Supports SMPTE ST 2059-2 and AES67 profiles. - Can operate as PTP-only, NTP-only or PTP+NTP, and act as a local Stratum-1 NTP server. - Two hardware PPS outputs and a true IEEE 1588v2 hardware timer — not software emulation. - Real-time integrated web dashboard; OTA firmware updates over Ethernet; configuration persisted in EEPROM. ## NTP/LTC Converter URL: https://www.el-man.it/en/ntpltc.html Rack hardware device that synchronizes over LAN from an NTP reference and generates LTC timecode with millisecond precision for critical broadcast applications. - Outputs: balanced LTC on XLR and unbalanced LTC on BNC, compatible with any studio setup. - Configured via web interface; OLED display for status/config; reset button to restore default IP. - Powered at 5V via external adapter. ## NTP Remote URL: https://www.el-man.it/en/ntpremote.html Remote unit for video insertion with a 2-line 16-character LCD display, multifunction counter, backlit numeric keypad and Ethernet connectivity, designed for professional video production. - Counting modes: UP counter, Down counter and clock Timer, with dedicated PLAY, PAUSE, RESET and STOP keys. - Synchronizes over 10/100 Mbit Ethernet; compatible with NTP servers and LTC signal for timer alignment. - Universal 220V/240V power via external 5VDC adapter; battery-backed memory saves settings. ## LTC Displays and Studio Clocks URL: https://www.el-man.it/en/ltc.html Professional red-LED display panels (6 or 8 digits) to show LTC timecode across the studio, synchronizable via LTC or LAN, with excellent readability. - 6-digit version shows hours/minutes/seconds; 8-digit version adds frames. Available in 1U or 2U rack. - Synchronizes via NTP over Ethernet (RJ45) or via LTC signal; internal quartz clock ensures continuity without signal. - Automatic daylight-saving handling, web interface, OTA firmware updates over LAN. Universal 86–264 VAC power. ## TV Studio Clock / Video Clock Inserter URL: https://www.el-man.it/en/display.html Digital synchronized clocks showing precise time referenced to a master clock, NTP server or timecode source, in various sizes, colors and mounting options. - Series available: WiFi (NTP sync over LAN/WiFi), LTC (LTC timecode or NTP), and SPT timing-system series. - PoE power available on all WiFi Time Display models. - Complete systems can be customized to specific room requirements. ## Video Clock Inserter (OSD) URL: https://www.el-man.it/en/osd.html Inserts UP/Down timers and timecode directly onto the video signal with professional precision; ideal for studios and OB vans. - Supports SD, HD and 3G-SDI with NTSC, PAL, 720p, 1080p and 1080i; two SDI outputs and input loop. - Synchronizes via external NTP server or LTC signal, with bidirectional multi-speed LTC reading. - Customizable character size, color and position; transparent-background option; optional 4K/2K upgrade. Remote configuration over Ethernet; universal 86–264 VAC power. ## SPT System (Studio Production Timer UTC-R1) URL: https://www.el-man.it/en/spt.html Broadcast timing system with dual LED display for simultaneous time-of-day and timer display. - Multiple programmable timers in Up, Down, Offset and Diff modes, plus Local, Real-time, Date, Timer and Timecode views. - Synchronizes via NTP over LAN, with LTC and Ethernet connectivity, PoE support, and compatibility with external UD-series displays. - Programmable function keys and GPI inputs/outputs, web interface, automatic DST handling, OTA firmware updates over LAN. ## UDR2 red/green URL: https://www.el-man.it/en/udr2_red.html 6-digit UD display panel with red or green LEDs, the ideal complement to the UTC-R1 (SPT) timing system. - LED color (red or green) is software-selectable. - Synchronizes via NTP, with LTC and Ethernet LAN connectivity; remotable from the UTC-R1 (SPT) central unit. - GPI connector, automatic DST handling, web interface, OTA firmware updates over LAN. ## WiFi Studio Clocks URL: https://www.el-man.it/en/wifi.html Wall clock with a 6-digit red LED matrix display, synchronizable over WiFi or LAN. - Optimal readability up to 30 meters, with finely adjustable brightness. - Synchronizes via NTP over WiFi or Ethernet LAN; single-cable PoE power or external power. - Dedicated Windows software and web interface, wireless OTA firmware updates, automatic DST handling. Built on ESP32 microcontroller, metal enclosure 341×77 mm. ## NB-IoT Clock URL: https://www.el-man.it/en/nbiot.html Clock with an e-paper display that synchronizes automatically over a Narrowband-IoT cellular network — no WiFi or LAN required. - NB-IoT is an LPWAN (Low Power Wide Area Network) standard defined by 3GPP, the same body behind 4G/LTE and 5G. - Automatic global synchronization independent of local network infrastructure, with low power consumption and energy autonomy — ideal for autonomous IoT devices. ## BigClock URL: https://www.el-man.it/en/bigclock.html Professional RGB LED-matrix clock system (128×32 pixels) based on an ESP32-S3 microcontroller, for broadcast studios and professional environments. - DS3231 RTC with ±2 ppm precision keeps accurate time even offline; NTP sync provides millisecond accuracy when connected. - 16-bit color RGB display (65,536 colors), 4 configurable display modes, brightness adjustable across 0–255 levels. - Integrated web interface with dual-band 802.11 b/g/n WiFi, OTA-updatable firmware; powered by a 100W switching supply (5V/20A). --- ## Online apps and tools (free) - Broadcast Clock — online broadcast/radio clock: https://www.el-man.it/en/app/broadcast-clock.html - Timecode Calculator — with frame-rate handling: https://www.el-man.it/en/app/timecode-calculator.html - Audio Signal Generator — sweep, TTS: https://www.el-man.it/en/app/signal-generator.html - Talking Clock — multilingual: https://www.el-man.it/en/app/voiceclock.html - LTC Generator — free, with WAV export: https://www.el-man.it/en/app/ltc_generator_only.html - PTP Timing Calculator — IEEE 1588 message intervals, SMPTE ST 2059-2 and AES67 profile parameters, SM TLV dataset, TAI/UTC conversion, ST 2059-1 frame alignment: https://www.el-man.it/en/app/ptp-calculator.html - Genlock Timing Calculator — cable delay in lines and pixels, sync generator advance, black burst and tri-level timing, SD/HD/UHD format reference: https://www.el-man.it/en/app/genlock-calculator.html ## Resources - Broadcast Academy — training on NTP, LTC converters and TV synchronization: https://www.el-man.it/en/academy.html - Maker Corner — custom projects and innovative solutions: https://www.el-man.it/en/maker-corner.html - News: https://www.el-man.it/en/news.html - Magazine — broadcast, video and Pro AV news: https://www.el-man.it/en/magazine.html - About Us — company history since 1984: https://www.el-man.it/en/whoare.html ## Contact - Contact / request a quote: https://www.el-man.it/en/form.html - Italian site: https://www.el-man.it/it/ · Sitemap: https://www.el-man.it/sitemap.xml
