User manual SOUNDCRAFT FOUR BROCHURE

[. . . ] Small footprint. Series FOUR is a compact live sound mixer for front-of-house applications. Its high feature count combined with small footprint makes it ideal for budget-conscious touring applications, where the familiar control layout found on its big brother, the Series FIVE, will be highly appreciated. Partnered with the SM20 monitor console, the Series FOUR also provides a flexible audio mixing solution for live sound venues. The Series FOUR is available in four frame sizes providing 24, 32, 40 and 48 mono inputs into 8 group busses, 10 auxiliary busses and stereo and mono main mix busses. [. . . ] This return is ideally suited to cassette or CD music replay. The Mute button is controlled by the Mute Scene system and has a recessed `safe' switch, to protect it from muting during solo-in-place conditions. The Solo button provides mono PFL, stereo AFL or Solo-In-Place, depending on the mode selected at the master section. A rotary fader controls the level of the return, and the return can be selected for monitoring on phones even if it is muted. 7-SEGMENT DISPLAY AND UP/DOWN BUTTONS These allow the selection and display of the current snapshot number. The display flashes if the selected number does not match the currently active snapshot. STORE BUTTON Pressing this button stores the current mute settings to the snapshot number shown in the display. A confirm yes/no message is given. LEFT AND RIGHT LED METERS A pair of 16-segment LED peak meters are fitted at the top of the master module. These provide accurate metering of main mix outputs and soloed signals, even if the VU meterbridge is not fitted. RECALL BUTTON Pressing this button recalls the mute snapshot selected in the display. INPUT ASSIGN MODE BUTTONS Located on the Mute Master module, these two adjacent buttons are used in conjunction with the bi-colour illuminated assign switches next to the input faders, to display and set up VCA and Mute group assignments. The two buttons form a toggle switch, so that one is always active: Pressing the VCA button puts all the input VCA/Mute assign switches into VCA assign mode. The input assign switches illuminate in green when pressed, to show these assignments. Pressing the MUTE button puts all the input VCA/Mute assign switches into Mute group assign mode. The input assign switches illuminate in red when pressed to show the mute group assignments. PROCESSOR RESET BUTTON A recessed switch allows the mute control processor to be disabled in the unlikely event of a failure. Once disabled, all console mutes and faders are manually controllable. VCA and Mute group operation is not possible with the processor stopped, but the audio path will not be interrupted. CONSOLE LINKING All audio busses on the Series FOUR have balanced line level bus inputs, allowing the outputs of any other console to be easily connected. If full logic linking of VCAs and the solo controls to another Series FOUR is required, an RS232 port allows two consoles to be linked. ASSIGN SAFE SWITCH If the SAFE switch is pressed, the input assignment switches cannot be used to make or change assignments, but they can still be viewed. Toggling between VCA and Mute Group assign modes by pressing the VCA or MUTE Master Assign switches will display the current assignments in green or red respectively, on the input channels.
