PRAELUDIUM III - PRAELUDIUM IV/E - User's Manual
INTRODUCTION
The Transposer is particularly useful when accompanying for voices or other instruments. The two transposer led buttons
that control this function are placed next to the Programming Section and are marked with the symbols # and b.
It is possible to vary the pitch of the music by 6 SEMITONES BELOW and by 6 SEMITONES ABOVE standard pitch.
The position of the Transposer will appear on the display only when it differs from normal: i.e. Transp. = +3
To erase rapidly the command, press the two buttons simultaneously.
In TUTTI and CRESCENDO (see note 3) the organist is free to programme his own modifications to the Pedal stops, when
the Automatic Pedal is inserted. To do so, carry out all the operations already described in the paragraphs "Programmability
of the Presets" and "Programmability of Crescendo"
with the AUTOMATIC PEDAL INSERTED.

NOTE 2:
Before every performance, when the Transposer is not required, make sure that it is in the normal position.
• NOTE 3: only for organs supplied with it
• NOTE 1:
In addition to the automatic Pedal function, it is also possible to select PEDAL to GREAT for a monophonic coupler of the
Great and Pedal stops. See at page 32 (Utilities).
For this useful device the reversible thumb piston A.P. is located below Manual I. The relative LED is located on the left of
the display). With Couplers I-PED and II-PED, this device engages only the Coupler corresponding to the Manual which is
played, excluding the other. If the Automatic Pedal is drawn together with TUTTI and CRESCENDO (see note 3), the stop
configuration on the Pedal is immediately adapted to the Manual being used.

BALANCES AND SWELL PEDALS
PRAELUDIUM III is equipped with volume controls for each of the sound sections:
1 GREAT VOLUME Slider control is placed next to the Programming Section.
2 PEDAL VOLUME Slider control is placed next to the Programming Section.
3 SWELL balanced pedal Is placed above the pedalboard.
Once the correct levels of Great and Pedal have been achieved, in relation to balance and environmental acoustics,
there should be no need to make frequent changes later. The swell pedal continuously changes the volume of the Swell
section, thus allowing any dynamic effect. The swell balanced pedal also modifies the timbre of the stops, analogous to
that which occurs in a pipe organ with the closure of the swell shutters.
