Electronic Broadcast Equipment 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.
Electronic Broadcast Equipment 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.
Electronic Broadcast Equipment Sec. 1-4-4 RDS input (optional) The RDS input is active in the FM version, if the RDS internal coder is not installed. It is provided with a BNC connector, located on the rear panel, with 10 KΩ impedance. Accepted levels range between 0 and -14dB. Sec. 1-4-5 SCA input A non-balanced BNC connector, for use with the SCA signal, is also available on the input. It can accept any type of ≥ 23 KHz subcarrier. The subcarrier is mixed with MPX signals.
Electronic Broadcast Equipment 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.
Electronic Broadcast Equipment Sec. 4 Xtreme start-up To align Xtreme II with your system as the first operation, we advise you to recall one of the configurations preset inside Xtreme II. Starting from the initial menu “Home”, press Jog and enter the menu “Process”. By pressing Jog, you can select “Recall Preset”, then choose one of the 18 preset curves Pag.
Electronic Broadcast Equipment At the end of the selection, return to Home menu by means of the “Back” option. Sec. 4-1 Pre-enphasis If you wish to use Xtreme II’s 2-channel output, you must disable the pre-enphasis, or in any event, use the transmitter’s linear inputs. This measure is essential in all cases, even if telephone lines are used up to the transmitter to transfer the signal. To enable Xtreme II pre-enphasis on the Right and Left outputs, carry out the following set-up.
Electronic Broadcast Equipment Then select Pre-emphasis and choose Change option. By means of the Jog you can scroll the available options: OFF, 50µS (European standard) and 75µS (USA standard). At the end of the selection, return to Home initial menu. Sec. 4-2 Adjusting the input level Play a piece of music ( CD ) with good dynamics and a rich sound. Adjust the mixer to obtain 0dB indication on the instruments.
Electronic Broadcast Equipment Sec. 4-3 Adjusting MPX coder parameters May we remind you again that any other pre-enphasis on your transmission chain must be disabled as it is generated by Xtreme II. Press Jog and select Encoder.
Electronic Broadcast Equipment Select the parameter to be changed and carry out the correct set-up by means of the Jog. If you are varying a parameter, but you wish to return to the previously set value, a “X” is shown on the right of the bargraph which not only stresses the control used, but it also goes off if the set value corresponds to the parameter value before any change. Sec. 4-4 System menu options System menu enables following set-up Pag.

When the arrow on the right of the bar disappears, the set-up carried out will be On Air. Sec. 5 Edit Preset menu Through the selection of Process menu, recall the option Edit Preset.
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.
Electronic Broadcast Equipment Sec. 5-8 Voice Bass Boost Xtreme II is 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.
Electronic Broadcast Equipment Sec. 5-14 Multi Band Release The moving speed of the 5 bars Slow (a full, stable, but very peaceful sound) Medium-Slow (a full sound suitable for general peaceful music) Medium-Fast (a full sound suitable for all types of radio format) Fast (a very lively, full sound, at range limit, suitable for radio rock – super hits) We recommend Medium-Fast Sec. 5-15 Multi Band Clip This controls a circuit which clips the audio signal without introducing any distortion. -4.
Electronic Broadcast Equipment Sec. 6 System Update To update your Xtreme II, you need the following material: 1- Pc with a free serial port 2- Software to load the new updatings for Xtreme II 3- Updating files (updating file + file with Updating instructions). If the above material is available, you can go on, otherwise you can contact the customer service. Connect the serial cable between Xtreme II and PC. By means of the RS 232 menu select the option XTREME.
