Introduction
Congratulations on your purchase of a LIVE 8 mixer. Owning a Soundcraft console brings you the expertise and support of one of the
industry’s leading manufacturers and the results of over 22 years experience supporting some of the biggest names in the business.
Designed by engineers who understand the individual needs of musicians, LIVE 8 has been built to the highest standards using quality
components and employing automated assembly techniques beyond the reach of most manufacturers of compact mixers.
A rugged steel chassis is combined with moulded side trims to give protection and distinctive appearance. Custom moulded controls,
designed for the best `feel’ and visual clarity complement the styling, resulting in a truly professional product which is ideal for both
touring and fixed PA installations.
LIVE 8 is available in 24, 32 & 40 channel frame sizes. All frame sizes incorporate removeable side cheeks to enable the console to be
fitted compactly in a flight case.
LIVE 8 incorporates circuit technology identical to that used on some of the most sophisticated Soundcraft consoles, including new
surface mount component techniques. The input channels are able to accept a wide range of Microphone and Line level signals from
separate input sockets. Every channel features the UltraMic+™ input with wide range gain control, Phase switch, 4-band Equalisation
with swept Hi and Lo Mid ranges, plus a Hi-Pass Filter, 6 Auxiliary Sends (2 pre-fade, 2 pre or post and 2 post-fade), PFL(Pre Fade
Listen), Peak LED, Panning to a Stereo Bus and routing in pairs to eight Output Groups. Each channel has a separate Direct Output
and is controlled by a high-quality long throw fader. All input channels may be assigned to a choice of four Mute Groups.
All frame sizes are provided as standard with 2 dedicated stereo inputs. Each stereo input comprises two separate input sections, one
provided with comparable facilities to the mono inputs, and one more basic input for a cassette or CD player which routes to the stereo
mix and two of the Aux outputs only.
The eight Output Groups provide submixing to the Mix L/R, either as stereo pairs or as mono sends to L & R. The Group outputs are
available on separate connectors to feed external equipment directly. Each Group section incorporates matrix sends, PFL monitoring
& bargraph metering. Eight external Stereo Return inputs are provided for effects or submixing from external sources and these route
to Mix or to a pair of Groups.
Two Matrix outputs receive sends from each Group or Mix L & R as required.
The Master section provides master level control for the Left, Right, Matrix and Auxiliary Send buses, with separate AFL monitoring on
each Matrix and Auxiliary output.
The Mix L/R and Group outputs all have insert points for the connection of external signal processing or graphic equalisation.
Comprehensive Talkback facilities are provided, which allow a talkback microphone to be routed to Mix L/R, Groups and Auxes 1-2 or
3-4. Ten 12-segment, 3-colour peak reading LED bargraph meters provide clear display of Mix L/R, Group and PFL signals. Pressing
any PFL or AFL switch puts the selected signal onto both sides of the headphones output and the L & R bargraph meters in place of
the Mix signal. Two LEDs monitor the status of the console power supply.
LIVE 8 is designed to be as user-friendly as possible, but a few minutes spent reading through this manual will help you become familiar
with the product away from the pressure of a live session, and allow you to gain full benefit from the superb performance offered by your
new mixer.
Above all, remember that your Soundcraft mixer is designed to extend your creativity. The more you explore the controls and the effect
they have on the sound output, the more you will appreciate how you can influence and enhance the final sound.

read this section carefully.
General Precautions
Avoid storing or using the mixing console in conditions of excessive heat or cold, or in positions where it is likely to be subject to vibration,
dust or moisture. Do not use any liquids to clean the fascia of the unit: a soft dry cloth is ideal.
Avoid using the console close to strong sources of electromagnetic radiation (e.g. video monitors, high-power electric cabling): this may
cause degradation of the audio quality due to induced voltages in connecting leads and chassis.
Caution! In all cases, refer servicing to qualified personnel.
Handling and Transport
The console is supplied in a strong carton. If it is necessary to move it any distance after installation it is recommended that this packing
is used to protect it. Be sure to disconnect all cabling before moving. If the console is to be regularly moved we recommend that it is
installed in a foam lined flightcase. At all times avoid applying excessive force to any knobs, switches or connectors.
Power Cable
Always use the power supply cable supplied with the mixer: the use of alternative cables may cause damage and voids the warranty.
W a r n i n g ! In the event of an electrical storm, or large mains voltage
fluctuations, immediately switch off the mixer and unplug from the mains.
Signal Levels
It is important to supply the correct input levels to the console, otherwise signal to noise ratio or distortion performance may be
degraded; and in extreme cases, damage to the internal circuitry may result. Likewise, on all balanced inputs avoid sources with
large common mode DC, AC or RF voltages, as these will reduce the available signal range on the inputs. Note that OdBu =0.775V
RMS.
Refer to the Specifications section for details of input and output levels.
DPS-3 POWER SUPPLY
The LIVE 8 is supplied with a DPS-3 power supply unit. Consult the DPS-3 manual before making any connections. Always use the
power supply which is supplied with the console.
Ensure that the DPS-3 power supply is NOT connected to the Mains and is turned OFF.
The power supply can be positioned anywhere within reach of the LIVE 8 and an available power socket, but it is best rack-mounted in
a position where airflow through the vents is not obstructed, and where the power switch or cables cannot be accidentally knocked.
Connect the multi-way power cable between the DPS-3 and the LIVE 8 power connector. Screw the connector locking rings clockwise
on both units to secure the cable. The locking rings should be firm, but not tight. Connect the IEC type mains cable to the mains input
socket on the DPS-3. Connect the other end to the nearest plug socket and switch on the power to the DPS-3.

MAINS INSTALLATION
General Wiring Procedures
To take full advantage of the excellent signal to noise ratio and low distortion of Soundcraft consoles, care must be taken to ensure that
incorrect installation and wiring does not degrade the performance of the desk. Hum, buzz, instability and Radio Frequency interference
can usually be traced to earth loops and inferior earthing systems. In some areas, especially heavily industrial areas, the incoming mains
earth will not be adequate and a separate technical earth for all the audio equipment must be supplied. However, check with your local
electricity supply company to ensure that safety regulations are not infringed or negated.
The successful, hum free, installation of a system requires forethought, and the establishment of a set of ground rules, which must be
consistently adhered to at all stages of installation.
Initial Wiring Considerations
For optimum performance, it is essential for the earthing system to be clean and noise free, as all signals are referenced
to this earth. A central point should be decided on for the main earth point system, and all earths should be 'star fed' from
this point. It is common electrical practice to `daisy chain' the earths to all electrical outlets but this method is unsuitable for
audio installations. The preferred method is to run an individual earth wire from each outlet, back to the system star point
to provide a safety earth screen reference for each piece of equipment.A separate earth wire should also be run from each equipment
rack and area, to the star point. This may or may not be used depending on circumstances, but it is easier to install in the first place, than
later when problems arise.The location of the star point should be a convenient, easily accessible place, preferably at the rear of the
console or in the main equipment rack.
Install separate 'clean' and 'dirty' mains outlets, wired individually back to the incoming mains distribution box. Use the 'clean' supply for
all audio equipment and the `dirty' supply for all lighting, etc. Never mix the two systems.
If necessary, to provide sufficient isolation from mains borne interference, install an isolating transformer. This should be provided with
a Faraday Shield which must be connected with earth.
Never locate the incoming mains distribution box near audio equipment, especially tape recorders, which are very sensitive to electromagnetic fields.
Ensure that all equipment racks are connected to earth, via a separate wire back to the star point.
Equipment which has unbalanced inputs and outputs may need to be isolated from the rack to prevent earth loops.
Audio Wiring
Having provided all equipment with power and earthing connections, consideration must be given to the method of
providing audio interconnection and adequate screening of those interconnections. This must be done in a logical
sequence to avoid problems and assist in the localisation of problem equipment.
Connect the FOH or Monitor system to the console and check for any hum, buzz, or RFI. Only when you are satisfied with the quietness
of the console and the PA system should you proceed with the next step.
Connect stereo or Multitrack Tape recorders, FX and foldback sends one at a time, checking and isolating any connection which
degrades performance.
Connect all other peripheral devices.
Connect all microphone lines.
By following this sequence much time and future trouble will be saved, and the result will be a quiet, stable system.
Shielding
Audio equipment is supplied with a variety of input and output configurations, which must be taken into consideration when
deciding where the screen connections should be made. There are three sources of unwanted signal being impressed on
the screen, which are as follows:
Extraneous electrostatic or electromagnetic fields.
Noise and interference on the earth line.
9
Capacitive coupling between the screen and signal wires.
To minimise the adverse affects of the unwanted coupling to the signal wires, it is important that the screen is connected at one end only,
i.e. the screen must not carry any signal current. Any signal on the wires within the screen will be capacitively coupled to the screen. This
current will ultimately be returned to the source of the signal, either directly, if the screen is connected at the signal source end, or
indirectly via the earthing system, if the screen is connected at the signal destination end. The indirect connection will cause an increase
in high frequency cross-talk, and should be avoided wherever possible.
Therefore, in general, always connect the shield only at the signal source end. In high RF areas, the screen can also be connected to
earth via a 0.01 mF capacitor. This will present a short circuit at RF frequencies, thus lowering the effective shield impedance to ground.
However, at low audio frequencies the reactance of the capacitor will be sufficiently high not to cause an earth loop problem.
Points to Remember
In all cases, use good quality twin screened audio cable. Check for instability at the output.
Always connect both conductors at both ends, and ensure that the screen is only connected at one end.
Do not disconnect the mains earth from each piece of equipment. This is needed to provide both safety and screen returns to the system
star point.
Equipment which has balanced inputs and outputs may need to be electrically isolated from the equipment rack and/or other equipment,
to avoid earth loops.
It is important to remember that all equipment which is connected to the mains is a potential source of hum and interference and may
radiate both electrostatic or electromagnetic radiation. In addition, the mains will also act as a carrier for many forms of RF interference
generated by electric motors, air-conditioning units, thyristor light dimmers etc. Unless the earth system is clean, all attempts to
improve hum noise levels will be futile. In extreme cases there will be no alternative but to provide a completely separate and
independent `technical earth' to replace the incoming 'noisy earth'. However, always consult your local electricity supply authority to
ensure that safety regulations are not being infringed.
WORKING SAFELY WITH SOUND
Although your new console will not make any noise until you feed it signals, it has the capability to produce sounds which when monitored
through an amplifier or headphones can damage hearing over time.
The table below is taken from the Occupational Safety & Health Administration directive on Occupational noise exposure (1926.52):

Conforming to this directive will minimise the risk of hearing damage caused by long listening periods. A simple rule to follow is the
longer you listen the lower the average volume should be.
Please take care when working with your audio - if you are manipulating controls which you don’t understand (which we all do when
we are learning), make sure your monitors are turned down. Remember that your ears are the most important tool of your trade, look
after them, and they will look after you.
Most importantly - don’t be afraid to experiment to find out how each parameter affects the sound - this will extend your creativity and
help you to get the best results.
