6.7 Clip indicators
There are three critical places in the signal path of the FCS 966 that are
monitored by the clip indicator circuit; if one or more of these overloads,
the indicator is illuminated. These three places are: the output of the contour
section, the output of the main equalizer section, and the output from the gain
control section. Three point monitoring is required as it is easy to place the
controls in positions that allow the overload of one section without this being
obvious on the meter. The clip indicator provides instant confirmation that no
part of the FCS 966 is being headroom compromised.
6.8 Frequency band
sliders
The main function of the FCS 966 is controlled with the frequency band
sliders, which split the audible spectrum into thirty independent bands,
centred on standard ISO frequencies. Each band may be amplified (boosted)
or attenuated (cut) by up to 15dB, allowing great control over the program for
either corrective or creative purposes. Normally, such a large control range on
each slider could cause problems if the unit was being used for fine control.
This is not a problem with the FCS 966 sliders, which provide a fine level of
control near the centre or ‘zero’ position, progressively getting more aggressive
as the control is advanced towards the ends of the travel. Thus both fine,
musical adjustments and radical audio surgery are possible without operational
compromise. When the slider is in the central position it is effectively out of
circuit.
