Introducing the M4.2Si TimeLock. DaySequerra's M4.2Si, the most powerful analog AM/FM and HD Radio® AM/FM tuner available today, can now monitor your HD Radio Diversity Delay 24/7 with its proprietary TimeLock algorithm.

The M4.2Si receives the off-air broadcast, measures the timing difference between the MPS and HD-1 streams. Out-of-tolerance conditions can be reported via email and via its built-in webserver using any browser on your network. The M4.2Si can be flash-updated using its Ethernet port and has 4 additional rear panel alarm tallies.

  • Proprietary TimeLock™ Algorithm - Measures HD Radio Diversity Delay time alignment of the HD Radio MPS and HD-1 audio streams with accuracy to one audio sample, includes TimeLock rear panel alarm tally and email alert.
  • Robust 24/7 performance -stays locked to AM-FM analog, HD-1 or selected multicast stream during power or I2E interruptions; does not automatically revert to analog!
  • Analog AM-FM plus HD Radio - Complete monitoring of HD Radio AM/FM broadcasts including FM multicast channels HD-2 through HD-8: user-selectable tuning steps and analog FM 50/75 µSec de-emphasis.
  • Bright graphic LCD - provides front panel display of all RBDS and HD Radio PAD/SIS, along with network and alarm conditions; audio level, digital audio quality and carrier quality indications.
  • Artist Experience - monitor your broadcast's album art, station logo and advertiser branding.
  • Email Alerts - Get an email alert direct from your M4.2Si TimeLock for loss of TimeLock, Program Audio, Carrier, or OFDM HD Radio Lock; 5 rear panel alarm tallies.
