Switch Organ/Aux In
This switch allows you to switch to the device you want to add the acoustic surround sound to.
When the switch is not pushed-in the organ is connected to the acoustic system.
When the switch is pushed-in the second device that has been connected (e.g. a Hifi stereo
equipment) is connected to the acoustic system.
LED indicator
The LED indicates the level of the input signal.
The LED lights up in green with an average signal level.
The LED lights up in red when the signal level exceeds a certain level. This will cause so a
distorsion to occur.
Adjusting the input signal level
With the rotary control INPUT the input signal level can be adjusted.
This level must be adjusted so that the LED will light up in green only when a signal is received.
The rotary control will adjust both the right as well as the left input signal at the same time.
Adjusting proportions direct signal/acoustic signal
With the rotary control MIX you can balance the direct (dry) signal and the reverb (wet) signal
that will come from the acoustic system’s loudspeakers.
The direct signal is the received signal that is amplified and reproduced without adding a reverb.
The indirect signal is the received signal that has been processed into a reverb signal.
By turning the MIX rotary control to the left there will be more direct signal and less reverb signal
coming from the loudspeakers. When the MIX control is completely turned to the left only direct
signal wil be audible.
By turning the MIX rotary control to the right there will be more reverb signal and less direct
signal coming from the loudspeakers. When the MIX control is completely turned to the right
only reverb signal wil be audible.
