Page 4: Quick Start - Creating A New Preset
NOTE: value ranges shown in the WIZARD window are tailored on the processing Preset being modified and do not represent any ‘absolute’ limit of the Falcon 50 FM processing. Enter the EQUALIZATION block (EQ), and modify the filter parameters first and then consider each filter effect by turning it on and off from the relevant function. -

QUICK START – CREATING A NEW PRESET E N G If You are able to detect a specific sound component (f.i. a specific instrument or frequency) giving bad results on the final output, try to identify the band or the bands involved and try to reduce their LIMITER Thresholds. -
Page 6: How To Create An Itu-B412 Compliant Preset From A Not Compatible One
QUICK START – CREATING A NEW PRESET E N G 2.3 HOW TO CREATE AN ITU-B412 COMPLIANT PRESET FROM A NOT COMPATIBLE ONE. Factory Presets ranging from 40 to 49 have been designed to meet ITU-B412 specifications. Thus, for an ITU-compliant broadcasting, You just need to load one of the ITU Presets (which are directly derived from the most common not-ITU ones) and turn the MPX POWER CONTROL in the MPX SETUP block on. -
Page 7: How To Change The Preset On Air
HOW TO CHANGE THE PRESET ON AIR E N G 3 HOW TO CHANGE THE PRESET ON AIR The processor has 100 curves: the factory presets (PR) are stored in positions 00 through 49, while positions 50 to 99 may be set by the operator. Before creating a new custom curve, we recommend that you carefully evaluate the factory presets, all of which are suitable for immediate on-air use given their average content of the various signal components. -
Page 8: Saving A New Preset
SAVING A NEW PRESET E N G 4 SAVING A NEW PRESET As preferred way to create a new Preset, it is advisable to pick up one of the existing one (either Factory done or user set) and alter it in order to get the sound You want. To pick up one of existing presets, refer to the previous chapter. -

5.2 IMPORTING PRESETS, GENERAL CONFIG. OR BOTH The Falcon 50 FM control software contains special tools to selectively import from a file a single custom preset, all user presets, a general equipment configuration/status (that is: input setting, output settings, pilot level, passwords, etc) or either the latter ones (all Presets + equipment Status). -
Page 11: Agc Operation
The AGC speed value is expressed in dB/sec – i.e. the number of dB amplified or attenuated in one second. The Falcon 50 FM allows You to set two different working speeds for the AGC main operation: the Attack speed and the Release speed, where the first one is normally significantly higher than the second one. High AGC Speed values obviously make it possible to quickly recover strong level differences, but they can also lead to unpleasant ‘pumping’... -

AGC OPERATION E N G When the AGC level is getting close to its internal reference level when releasing, the AGC will enter a so called WORK ZONE, where the AGC speed is reduced to the WZ Rel value stated in the AGC WINDOWS menu. -

AGC OPERATION E N G 6.4 SETTING IDLE COMP, IDLE SPEED AND GATE THRESHOLD PARAMETERS The two parameters IDLE Comp and IDLESpeed set the behaviour of AGC stage when the input signal is ‘silent’ or it falls under the Gate Threshold (see GateThr parameter). The Idle Comp sets the Compression rate the AGC will reach when no signal is provided at the input. - Page 14 THE PRESET LIST E N G 7 THE PRESET LIST N° NAME SCOPE DENSITY DEFINITION Rock (default) General Purpose High Adult Contemp General Purpose Very High Hot AC General Purpose Purist General Purpose High Soft AC General Purpose Wide Effect Effect Evaluation Mid-High Classical 1...

If you don't, write down the settings for each parameter. 7.3.2 RESET PROCEDURE REMOVE POWER from the Falcon 50 FM by disconnecting the AC power cord. Disconnect all other cables to make access convenient. REMOVE the TOP COVER from the unit by removing the phillips screws around the periphery of the cover. - Page 18 APPENDIX A E N G Reconnect the AC power cord to the rear of the unit. Switch the equipment On set the jumper JP1 to its LEFT (external) position: as soon as the Jumper will be set, the three front LEDs OPERATE, PC-LINK and ALARM will light firmly Remove and set again the Jumper in its Left position quickly: the OPERATE LED will turn Off Now, remove and quickly set again the Jumper in its Left position: the PC-LINK LED will also turn Off...
