The clean, concentrated power of FM
Optimized FM concentrates
the power of the transmitted
signal inside the operating
channel, with minimal noise
and out of band signals.
The process starts with a
DSP-controlled limiter that
prevents distortion from loud
signal peaks as much as 30
dB above full modulation.
Audio is then sampled at 88.2
kHz and converted to a 24-bit
digital stream. The digital
audio is then analyzed and an
encoded signal is delivered to
the RF amplifier stage using a
patented algorithm.
The encoded signal is transmitted over a wide deviation
FM carrier and delivered to
the receiver. The DSP in the
receiver decodes the signal
and restores the original 24-bit
digital audio.
No compandor is applied to
the audio signal at the transmitter input, which preserves
the natural dynamics of the
sound, without distortion.
A fully optimized FM radio link
is used to deliver the signal to
the receiver. The power of the
RF signal is concentrated
within the channel, with minimal noise and out of band
spurious signals.
This is the best of digital
working the best of analog to
deliver world class audio
quality and reliability.
But measurements are not
everything. The real measure
is the smile on your face when
you listen to it for the first time.
