Wohler Technologies is extending its ground breaking iAM Series of products with a new multi-channel audio and 12G video monitor that accepts 2 x 12G/3G/HD/SD-SDI signals over BNC.  4 SFP cages allow for a variety of additional monitoring options, including 2110, 2022-6, as well as additional SDI inputs in a variety of combinations listed in the table below.  Our Dolby® ATMOS option allows decoding of Dolby® Atmos content, along with the familiar Dolby® D, Dolby® D+, and Dolby® E content.

Flexible. Adaptable. Future Proof.

iAM-12G-SDI is designed to be easy to operate, yet powerful enough to provide high quality, accessible and easy to use monitoring of the newest signals (12G, 2110, 2022-6) within a compact form factor. Incorporating the latest technology,

Physical and touch screen front panel controls duplicate previous mature design philosophies of shipping iAM Series units. With both front mounting speakers and sub-woofers, the iAM-12G-SDI provides the powerful sound output and audio reproduction that Wohler is well known for.

A front mounting USB port is available for simple software updates. Multiple units on the same network can be updated, monitored and controlled via a browser-based user interface that supports fast configuration with authentication that protects critical configurations from unauthorized alteration.

Added in 2021 “Output Routing allows channels to be either routed, or combined and routed, in custom ways to various destination outputs. It may be applied to signals being monitored directly from the front panel, or by using presets that have been created to apply the Output Routing.

Dolby® ATMOS option allows decoding of Dolby D, Dolby D+, Dolby E and Dolby Atmos for the IAM-12G-SDI

Dolby Atmos creates an amazing experience over speakers and over headphones, with breathtaking, moving audio that flows above and around you. You’ll feel like you’re inside the action as sound comes alive with richness and depth, and seems to move in three-dimensional space. Immersive and emotive, Dolby Atmos is sound you can feel — sound that creates a powerfully moving entertainment experience.  Wohler’s Dolby Atmos option allows broadcasters to confidence monitor the Dolby Atmos signal on Wohler speakers and headphone output, view meters, access Wohler’s proprietary Dolby Zoom functionality, review related metadata, and route the audio externally to SDI or analog outputs on the rear panel.
