daysequerra M4.2Si

Introducing the M4.2Si. DaySequerra’s new M4.2Si is the most powerful analog AM/FM and HD Radio® AM/FM tuner available today, and it’s an incredibly cost-effective solution.

DaySequerra’s new M4.2Si AM-FM Digital Radio Receiver is the most capable next-generation HD
Radio™ platform available today.
With the M4.2Si you can monitor audio and data from your analog and HD Radio broadcasts including
FM multicast channels HD-2 through HD-8. The M4.2Si has no AUTO-Blend function so it stays locked
to the stream you’ve selected even if the broadcast or your AC power is interrupted. Hear your HD
Radio time-alignment using the M4.2Si built-in Split-Mode. With the optional TimeLock™ Monitor, the
M4.2Si will even send an email if your MPS and HD-1 streams are out of time-alignment. The Remote
Dashboard webserver simplifies your under 3-minute setup and provides total remote control of the
M4.2Si using any browser on your Ethernet network. Plug and Play
