User manual SOUNDCRAFT SPIRIT LIVE V1

[. . . ] The FOLIO RAC PAC desk must only be connected through the Power Supply Unit supplied. The wires in the mains lead are coloured in accordance with the following code: Green and Yellow: Blue: Brown: Earth Neutral Live As the colours of the wires in the mains lead may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: · The wire which is coloured Green and Yellow must be connected to the terminal in the plug which is marked with the letter E or by the earth symbol. · The wire which is coloured Blue must be connected to the terminal in the plug which is marked with the letter N or coloured Black. · The wire which is coloured Brown must be connected to the terminal in the plug which is marked with the letter L or coloured Red. Ensure that these colour codings are followed carefully in the event of the plug being changed. The power supply contains no user-serviceable parts. [. . . ] The associated PEAK LED indicator normally warns when an excessively high signal level is present in the channel. The signal is sampled just after the EQ section and the LED will light approximately 4dB before clipping. This point is post-insert, and will therefore take into account the effect of any equipment connected to the Insert jack. 7 8 When the SOLO switch is pressed the LED lights continuously to show which channels are being monitored. 10 9 SPIRIT LIVE STEREO INPUT CHANNELs 11-14 These inputs accept 3-pole A gauge (TRS) jacks. Use these inputs for sources such as keyboards, drum machines, synths, tape machines or as returns from processing units. The inputs are BALANCED for low noise and immunity from interference, but you can use UNBALANCED sources by wiring up the jacks as shown in the "CONNECTIONS" section earlier in this manual, although you should then keep cable lengths as short as possible to minimise interference pick-up. If you wish to use the channel with a mono source, plugging into the Left jack automatically feeds the source to both sides of the channel. 1 2 1 INPUT +4/-10 Most professional equipment uses input and output levels of +4dBu, but semi-professional tape machines or hi-fi systems use a lower level of -10dBV. This switch allows you to match the sources connected to the Stereo input jacks to either standard, which is important to ensure the best possible sound quality. If you are not sure which input level is appropriate, start with the switch UP to select +4dBu. If you are unable to achieve an adequate signal level (even with the fader at maximium), press the switch in for -10dBV. 2 EQUALISATION HF EQ 3 Turn to the right to boost high (treble) frequencies, adding crispness to percussion from drum machines, synths and electronic instruments. Turn to the left to cut these frequencies, reducing hiss or excessive brilliance. The control has a shelving response giving 12dB of boost or cut at a fixed frequency of 12kHz. LF EQ 5-6 4 5 Turn to the right to boost low (bass) frequencies, adding extra punch to synths, guitars and drums. Returns A & B route to Groups 1 & 2, and Returns C & D route to Groups 3 & 4. The left return signal feeds the odd-numbered Group or Mix Left, while the right return signal feeds the even-numbered Group or Mix Right.

The Groups may feed external equipment directly through the ground compensated Group output jacks, or may be mixed together to the stereo Mix output (see below). The faders should normally be set close to the 0 mark if the input GAIN settings have been correctly set, giving plenty of control below the mark and additional gain in hand if required. 2 GROUPS TO MIX Pressing this switch routes all Groups to the main stereo Mix. Groups 1 & 3 feed Mix Left and Groups 2 & 4 feed Mix Right. 3 MIX FADER A stereo fader controls the output level of the stereo Mix. The Mix Left and Right signal paths have pre-fade INSERT points which provide a means of diverting the signal to an external processing unit such as a compressor or limiter. Inserting a jack into the insert breaks the signal path and allows the INSERT SEND (on the tip of the jack) to feed the input of the external unit and the INSERT RETURN (on the ring of the jack) to receive the corresponding output. Note that if the tip and ring of the jack are shorted together the signal path remains unbroken and the Insert may then be used as a way of tapping off the Mix signal before the fader. 4 2 TRACK (2TK) RETURN LEVEL The unbalanced 2TK return jacks are an ideal place to connect the playback of a tape machine, without using up any of the LINE inputs. This control sets the level of playback signal fed either to the MIX (when 2TK TO MIX is pressed) or the headphones or monitor output, when 2TK is pressed. When set fully clockwise the inputs will be matched to -10dBV sources, or will suit a +4dBu source with the LEVEL control at a lower setting. A mono source may be fed automatically to both left and right by plugging into the Left return jack only.

Any interference is picked up equally by the two wires, but out of phase resulting in cancellation of the interference signal. [. . . ]
