Map the timing requirement
Work out whether the application needs visible time in the room, NTP distribution, LTC timecode, PTP synchronization or a combination.
Broadcast timing since 1984
NTP clocks for TV studios.
The exact time, impossible to miss.
We design and manufacture in Italy the synchronization systems that keep control rooms, studios and production teams aligned: NTP and LTC studio clocks, video clock inserters, NTP/LTC converters and PTP IEEE 1588 grandmasters.
Display NTP Clock for TV studiosThe reference time stays readable for everyone in the
room.
Choose your system
One accurate time. Every device in the studio in sync.
Start from the timing problem you need to solve and find the El-man system built for it.
Visibility in the studio

Why El-man
We design around your workflow.
From the control room to the distribution network, every installation needs the right interface, signal and level of accuracy. Since 1984 we have helped studios and broadcasters pick the reliable route, not the most expensive one.
- Timing built for broadcastNTP, PTP IEEE 1588 with SMPTE ST 2059-2 and AES67 profiles, LTC: the technologies professional environments actually use.
- Products made to integrateBuild a coherent timing path on the studio infrastructure you already have, without replacing it.
- Designed and built in ItalyHardware developed in-house in Rome: customizations, spare parts and firmware stay under our control.
- Technical support before you orderYou talk directly to the people who design the products and understand the application, not to a call centre.
A practical method
From a timing requirement to a system that works.
A clear path removes the guesswork before the equipment reaches the rack or the studio wall.
Fit the system to the infrastructure
Pick interfaces and products compatible with the existing network, the video chain and the operating environment, without rebuilding the installation.
Keep production aligned
Deploy a timing solution operators can rely on in the most critical production moments, with direct support over time.
Technical questions
Start from a clear answer.
These are the questions technical teams ask most often before choosing a timing system. If yours is not here, send it to us directly.
What does El-man design for broadcast environments?
Elettronica Mangione designs synchronized digital studio clocks (WiFi, LTC and SPT series), video clock inserters, NTP/LTC converters, PTP IEEE 1588 grandmasters, RGB LED displays and NB-IoT clocks for broadcast and professional applications.
When should you choose NTP and when PTP?
NTP is the practical choice for distributing time over a standard LAN with millisecond accuracy. PTP IEEE 1588 uses hardware timestamping and reaches sub-microsecond accuracy, but it requires compatible network equipment. El-man supports both routes, including the PTPMaster grandmaster.
Can a network time source feed LTC workflows?
Yes. The NTP/LTC converter receives the NTP reference over Ethernet and generates LTC timecode on a balanced 3-pin XLR output and an unbalanced BNC output, with programmable GPIO. The conversion is one-way, from NTP to LTC.
How do you insert a synchronized clock into the video stream?
The OSD inserter overlays clock, timer and timecode onto live video with hardware passthrough, on broadcast formats up to 1080p59.94. The source can be NTP or LTC, and the overlay is controlled in real time through the web dashboard, HTTP API or UDP commands.
Does PTPMaster support the SMPTE and AES67 broadcast profiles?
Yes. PTPMaster is a GNSS-disciplined PTP IEEE 1588v2 Layer 3 grandmaster with a hardware timer, supporting the SMPTE ST 2059-2 broadcast profile and AES67 for audio-over-IP. It can also act as an NTP Stratum-1 server for non-PTP hosts in mixed networks.
Do you need a local network to synchronize an El-man clock?
Not always. Studio clocks synchronize over LAN, WiFi or PoE from an NTP server, while the NB-IoT clock uses the Narrowband-IoT cellular infrastructure directly: it synchronizes on its own, with no cabling and no local network configuration.
Does El-man build custom systems?
Yes. Studio clocks come in a range of sizes, colours and mounting options, and systems can be customized around the needs of a specific room or infrastructure. The technical discussion happens before the quote, directly with the people who design the products.
