EXT. REV.
The connection EXTERN REVERB is specifically for the JOHANNUS external surround
acoustics device. This system, that works with 4 independent loudspeaker boxes in the room,
creates a realistic acoustical impression of a concert hall, church or cathedral. It is not
recommended to use this output for other purposes.
PHONES
This is the connection for a stereo headphone and suited for up to 2000 ohm.
Using a low impedance headphone (e.g. 8 ohm) may give a too loud a volume. This can be
regulated with the VOLUME control.
When using a headphone the organ loudspeakers will be automatically switched off. All
loudspeaker channels will be divided stereophonically through the two headphone channels.
