`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.
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.
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.
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.
INTERNAL JUMPER SETTINGS MONO INPUT CHANNELS The Mono Input channels are provided with three selectable options, using push-on jumpers on the circuit board. To change the settings, simply pull off the jumper and replace on the adjacent pair of pins. The default settings are shown as shaded on the diagram below.
Using The Console MONO INPUT CHANNEL Two inputs are available to the mono input channel, via XLR connector (normally for microphone sources) or 3-pole 1/4” ‘A’ gauge jack socket for signals needing a higher input impedance such as keyboards, drum machines, synths or tape machines. Both input sockets are permanently active, and may be used simply by plugging the source into the required input.
out low frequency hum. 5 EQUALISER The Equaliser(EQ) comprises four sections. The upper control provides H.F.(treble) boost and cut of +/-15dB at 13kHz, and the lower control provides L.F. (bass) boost and cut of +/-15dB at 60 Hz. The centre two pairs of knobs are arranged as HI and LO MID frequency sections, with a cut/boost control (lower knob) of +/- 15dB, and a SWEEP(frequency) control which determines at which frequency the boost/cut action will be centered.

11 MUTING All outputs from the channel except Inserts may be muted by pressing the MUTE switch, and the associated LED illuminates to show that the channel is OFF. Alternatively the channel may be selected to any one or more MUTE BUSES to provide grouped muting under the control of the MUTE masters on the far right-hand side of the console.
STEREO INPUTS Each Stereo Input section comprises two independent pairs of inputs. The Stereo Input feeds a full- facility input channel, very similar to the mono input. The second input is intended for a cassette or CD source, typically to provide background music before a performance and are fed to the stereo mix only and Aux 1 &...

18 EQUALISER The Equaliser section has HF and LF shelving controls, each with a range switch to provide two centre frequencies for each control. Turn the HF knob to the right to boost high (treble) frequencies by up to 15dB at a choice of 6kHz or 12kHz centre frequencies, adding crispness to percussion from drum machines, synths and electronic instruments.

MUTING All post-fade outputs from the channel may be muted by pressing the MUTE switch, and the associated LED illuminates to show that the channel is OFF. Alternatively the channel may be selected to any one or more MUTE BUSES to provide grouped muting under the control of the MUTE masters on the far right-hand side of the console.
GROUP SECTION The Group outputs are available on XLR connectors, and a pre-fade insert point is also provided on 3-pole 1/4” jacks. The Groups may also feed the stereo Mix (see 27, below) or the Matrix outputs (see 28, below). 26 GROUP FADERS These 100mm long-throw fader determine the level of the Group signal.
MASTER SECTION 31 MIX FADERS The MIX FADERS set the final level of the Mix outputs. The faders should normally be set close to the ‘0’ mark if the input channel levels have been set correctly. Pre-fade INSERTS are provided for connection of external processing equipment (e.g. Graphic EQ or compressor/limiters) if required.
39 MONO CHECK Normally the Phones output monitors the Stereo Mix. Pressing the MONO CHECK switch sums the L & R outputs to check for phasing problems. The main outputs are not affected by the position of the switch. 40 MUTE MASTERS Four MUTE MASTER switches provide muting control of any channels which have been assigned to a mute group using the M1-M4 switches on the input channels.
Applications APPLICATION 1 - LIVE SOUND REINFORCEMENT This drawing shows a typical configuration for sound reinforcement, with the main PA fed from Mix L/R and a secondary system fed from the Matrix outputs. The illustration shows the flexibility of the inputs to the mixer and how the direct outputs are available as sources for a multitrack tape machine.
APPLICATION 2 - LIVE SOUND WITH CENTRE CLUSTER This configuration is similar to application 1, but with the addition of a voice cluster and mono fill, both fed from the Matrix outputs. The source for the Matrix could be the main Mix, or a combination of Mix and Groups. The first three Aux sends are used as mono feeds to Effects Units, brought back to the Mix on the Stereo Returns.
APPLICATION 3 - ADDITIONAL STEREO INPUTS This illustration shows how the number of Stereo Inputs to the Mix may be expanded by using the Stereo Returns for sources such as keyboards and drum machines, when the normal Stereo input channels are already used. Additional stage foldback is provided by the Matrix outputs in this example.
APPLICATION 4 - THEATRE SOUND In this application the main requirement is to drive a large number of separate loudspeaker outputs for spot sound effects. The Groups, Mix, Aux Sends and Matrix outputs are all used for this purpose. Each could be provided with Graphic EQ or Delay units as required.
