9 LOW-CUT filter
Also regarded as high-pass filter . This filter will cut low
frequencies below 100 Hz with a slope of 18 dB x octave.
Y ou should always activate this filter when using microphones.
In this way, you reduce the possibility of feedback and
resonance due to stage vibrations. Do not use the filter
with bass drums and bass guitar , if you want to preserve
the full body of these instruments. There is a creative
way to use the low-cut filter with the channel LOW
equalization control. Y ou can boost a male vocal track
with the channel LOW level control at 80 Hz and
immediately after apply the low-cut filter . In this way, you
add the wanted colourations to the voice avoiding stage
rumble and breath pops.
10 COMPRESSOR/DE-ESSER
Y our GHIBLI 16(FX) also includes a flexible and easy to use
tube-like compressor and de-esser . It is really a powerful
dynamic processor using optical compression just like the
best Tube Compressors. Two internal automatic settings
are provided, one for smooth compression with a threshold
level of 0 dB, and one for hard limiting with a threshold level
of around +10 dB. The soft and hard knee curve is
automatic and it is shown by the two yellow LEDs, HARD
and SOFT. This dynamic processor can also avoid the
channel clipping, maintaining the best signal-to-noise ratio.
T o set the right amount of compression turn up the GAIN
control. Higher the gain, higher is the compression ratio.
With the switch in BYPASS position the compressor will be
sleeping, In COMP position the Compressor is alive while
you can activate the de-esser filter with the switch in such
position. The de-esser filter is very useful to get rid of vocals
sibilances and tape hiss.
11 GAIN
This control is provided with 2 different indications: one is for the MIC and the
other for the LINE input. When you use a Microphone you shall read the MIC
ring (0~50dB); when you use a line level instrument you shall read the LINE
ring (-20~+30dB). For optimum operation you shall set this control in a way
that the CLIP LED will light up only occasionally in order to avoid distortion on
the input channel.
