Empty“ (they will not perform any action).
To access to “Macro Configuration“ option, from the main screen press under the “MACRO
CONFIG” label (pushbutton P3). Then a screen will appear, as shown on the upper left figure,
showing a list of the macros defined by means of the configuration software. To select the
desired option the usual procedure must be followed. Using the lower encoder labeled
“SCROLL” select the desired macro. Once the macro is selected (it appears highlighted on the
list), press the encoder (“SELECT NEW”). The selected macro label appears in the “New
Selected” area. Press “LOAD SELECTN.” to load the new macro A confirmation screen will
appear: press “YES” to load the new macro or “CANCEL” to abort the loading process

3.2.6.1. IP addresses change.
The first parameter on the list is “Mixer Address“, which allows you to change the
control surface IP address. The second parameter is “Frame address“, which allows
you to change the frame IP address.
An IP address is set up for the control surface (“Mixer ID“) as well as for the frame that
actually contains the mixer (“Frame ID“), with the aim of establishing the communication
through an Ethernet, among the different elements of the BC 2000 D system and also
with the software configuration. This means among other things that it can be set up a
remote connection with the system through Internet, if it is necessary, with the aim of
configuring the system.
In its most simple configuration, the mixer controller (Frame), the surface control (Mixer)
and the PC utilized to set up the system configuration, can be linked through an
Ethernet switch with RJ-45 connectors and establishing the corresponding IP address in
every element of the system (e.g.: 172.031.000.xxx).
In the most advanced configuration, it can be set up a system with several mixers and
control surfaces, and controlling through Internet by means of a PC from any point in
the net, providing that the communication among the different devices will be properly
set up. To do this, it will be necessary to establish a subnet mask (“Mask“) and the
“Gateway“ to access the system.
The procedure to change the IP address is the same for both the control surface and
mixer controller. By rotating the encoder located on the right of the screen (21), the
highlighted values are changed. Pressing the encoder accepts the changes and skips to
the following parameter, which will be highlighted. Keep repeating the previous step
until all required values have been reached. In the case of the mixer, the upper encoder
will make it possible to change the IP address, the middle one the subnet mask, and the
lower one the gateway.
To exit either screen without changing the IP address, press “CANCEL“. Press “OK“ to
accept the changes and exit the screen. Pressing either “OK“ or “CANCEL“ will lead you
to the main “System Setup“ screen.

and skips to the following parameter which will be highlighted. Months, days and years
can be modified inside the “DATE SET” menu, and hours, minutes and seconds, in the
“TIME SET” menu.
To exit either screen without changing the date or time, press “CANCEL“. Press “OK“ to
accept the changes and exit the screen. Pressing either “OK“ or “CANCEL“ will lead you
to the main “System Setup“ screen.
3.2.6.3. Information about Firmware versions.
The following screen shows the information corresponding to the different firmware
versions installed in the different available consoles. The information available is, for
DM console (“CONSOLE 0”), the firmware versions of Rabbit (“Communication
controller”), DSP (“Audio Processor”), microcontroller (“Mixer Controller”) y FPGA
(“Programable Logic"). “Controller” firmware version (“Frame”) is also shown. For D10
consoles (“CONSOLE 1” and the following) microcontroller and FPGA versions are
shown.
It is not possible to modify any of the parameters in this screen, they are just used to
acquire information about the firmware installed in the system.

3.2.6.4. DSP% CPU Used.
This screen displays the type of function performed and percentage of CPU used by
each installed DSP board. Each DSP board performs a certain function, which may be
signal routing (MATRIX), VU meter calculation (VUMETER), effects applied to audio
signals (PROCESS) or backup. Next to the position occupied by each board in the
frame, the screen indicates the function assigned to it and the percentage of resources
it uses.
3.2.6.5. Disconnect all audio process.
This function executes a general deactivation of all the audio effects applied in the
system, that is, it switches from ON to OFF all those effects that are activated. In no
case does it modify the values of each setting applied to the various presets of each
effect in each signal.
Selecting this option brings up a warning message indicating that there are only two
options: “OK“ or “Cancel“. If you select “OK“, all the effects that are active at that time
are directly deactivated.
3.2.6.6. DSP Output list.
For each DSP board, a list is shown of the set of outputs that the board is processing.
To display the different boards that execute routings and the outputs processed by
each, simply rotate the encoder associated with the DSP Scroll function.

3.2.6.7. Signal Processing Changes.
This option allows you to monitor the changes regarding parameters (phase, mode and
balance) and processes (dynamic, equalization, filtering and test signals) of each one of
the control surfaces channels in relation to initial configuration (or to the last one
accepted). It also allows you to accept those changes or undo them and fall back to the
last accepted configuration.
This function is available only when “Changes Monitoring” option is active in the
configuration you sent (if this is not active, the system allows you to access to “Signal
Processing Changes” option but the changes list will always be empty).
When a change of parameters or processes is done in any of the control surfaces
channels, a blinking warning signal is shown in the special functions display of the DM
control surface (up on the left). If you select “Signal Processing Changes” option in
“System Setup”, a list of “Signals” and “Changes” will be shown
Then you can accept changes or undo them and fall back to the last accepted
configuration; you can make this approval of changes for all the listed signals, by
pressing “ACCEPT ALL”, or just for one of them (the one selected in the list), by
pressing “ACCEPT SIGNAL”. In this way you can also undo the changes for all the
listed signals by pressing “RESTORE ALL” (in this case the system asks the user for a
confirmation) or just for the one selected by pressing “RESTORE SIGNAL”.

different purposes.
The following screen is displayed when P1 button is pressed on the System Setup screen.
The following functions are available when P1 to P5 buttons are pressed:
1. Start/Stop: The “Clock” count is established by pressing the button below this label. It
serves the same function for the ”Timer” function.
2. Elapsed: It keeps fixed the value displayed on the screen at the moment to press the
“Elapsed” button, but the count clock continues in background (in both functions:
”Timer” and ”Clock”).
3. Reset: Set up the count to zero.
4. Timer/Clock:: It changes between ”Timer” and ”Clock” options. When access to this
screen the default option is ”Clock”.
5. Main Screen: Return to main screen.
In ”CLOCK” mode, it works as a
chronometer with hours, minutes and
seconds. Pressing ”START” (push-button
P1) the chronometer is initiated. If pushbutton P1 (now “STOP”) is pressed again,
the count finishes. When pressing ”START”,
the ”ELAPSED” label appears on its right. If
push-button P2, below this label, is pressed,
the chronometer display is stopped but the
count continues. To begin the count again
and to set up the chronometer at zero, the
push-button P3 below the ”RESET” label
must be pressed. To change at ”TIMER”
function, the push-button P3, below the
”TIMER” label, must be pressed.
In ”TIMER” mode, it works as a countdown
timer. By default, the timer appears as a 1
minute countdown.
On this screen, the ”SET” option permits to
adjust the timer length. This is carried out
using the rotating encoders (21). The upper
E1 push-button adjusts hours, the
intermediate E2 adjusts minutes and the
lower E3 seconds. When selecting ”START”
the countdown begins. The other functions
are the same as described for ”CLOCK”
mode.
When user leaves to “MAIN SCREEN” it does not stop the CLOCK or the TIMER, in such a way
that the up or down count continues.
