Wohler iAM-12G-SDI 12G-SDI Video and Audio Monitor
WOH-IAM-12G-SDI
The Wohler iAM-12G-SDI is the definitive multi-channel audio/video monitor for 4K UHD environments, housed in a 2RU format. It is designed for production and Broadcast, offering dual 12G-SDI inputs, compatible with 3G/HD/SD-SDI standards.
Its interface features 2x 4.3" LCD touch screens on the front panel, allowing simultaneous video display and monitoring of up to 16 embedded audio channels. It includes advanced Loudness metering (ITU/EBU) and high-resolution level meters, essential for audio compliance.
The acoustic section provides clear and precise audio monitoring via high-performance speakers. Its key strength is its future flexibility, provided by four bays that allow the optional integration of interfaces such as SMPTE 2110, AES67, Dante, or Dolby Atmos/E decoding modules, ensuring the unit adapts to any evolving infrastructure.



Wohler iAM-12G-SDI Reference Multi-Channel Audio/Video Monitor (2 RU)
The Wohler iAM-12G-SDI is positioned as the standard for audio and video monitoring in critical environments for Broadcast and post-production applications operating with signals up to 4K UHD. This robust Wohler device, in a 2-rack unit format, addresses the need for fast and reliable signal inspection (Confidence Monitoring) in a world of increasing multi-channel complexity and high bit rates. Its defining feature is the inclusion of two 12G-SDI inputs, which simplifies the infrastructure by handling 4K workflows without relying on multiple cables or external conversion, while maintaining full compatibility with 3G, HD, and SD-SDI.
The user interface is designed for immediacy, featuring a dual 4.3-inch LCD touchscreen configuration on the front panel: one dedicated to video image display and the other for measurement graphics, menus, and level bars. This allows the operator to visually monitor the video signal and, simultaneously, have a comprehensive view of the 16 embedded audio channels with peak and VU meters, as well as precise Loudness measurement (compliant with ITU and EBU standards). Wohler's acoustical section, recognized in the industry, offers superior clarity through powerful, full-range internal speakers.
What truly sets the iAM-12G-SDI apart is its future adaptability: its four bays for the insertion of optional modules allow for instant modular expansion. By adding the appropriate hardware modules, the unit can be transformed to decode Dolby E/D/D+, integrate into SMPTE 2110 or AES67 networks, or handle MADI and Dante I/O, making this monitor a scalable and durable solution for any technological transition. Control and configuration are simple thanks to its integrated web control interface and the possibility of updating via USB, ensuring that technical personnel always maintain full control of the signal flow.
