MAIN DESCRIPTION
Fox is a fully digital audio changeover, designed for Radio and TV broadcast marketplace.
Fox matches the most hi-end broadcast use requirements, with two analog inputs, two digital inputs, one analog output
and one digital output. All the inputs can be routed to a different audio output thanks to the A/D and D/A converter, so
that any kind of switch between different inputs can be managed.
Switching policies between inputs and outputs are fully user-configurable in order to suit individual requirements.
Furthermore Fox plays inside the entire audio chain the delicate role of program supervisor, thanks to an integrated
audio detector and the ability to generate an alarm when the nominal operating conditions are not met. When an alarm
rises, a switching command via GPO is provided. Fox presents in the front side a graphic LCD display that shows the
levels of analog and digital inputs and outputs and the alarms detected during the normal use.
The control software comes for free with Fox and allows the configuration of the timing and the policy of
intervention/recovery of switching, displaying levels of input and output signals and configure every working
parameter. It is also possible to save the data to a single device and create a database for all the Fox in operation into
the chain.
The process is based on DSP audio and the audio features included are: Denoiser, that eliminates unwanted noise on
the audio chain; the Delay module, a delay line applicable to a fully synchronous input in order to keep all audio sources.
During the process of allignement and calibration of the audio network, a Tone Generator generator with variable sample
frequency and amplitude is is provided with Fox and available on Analog and/or Digital outputs. Furthermore, a DTMF
encoder and a DTMF decoder with customizable strings, allow the remote management of automation systems.
The Fox’s rear panel is provided with XLR conneters, for balanced analog and digital AES/EBU signals. The outputs are
equipped with hardware bypass. In case of fault of the equipment the main analog input is directly routed to the analog
output and the main digital input is routed to the digital output.
In order to set up and use Fox, the connection to a Pc it is possible via RS232 remote serial port, USB connection and a
simply logic state via GPIO port with open collector and opto couplers that are representing the operational‘s states of
any alarms, along with command automation equipment using DTMF decoding strings. Optionally, it is possible to install
an Ethernet port and use the SNMP - TCP/IP protocol, in addiction to the web server installed on board that allows to
display the equipment status via a common web page.
Universal Power Supply 90-264Vac 47-63Hz that can operate in any region of the world. Fox takes up 1 rack unit
standard 19 "

2 SAFETY WARNINGS
The installation and servicing instructions in this manual are for use by qualified personnel only.
-
Read All Instructions. All safety and operating instructions must be read before operating the product. They also
must be retained for future reference, as it contains a number of useful hints for determining the best combination of
equipment settings for Yr particular application.
-
Heed All Warnings. All warnings on the product and those listed in the operating instructions must be adhered to.
-
Heat. This product must be situated away from any heat sources such as radiators or other products (including
power amplifiers or transmitters) that produce heat.
-
Power Sources. This product must be operated from the type of power source indicated on the marking label and in
the installation instructions. If you are not sure of the type of power supplied to your facility, consult your local power
company. Make sure the AC main voltage corresponds to that indicated in the technical specifications. If a different
voltage (ex. 110/115 VAC) is available, open the equipment closure and set the voltage switch on the main supply
circuit, located behind the AC socket
-
Power Cord Protection. Power supply cords must be routed so that they are not likely to be walked on nor pinched
by items placed upon or against them. Pay particular attention to the cords at AC wall plugs and convenience
receptacles, and at the point where the cord plugs into the product
-
Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When
a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
-
Lightning. For added protection for this product during a lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the AC wall outlet and the audio connections. This will prevent damage to the
product due to lightning and power line surges
-
Installation. Configuration and installation should only be carried out by a competent installation engineer
-
Cabling. Using high quality wires, well protected. Make sure the cable integrity.
This symbol alerts you to the presence of dangerous voltage inside the closure –voltage which
may be sufficient to constitute a risk of shock. Do not perform any servicing other than that
contained in the operating instructions. Refer all servicing to qualified personnel
The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the
appliance.
Do not change the voltage setting or replace the mains fuse without first turning the unit off
and unplugging the mains cord
Make sure the AC main voltage corresponds to that indicated in the technical specifications.
THIS APPARATUS MUST BE EARTHED !
To avoid risk of fire use the correct value fuse, as indicated on the label stuck on the right
side of the unit.
This apparatus uses a single pole mains switch and does therefore not separate the unit
completely from the mains power. To completely separate from mains power (in the event of
danger) unplug mains power cord. As the MAINS plug is the disconnect device, the
disconnect device shall remain readily operable.

Ce symbole indique la présence d'une tension dangereuse dans l'appareil constituant un risque de
choc électrique.
Ce symbole indique que la documentation fournie avec l'appareil contient des instructions
d'utilisation et d'entretien importantes.
Avant de modifier le commutateur de changement de tension ou replacer le fusible il faut
débrancher l’appareil de la prise électrique. Pendant son usage, l’appareil doit etre branchee à la
prise de terre
Utiliser le fusible principal AC avec le valeur qui est indiquée sur l'étiquette collée sur le coffret.
