Ensure that the mains source voltage (AC outlet)
matches the voltage rating of the product. Failure
to do so could result in damage to the product and
possibly the user.
Unplug the product before electrical storms occur
and when unused for long periods of time to reduce
the risk of electric shock or fire.
External Connection
Always use proper ready-made insulated mains
cabling (power cord). Failure to do so could result
in shock/death or fire. If in doubt, seek advice from
a registered electrician.
Do Not Remove Any Covers
Within the product are areas where high voltages
may present. To reduce the risk of electric shock do
not remove any covers unless the AC mains power

4.1 THE MIC/LINE INPUT
1
These are Channel 1 through Channel 4. You can connect balanced, low
impedance microphones or a low level signal to the XLR socket. On the
1/4" Line jack you can connect either a microphone or a line level instru-
ment .
Note: You shall never connect an unbalanced microphone to the XLR
socket if you do not want to damage both the microphone and the mixer.
Also, it is not possible to simultaneously use both the MIC&LINE inputs
on the same channel, use only one of them for the appropriate source on
each channel.
- PHANTOM POWER +18 Volts
It is available only on the XLR input sockets. Please make sure the power
switch is turned off before connecting a microphone to the XLR input.

4.2 MONO CHANNEL INSERT
2
Insert points are provided for mono MIC channels, which can allow you to
patch external signal processing devices into signal path. When you insert
a TRS jack in the insert socket, the signal will be taken out after the channel
compressor, sent to an external processor, and returned into the channel
strip immediately before the EQ section. Of course, the jacks used must be
stereo (Tip Send/Ring Return).
4.3 STEREO INPUT (CH5~CH16)
3
Each stereo channel comes with two unbalanced line level inputs on 1/4"
TRS jacks, which are used to connect left and right input signals. Use the
LEFT input when connect a mono input signal to the STEREO INPUT. The
last two stereo channels feature an original and exclusive double stereo
input for each stereo channel. This feature allows you to connect two stereo
sources at the same time for each stereo channel, enlarging the real
number of signals you can manage at the same time.

4.4 LOW CUT
4
By pushing this switch you will activate a 100Hz low frequency filter that
provides a precise cut for frequencies under 100Hz. You can use this facility
to reduce the hum noise infected by the mains power supply, or the stage
rumble while using a microphone.
4.5 THE TUBE SOUND COMPRESSOR SWITCH
5
The TSC switch (on the first 4 channels) activates the TUBE SOUND
COMPRESSOR and let you choose between Compressor and De-esser
functions. The two yellow LEDs show the amount of compression applied
to the input signal. Two algorithms are provided, one for soft compression
with a threshold level of 0dB, and one for hard limiting with a threshold
level of around +10dB. This dynamic processor works on the very entry
stage of the channel and it can avoid also the channel clipping, maintain
the best signal-to-noise ratio. The compression algorithm applied to the
sound is shown by two yellow LEDs.
6
4.6 CLIP LED/0dB LED
6
The green LED illuminates when the signal overpasses the 0dB level,
the red CLIP LED illuminates when the channel is going into overload.
If the CLIP LED becomes permanently on, reduce the amount of gain.
To have best signal-to-noise ratio set the gain so that the green 0dB LED
becomes lighted.
4.7 INPUT LEVEL SETTING
7
This control is provided with 2 different indication rings: one is for the
MIC input and the other for the LINE input. When you use a MIC input
you shall read the INSIDE ring (0~50dB); when you use a LINE input
you shall read the OUTSIDE ring (-20~+30dB).
4.8 The 3 BANDS EQUALISER
-HI
8
This is the treble control. You can use it to get rid of high frequency noises
or to boost the sound of cymbals or the high harmonics of the human
voice. The gain range goes from -15dB to +15dB with a center frequency
of 15kHz.
- MID
9
This is the midrange control. It can affect most fundamental frequencies
of all musical instruments and human voice. An attentive use of this
control will give you a very wide panorama of sound effects. The gain
range goes from -15dB to +15dB.
- MID FREQUENCY SWEEP
10
This control allow to choose the ceuter frequency of the mid band in a
range going from 600Hz to 5KHz.
- LOW
11
This is the bass control. It is used to boost male voice, kickdrum or bass
guitar. Your system will sound much bigger than what it is. The gain range
goes from -15dB to +15dB and the center frequency is 80Hz.
4.9 AUX 1& 2
12
This control is used to adjust the level of respective channel signal sent
to the Auxiliary Bus. The configuration of AUX1 is pre-fader so the signal
sent to the AUX Bus 1 will be affected by the LEVEL control of thatnot
particular channel. The AUX2 is post-fader so the signal sent to AUX Bus
2 will be affected by the channel LEVEL control. In this GHIBLI 16FX,
The AUX2 signal also feeds the internal digital effect processor.
4.10 PAN
13
This is the PANORAMA 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 counterclockwise and the signal will be present only on the left speaker and viceversa. Of course a wide number of intermediate positions are available.

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 be the real master of your own mixer. 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 for every single channel:
1). Before connecting mics or instruments, make sure that the power of all your systems components including the
mixer is turned off. Also, make sure that all input and output controls of your mixer are turned down. This will avoid
damage to your speakers and avoid excessive noise.
2). Properly connect all external devices such as microphone, power amplifier, speakers etc.
3). Connect the 24V AC adapter to the mixer and main power.
4). Now, turn on the power of any perpheral devices, and then power up the mixer.
Note: the power amplifier or powered monitors shall be turned on after the mixer and turned off before the mixer.
5). Set the output level of your GHIBLI 16(FX) or the connected power amplifier at no more than 75%.
6). Now, set the PHONE level at no more than 50%.
7). Set HI, MID and LOW EQ controls on the middle position
8). Set panoramic controls on the middle position.
9). While speaking into the mic (or playing the instrument), adjust the channel level control so to maintain a good
headroom and ideal dynamic range.
10). You can shape the tone of each channel by adjusting the equalizer controls as desired.
11). Now repeat the same sequence for all other 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.
12). For GHIBLI 16FX, you can select desired DSP sound effects via PRESET and FX & REVERB LEVEL controls.
