3. READY TO START?

3.1 Please check the AC Voltage available in your Country before connecting
your S-8 to the AC socket.

3.2 Be sure that the main power switch is turned off before connecting the
Mixer to the AC socket. Also, you should make sure that all Input and
Output Controls are turned down. This will avoid damages to your speakers
and avoid excessive noise.

3.3 Before turning on the S-8 you shall connect it to a power amplifier and
urn-on the mixer BEFORE the power ampifier. Once you have finished your
working session you shall turn the mixer off AFTER the power amplifier.

3.4 Before disconnecting the S-8 always turn-off the Power switch.

3.5 Do not use solvents to clean your S-8. A dry and clean cloth will be OK.

1 The Mono MIC/LINE Channels

These are Channel 1 through Channel 4. You
can connect balanced, low impedance micro­phones to the XLR socket. On the 1/4" phone
jack you can connect either a microphone or
a line level instrument. You shall never connect
an unbalanced microphone to the XLR socket
if you do not want to damage both the Micro­phone and the Mixer.

2 Input Level Setting

This Control is provided with 2 different
indication rings: One is for the Microphone
and the other for the Line levels. When you
use a microphone you shall read the outside
ring (0-60 dB), When you use a Line level
instrument you shall read the INSIDE ring
(+15~-45 dB). For optimum operation you
shall set this control in a way that the peak
LED will blink also occasionally in order to
avoid distortion on the input channel.

3 Low-cut Filter

By pressing this button you will activate a
75 Hz low frequency filter with a slope of
18 dB per octave. You can use this function
to reduce hum and stage rumble when
using microphones.

4 48 Volt Phantom Power

It is available only to the XLR Mic sockets.
Never plug in a microphone when phantom
power is already on. Before turning phantom
power on, make sure that all faders are all
the way down. In this way you will protect
your Stage Monitors and Main Loudspeakers.

5 STEREO INPUTS

These are Channel 5 through 8. They
are organised in stereo pair (5&6 pair
also features XLR Mic Input) and they
are provided with 1/4" TRS phone
sockets. If you connect only the left
jack, the input will operate in mono
mode.

The 3 BANDS EQUALISER

A 3-band equaliser is provided for all
input channels with a wide range of
frequency adjustment.

6 HI

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 centre
frequency of 12 kHz.

7 MID

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 and very
wide panorama of sound effects. The gain
range goes from -12dB to +12dB and the
centre frequency is 2.5 kHz.

9 AUX SENDS

These two controls will send the audio signal out to
Auxiliary busses. AUX 1 is configured as PRE-FADER.
It means that the signal is sent out before reaching
the main Fader. This will be used for stage monitors.
AUX 2 is configured as POST-FADER; therefore, the
audio signal will be affected by the Main Channel Fader.
This will be used for effects and sound processors.
However, Aux 2 can also be configured as Prefader
through any internal modification. (Please see "MODIFI­CATIONS" later in this Manual.)

10 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 counterclockwise and the signal
will be present only on the left speaker and vice-versa.
Of course a wide number of intermediate positions is
available.

11 PEAK

Inside your S-8 the audio signal is monitored in several
different stages and then sent to the PEAK Led. When
this Led blinks, it warns you that you are reaching signal
saturation and possible distortion. The PEAK Led will blink
with a level that is 6dB before actual clipping.

4. CONTROL ELEMENTS

Insert points are provided for
the Mono Mic Channels. When
you insert a jack in the insert
socket, the signal will be taken
out after the Input Gain Control
(Trim), sent to an external
processor such a compressor
limiter, and returned into the
channel strip immediately before
the EQ section. Of course, these
jacks used must be stereo
(Tip Send/Ring Return).

and the level will be adjusted in level by the Control Room knob. If you push
down the 2TR TO MIX button, the 2 TRACK IN signal will be routed into the
MAIN output and will be adjusted in level by the MAIN MIX LEVEL knob.

17 AUX RETURN

The Auxiliary Return 1 and 2 are in fact two additional stereo Line inputs.
AUX RETURN 1 is configured to be assigned permanently to the Main Mix.
(It operates in Mono Mode if you connect only the left jack).The EFX TO AUX1
button is used to switch the signal from AUX RETURN 2 between MAIN MIX
and AUX SEND 1. If a signal is routed to AUX RETURN 1 and no signal is
connected to AUX RETURN 2, depressing the EFX TO AUX 1 will route the
signal to AUX SEND 1, which level will be controlled by AUX RETURN 2.
Without doubt, this feature will be very useful for you.

These 1/4" TRS sockets will route the main mix into a tape recorder.

22 STEREO AUX RETURN

Use these stereo 1/4" phone socket to return the sound of an effect unit or
sound processor to the Main Mix. Alternatively you can use them as an extra
auxiliary input.

inputs. Never connect microphones when the Phantom Power is on already.

26 AC INLET WITH FUSE HOLDER

Use it to connect your S-8 to the Main AC with the supplied AC cord. Please
check the Voltage available in your Country and make sure the voltage is
identical to the values marking on the product. Replace the fuse with the
same type by the qualified personnel only

27 MAIN MIX OUTPUT

This stereo output is supplied both with XLR and 1/4" jack socket and it is
controlled by the Main Mix Level on the front panel. It will send the audio

signal to an amplifier. The output level can be varied from -∞ to +15dB.

28 CONTROL ROOM OUTPUT

These 1/4" phone sockets will be used to send the signal to Studio Monitor
speakers or to a second set of PA.

5. INSTALLATION AND CONNECTION

Ok, you have got to this point you are now in the position to successfully
operate your S-8. However, we advise you to read carefully the following
section to be the real Master of your own Mix. Not paying attention enough
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 this procedure for every single channel:

˙Turn down all Input and Output Gain Controls.
˙Connect phantom powered microphones before switching on the +48Volt

Phantom Power switch.

˙If you have a power amplifier connected to your S-8 set the Level of the

amplifier at no more than 70%.

˙Now set the CONTROL ROOM/PHONES level at no more than 50%. In this

,

way you will be able to hear later what you are doing connecting a pair of
headphones or a pair of powered studio monitor speakers.

˙Position HI, MID and LOW eq controls on middle position.
˙Position panoramic (PAN) control on centre position.

˙With a headphone or studio monitor speakers connected apply a Line Level

input signal so that the PEAK Led does not light up.

At this point increase the input gain so that the PEAK led will blink occasionally.

˙

In this way you will maintain good headroom and ideal dynamic range.

˙ Now connect a microphone and ask the singer to sing loud into the microphone.

Turn slowly the Gain Control clockwise and have the PEAK Led blink only
occasionally.

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.

As we have told you previously in this Manual, the Aux Send 2 Control both on
Mono and stereo channels is factory wired as POST-FADER. If you have some
