1 - Overview
1.1 Introduction
The audio processor is a complete audio signal processing system for AM, FM and TV broadcasts.
The multi-band structure is the best way to process an audio signal; In Mirage Dig Evolution, the audio
process it is based on the four-band transformation of the audio signal.
Each parameter configuration it is automatically checked for the audio effect
Finale can provide a feeling of general emphasis, greater power with continuity, presence and clarity,
without "pumping" or other unnatural effects that would result in "audio" effects that have nothing to do
with the original sound
1.2 Programming and use
All processor settings and all operating sequences are clearly displayed on a high resolution TFT color
display and are facilitated by a guided menu that shows the functions enabled for each programming
step, navigation in the menu, each parameter setting , Activation and programming in general, is
executed by means of the encode dial on the left of the TFT display
The resulting equalization and compression curves are displayed on the display, which
Graphically reproduces the spectral distribution of the processed signal on the various bands.
1.3 Flexi le configuration
The Mirage Dig Evolution audio processor is designed to meet all internationally-applicable security
standards, and can also be configured for analog and / or digital emissions and inputs.
Analog inputs are balanced high impedance active; The outputs are low-impedance and wide-band active
to ensure better transparency and a precise pulse response.
AES / EBU and optical digital inputs and outputs are available
The digital I/O follows the AES/ EBU standard, and runs at 32, 44.1, 48 and 96 kHz.
All inputs, outputs, and electrical connections are strictly anti-shake in accordance with the traditional
standards to ensure trouble-free installation.
1.4 Programma ility
The Processor comes with 8 equalization curves resident in the program, 4 of which are not editable:
FAST, VOICE, MEDIUM, LOW, and 4 other editable USER 1, USER 2, USER 3, USER 4, which help you
understand Of the programming process. The user can edit a custom curve, name it and store it; All
programming can be easily recalled directly by the operator from the list of stored curves; For specific
programming, refer to the paragraph in question.
1.5 Full control of peak modulation
Processor audio processing circuits produce a signal that is pre-emphasized by 50 µs or 75 µs curves
and is controlled in a precise and absolute way so as to avoid over-modulating phenomena; The
signal is then filtered to protect the pilot tone at 19 KHz.
If the processor's output audio signal (Analog or Digital) is inserted into an external stereo encoder,
it is advisable not to interpolate any other element between the two devices that could alter the
bandwidth and create a modulation peak magnification Medium modulation. Otherwise you will have
to reduce the modulation level to control the highest peaks
Frequency response errors and non-constant wavelength delay are typically introduced by equalizers, line
transformers, low-pass filters at 15 kHz, and pre-emphasized networks in stereo encoders.
It is therefore advisable, first of all, to "bypass" any low-pass and pre-emphasis filter circuits present in
normal stereo encoders; We would like to point out that these features are already present within the
processor.
Low pass filters, high pass filters, transformers, distribution amplifiers, and long transmission lines can all
cause an alteration of the signal with the above-mentioned consequences.
Obviously, the above-mentioned criteria for optimal control of peak modulation levels are met more easily
when the audio processor directly powers the internal stereo encoder. In the Mirage Dig Evo, there are

7
no circuit elements between the audio processor and the internal stereo encoder that can cause waveform
distortion. We therefore recommend using the Mirage with its built-in stereo encoder whenever it becomes
feasible.
1.6 Positioning
The best position of the processor is as good as possible to the transmitter, so that the stereo encoder
output can be connected to the transmitter over a short path, causing minimal variation in MPX signal
waveform.
The processor outputs can drive a coder with a cable length of up to 3 m without any appreciable
degradation of the MPX signal.
If this position is not possible, the best solution is to use digital audio signal transmission.
To ensure maximum transmission quality, all downstream equipment of the study must be carefully
aligned and meet the appropriate standards for wavelength, distortion, traction wave lags and
stability.
These devices must be re-checked at reasonable intervals.
It is therefore important that the audio source connected to the processor has low output noise, flat
frequency response and low distortion
The buffered outputs of Mirage Dig Evo can drive a coder with a cable length of up to 10 m. Before
any appreciable degradation of the MPX signal occurs.
1.7 First turn On
Before turning on the Mirage Dig Evo, make sure that the mains voltage is in accordance with the
voltage range indicated on the rear of the power supply and that the electrical system to which the
Processor is connected has a good grounding.
1.8 I/O audio configuration
The processor can operate and manage simultaneously:
1. Input Audio Signal selection ( Analog, AES/EBU, digital optical )
2. Balanced Analog output
3. Standard AES/EBU digital Audio output
4. Optical digital audio output
5. External MPX signal input / 19KHz synchronous output (MPX version)
6. composite MPX stereo output (MPX version)
7. RDS input - Radio Data System (MPX version)
8. SCA input (MPX version)

3 AUDIO Input & Output
3.1 Connection ca les
For input / output connections it is recommended to always use a good quality soft cable with good
shielding.
It is also necessary to check the correct functioning of the earthing system and that in the audio
connections between the GROUND and CHASSIS GROUND devices they are separated to avoid annoying
buzzing.
3.2 Analog Input/Output
The analog XLR input are electronically balanced with input 10 KΩ impedance.
The male XLR analog outputs are active with 47 Ω impedance.
The output range varies from -12 dBm to +12 dBm with a 1 dB step.
The level control of the analog inputs and outputs is implemented via software on the ANALOG INPUT and
ANALOG OUTPUT menus.
3.3 Digital Input AES/EBU
The AES / EBU digital input on female XLR can vary from -12 dBm to +12 dBm in 1 dB steps.
The input level control is implemented via software on the DIGITAL AES / EBU INPUT and DIGITAL
OUTPUT menus.
3.4 Digital Optical Input
The optical digital input is connected to the dedicated fiber optic connector
The input signal range varies from -12 dBm to +12 dBm in 1 dB steps.
The input level control is implemented via software on the DIGITAL OPTICAL INPUT menus.
3.5 Digital Outputs
The AES/EBU digital output is supplied on a male XLR connector, the optical digital input is connected to
the dedicated fiber optic connector.
The output range varies from -12 dBm to +12 dBm with a 1 dB step.
The level control of the digital outputs is implemented via software on the DIGITAL OUTPUT menus.
The selection of the sample rate of the digital signal is realized via software on the DIGITAL OUTPUT menus.
The value of the output level and of the digital signal network sample is unique for the AES/EBU signal and
for the optical signal.
4 Operation
4.1 Introduction to processing
In any sound source it is possible to define the mean value and the peak value.
In the mean value it contains much of the power and is therefore the most significant part of the
signal compared to the peak value that has contributions in terms of extremely low power.
Unfortunately, however, in the FM transmission, the maximum deviation of 75 KHz is determined by
the peak value; So you are forced to work with a low level level producing a non-incisive sound level.
To increase the sound level, reduce the peak-to-medium ratio; If the peaks are reduced, the average
level can be increased within the permissible modulation limits.
These operations can be achieved with signal limitation and expansion processes.
Mirage Dig Evo performs this processing on 4 different bands using ad ustable threshold compression
circuits.
Clipping is a more decisive control applied to that part of the signal that can not be compressed; This
operation is always necessary to ensure maximum deviation of 75 KHz. Cutting does not produce
audible side effects if it is carried out in moderation, in reverse, if it is used excessively, it may give
rise to more or less annoying distortion.
A compression level that exceeds -16 dB (eg -18, - 20 etc.) continuously indicates a probable error
setting of control parameters

5Page PROCESS
5.1 1th Section
In this section, all the audio process parameters are displayed to customize the configuration curve
that is applied to the audio signal.
Sound quality defines the image and professionalism of the broadcaster, so it becomes apparent the
importance of the AUDIO PROCESSOR.
Multiband Structure is the best way to process audio signal, Mirage Dig Evo is based on the process of
audio signal in multiband mode.
Each curve has the ability to have full control of the process parameters so as to give your issuer a
competitive sound with greater strength, continuity, presence and clarity without pumping or other
unnatural effects.

lower edge of the audio band.
By positioning the cursor on the box, you activate the mode modification by pressing the knob, after
selecting the desired mode (ON / OFF), the additional pressure sets the value indicated in the box.
• ENHANCER
With Enhancer, you can increase the spatial image of the stereo sound. With active Enhacer function
will increase the feeling of Loudness, with greater depth and spatiality of the sound, as well as a high
dynamic of the sound itself. The Enhancer function allows a similar effect to a "wide" separation
between left and right channels. This effect is achieved by adding a portion of the other to each
channel, but in a reverse phase. By modifying this, the L-R and L + R ratio produces a more
stereophonic sound, creating a very strong acoustic effect, especially on the audio details.
Includes activating / deactivating the ENHANCER function. By placing the cursor on the box, you
activate the mode change by pressing the knob, after selecting the desired mode (ON / OFF), the
