Wohler Technologies Inc., a producer of video, audio, captioning and loudness systems management and monitoring solutions, unveils the AMP1-MADIe, an in-rack portable multichannel audio digital interface (MADI) mixer with Ethernet control and configuration.
The AMP1-MADIe can be connected in series with a 56-channel or 64-channel MADI stream for individual volume adjustment, mixing and audible monitoring of any eight selected MADI channels at once, Wohler says. The AMP1-MADIe can provide functionality that is equivalent to a MADI audio “hot mic” mixer, and can simplify rapid selection and monitoring of MADI signals in fast-paced live-to-air production environments, the company says.
To support fast configuration and use of multiple distributed units within a MADI network, Wohler has outfitted AMP1-MADIe with an Ethernet connection and offers a free, downloadable software graphical user interface (GUI) so multiple units can be controlled and configured from a single PC workstation, the firm says. Operators can also store and retrieve their own system configurations via a front-panel universal serial bus (USB) connector, Wohler says.
“Initially engineered for large broadcast facilities looking to economize by routing audio signals over MADI, the AMP1-MADIe serves as a perfect solution for any application that requires a simple, compact system for monitoring MADI-delivered audio,” says Don Bird, Wohler’s chief marketing officer. An added benefit is the mixer’s ability to convert between optical and Bayonet Neill-Concelman (BNC) connector, he said.
The AMP1-MADIe provides a clear, light-emitting diode (LED)-backlit liquid crystal display (LCD) display that shows simultaneous metering and monitoring of any eight user-selected channels, with instant access to eight stored configurations of any eight channels for easy navigation among all 64 channels in a MADI stream, Wohler says.
The mixer is packaged in a compact four-inch deep, one-RU chassis with level meters, master volume, and channel volume, offering quick muting of selected channels as well as menu access, which can be enabled or disabled via external software control, the company says.
Also included on the front panel are balance control, monitor channel select, channel assignment and preset select buttons, built-in speakers, USB port and headphone jack. Rear panel connectors include both optical and BNC inputs reclocked to optical and BNC outputs, Ethernet connection, stereo left/right analog outputs, a mono mix on XLR and built-in universal power supply.
