CA-28A / CA-28B<br />

El recinto CA-28A es un módulo autoamplificado <strong>de</strong> array<br />

compacto <strong>de</strong> dos vías, diseñado para ser empleado acompañado<br />

<strong>de</strong> otras unida<strong>de</strong>s. Ligero y <strong>de</strong> fácil manejo, su<br />

recinto trapezoidal incorpora un sistema <strong>de</strong> colgado que<br />

permite también apilarlo <strong>de</strong> forma rápida, segura y<br />

sencilla. El mecanismo <strong>de</strong> angulación situado en la parte<br />

posterior <strong>de</strong>l recinto mantiene unidos los frentes,<br />

in<strong>de</strong>pendientemente <strong>de</strong>l ángulo entre módulos CA-28A.<br />

Esto permite crear arrays "sin huecos" en el plano frontal,<br />

mejorando las prestaciones <strong>de</strong>l sistema.<br />

Dos altavoces <strong>de</strong> 8" dispuestos en V, mo<strong>de</strong>lo 8MN16, con<br />

bobina <strong>de</strong> 62 mm (2.5") y núcleo magnético <strong>de</strong> neodimio<br />

<strong>de</strong> alto rendimiento son utilizados para la reproducción <strong>de</strong><br />

las frecuencias medias. Diseñados para ofrecer gran<br />

robustez y poco peso, su eficiente sistema <strong>de</strong> evacuación<br />

<strong>de</strong> calor Total Air Flux (T.A.F.) minimiza la compresión <strong>de</strong><br />

potencia.<br />

Para las frecuencias altas, incorpora un motor <strong>de</strong> compresión<br />

M-10N, con bobina <strong>de</strong> 73 mm (3"), núcleo magnético<br />

<strong>de</strong> neodimio, y salida <strong>de</strong> 1.5". El motor se encuentra acoplado<br />

a la guía <strong>de</strong> onda plana SERPIS, y a un difusor<br />

BP-906, <strong>de</strong> estrecha cobertura vertical. El dispositivo<br />

SERPIS diseñado por D.A.S. Audio genera un frente <strong>de</strong><br />

onda isofásica plana sin la existencia <strong>de</strong> interferencias en<br />

la sección <strong>de</strong> altas frecuencias.<br />

El sistema CA-28B es una versión no-amplificada <strong>de</strong> dos<br />

vías diseñada para su uso con amplificación externa.<br />

The CA-28A is a self-powered, bi-amplified, two-way compact<br />

line array module <strong>de</strong>signed for use in multi-box<br />

arrays. The easily portable and rugged trapezoidal<br />

enclosure incorporates all the rigging hardware and fittings<br />

nee<strong>de</strong>d to join one box to another. The CA-28A's<br />

trapezoidal shape and rear located splay angle adjusters<br />

keep the front spacing between adjacent elements the<br />

same, providing the array with a "seamless" front baffle,<br />

for improved array performance.<br />

Two purpose-built 8MN16, 8" cone transducers incorporating<br />

neodymium magnetic assemblies and 2.5" (62 mm)<br />

voice coils are used for mid frequency reproduction. These<br />

rugged, yet lightweight components provi<strong>de</strong> high output<br />

and the unique Total Air Flux (T.A.F.) cooling schemes<br />

minimize power compression resulting from voice-coil heat<br />

buildup.<br />

High frequency reproduction is handled by the outstanding<br />

M-10N medium format compression driver which uses a 3"<br />

(73 mm) titanium diaphragm, copper clad aluminum EFW<br />

voice coil and a 1.5" exit throat. This high efficiency, low<br />

distortion unit incorporates a neodymium magnet structure<br />

and is coupled to a SERPIShigh frequency plane wave<br />

generator. The D.A.S. <strong>de</strong>signed <strong>de</strong>vice ensures accurate<br />

high-frequency summing and the generation of a flat,<br />

isophasic wave front for the high frequency section.<br />

The CA-28B is a non-powered two-way active version<br />

<strong>de</strong>signed for use with external amplification.
