3. QUICK START
This is the fastest way to get something out from your GHIBLI 16(FX) if you have a
keyboard and a microphone.
Plug the microphone into Channel 1 MIC IN.
Turn down GAIN, AUX and LEVEL controls.
Put the EQ controls on center position.
Keep MAIN MIX LEVEL control on mid position.
Turn on your GHIBLI 16(FX).
Sing or speak in to the microphone with normal volume and adjust the GAIN control
so that the Master LED Meter stays around "0" and never exceed 10.
If you like, you can add some equalization at this stage.
Connect speakers and amplifiers and turn them ON.
Turn up Channel 1 fader to "0" and the LEFT/RIGHT main fader to one quarter
Connect your stereo keyboard into channel 5/6 and turn on the channel Level on
mid position.
Here you are. It is your first mix with your GHIBLI 16.

1 MIC INPUT(1 to 4)
Your GHIBLI 16(FX) is equipped with 4 low-noise microphone preamplifiers with
phantom power always on, 50 dB of Gain and over 100 dB of S/N ratio. You can
connect almost any type of microphone. Dynamic microphones do not need
phantom power. Phantom power will not damage your dynamic microphones but it
may damage tube or ribbon microphones, so make sure to read the microphone
instructions manual before connecting such types of microphone to your
GHIBLI 16(FX). These four channels are also equipped with 1/4" TRS balanced or
unbalanced LINE-IN plugs to connect line-level instruments such as keyboards,
drum machines and effect devices.
NOTE: Phantom power is applied only to the XLR MIC socket but not to the
LINE IN 1/4" socket. Phantom Power may damage line-level instruments such as
keyboards, so never connect such instruments to the XLR socket. Always use the
1/4" socket.
2 INSERT
This is where you connect external sound processors such as compressor-limiter,
equalizers, etc. The insert point is available on the first 4 MIC channels only. For
the other channels, you can always insert the processor in between the sound
source (such as keyboard or drum machine) and the GHIBLI input. The Insert
sockets can also be used as direct-outs to feed the input of a 4-track tape
recorder.
3 STEREO LINE INPUTS (5 to 8)
These are channels 5/6 and 7/8. They are organised in stereo pair and provided
with 1/4" TRS phone sockets. If you connect only the left jack, the input will operate
in mono mode, that is, the mono signal will appear on both input channels. You can
use these inputs with a stereo keyboard, drum machine, etc.

4 STEREO LINE INPUTS (9 to 16)
These are channels (9/10-11/12) and (13/14-15/16). They are organised in double
stereo pair and provided with 1/4" TRS phone sockets. You can connect either
mono or stereo line-level instruments or use them as stereo return for external
multi-effects.
5 AUX OUT 1 & 2
These 1/4" phone sockets are used to send out the signal from the AUX bus of
the input channels into external devices such as effect units and/or stage monitors.
You can use AUX OUT 2 to feed powered stage monitors. Use AUX OUT 2 only for
internal/external effect since this AUX bus 2 is only post-fader.
6 MAIN MIX OUTPUTS
These low-impedance outputs are fully balanced and can drive +4 dBu lines with very
high headroom. You can connect the inputs of a stereo power amplifier of a pair of
powered speakers.
7 PHONES
This socket will be used to send the signal to a headphone or to a pair of powered
studio monitors.
8 CENTER & SURROUND OUT
Both the CENTER and SURROUND channels are available on this socket. You must
use a stereo Y type cable. (The same cable you use for the INSERT sockets). The
CENTER signal will appear on the TIP of the jack. The SURROUND channels will
appear on the RING.

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.
You 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. You 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
Your 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.
To 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

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.

EQUALIZATION
You have three EQ control for each mono and stereo input channel each providing
+/-15 dB of boost and cut. The signal will be unaffected when the controls on center
position. You may use an external equalizer to make up a mix properly, but a master
equalizer will not have effect on a single channel and you may overload the signal easily.
Individual EQ will give you a much better control on single tracks.
12 -HI
If you turn this control up, you will boost all the frequencies above 12 kHz (shelving
filter). You will add transparency to vocals and guitar and also make cymbals crispier.
Turn the control down to cut all frequencies above 12 kHz. In such way, you can
reduce sibilances of human voice or reduce the hiss of a Tape player.
13 -MID
This is a peaking filter and it will boost/cut frequencies from 600 to 5000 Hz
depending on the position of the MID freq control. This control will affect especially
upper male and lower female vocal ranges and also the harmonics of most musical
instruments.
14 --LOW
If you turn this control up, you will boost all frequencies below 80 Hz. You will give
more punch to bass drums and bass guitar; and you will make the male vocalist
more "macho". Turn it down and you will cut all the frequencies below 80 Hz. In this
way, you can avoid low-frequency vibrations and resonance thus preserving the life
of your woofers.
15 AUX sends
These two controls are used to adjust the level of signal sent to AUX 1&2 outputs
(if nothing is connected to AUX2 OUT socket, the signal will be sent to the resident
digital multi-effect ), and such adjustment doesn't affect the main mix output signal
at all. AUX1 is configured pre-fader. It means that the signal is sent to the AUX1
OUT socket before the channel LEVEL control. This Bus is used to feed stage
monitors.
16 PAN
This is the PANORAMA control, or balance control. You can adjust the stereo image
of the signal via this control. Keep this control in center position and your signal will
be positioned in the middle of stage. Turn this control fully counter-clockwise and the
signal will be present only on the left speaker and vice-versa. Of course a large
number of intermediate positions are available.

feed stage monitors via the AUX control. In the channels
marked 9-12 and 13-16, you can connect a double stereo
channel to each single input. In this case, you will have a
stereo channel on the LEFT input and another stereo
channel on the RIGHT input. You will find out that if you do
not need a large number of line-level sources, you can use

This consists of two column of 4 LEDs
each ranging from 20 dB to +10 dB.
The 0 (yellow) LED corresponds to a level
output of 0 dBu. The 10 ( red ) LEDs
come to life when the output reaches
+10dBu. Set the MAIN MIX level control
so that the 10 LEDs only flash occasionally.
In general, you get a good mix level when
the Meter LEDs operate in the range -10
to 0. If you exceed 0, you will get distortion.
If even 20 LEDs are sleeping, your
signal-to-noise ratio will suffer.

presets are available in a sequence and via a single control, GHIBLI 16FX multi-effect
unit is organized with a 16 presets control and relative Level control for vibrato and
modulation controls such as chorus and flanger. You can add reverb at any time with
a separate Level control or you can just use the reverb keeping the FX level control

5. INSTALLATION AND CONNECTION
OK, you have got to this point and you are now in the position to successfully operate
your GHIBLI 16(FX): However, we advise you to read carefully the following section to
get the best out of your GHIBLI 16(FX).
Not paying enough attention to the input signal level, to the routing of the signal and
the assignment of the signal will result in unwanted distortion, a corrupted signal or
no sound at all. So you should follow these procedures before operation:
1. Before connecting microphones or instruments, make sure that the power of all
your systems components including the GHIBLI 16(FX) is turned off. Also, make
sure that all input and output controls are turned down. This will avoid damage to
your speakers and excessive noise.
2. Properly connect all external equipment such as microphone, power amplifier,
speakers etc.
3. Now, turn on the power of any peripheral devices, then connect the 18 VAC power
supply to your GHIBLI 16(FX) and to the AC socket.
NOTE: The power amplifier or powered monitors shall be turned ON after the
GHIBLI 16(FX) and OFF before the GHIBLI 16(FX) is turned OFF.
4. Set the output level of your GHIBLI 16(FX) or the connected power amplifier at no
more than 75%.
5. Set the PHONES level at no more than 50%.
6. Set HI, MID and LOW EQ controls on center position.
7. Set panoramic ( PAN / BAL ) control on center position.
8. While speaking into the microphone (or playing the instrument) at normal volume,
adjust the channel gain control until the 0dB LED lights up; in this way, you will
maintain good headroom and proper dynamic range.
9. You can shape the tone of each channel by adjusting the equalizer controls as
desired.
10.Now repeat the same sequence for all input channels. The Main LED Meter could
move up into the red section. In this case, you can adjust the overall output level
through the MAIN MIX control..
