Having time-alignment problems with your HD Radio? For the NAB Show DaySequerra is demonstrating its M4DDC Diversity Delay Control (shown). It’s a 1 RU, standalone AM-FM solution and runs the company’s proprietary TimeLock algorithm to automatically maintain time-alignment of the HD Radio MPS and HD-1 audio streams. Email alerts are dispatched directly from the M4DDC for loss of TimeLock, Level-Lock (optional), program audio, carrier or OFDM HD Radio Lock. There are five rear-panel alarm tallies.
DaySequerra is also showing the M4.2S, an analog AM/FM and HD Radio AM/FM tuner, that can monitor HD Radio diversity delay 24/7 with its proprietary TimeLock algorithm. According to the company, the unit receives the off-air broadcast and measures the timing difference between the MPS and HD-1 streams. Out-of-tolerance conditions can be reported via email or its built-in web server using any browser on a network. The M4.2S can be flash-updated using its Ethernet port and has four additional rear-panel alarm tallies.
Also on display is DaySequerra’s M2HDSP, an analog AM/FM modulation monitor can now monitor HD Radio diversity delay 24/7 with the proprietary TimeLock algorithm. It receives the off-air broadcast, and measures the timing difference between the MPS and HD-1 streams. Out-of-tolerance conditions can be reported via email and its built-in web server. It can be flash-updated and has four additional rear alarm tallies. Its web server displays a broadcast’s Artist Experience album art, station logo and advertisers’ branding.
