Ground stacking

In certain situations, indoors or outdoors, it may not be possible to fly any part of the system. In this case, the same general rules apply as for flown arrays. High packs should be kept well above head-height and angled carefully for even coverage. The integrated ‘A’ system flygear permits convenient ground stacking of both 890H mid-highs and 890L low cabinets. Small wood blocks (acoustic compensators) may be used to tilt mid-high cabinets downwards for the floor areas while the flygear is used to give predictable upwards angles, with the TS-890 tilt strap being used to lock the top cabinet in position. Various combinations of cabinets up to seven boxes high can be assembled to suit differing venue requirements.

In the example below, the first three cabinets are bass enclosures, stacked with the flygear loacked and with zero angle between them. These provide ground support by elevating the mid/high cabinets to a suitable height (the HF section of cabinet 4 is approximately 1.8 metres from the ground). A compensator is inserted between cabinets 3 and 4 in order to point the first mid/high slightly downwards onto the audience
