Prestige
It is important to underline that, in Prestige 100, 80, 70 and 60, the system automatically adapts the
channelling to the number of speakers connected. Below is an example with a voice channelled
using a “Wedge” wind-chest layout.

SHORT INTRODUCTION TO THE WIND-CHESTS OF PIPE ORGANS
The wind-chest is a box in which the air from a bellows is distributed. The bellows may be operated
by hand or an electric motor, and keeps the air pressurised and ensures it is uniformly distributed
through the pipes.
Normally, each manual has its own wind-chest which contains the pipes. However, there are various
types of wind-chest, which may contain a single register or have a cascade arrangement with an
organ valve (a box full of air filled by the bellows) with the branches leading off to all the registers
for each note.
The following is a short description of the wind-chests which the Prestige organ simulates:
-
Wedge
In this configuration, the tallest, broadest pipes are located in the centre,
so the voice’s lowest notes are played by the most central speakers.
As the pitch rises the signal is gradually distributed further and further
to the outside, in alternation; in other words, C will sound on the right
and C# on the left.
- Chromatic
This configuration is the opposite of the previous one; in this mode, the
tallest, broadest pipes are on the outside, so the lowest notes are played
on the outermost speakers, again in alternation. As the pitch rises the
notes are played closer and closer to the centre.
In models Prestige 40 and 50 you have to inform the organ about the number of the used outputs
through the item
in the display following described in this chapter.
