Just in time for the NAB Show, is the Justin! Ba-da-bump!

Thank you, we’re playing here all week …

But seriously, the Justin 808 from Inovonics is catching the wave of HD Radio products at the show.

According to Inovonics, the Justin 808 is a time-alignment processor that brings analog FM and HD1 channels into sync, and automatically maintains sync, day-in and day-out. The manufacturer says that it eliminates the effects from top HD Radio problems, such as echo, stuttering, and even lost or repeated words, as receivers cross-fade between analog and digital reception.

The Justin 808 is placed in line with the AES digital audio feed for either the analog FM or the HD1 digital program. It then monitors the station’s off-air signal and utilizes correlation algorithms to sync the analog and digital programs with 23 microsecond (±1 sample) accuracy. The unit also corrects for program audio phase inversions between the formats, and can optionally trim the program audio level to match FM and HD loudness, based on true-RMS values.

The Justin 808 includes a Web interface with SNMP support. This allows remote control with any PC, tablet or smartphone Web browser. Signal loss and other alarms are dispatched as SMS text or email messages and actuate rear-panel tallies. The unit logs all errors and can generate a graphical display of timing correction over any specified period.
