ÿþ SETTING UP THE DRUM PADS With the exception of the bass drum, all of the drum pads are the same. They contain a piezo-electric device, located in the centre of the drum pad, which outputs a voltage when stressed. The level of this voltage is dependant upon how much the component is stressed, and hence how hard the drum is struck. This varying voltage has a controlling effect on the synthesizer modules and this phenomenon is discussed more fully in the "playability" section of the manual. The difference with the bass drum is purely cosmetic. It is larger and has a mounting plate at the base for a pedal and a mounting on either side, into which the spurs should be located and angled to form a tri-pod with the drum perpendicular to the floor. Special care should be taken to tighten the mounting keys sufficiently to stop any rotation of the spurs. The pedal mounting plate will accept most conventional bass drum pedals, which are attached in the usual way. Dependant upon the configuration of your kit and the drum pads provided, a quantity of stands, mounting arms and brackets will be provided to support the drum pads. (Customers in certain countries please note that stands are not necessarily included). The pads should be set up around the bass drum in a suitable playing position for your particular requirements. Ensure that the mounting keys on the drum pads are finger tightened. Do not use pliers. When taking drums off their stands, loosen the mounting keys just sufficiently to allow the drum to slide easily off the mounting arm. Do not loosen the mounting key too far. The selector pad has its own universal mounting arm and is supplied with all kits. This should be employed to support the selector pad in an accessible position above the drums. All sixteen segments should be easy to reach with the tip of the stick. CONNECTING UP On the rear panel of the rack housing the electronics, there are twelve female XLR sockets labelled DRUM PAD INPUTS from 1 - 12. Each of these inputs corresponds to a channel in the rack where a module can be located. Viewing from the front of the rack, channel one is on the left and twelve on the right. The bass drum module is normally located in channel one and hence, the bass drum pad should be connected to the drum pad input channel I with the XLR cable provided. This operation should be repeated until all of the drum pads are connected to channels housing the relevant drum modules. If a hi hat module is included in the rack, the pedal provided should be connected to the input on the rear of the rack marked "Hi-Hat Ped" with one of the XLR cables. This input is located to the left of the drum pad inputs. The input to the left of this is marked "EXT. KIT SEL" and should be employed to connect the cable from the selector pad to the rack. At this stage, the SDS 7 is ready to be connected to a suitable amplification system. The question of a recommended system has no easy answer. Obviously such variables as the size of the venue and the type of music being played should affect your choice. By their definition, drum sounds are highly percussive and it is certainly desirable to amplify the SDS 7 at a level at least comparable to a conventional drum kit. Therefore, your chosen system should be capable of reproducing very dynamic sounds, spanning a broad frequency range. If you have previously been playing an amplified acoustic kit, the outputs from the SDS 7 can simply replace the drum mics. If the SDS 7 is being played live and you wish to utilise the facilities of an external mixing desk, the sockets marked "Audio Outputs", I - 12 should be utilised to connect each module with a separate channel of the desk. The output of each of these connections contains only the sound from the module in the relevant channel. This allows each drum sound to be equalised independently and is certainly the most desirable method of amplifying or recording the drums. If you have only a small stereo mixing desk and vacant channels are in short supply, the outputs marked left and right should be utilised to connect the SDS 7 to two channels of the desk. The drum sounds are panned automatically in these outputs and hence the pan controls on the mixing desk should be turned to left in the channel receiving the left output and right in the channel receiving the right. When used in this mode, the volume controls, which are the lower of the two controls located on the front of each module, should be employed to set the individual level of each drum. These volume controls also effect the level of the signal from the individual audio outputs. Whether using individual audio outputs or the stereo outputs for recording or playing live, the output marked "mono" can be used to simultaneously connect the SDS 7 to a separate amplifier for the purpose of monitoring. This is essential when playing on stage as the drum pads themselves produce no sound. The monitor system should be placed near the drummer and used at a suitable volume to allow all the musicians on the stage to hear the drums clearly. The relative level of each drum in the monitor mix will be the same as in the main mix, as the individual volume controls on the front of each module affect the level of all outputs.
