AEQ ARENA
DIGITAL AUDIO MIXER
FOR RADIO BROADCASTING APPLICATIONS
Main Features
The AEQ ARENA is a digital mixing console for radio broadcasting
applications. It is especially designed for controlling on-air transmissions, and is adaptable to different working situations that arise in
today's radio operations. The ARENA includes all the basic features
needed in this sort of environment: automatic monitor cut-off, cough
muting, fader start, control signalling, control signals for the automation of external equipment, external communications management,
intercom, etc.
Thanks to its special characteristics, it easily adapts to different working configurations: autocontrol (self-op), control room-studio, control
associated with several studios, mixed configurations, integration
into large facilities, etc.
One of the most important virtues of this mixer is its routing capability. The system can make more than 30,000 crosspoints. This
routing power makes it possible, for example, for all the system outputs to be summable and re-routable to other outputs; it enables as
many n-1 buses or clean-feeds to be created as there are available
outputs,
Simplicity and control power are combined to make both the most
basic and advanced operating tasks easy.
The flexibility offered by the configuration of the ARENA allows the
assignment of the signals present in the system to any control channel, and the modification of that signal distribution can be done from
the control surface itself.
THE ARENA CONSOLE WITHIN THE BC 2000 D SYSTEM
The BC 2000 D is a system that can function either as a router or as
an audio mixer controlled by the ARENA control surface. The main system components are the same for both. Just by using different
firmware, the system can work as a powerful router or a versatile mixer.
With the BC 2000 D, systems can be configured that control, process
and route all the audio in a programme production centre, even if it is
spread across several facilities within a radius of at least 10 kilometres.
The ARENA Console is used as the mixing console in the studios and
the matrix is controlled by X-Y panels or software applications.

INTRODUCCIÓN
Power and Development
One of the fundamental concepts on which this digital system is
based is the differentiation between control and signal processing.
The mixing, processing and, in general, the treatment of audio signals executed by the main BC 2000 D engine. The ARENA control
surface provides the control for the mixing system.
With this in mind, the system is scalable according to requirements.
Users can implement a range of set-ups, from a system with a very
few inputs and outputs to one with more than 100 inputs and outputs. Similarly, the control surface can comprise a system with a
greater or lesser number of channels, according to the users' needs:
from five to seventy-five physical fader channels.
The new ARENA control surface was developed from the original
BC 2000 D mixer control surfaces. With this new control surface,
notable improvements have been introduced into the system, such
as the possibility of monitoring all the signals present in the system,
or the use of memories.
The ARENA incorporates improvements in its exterior design such as
dedicated power supplies and styling, in operational capacity and in
modularity. During installation, the user can now decide whether they
prefer the ON/OFF controls beneath the faders for quicker access, or
above them for greater security, since the surface has been
redesigned to make it more versatile and adaptable to any situation.
The latest features introduced enable the controls for each channel
on the control surface to provide direct access to the main output
buses or to the principal system functions. Direct front-panel access
has also been facilitated to make maintenance work easier.
The ARENA also includes all the functions that were previously
implemented in the BC 2000 D system, such as the option of simultaneously controlling several studios, or for example, as a Mix-Minus
mixer with an unlimited number of n-1 circuits. In this operational
mode faders are configured as I/O channels.

ARENA DM
Two ARENA control surfaces are available: ARENA DM and ARENA D10. The DM has five
channels and a control and monitoring section for all the signals in the system. The D10 has
ten channels. Up to seven ARENA D10s can be linked to an ARENA DM. This makes it possible to create systems composed up to seventy-five fader channels. However, thanks to the
use of pages and motorised faders, users can control a great many signals with a single DM
control surface and just one or two D10 control surfaces.

Pages and Memories
PAGES
More Control in
Less Space
Thanks to digital technology, the page concept provides users a greater number of signals in the final mix, with no need to have the
corresponding control physically in sight. As the transition from one
page to another is practically instant, not having direct physical
access simultaneously to all channels is clearly offset by the saving
in controls and space. The use of pages allows a better organisation
of the distribution of signals assigned to
each channel.
When one of the page change buttons is
pressed, the channels present on the surface are replaced by the channels assigned to
the new page, and the labels, fader positions and settings corresponding to each signal change automatically.
Each surface has capacity for up to nine pages. This makes it possible to simultaneously control as many as 45 signals on a single DM
surface, and up to 90 on a D10 surface. Furthermore, the user can
directly route any signal to any output without having to assign it to
a control channel.
Of course, the assignment of signals to channels is totally user-definable. The user can also pre-assign any number of signals present
in the system to one or more channels. In other words, a single
channel can control a given signal at a certain time and another (different) signal at later on. This enables users to reorganise the distribution of channels so that the system can be adapted to different
uses or programmes. In addition, the various assignments of signals
to channels can be stored in memories for subsequent use
MEMORIES
ARENA users can work with memories that store the settings of each
signal assigned to the channels on the first page. Since the system
is especially designed for on-air applications, the change from one
memory to another is protected so that the signals that are being
broadcast remain unaltered. The transmission is thus never lost.
The use of memories makes it possible to adapt the system for the
production of different programmes involving different technical
requirements. The distribution of the signals over the surface is stored, as are the routing of each of those signals to the different output buses, or the parameters and activation of different digital FX.

Ease of
Operation
Monitoring and
Main Section
MAIN SECTION
The DM control surface has an additional display for general system
administrative functions. This is a dual-purpose display, since the
Select key for each channel can also be used to apply dedicated
functions to a particular signal in a more precise way.
Among the functions are the control of DSP resources, IP address
management, configuration and memories administration, the overall control of effects, the display of installed firmware and other utilities such as a timer, stopwatch .and clock
The Select key for each channel enables the execution of functions
associated with the selected signal in the ARENA DM main display.
These functions include specific signal settings, such as phase changes or to enable Phantom Power (if the signal in question is a microphone signal). The Select key also serves to insert a test signal (tone
or noise) and to activate and adjust audio effects: equalization, filters, limiters, etc.
MONITORING
The ARENA control surface has a multipurpose screen that shows
parameters that are specific to each channel, the routing of the signals present on the surface, and a VU meter for each signal present
on the surface.
A multi-studio situation can be defined that enables ARENA users to
manage two or more studios independently from a single control
room. This includes independent, centralised control of the ON-AIR
signalling, the signals assigned to the monitors and headphones, the
levels of those monitoring circuits, cough muting, remote PFLs, etc.
The DM control surface also offers two high precision digital VU
meters that can be assigned to any signal. By employing programmable keys, the user can dynamically assign different signals to the
main VU meters. Additionally, the DM control surface display has a
VU meter dedicated to the CUE signal with an associated phase
meter.
The ARENA DM has two sections for monitoring of the control room
and the studio(s) that have been defined. In these sections there
are independent level controls for the control room monitor, studio
monitor and whatever headphone monitor circuits may have been
defined in the system, as well as the CUE monitor speakers built into
the surface itself.

PROGRAMMING ADDITIONAL FUNCTIONS
Ease of
Communication
The ARENA DM has a large area where users can program special
functions in a library that includes the definition of GPIs, GPOs, the control of hybrids and codecs, the management of different studios, etc.
Using the 32 available keys the user can also enable some of the
options explained previously such as sending signals to the main VU
meters or the establishment of additional communication circuits.
These programmable keys can also be used to completely convert
the mixer into a multiplex system where channels become input /
output channels, thus making it possible to manage whatever MixMinus or n-1 groups may be required.
TALKBACK
As a control surface, the ARENA does not contain audio signals
except for a few that permit the operation and control of the system.
One of these signals is the microphone input that includes its own
A/D converter. There are predetermined circuits between the
ARENA surface and the studio - an independent one for the monitors and two headphone circuits.
Additional talkback circuits can be set up in the system to make
communications management easier. For example, the user can
program the sending of the DM control surface microphone to the
various hybrid and audio codec returns.
This microphone input can also be used as an auto-control
(Self-Op) microphone if desired.

TOTAL ROUTING
ADAPTATION TO DIVERSE APPLICATIONS
On each channel,
users can activate
or deactivate the
sends, independently adjust the
relative levels of
all of them, and
individually modify, without limitation, the pre-fader
and
post-fader
assignment.
Any signal can be sent to any output, if the system is configured that
way. It is also possible to select which routings will be available to
the operator and which will be fixed.
The ARENA control surface adapts to different working modes.
Depending on the needs imposed by each situation, the controls
can perform different functions that will be suited to each purpose.
The control surface channel controls can be programmed to provide
access to typical functions, to work as direct routing keys, or be converted for use as I/O channels.
Additionally, the new ARENA is
physically configurable. Thanks
to its modular design, the user
can place the ON/OFF or CUE
buttons above or below the
faders on the same piece of
equipment.
The routing power of the system is so great that it enables its users
to work by sending all the inputs to all the outputs, in any combination, and to control all the basic routing parameters from the surface.

BC 2000 DF Frame Modules
BC 2230 CONTROLLER MODULE
The controller board is the brains of the system.
It receives power from the BC 2290 power supply, establishes control of the system, synchronisation and communications between the BC
2000 DF frame and the various components
installed in the network.
BC 2220 DSP BOARDS
Depending on the size and features of the system,
each frame will need between four and 20 of
these digital processing modules. The DSP boards
perform different types of functions: routing, mixing, signal processing effects, display of levels on
the screen, etc. They can be redundant to guarantee system operating continuity.
BC 2211
BC 2201 ANALOGUE AUDIO INPUT / OUTPUT MODULES
BC 2230
Each BC 2201 module consists of four analogue
inputs and four mono analogue outputs, which
can be defined at will as stereo signals. All these
inputs and outputs are electronically balanced.
The signals are connected by means of RJ-45
connectors, each of which groups together four
input and four output signals. Also available are
general purpose inputs and outputs that can be
used, for example, to control external equipment.
Four GPIs and four GPOs are present in two RJ45 connectors oneach I/O board.
There are also modules available with only four
analogue mono inputs (BC 2204) or only four
analogue mono outputs (BC 2205).
BC 2202 DIGITAL AUDIO INPUT / OUTPUT
MODULES
BC 2202
This module provides four digital stereo inputs and
four outputs in AES/EBU format, which are individually configurable as SPDIF format signals. They are
all insolated by transformer and have independent
sample rate converters (SRC) for the input and output; the sample rate of each of the outputs can be
individually configured.
A BC 2202 module is responsible for controlling
the basic signals of the ARENA DM surface:
main VU meters, control headphones, talkback
microphone and CUE monitors. Like the rest of
the input / output modules, the BC 2202 has
four GPIs and four GPOs.
Also available are modules with only four inputs (BC
2206) or only four outputs (BC 2207).
BC 2203M ANALOGUE MICROPHONE AND
LINE INPUT MODULE
This module provides four mono inputs that are
configurable as microphone or line inputs; they
are all electrically insolated by transformer. Each
input can supply phantom power required for
electrostatic microphones. This module also
offers four GPIs and four GPOs. Phantom power
and mic / line switching are activated from the
ARENA control surface.
