Bass-Array controller or lambda array is one of the latest technical creations of ATEIS International that fits perfectly in the 'Intelligent audio solution' range of products and has proven to be a real add-on to the third generation Messenger® line arrays.
The combination of Messenger line arrays and a Bass-Array offers the perfect solution for speech and musical performance in any difficult acoustic environment. By applying the same patent Messenger® technology to the Bass-Array, makes it the first array of its kind that carries bass frequencies over long distances and keep the signal deviation within 2dB over 100m.
Using a controlled power and frequency shading model, full directivity control and side-lobe suppression can be obtained. Upper and lower frequencies of this controlled directivity concept are defined by means of extending the total length for the lower frequencies by having multiple sources of which their acoustic centers are within 1/2 distance of the upper frequencies spaced. With a total length of 14m and only 8 cabinets, lobe steering and directivity control can be achieve down to 35Hz up to 400Hz.
