SoundCraft Spirit Monitor manual

The mixer is split into two sections. The Inputs receive, match and process individual source signals, and distributes them at precise mix levels to a choice of Monitor Outputs. The Mas- ter section provides monitoring of the audio signal at many points in the mixer, either on headphones or meters and pro- vides additional master control of talkback functions.

The Equaliser controls are the most flexible and potentially destructive feature of the mixer. They have a similar effect on the frequency response of the input channel as the tone con- trols on a hi-fi system, but with much greater precision, and allow particular characteristics of the input signal to be em- phasised or reduced. It is very important that you become familiar with the effect each control has on the sound and this is best achieved by spending time listening to the effect of each control on a well-known track played through the mixer.

Phase Reversal enables the operator to reverse the polarity of the signal entering the mixer, as a convenient way of checking for incorrect wiring or problems with microphone placement.

The Monitor Sends provide a way of routing the input sig- nals to a number of outputs, to create individual mixes for artists foldback or additional speaker outputs.

Pre-Fade-Listen(PFL)allows you to monitor the signal at many points in the mixer. Pressing any PFL switch places the signal at that particular point onto the headphones and the PFL meter, to check the quality of the signal or to pin-point problems. Using PFL will not affect the signals on the moni- tor outputs.

Each input channel and all outputs have an Insert ‘A’ gauge jack socket, which is a break point in the signal path. It allows the signal to be taken out of the mixer, through an external piece of equipment and then back into the mixer directly after its original exit point. The Insert point is normally bypassed by the ‘A’ gauge jack contacts, and is only brought into opera- tion when a plug is inserted. Typical uses would include Effects Processors, Limiters, additional Equalisers or Delay units.

The terms PRE and POST are often used in the context of In- serts, Equalisers and Channel Sends, and describe whether that facility is placed before (Pre) or after (Post) another par- ticular section. This is explained further in the detailed description of facilities.
