Special features

Connect “any” Kind of Sources

Tiger e3/e5 manages different kind of audio sources as Analog & Digital audio, IP-Audio, Backup-Player and MPX, thanks to the 4 channels audio changeover and 2 channel MPX Changeover.

The internal delay can be assigned to any source and allows the time alignment of two or more sources.It is possible to use the internal audio player as a backup if all the external sources fail.

The internal limiter continuously monitors the sources audio levels, allowing the level managing and avoiding any overshoot generated by the satellite or IP-Audio MPEG decompression.

MPX inputs are decoded (L&R) and available to be used as sources for the Audio Changeover or MPX Changeover.

MPX Changeover features a UECP filter that allows the regeneration or filtering of any RDS service (PS, RT,RT+,IH,TMC,TA/TP), thus giving the user the chance to maintain, replace or filter any RDS parameter starting from the incoming RDS signal.Changeover / FM Monitoring System with integrated Tuner.

TIGER E5 can manage and decode MPX and RDS signals, receive IP Audio streaming signals, receive and analyze Analog and Digital audio signals. Thanks to the 4 channels Audio changeover and MPX Changeover it can handle every kind of received signal in a transmitting site.

Easy Access

Tiger e3/e5 is fully configurable via WEB interface. Its web server is compatible with all the available web browsers (Chrome, Firefox, Edge, Opera, Safari…).

Tiger e3/e5 supports laptop, tablet and smartphones simplifying the browsing and setting of the device with its responsive-kind graphic interface that adapts the viewing mode according to the resolution and position (portrait/landscape) of the current viewing device.

The provided WiFi USB dongle creates a specific WiFi hotspot that enables the access to the device without the need of cabled or wireless net.

Tiger e3/e5 features 3 IPV4 and 3 IPV6 addresses to ensure concurrent connection for all the broadcasting and monitoring systems.

Easy Maintenance

Any first-time user can take advantage of Tiger e3/e5 simplified settings management. EASY CONFIGURATION FUNCTION quickly and easily enables the user to set the working mode, while QUICK RDS SETUP brings the mostly simple way to set the main RDS parameters.

IMPORT/EXPORT and PRESET MANAGER are available for a more advanced management of Tiger e3/e5.

These functions apply to the whole device configuration or only to some selectable modules (SYSTEM, RDS, MPX, AUDIO, MULTIMEDIA and TUNER).

Tiger e3/e5 uses a uSD card to create an automatic copy of all the device data whenever the user changes anything. If the device needs to be replaced or duplicated, the uSD card can be used to clone it.


Tiger e3/e5 features an endearing GUI (Graphical User Interface) that makes use of clear elements, rich of information. With a simple and straightforward selection of the available banners, it is possible to keep under control any function. The selected banners are always visible in any menu.

Tiger e3/e5 displays in both graphical and numerical format all the input and output levels as well as the internally generated signals. The visualization can be numerical, bar graph or time related.

In the RDS section, a specific area is available for on-air RDS group analysis (static and dynamic) to evaluate services balancing.

In the MPX section, spectrum analyzers display the MPX+RDS input and output signals.

Tiger e3/e5 provides two independent listening paths for every internal audio source:Local: using the headphone socket on front panel and the display to select the source.

Remote: using the internal IP audio encoder that enables the remote audio receiving with different listening quality choices.

The MPX decoder let the user listen to the decoded L&R audio for any of the MPX sources, input, output or internal.
