LIMITERS
Final Limiter Bass Drive
The Final Drive Bass Limiter is exactly the same control as the Final Limiter Main Drive, but applies to all the bass
frequencies, i.e. those between 5/30 Hz and 350 Hz.
Final Limiter Main Drive
The Final Limiter Main Drive is the last stage before the MPX stereo encoder, right between the Final Expander and the
Power Limiter. This control allows you to increase or decrease the substance of the audio material delivered to the MPX
encoder. The term MAIN refers to the fact that it operates on the 350 Hz to 15 kHz frequency range.
Warning:
as already mentioned, it is a very important and powerful command, and so overuse of the Final Limiter Main
Drive tends to overwork the "HF", i.e. the Main Final Limiter.
The Lookahead Limiter
The Lookahead Limiter is a predictive limiter that works on the final stage of the audio processor. Predictive means the
processor’s ability to know what and how much audio material will be inputted into the processor for processing and
outputting and then exactly the desired level of signal. While it is impossible to predict the future, it is possible to add a
small delay (an increase about 6-8ms in the overall delay) in the audio process stage, in order to change the level and
the waveform outputted by the processor in the event of strong variations in the input signal.
SuperBass
The SuperBass parameter acts directly on the compression of low frequencies below 100 Hz. The maximum compression
available is 15 dB. Operation of this control is very simple, but it is very powerful because it can influence the sound of low
frequencies considerably. This SuperBass works on the principle that if you cannot increase a parameter as it has already
reached the highest clipping levels, then to be able to bring it out further, it is advisable to reduce other parameters in order
to emphasise and increase the higher bandwidth selected and, in that case, the low frequencies.
Following this principle and reducing the frequencies between 150 Hz and 300 Hz at the same time, the Superbass
frequencies tend to emerge. Very high Superbass levels can cause strong compressor movements in Bandwidth 1. This
is absolutely normal, unless the limiter does not reach the
red
area. This condition indicates the need to limit use of this
control because the processor is not operating in the linear region.
