Product Overview
The AEQ CAPITOL makes digital technology available to radio and
TV stations where digitalization has still not been feasible. AEQ CAPITOL was conceived taking into account our customers needs for a
versatile, powerful, easy to use and not less importantly, very cost
efficient digital mixer. Based upon the AEQ ARENA y FORUM digital
mixing consoles that are currently in service at thousands of studios
of both medium and high level, AEQ CAPITOL offers the same performance as the FORUM but in a “fixed” format; perfectly adapted
to the real needs of the majority of stations but with a limited number of options.
Main Features
Just as the FORUM, the AEQ CAPITOL is a digital audio mixing console specifically designed to meet the most rigorous demands of the
radio and television broadcast industry. Its flexible design allows it to
be readily adapted to any ON-AIR application.
The AEQ CAPITOL incorporates all of the features necessary at the
majority of stations: automatic monitor speaker cut-off, cough
muting, fader-start, control signalling, interface signalling for automation of external equipment, external communications management,
intercom, etc.
This compact console solution consists in a control surface and a
2RU mixer engine. There are two versions of the CAPITOL control
surface; a counter-sunk control surface that measures only 48,26 x
35,6 cm - 19"x14” (8RU) and a Desktop version with wooden side
panels - 56x46 cm - 22x18”. Thanks to its design and reduced footprint, AEQ CAPITOL adapts perfectly to any environment: auto-control, studio control, television production, sound production, mixed
configurations, integration in large installations, etc.
The CAPITOL’s control surface with its 8 faders and complete control sections can be substituted or supplemented with “VIRTUAL
CAPITOL”, a Windows based software application. The application
faithfully reproduces every detail of the control surface and all the
operational features of switches, rotary encoders and faders. It also
shows all information and internal menus that are visible in every
display of the physical control surface. This application opens new
possibilities to install fully remote controlled equipment at more
than affordable prices. Used as a remote control, the application provides the user with total control of all the features and functions of
the mixing console - including the remote representation of the Vumeters. Truly, the CAPITOL can be used in a completely unattended
broadcast station!
One of the primary features which sets the CAPITOL apart is its internal routing capability in combination with the available number of
inputs: 4 selectable Mic/Line Inputs, 12 Analogue Inputs, 4
AES/EBU Digital Stereo Inputs, 2 USB Digital Stereo Inputs for broadcast automation, 2 optional Inputs through Digital telephone
Hybrids and an additional 64 input signals via an optional MADI
multi-channel fiber-optic link.
The Output section of the CAPITOL is not less impressive; 8 analog
Outputs, 4 AES/EBU Digital Stereo Outputs, 2 USB Digital Stereo
Outputs for broadcast automation, 2 optional Outputs through
Digital Telephone Hybrids and optionally an additional 64 Outputs
signals via a MADI multi-channel fiber-optic link. Further, the console counts on Outputs for Control room headphone, Studio primary
and secondary Headphones, Control, Studio and CUE monitors.
Each of CAPITOL’s basic functions such as setup, level adjustment,
and signal routing have their own specific control for each channel.
Less used settings are grouped into contextual controls common for
all channels and are accessible by just one or two button pushes:
simplicity and ease of use provides for very dynamic system control
and greatly reduces operator error.
CAPITOL’s configuration allows any signal present within the system
to freely be assigned to any control channel and signal distribution
and routing configuration is done on the control surface itself.
Signals that are not assigned to any specific channel can even so be
routed with total flexibility. Input and Output levels can also be easily
CAPITOL has a built-in memory bank where each signal’s settings
are stored: signal distribution via the control surface, output bus
routing, setup parameters, effects, etc. This allows the console to
easily be adapted to different programming needs and unique technical requirements.
The Ethernet connector enables external connectivity for the optional software applications "AEQ CAPITOL Configuration" and "VIRTUAL CAPITOL" that provides the mixer with a powerful remote control.

As with the rest of AEQ’s audio mixing consoles, a major design consideration of the CAPITOL was its ease of installation and configuration. Therefore its 2RU auto-ventilated audio engine can be installed wherever required. The only communication link required between the engine and the control surface is a CAT-5 cable.
CAPITOL’s flexible I/O capabilities allows it to be interfaced with
external devices for cough muting, device remote control, ON-AIR
lights, etc. by using its General Purpose Inputs and Outputs. CAPITOL is well prepared with a total of 8 opto-coupled GPI’s, 8 optocoupled GPO’s and 4 GPO’s with relays.
CAPITOL also has a built-in Ethernet port for configuration and control through Software applications for Windows based PC’s.
For monitoring and control, the CAPITOL audio engine has a set of
pre-defined I/O´s for Control room Headphones, Studio primary and
secondary Headphones, Control, Studio and CUE monitors. It is possible to configure an additional bus to be used for secondary headphones monitoring and that will provide for independent talkback
and control intercom.
The Basic audio Inputs and Outputs are:
• 4 mic./line mono inputs, configurable with phantom power.
• 2 USB (I/O) digital stereo inputs
• 4 AES/EBU digital stereo inputs that can be configured as SPDIF
• 12 analog inputs (can be configured as mono inputs or as 6 stereo inputs)
• 2 USB (I/O) digital stereo outputs

Control Surface (Channels)
CAPITOL’s control surface provides 8 channel faders and an area
dedicated to signal adjustments, programming, monitoring and talkback.
The surface consists in an 8RU panel with normalized 19" width.
The CAPITOL control surface comes, as previously mentioned in two
versions; either integrated in a desktop chassis with white wooden
side-trims , providing the control surface with an ergonomic inclination for the operator or; without desktop chassis, as an 8RU 19” control surface to be counter-sunk, horizontally integrated with the the
studio furniture desktop.
All of CAPITOL’s signal channels are completely user-definable.
System signals can easily be assigned and re-assigned to the channel faders; a particular channel can control any given signal at one
moment and a different one in another. This facilitates unique signal
to channel distribution, and allows CAPITOL to be easily adapted to
distinct programming requirements and to suit different operational
CAPITOL packs a tremendous amount of power and flexibility into its
small footprint. In addition to signals present on the control surface
which can be mixed, processed, and sent to any output channel,
CAPITOL can adjust the level and routing of all its available physical
channels, including those that are not “visible”, i.e. not assigned to
any specific channel.
At the top of each channel section there are 2 routing buttons and
1 channel selection button that is used to assign the channel to the
common controls for the advanced configuration parameters: (gain,
dynamics, equalization, balance, and send to Auxiliar channels or
Next is an OLED display screen which shows the channel’s name
and status as well as the balance level. Beneath, a CUE button along
with a LED that indicates activity or applied process, i.e. equalization,
filters, dynamics and gain. Finally, the last two elements are the
channels on/off button that at the same time serves as the channel
ON-AIR status indicator and the 100 mm (4”) fader.
