ADVANCED TECHNOLOGY FOR EXCELLENT RESULTS
Starlight 2 is a digital stereo encoder
for broadcast applications that has been designed
using highly innovative technology.
The result is the most advanced that a stereo
broadcasting system can offer, with an exceptional
array of features.
Besides guaranteeing excellent stereo separation
between channels, AEV's
Digital Stereo Encoder ensures a transparency
of sound never before reached, whilst maintaining
exceptional stability.
Starlight 2 can be installed instantly
and can be matched perfectly to any transmission
system without calibration.
STEREO CODER
It employs a digital modulator at a sampling rate
of 32x that generates frequencies at 19 and 38
KHz for respectively the pilot and subcarrier.
The employment of a great quantity of "samples"
offers a better spectrum clarity and mantains
the MPX signal constant. The stereo separation
levels are constantly over 65 dB.
COMPOSITE PROCESSOR:
In order to limit the overshoots, Stargate uses
"DSP-Filtering" system composed with a couple
of digital low-pass filters, an exclusive AEV
"hybrid", that allows not only a phase linear
design, but also dynamically flat responses together
with 115 dB/oct slope.
The qualities of this system grant perfect
spectrum clarity up to 15 KHz.
At the modulator output another "Safety Clipping"
stage removes the remaining overshoots produced
by the filters. |
