Cperation MODULE IDENTIFICATION A sheet of labels is supplied Cut the FADE PAN name from the label sheet and stick it above the module s jack sockets at the rear of the MOTHER UNIT as shown in FIG 2 17 INSTALLATION To install the SF804 FADER PANNER module into the mother unit firstly make sure that the power is switched off Then locate the circuit card of the module squarely into the top and bottom guide slots at the desired position in the mother unit Gently slide it in If the module comes to a stop part of the way in gently move it from side to side so that the rear of the card is guided into the rear quide slots Now push it fully in If resistance is felt at this stage remove the module and check that that the wafer connector has not become damaged Once the module s front panel is located flush with the front of the mother unit fix it in place with special posidrive screws supplied with it The bushes into which the screws are fitted are initially unthreaded so when first used some resistance will be felt as the special screws cut a thread NOTE Make sure the screws go in straight DO NOT overtighten Use only the screws provided STUDIOMASTER PART No FX07018 CONNECTIONS The mother unit incorporates a signal routing system which routes the output from a module to the input of the module to its right The modules are therefore permanently connected in a daisy chain fashion If a signal is applied t
3. right the amount of shift depending on the amplitude of the trigger signal One could move for instance a keyboard sound in synchronism with the kick drum or move tomtoms in synchronism with the snare for some really fast drum work The Studiofex SF805 MODULATION SOURCE should be used for regular cyclic panning effects by patching one of its outputs to the fader panner KEY input Cyclic panning is achieved either in the LATCH mode using the RISE and FALL controls to determine the shift rate and stereo width or probably more favourably in the STAB mode using the SF805 s shape and depth controls to determine relative shift rates and stereo width respectively The OFFSET control can be put to good use here to centralise the panning effect It will be found that only a little depth is all that is needed to achieve quite a wide sounding stereo field Rather than always using over obvious hard image movement experiment with panning just a reverb or echo signal leaving the dry signal in the same place it can be very effective Another effect possible when using the Studiofex SF805 MODULATION SOURCE with the fader panner is signal amplitude controlled cyclic panning width by using the SF805 s keyed depth mode CROSS FADING Using both inputs in the PAN mode two sound sources can be cross faded either across the stereo field or by combining the outputs within the mixing console in mono One could for instance cross fa
