The best location to install MIRAGE is as close as possible to the transmitter, in such a way
that the stereo encoder output can be routed to the transmitter.
The buffered outputs of the MIRAGE can drive an encoder via upto 10m of cable without
causing any appreciable degradation to the signal.
Should the output of the MIRAGE require a cable longer than the one that is recommended,
the best solution is to install an external encoder close to the exciter of the transmitter and
feed it directly from the Left and Right analog outputs of the MIRAGE.
To guarantee the maximum transmission quality, all apparatus used downstream of the
STUDIO should be carefully aligned and should conform to appropriate standards for
bandwidth, distortion, signal path delays and gain stability.
Such equipment should be re-calibrated at regular intervals; the signal source should be
lownoise, have as flat a frequency response as possible from 30 - 15,000 Hz and have a low
content of non-linear distortion.
