Introduction
The DaySequerra M2 HD Radio
quality modulation monitor available with built-in multicast capability. The M2 has been designed as the
benchmark in sensitivity (< 5.0dBf in FM) and reliability, and at the same time delivers the highest
quality, accurate monitoring of existing analog and HD Radio
<.005% with stereo separation >90dB for HD Radio
The DaySequerra M2’s ultra low noise RF front-end with built-in preselector and double-balanced
mixer, low-jitter DAC and Class-A biased audio outputs provide the highest fidelity reception and
demodulation of HD Radio
and SPS multicast signals.
Its robust, modular architecture ensures that the M2 will never become obsolete. The rugged M2
chassis houses dedicated hardware RF, audio and power supply modules that, along with firmware
updates via flash programmable memory, completely anticipates the growth of new HD Radio
services and programming. This design approach along with our product update program ensures that
a broadcaster’s investment in a DaySequerra product will continue to pay off well into the future.
Please read this manual thoroughly before operating your M2.
