3 BAND AUDIO PROCESSOR: A BROADCAST
FANTASY MADE REAL
The mirage of perfect sound has eluded radio
since its first days. But now the fantasy
has been made real and given radio mastery
over the sound it creates - at a cost it
can afford.
MIRAGE FM is the result of this dream
come true - the embodiment of a broadcaster's
desires. The differentiated audio levels
are regulated and merged with extreme care.
The sound heard by the listener is perfect,
unique , fully calibrated and constantly
under control.
PERFECTION WITHIN GRASP
The battle for supremacy being waged between
radio stations hinges on the attainment
of better sound quality. Sound is the yardstick
that defines the quality of the broadcaster
making the Audio Processor a crucial factor.
The quest for perfection is a goal that
no radio station can afford to ignore.
AEV has listened to those who have said
that the search for excellence has brought
financial burdens beyond their means; it
has created Mirage FM , a Multiband Audio
Processor allowing each station to create
its own sound, in the tradition of AEV's
high technology background.
AUDIENCE BOOSTING FEATURES
Brilliant and full sound, maximum and constant
modulation. Mirage captures and boosts audience
figures.
AEV's Multiband Audio Processor will increase
listening figures. Radio captures audience
with quality and maintains it with an attractive
sound.
The fruit of AEV's technical knowhow, Mirage
FM's form and function are the result
of rigourous attention to the essentials.
Rugged and compact, it has been designed
to embody both excellence and affordability.
TOTAL CONTROL OF MODULATION
In FM transmission, the signal fed to the
transmitter must not, under any circumstances,
exceed a deviation of 75 KHz. High level
peaks, normally of short duration, do not
carry sound energy and produce over-modulation.
To limit these peaks, single band limiters
act over the entire audio spectrum and generally
attenuate the sound. Mirage FM divides
the signal into 3 frequency bands and controls
them separately, acting only on the band
in which the peaks are present. This is
performed without compromising sound density
and maintaining a full and constant modulation.
EXCITING SOUND
The adjustable functions of Mirage FM
allow the audio signal to be processed and
immediately adapted to the requirements
of the broadcaster. In this manner Mirage
FM can produce deep, powerful bass,
brilliant mid-range and clean, sharp treble.
The speaker's voice will be exalted and
the intelligibility of phone-ins will be
greatly improved. The sound of your radio
station will become warm and embracing or
aggressive and exciting, precisely as you
want it to sound - with full modulation,
constantly monitored and distortion-free.
DIGITAL STEREO ENCODER
The digital stereo encoder fitted to the
Mirage FM MPX as standard, demonstrates
just how advanced an audio processing system
can be. Beyond guaranteeing superb stereo
separation between channels, it ensures
maximum levels of modulation and total control
of spurious peaks generated by the low-pass
filter and pre-emphasis networks present
in external coders.
