[. . . ] Note: The initial settings should only be regarded as a starting point for your mix. It is important to remember that many factors affect the sound during a live performance, for instance the channel EQ settings or even the size of the audience!You are now ready to start building the mix and this should be done progressively, listening carefully for each component in the mix and watching the meters for any hint of overload. If this occurs, back off the appropriate Channel Fader slightly until the level is out of the red segments, or adjust the Mix Master Faders. This procedure will ensure that the mixer is set up correctly, with adequate headroom. If more amplification is needed, adjust the power amplifier level controls. Troubleshooting Po No Power Is the mains supply present?Check the mains fusing If only one of the power indicators is illuminated, consult your Soundcraft dealer No Wor orking Condenser Mic Not Working Is the 48V turned on?Is the mic cable a balanced 3-wire type? 14 Meters not showing any Meters not showing any signal Has the input gain been set correctly?(see above. ) Is the source connected to the appropriate input socket for the level of signal?Do you have something connecetd on the Inserts, and is that external device switched on?Are the Master faders set at max. , are input faders set high enough and is the channel routed to the output being monitored?Is the MUTE switch released on the relevant channels?Is the appropriate monitor select switch pressed?Is there a PFL/AFL pressed on another channel?

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 press the 48V switch down the socket provides a suitable powering voltage for professional condenser mics (this is also known as Phantom Power). ONLY connect condenser microphones with the 48V powering OFF (switch UP), and ONLY turn the 48V powering on or off with all output faders 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. Unplug any mics if you want to use the LINE Input. [. . . ] Take care to set up the input levels for best performance. When any PFL or AFL switch is pressed, the L & R meters automatically switch to show the selected PFL/AFL signal on both meters, in mono. 4 - MIX Pressing the Mix switch routes the post-fade Subgroup signals in pairs to the main Mix. Groups 1 & 3 are routed to Mix L, Groups 2 & 4 are routed to Mix R. MASTER FADERS 5 - MASTER FADERS The MASTER FADERS set the final level of the Subgroup and Mix L & R outputs. These should normally be set close to the `0' mark if the input GAIN settings have been correctly set, to give maximum travel on the faders for smoothest control. TO 6 - MIX TO C (mono) Pressing this switch routes the post-fade Mix L/R outputs to the C (mono) bus to create a separate mono mix to feed, for example, an induction loop or centre cluster. [. . . ]
