DaySequerra M4.2R
HD Radio Tuner with Ethernet

M4.2R

Introducing the M4.2R. Think of it as an M4 on steroids. Like the original M4, the M4.2R gives you superb audio through its over-sampled D/A converter and Class-A biased audio outputs. With HD Radio stereo separation exceeding 90dB and THD+N under 0.5%, you won't just listen - you'll hear. Like its predecessor, the M4.2R stores 20 AM and 20 FM presets and tunes AM, FM and HD Radio Multicast channels HD-1 through HD-8. The digital audio output works full time, even when tuned to an analog station. And its benchmark sensitivity and superior IF rejection makes the M4.2R at home in extreme RF environments.
