AHLBORN - HYMNUS IV
INTERNAL AMPLIFICATION
HYMNUS IV is supplied with internal amplification specially studied to enhance the tonal resources
and vast sound channelling possibilities.
The presence of two small diffusers (Top Tweeters) pointing upwards permits an improved
expansion of the acoustic sounds in the environment, offering the organist maximum sound
definition, such as could be obtained by playing, for example, in the vicinity of the pipes.
By means of the remote control (Interactive Programmer) it is possible to choose two special effects
that broaden the sound front (Panoramic 1 and 2), as well as all the normal perspective sound
configurations (central peak, wing, lateral wing etc.), or else the complete exclusion of the “Top
Tweeters”, if required. Refer to the INTERACTIVE PROGRAMMER Owner's manual, SECTION
C/WINDCHEST LAYOUT, page 26.
Following the description relating to the 10 types of sound channelling, the section HOW TO
OPERATE should be modified as follows:
A) SECTION CHANNELLING.
HOW TO OPERATE
1) Press for approx. 3 seconds the WINDCHEST LAYOUT button: the display will show the
following information:
CHEST LAYOUT
Panoramic = off
(flashing)
2) Press the
§
DECR. or
©
INCR. buttons to select the section which requires the sound
channelling.
The sections will appear in the following order:
SWELL
GREAT
PEDAL FLUES
3) Press ENTER: the values or the configurations of the left or right channels (see previous
indications) will flash.
4) Press the
§
DECR. or
©
INCR. buttons to select the required value.
5) Press the EXIT button once to proceed with the adjustment of another section, repeating the
operations at points 2-3-4.
Or: press the EXIT buttons twice to escape from the WINDCHEST LAYOUT control.
NB: the free selection of the section channelling is possible only when Panoramic = off.
B) USE OF THE “PANORAMIC 1 & 2” CONFIGURATION
These two positions create the effect of widening the general sound front within the instrument's
internal amplification.
Note that the position “Panoramic 1” retains the left/right (C /C sharp) sound channelling.
