Sec. 1 The Xtreme audio processor
The Audio Xtreme II processor is a complete audio signal processing system for AM, FM and TV transmissions.
The sound quality defines the station’s image and professionalism. The importance of the AUDIO PROCESSOR is
therefore clear.
The wholly digital technology with which Xtreme II was built means that the results obtained can IN NO WAY BE
COMPARED with those of any other traditional processor.
The multi-band structure is the best way to process an audio signal; Xtreme II is based on five-band processing of the
audio signal, with a storage capacity equal to 82 different equalization curves, 64 of them editable.
Every curve has the facility for integral control of process parameters to give your station a competitive sound, with extra
power, continuity, presence and clarity, without “pumping” or other unnatural effects.
All of XtremeII’s adjustments and operational sequences are distinctly shown on ahigh resolution LCD graphic display
and are facilitated by a guided menu showing the enabled functions at every programming step.
The equalization and compression curve trends are shown on the display, which graphically reproduces the spectral
distribution of the processed signal over 5 bars.
Sec. 1-1 Full control of peak modulation
XtremeIIprovides full control of AM, FM andTVaudio signal transmission levels and can interfacewithany transmitter
habitually used in any part of the world.
Xtreme II performs a high-precision peak control, restricting over-modulation level to just 0.3 dB !
The Xtreme II audio processor dynamically controls the pre-boost level, it can never be heard to operate, and produces
a clear, open, brilliant sound which improves the original program.
Xtreme II’s audio processing circuits produce a signal which is pre-boosted with 50 µs or 75 µs curves and is controlled
precisely and absolutely in order to avoid over-modulation; the signal is then filtered to protect the pilot tone at 19 KHz.
If the 2-channel signal output by the processor is inserted in an external stereo encoder, we advise you not to place any
elementbetween the two appliances that could alterbandwidth and enlarge modulation peaks beyond averagemodulation
levels. Otherwise, modulation level must be reduced to control the highest peaks.
Low-pass filters, high-pass filters, transformers, distribution amplifiers, and long transmission lines, can all cause the
signal to alter. We advise you to by-pass any low-pass filter and pre-booster circuits present on normal stereo coders; we
should stress that these measures have already been adopted inside the processor.
Obviously the above criteria for optimal control of peak modulation levels can be satisfied more easily if the audio
processor uses the internal stereo encoder. In Xtreme, there are no circuit elements between the audio processor and the
internalstereoencoderthat could cause wave shape distortions. We therefore advise you to use Xtreme with its own built-
in encoder whenever feasible.

Sec. 1-2 Programmability
Xtreme II is supplied with 18 program-resident equalisation curves; they help the user understand the programming
process. The remaining 64 curves are at the user’s disposal.
For specific programming operations, see the appropriate paragraph.
All programming operations can easily be directly retrieved by the operator, by using the “Jog” knob or by using the
“Planning” programming at exactly specified times.
Sec. 1-3 Controllability
Xtreme II has a real-time clock enabling recall of presets at specified times (Planning).
Xtreme II has full remote control capability via an RS-232 / RS-422 serial port (for interfacing with a computer or
modem).
Optional management program.
Sec. 1-3 Input/output configurations
Xtreme II was designed to house the following simultaneously:
1. left/right analogue inputs and outputs
2. Standard AES EBU digital inputs and outputs
3. 2 composite stereo outputs (for FM version)
4. RDS input (if RDS coder option is not installed)
5. SCA input (for FM version)
6. RDS output (if RDS coder option is installed)
Sec. 1-4-1 Analogue inputs/outputs
The analogue inputs are installed on two XLR female connectors, located on the rear panel. The input is ≥10 KΩhigh
impedance, and the inputs accept signals up to +12dBu. The analogue outputs are provided with two XLR male
connectors, located on the rear panel. The outputs can pilot loads of ≥10 KΩ.

Sec. 2 Positioning and initial pre-set of Xtreme II
Sec. 2-1 Xtreme’s best position
Xtreme II’s best position is as close as possible to the transmitter, so that the stereo encoder output can be connected to
the transmitter via a route causing minimal variation to the wave shape of the MPX signal.
Xtreme II outputs can pilot a coder with cable length of up to 3 m before any appreciable degradation of the MPX signal
is noted.
If this is impossible, the best solution is either to: power up an external coder located close to the transmitter energiser via
Xtreme’sbase bandanalogueoutput, or to use the digitaloutputwith an essentially flat frequency responseplusa constant
wave train delay in the range 30 Hz to 15 KHz.
To ensure maximum transmission quality, all appliances downstream of the studio must be carefully aligned and must
satisfy the appropriate standards for wave width, distortion, wave train delay and gain stability.
These appliances must be re-checked at reasonable intervals.
It is therefore important that the sound source connected to Xtreme II has low noise at output, the flattest possible
frequency response and low distortion.
Sec. 2-2 At first power-up
Before powering up XtremeII, make sure that mains power matches the value shown on the rear of the power supply and
that the electric system to which Xtreme II is connected, is supplied with a good grounding system.
The display may be difficult to understand at power-up, therefore, set the contrast level (see the appropriate section)
.
Sec. 3 Input/Output connections
When connecting inputs/outputs, you are recommended to use a good quality, well shielded, soft cable.
Sec. 3-4 Remote control
Xtreme II can be remotely controlled via an RS-232 standard serial port – this enables you to control it via both PC and
modem.
A 15-pole connector is also available on the Xtreme II’s rear side to send on air 8 different presets simply by means of a
command of an external switch. For connection details, see section “Connections” at the end of the manual
Preset assignments occur by means of “TLC” menu.

Electronic Broadcast Equipment
Sec. 5-1 BRILLIANCE
Controls high frequencies and thus brilliance of the sound.
We recommend 3.0
Sec. 5-2 HF CLIPPING
Controls the timbre of high tones: either SOFT 0.0 or more cutting +6.0
We recommend 0.5
Sec. 5-3 PRESENCE
Controls medium frequencies whose range of values also includes voice signals.
We recommend 0.5
Sec. 5-4 MID BASS BOOST
Controls medium to low frequencies
We recommend 0.0
Sec. 5-5 LOW BASS BOOST
Controls low frequencies in two modes:
MODE A : Increases to obtain a peaking Bass
At full scale of MODE A there is automatic change-over to MODE B
MODE B : cancels mode A and increases a more muffled, softer bass.
Sec. 5-6 BASS MATCHING
Used to keep the Bass if Low Bass Boost is set high.
If low bass amplification is increased too much, sometimes the bass tends to go off its limit (it does not leave the 75KHz
modulation. The off limits bass effect is purely an acoustic effect ).
By using this control, high percentages of Low Bass Boost can be obtained, however, keeping the bass always under
control.
Bass Matching 0% = Free bass
Bass Matching 100% = Bass tied to medium frequency
We recommend 30%
Sec. 5-7 30Hz Hpf Filter
A filter which eliminates the “rumble” typical of turntables and feedback from speakers into the microphone.
We advise you to leave this ON

Electronic Broadcast Equipment
Pag. 20 Xtreme
Sec. 5-8 Voice Bass Boost
XtremeIIis able to recognise the voice from the rest of the program and, thanks to this control, it activates a pleasant full
bodied, thrusting effect that is great to listen to..
This control is fully transparent during a music programme and, in any event, does not create anything artificial, leaving
a clean sound (both voice and music).
We advise you to leave this ON
Sec. 5-9 Gate Threshold
This prevents Xtreme recuperating ground noise during silent pauses, because, by switching on the GATED indicator
light on the display, it locks out the bands preventing the bands from gaining ground noise.
We recommend -45dB
Sec. 5-10 AGC On Off
Activates the input pre-leveller, without which Xtreme could change the timbre according to level.
Always leave it ON
Sec. 5-11 AGC Drive
For piloting AGC.
Whenthemachine is aligned with respect to the mixer (see installationchapter),adjustthis control in order to “SQUASH”
the AGC bar to -10 -15 dB in the event of a fully modulated programme ( 0 dB ON MIXER )
Sec. 5-12 AGC Release
For fixing the speed at which the AGC follows the sound.
1 slower (for a very classic, stable, original sound)
20 fast (for a full, dense, rich sound)
We recommend 10 - 15 dB/sec
Sec. 5-13 Multi Band Drive
The higher is the level, the more the sound is compressed and therefore less dynamic. This causes a higher middle
modulation.
Too much compression can, in time, cause tiredness while listening.
Optimal compression is in the range of -5 to -15 dB
We advise you to set this control between 10 and 15
