User manual SOUNDCRAFT SPIRIT FOLIO SI

[. . . ] Above all, remember that your SPIRIT mixer is designed to extend your creativity. The more that you explore the controls and the effect they have on the sound output, the more you will appreciate how you can influence and enhance the final sound. SAFETY PRECAUTIONS For your own safety and to avoid invalidation of the warranty please read this section carefully. The FOLIO 4 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. [. . . ] DO NOT use unbalanced sources with the phantom power switched on. The voltage on pins 2 & 3 of the XLR connector may cause serious damage. Unplug any mics if you want to use the corresponding LINE Input to avoid the load presented by the mic from affecting the Line Input gain. The input level is set using the GAIN knob. 2. Hot(+ve) Link 3 to 1 Balanced Mic Input - XLR 2. Screen Balanced Input Unbalanced Mic Input - XLR 1. Screen 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 guitars. The input is BALANCED for low noise and immunity from interference, 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 to minimise interference pick-up on the cable. Unplug anything in the MIC input if you want to use this socket. Set the input level using the GAIN knob. Unbalanced Input 3-Pole Jack Balanced Hot (+ve) Cold (-ve) Gnd/Screen Tip Ring Sleeve Unbalanced Signal Gnd/Screen Gnd/Screen GAIN This knob sets how much of the source signal is sent to the rest of the mixer. Set the knob to the centre-detented position when not required. EQ SWITCH The EQ switch bypasses the Equalisation section when released and places it into the channel path when pressed. It would typically be used for simple comparison of the equalised and unequalised signal. AUXILIARY SENDS SPIRIT FOLIO SI 14 These controls route the input channel signal to any one or more of eight Auxiliary busses. These combine the sends from each channel, mixing them to separate outputs on the rear of the mixer. Since they are independent of the main outputs they can provide additional sources for foldback, effects processors or extra loudspeaker `fills'. The controls are specially chosen to give a particularly smooth control range at the lower end of the scale where it is most needed - quite unique on a mixer of this type. Leave the knobs turned anticlockwise when not in use. AUX SEND 1 & 2 These sends are always PRE-FADE, PRE EQ and are unaffected by the ON switch. They would typically be used for Foldback or Monitor feeds, for which it is important that the send should be independent of the fader so that, for instance, the mix to artists headphones is not affected by changes in fader level. AUX SEND 3 This send can be pre-fade, pre-EQ and be used in the same way as Aux Sends 1 & 2 for Foldback or as a Monitor feed, but for Effects it is more appropriate for the Aux Send to fade up and down with the fader (POST-FADE). A Master Section AUX3 PRE switch allows you to switch all channel Aux 3 sends from pre- to post-fade across the whole mixer as required. The send is unaffected by the position of the ON switch if the master section Aux 3 PRE is pressed. AUX SENDS 4-8 These are always POST-FADE and would normally be used to drive effects processing units which are fed back into the mixer and which must fade out with the input channel. Aux 4 is an individual mono send, while the 5/6 STE knob feeds the channel signal via the PAN control (see below) as a stereo pair to either Aux outputs 5 & 6 or, with the 7-8 switch pressed, to Aux outputs 7 & 8. PAN This control sets the amount of the channel signal feeding the Right and Left MIX or GROUP outputs, allowing you to move the source smoothly across the stereo image. Rotation fully anticlockwise feeds the signal solely to the Left mix bus, Group 1 or Group 3, while rotation clockwise sweeps the image to the right bus, Group 2 or Group 4. ON SWITCH The ON switch enables all post-fade outputs from the channel when pressed. [. . . ] a ratio of two voltages or signal levels, expressed by the equation dB=20Log10 (V1/V2). Adding the suffix 'u' denotes the ratio is relative to 0. 775V RMS and`V' expresses the ratio relative to 1V RMS. (direct injection) the practice of connecting an electric musical instrument directly to the input of the mixing console, rather than to an amplifier and loudspeaker which is covered by a microphone feeding the console. the use of devices to alter or process the sound to add special effects e. g.
