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 tha
t 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
