INSERT
The insert button activates any attachments of external equipment for effects, such as delay
or reverb, 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 to use the pre-
amplifier stage/de-esser combination of the Channel One separately from the compressor/
EQ combination. This broadens the range of uses enormously, because in this manner the
Channel One can be used as two independent units.
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 REDUCT. display shows the processing intensity (see “GAIN REDUCT.” on page 23).
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 EQ PRE COMP. switch the EQ module can be switched in front of the compressor module.
This allows it to be used either as a final compressor or limiter (further information in the
section “EQ PRE COMP.” on page 17).
LIMIT
The LIMIT switch turns the compressor into a limiter. The COMPRESSION control serves the
purpose of controlling the threshold. The Limiter does not function as a peak limiter, in other
words there is no guarantee that all peaks are included. It is therefore advisable when modu-
lating a subsequent unit that a headroom of 2 to 4 dB remains. Now peaks can be intercepted
very well and unobtrusively. Peak limiters have a system-based disadvantage in producing
audible distortions considerably sooner, so with regard to both sound quality and recording
safety, we think the soft limiter mode is the better choice for a recording channel strip.
