CAUTIONS The lightning flash with square symbol, is intended to alert the user to the presence of un-insulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. WARNINGS The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. NOTES Contain important information and useful tips on the operation of your equipment. HEADPHONES SAFETY WARNING Contain important information and useful tips on headphone outputs and monitoring levels. 2 USER GUIDE IMPORTANT Please read this manual carefully before connecting your mixer to the mains for the first time. © Harman International Industries Ltd. 2003 All rights reserved Parts of the design of this product may be protected by worldwide patents.

[. . . ] Many "faults" are the result of incorrect connection or control settings which may have been overlooked. Basic Troubleshooting is a process of applying logical thought to the signal path through the mixer and tracking down the problem by elimination. · Swap input connections to check that the source is really present. · Eliminate sections of the channel by using the insert point to re-route the signal to other inputs that are known to be working. · Route channels to different outputs or to auxiliary sends to identify problems on the Master section. · Compare a suspect channel with an adjacent channel which has been set up identically. · Problems with the Insert jack sockets contacts may be checked by using an insert bypass jack with tip and ring shorted together as shown to the left. If the signal appears when the jack is inserted it shows that there is a problem with the contacts on the jack socket, caused by wear or damage, or often just dirt or dust. If in doubt please contact Soundcraft customer support.

Phantom power can only be applied to both microphone inputs simultaneously so ensure that phantom power is off when not required. ONLY connect condenser microphones with the +48V powering OFF, and ONLY turn the +48V powering on or off with ALL OUTPUT LEVEL CONTROLS DOWN, to prevent damage to the mixer or external devices. TAKE CARE when using unbalanced sources, which may be damaged by the phantom power voltage on pins 2 & 3 of the XLR connector. The input level is set using the GAIN knob as described in point (7). 2 MIC INPUT 8 The MIC input accepts XLR-type connectors and is designed to suit a wide range of BALANCED or UNBALANCED signals. Professional dynamic, condenser or ribbon mics are best because these will be LOW IMPEDANCE. You can use low-cost HIGH IMPEDANCE mics, but the level of background noise will be higher. If you turn the PHANTOM POWER on (top right-hand side of the mixer) the socket provides a suitable powering voltage for professional condenser mics. 3 LINE INPUT Accepts 3-pole `A' gauge (TRS) jacks. Use this input for sources other than mics, such as keyboards, drum machines, synths, tape machines or DI'd guitars. The input is BALANCED for low noise and top quality from professional equipment, but you can use UNBALANCED sources by wiring up the jacks as shown below, although you should then keep cable lengths as short as possible. [. . . ] abbreviation of `panorama': controls levels sent to left and right outputs. the point at which a signal rises to its maximum instantaneous level, before falling back down again. It can also describe an equaliser response curve affecting only a band of frequencies, (like on a graphic equaliser), "peaking" at the centre of that band pan (pot) peaking 36 USER GUIDE SPECIFICATIONS TYPICAL SPECIFICATIONS Noise (22Hz-22kHz measurement bandwidth) Mic EIN @ max gain, 150 ohm source impedance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -128dBu Mix @ unity, faders down . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . <-85dBu Crosstalk (typ. @ 1kHz) Fader cut-off (rel +10 mark) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
