Line Array Enclosure

1x 12″ Bass Driver + 2x 6″ Mid Driver + ISOPHASIC HF Device – 3860 Watts Program

The TLA312 Blackbird Line Array Loudspeaker is a highly refined compact three way system. Low Frequencies are reproduced with an extended range 12” transducer. The Mid Frequency system utilises two high efficiency 6.5” devices. The all important High Frequencies are handled by an ISOPHASIC H.F. Aperture providing superb response and precise pattern control. Horizontal dispersion is user adjustable, offering 60º, 90º, 120º or 150º options, including asymmetric horizontal dispersion patterns. Vertical Dispersion is controlled by array size. All transducers feature neodymium motors providing high performance with reduced weight.

The proprietary Blackbird Flying Hardware system is an integral cabinet component and is supplied as standard. Inter cabinet angles are easily and accurately adjusted in 0.5º increments, from 0º to 5º, with the pivot point located at the cabinet front to maintain the integrity of the H.F. Aperture.

The flying system is designed so that all parts are captive to the cabinet frame with nothing that can become lost in transit.

The flying frame is suited to either flown or ground stack applications.

Acoustic Technologies Line Array Prediction Software enables highly accurate prediction of multi-cabinet array configurations and SPL coverage prior to flying the system.

The cabinets are finished in black AcoustiCoate polymer with powder coated grilles and are fitted with dual NL Speakon connectors with loop thru connections for Sub Bass provided.

The TLA312 Blackbird Line Array System is ideal for compact touring systems, outdoor music festivals and sporting events, corporate presentations and a wide range of in-house sound reinforcement applications including houses of worship, theatres and showrooms.
