SPL Channel One Channel Strip - Manual (Page 12)

A further specialty is the integrated auto-threshold-function which makes
processing independent of the input level. Even when the speaker or singer
does not maintain a constant distance to the microphone, processing is
retained at the pre-set S-reduction value. Conventional systems are depen-
dent on the input level and work more intensively as the distance to the
microphone is reduced.
The insert button activates any attachments of external equipments for
effects, equalizing or compression that are connected to the Insert
Send/Return loop on the rear of the Channel One. This binds them into the
signal chain thereby enhancing the processing capabilities ad infinitum.
The Insert point is located between the De-Esser and compressor. This
allows the ability to use the pre-amplifier stage/de-esser combination of the
Channel One separately from the compressor/EQ combination which,
because in this manner the Channel One can be used as 2 independent
units, broadens the range of uses enormously.
As long as units are not connected to the insert loop the signal flow is not
interrupted, even when the Insert button is pressed. The most flexible
method of use with the balanced designed insert sockets is to be achieved
by connection to a patch bay.
On
The On button activates the Compressor/Limiter/Noise Gate module. At the
same time the Gain Reduction display shows the processing intensity (see
section ”Gain Reduction” on page 13).
Usually the signal flow follows the design of the Channel One and for this
reason the input signal normally arises from the De-Esser or, when activated,
from the Insert. However with the Pre Comp. switch function of the Equalizer
module the Compressor/Limiter can be switched behind the Equalizer. This
allows it to be used either as an final compressor or limiter. (Further informa-
tion in the section ”Pre Comp.” on page 15).
