JBL Professional CBT 70J-1

Immagini più grandi

Colonna Line Array a Due Vie con Constant Beamwidth Technology™ e Copertura Verticale Asimmetrica. Con staffa di montaggio migliorata per una maggiore flessibilità di puntamento e griglia più robusta.

Il CBT 70J-1, con Constant Beamwidth Technology™, rappresenta una svolta nella coerenza del controllo della dispersione: utilizza un complesso beam-forming a ritardo analogico e una modellazione dell'ampiezza per ottenere una copertura verticale superiore e uniforme, senza il restringimento verticale del fascio e i lobi fuori copertura tipici dei diffusori a colonna con fattore di forma rettilineo. (mostrato senza la griglia in dotazione)

Caratteristiche

Asymmetrical vertical coverage sends more sound toward far area of room to make front-toback sound levels more consistent.
Components: Sixteen 25 mm (1 in) soft dome tweeters and four 125 mm (5 in) high-power LF drivers,
arranged coaxially.
Patent-pending Constant Beamwidth Technology™ provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.
Vertical pattern coverage switchable between 45° for medium-throw coverage and 25° for
long-throw applications.
Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.
Dynamic SonicGuard™ overload protection of HF devices
Swivel (pan) / tilt wall bracket included.
