Wohler introduces 16-channel audio monitor
September 21, 2008
Wohler Technologies has introduced a new audio monitor based on the WohlerPlus modular platform. Developed to meet broadcasters' demand for a dedicated monitoring solution, the new AMP2-16MSDI provides instantaneous display for up to 16 channels of embedded audio within a single multirate HD/SD-SDI signal.
Built on a fully digital system architecture featuring multiple high-fidelity Class D amplifiers, the AMP2-16MSDI provides near-field monitoring for any mix of stereo and mono sources in a compact 2RU design. The unit includes demuxed outputs of eight AES pairs on unbalanced 75ohm BNC connectors and also provides a reclocked loop output of the SDI signal.
The AMP2-16MSDI features a high-resolution LCD display with colorful 210-segment high-resolution bar graph level meters. Colors and settings for scale and range are user-selectable along with several predefined scales and ballistics, including AES, BBC and Nordic. Each displayed meter set clearly indicates the phase for stereo sources prior to output on the speakers. The AMP2-16MSDI audio monitor also addresses key issues in DTV audio delivery, providing measurement of program loudness in adherence with ITU-1770/1771, which is displayed prominently on the unit's LCD status screen.
The AMP2-16MSDI is delivered with a default operating configuration but offers operators up to four user-definable presets that store and recall all parameters selected or adjusted by the user. All functions are also accessible via Ethernet with an optional PC-compatible application. The remote application can also display the meters on a large screen or projector.
