Small Monitor ‘De-Embeds’ 3G/HD/SD-SDI Audio Signals

"As SDI infrastructure and facilities increasingly become the standard, it’s no longer necessary that every audio monitoring station be equipped to handle analog, AES, and optical signals along with SDI signals," said Don Bird, chief marketing officer at Wohler Technologies. "When audio and pictures in an edit suite, production suite, or mobile unit are handled via SDI, a dedicated, easy-to-use monitor like the AMP1-16M provides a highly functional, cost-effective solution."

He’s talking about his company’s new AMP1-16M dual-input SDI audio monitor for embedded audio in 3G/HD or SD-SDI streams, which will be featured in the company’s booth at the upcoming NAB show that starts April 15 in Las Vegas. The compact unit de-embeds and monitors any or all of the 16 audio channels in 3G/HD/SD-SDI signals, company literature says, “providing intuitive operation via adjustable volume and balance controls as well as clear display of levels and other critical information on bright 2.4-inch LED-backlit LCD displays.”

The monitor also offers instantaneous selection and summing of any SDI audio pairs; gain adjustment/trim on individual audio channels with the ability to assign channels to either or both outputs as well as select or deselect channel pairs; pass-through of both SDI inputs; and re-clocked output of the selected monitored SDI stream. A 1RU height and a depth of only 4.25 inches makes the monitor easy to install in a truck or small facility.

An Ethernet port on the AMP1-16M allows an engineer to reconfigure multiple units to “meet the needs of a specific show or production application, but also the requirements of the different operators working with the system.” Using the AMP1-16M’s PC-based software interface, techs can configure, download and store presets for multiple units from one central location.
