External Loudspeaker System; 3-Position Switch - Johannus Opus 5 User Manual

External Loudspeaker system

The organ can be extended with an external loudspeaker system, for example a pipe facade with
several speaker boxes behind it. At the back side (or kept internally) is an connector (octal
socket). With a special cable you connect the loudspeaker system to the instrument. In that case
there will be a 3-position switch on the instrument too.
The 8 pins of the octal socket are connected as follows:

3-position switch

This switch enables you to choose between loudspeakers in the organ and the external
loudspeakers.
The switch has the following positions:
Position A
The organ sound comes from the loudspeakers in the organ console and not from the external
loudspeakers.
Position AB
The organ sound comes from the loudspeakers in the organ console as well as from the external
loudspeakers. However, the sound from the loudspeakers in the organ console is softer than the
A-position.
Position B
The organ sound comes from the external speakers and not from the console
speakers.
