CONNECTION - The figure above illustrates the installation of the SENTINEL into a user’s facility. Measurements made with the SENTINEL are available for display anywhere on any web browser with access to the network – no special cabling or computer required. Several SENTINELs can be connected to signals throughout the user’s facilities and the results viewed and compared from any location at any time. Gone is the need to travel to any specific point in the signal chain just to check operation. Attention and, more importantly, travel is only required if and when a problems occur.

AUXILIARY INPUTS - The SENTINEL includes 6 auxiliary DC inputs with a measurement range of 0 to 2.55V. The SENTINEL also continuously monitors its own temperature, generally only slightly above that of the rack in which it is mounted. These voltages can be assigned user defined labels and, along with temperature readings, are saved in the logs and can be shown on the Display page. Alarms can occur when any of these fall outside user-set minimum and maximum values.

LOGGING - Levels, loudness, compatibility, metadata and all other measurements and errors are logged in an internal memory. With all channels in use and all error checking enabled, the memory can handle more than 24 hours of data. To archive this data a simple script may be executed on a networked PC to download the log file at the end of each operating period. These daily logs may then be stored indefinitely.

TIME STAMPS - The SENTINEL includes a Linear Time Code input which can connect to a facility-wide time code signal. It also includes a highly accurate real time clock/calendar which time stamps all measurements and errors. This allows precise identification of events in both program position and time, greatly assisting diagnostic efforts.

The Qualis Audio Sentinel offers dramatic improvements in operational efficiency and significant reductions in error rates. The operational efficiencies lower audio QC cost while reduced error rates yield higher customer satisfaction.
