Each singer has two microphones. They are asked to use one of them at a time.
The changes between the microphones are often marked with arrows from one
numbered circle to another, e.g.:
In such cases the change should be as smooth and gradual as possible.
When the change is indicated without an arrow, the singer just changes from
one microphone to another at the most convenient moment.
Of the two microphones, that each singer uses, the first
( ??? ) is considered to be
the main microphone. A slight basic reverberation (depending of the natural
liveliness of the hall) should be set. This reverberation is not marked in
Separately from this reverb, which will not be modified during the piece,
five different effects are sent, often individually, to these microphones.
The symbols for the effects are:
D for delay
ER for early reflections
H for harmonizer
G for gate reverb
F for flanger
See further for the settings of the parameters of these effects.

The reverberation effect used in the second microphone is a program in which
the reverberation time is changed constantly by the amplitude of the input
signal. The general idea here is, the quieter the sound, the longer the
reverb. The effect will start with the mezzo soprano voice in the second bar
and run through the piece. Normally it does not need to be touched during the
The amplified voices should blend well with this reverberation effect but
nevertheless remain slightly in the foreground.
