COMPACT DIGITAL AUDIO MIXER
FOR RADIO AND TELEVISION
Product Overview
The FORUM Compact Digital Audio Mixing Console represents the culmination of AEQ’s many years of technological development and experience producing the highest quality digital consoles
for the broadcast industry. It is based upon our ARENA Digital
Console found in use at hundreds of high-level studios. Our valued
customers asked us for a powerful, versatile, yet simple product to
digitally replace analog consoles found in most radio and television
studios today. FORUM offers just that – an unprecedented feature
set, extremely simple installation and configuration, coupled with
intuitive and totally agile operation.
Main Features
The FORUM is a self-contained 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 readily be
adapted to any ON-AIR application.
FORUM incorporates all of the features necessary for use in environments requiring: automatic monitor speaker cut-off, cough muting,
fader start, control signaling, interface signaling for automation of
external equipment, external communications management, intercom, etc.
Thanks to its self-contained modular design and reduced footprint,
FORUM adapts perfectly to any environment: auto-control, studio
control, television production, sound production, mixed configurations, integration in large installations, etc.
One of the primary features which sets the FORUM apart is its internal routing capability: any combination of 64 inputs/outputs of analog, digital, or microphone, plus an additional 64 input / output signals via a MADI multi-channel link.
Simplicity and control are combined in FORUM to satisfy ease
of operation - from the most basic to the most advanced requirements. The control surface can be configured with a minimum of 4
faders, and easily expanded to 8 or even 12 channels. (up to 16 and
20 channels with the FRGRAND chassis).
Each of FORUM’s basic functions such as setup, level adjustment,
and signal routing have their own specific control for each channel,
while lesser used settings are grouped into contextual controls common to all channels and are accessible by just one or two button
pushes: simplicity and ease of use makes for very dynamic system
control with little chance of operator error.

FORUM’s configuration allows any signal present within the system
to be freely assigned to any control channel, and signal distribution
configuration is done on the control surface itself.
FORUM has built-in memory 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.
Two Ethernet connectors enables external connectivity for the "AEQ
FORUM Configuration" software application. Further, these ports can
also be used for the optional software application "VIRTUAL
FORUM", that provides the AEQ FORUM with a powerful remote
control.

A major consideration in the design of the FORUM was its ease of
installation and configuration. Hence it is self-contained and has a
low profile format – it can be countersunk flush into a work surface,
or simply placed on top of it.
FORUM’s flexible I/O capabilities allows for the interfacing with
external devices for cough muting, device remote control, ON-AIR
lights, etc. by using its 8 monitor inputs (GPI), 8 control outputs
(GPO), and 4 output control relays.
For monitoring and control, FORUM’s mainframe has built-in outputs
for both studio and control room headphones and speakers, and a
microphone input for auto-control or coordination.
Analog Input Modules
Digital TELCO Hybrid Module
FORUM’s mainframe also has two built-in Ethernet ports for configuration and control.
For general purpose audio inputs and outputs, FORUM can be fitted
with a bi-directional MADI fiber-optic interface capable of handling
up to 64 digital inputs and outputs. FORUM also has 14 slots to
accommodate input / output modules including: digital, analog,
microphone/line, and TELCO hybrids.
To facilitate cabling, optional audio and data cables with mating DB
connectors are available.
Low profile self-contained format – can be used on top of or embedded into the work surface.

Control Surface (Channels)
FORUM’s control surface is modular. Each fader module contains 4
independent faders. The control surface can accommodate a basic
4 fader, an intermediate 8 fader, or a fully populated 12 fader
channel configuration. (up to 16 and 20 channels with the
FRGRAND chassis).
FORUM 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,
FORUM can adjust the level and routing of up to 128 x 128 embedded audio signals.
All of FORUM’s signal channels are completely user-definable.
System signals can be assigned to channels so a particular channel
can control one signal now, and a different signal later on. This facilitates unique signal to channel distribution, and allows FORUM to
easily be adapted to distinct programming requirements and to suit
different operator´s needs.
At the top of each channel section are 4 routing buttons and 1
channel selection button which are used to assign common advanced configuration parameters: (gain, dynamics, equalization and
balance).
In addition, signal/channel configurations can be stored in memory
allowing any configuration to easily be recalled for use in a particular scenario or by a particular operator.

Next is an OLED display screen which shows the channel’s name
and status as well as the balance level. Beneath it is a CUE button,
along with 4 LEDs which indicate activity or instability on equalization, balance, dynamics, gain, and finally an illuminated ON-AIR status indicator. The channel section ends with the fader itself and the
channel’s on/off buttons.

ADDITIONAL FUNCTIONALITY
FORUM allows the user to program pre-defined special functions such as: defining GPIs
and GPOs, controlling hybrids and codecs, sending signals to the VU meters, or setting up
additional intercom routing. 15 programmable keys are provided to enable/disable the
programmed function assigned to that key.
ADVANCED CONFIGURATION DISPLAY AND CONTROLS
Each of FORUM’s fader channels has an advanced settings button. Configuration is carried
out by using the multi-function integrated OLED display in the monitor and control section
on the right side of the console. The rotary encoder associated with the display is used to
scroll through the contextual graphics menus.
Dual asignable
precision VU meters
General functionality includes adjustment
and instantaneous activation of audio effects:
equalization, filters, limiters, etc., memory
management and configuration, general
effects disconnect, timer, stopwatch, phase
change, test signal insertion, etc.
MONITORING
The control surface also has two integrated
high precision digital stereo VU meters, each
of which can be assigned to display either
Master 1 or Master2/CUE outputs.
FORUM has two sections for the independent monitoring of the control room and the
studio. There are separate level controls for
control room speakers, studio speakers, and
headphones, as well as FORUM’s built-in
CUE speaker. FORUM´s studio and control
room monitor sections each have an OLED
display where selections can be seen.
FORUM includes independent and centralized control of ON-AIR signaling, signals assigned to speakers and headphones and their
levels, cough muting, PFL cuts, etc.

TALK-BACK
FORUM has independent pre-set intercom
paths between the console and the studio
for speakers and headphones.
Additional intercom lines can be established
to facilitate management of communication
within the system. For example, you can
send the talk-back microphone signal to individual hybrid and audio codec returns.
The talk-back microphone can be also used as
the auto-control microphone if so designated.
