Descripción - Description
[ES] MA 12 es un sistema multifunción autoamplificado de dos vías equipado con un altavoz de 12" en un
recinto sintonizado. La sección de agudos cuenta con un motor de compresión de 1" acoplado a un difusor
rotable con cobertura 60x40. MA 12 incorpora un módulo de amplificación GT 1.2 H, el cual ofrece la
ventaja de amplificar la propia unidad y otra unidad M 12 pasiva en modo esclavo. Perfecto para ser
utilizado como P.A, frontfill y sidefill con o sin subwoofer, como sistema portátil o instalación permanente,
también está diseñado para ser utilizado como monitor de escenario.
[EN] MA 12 is a 2-way multipurpose self-powered system equipped with one (1) speaker of 12" in a tuned
enclosure. The HF section has one (1) compression driver of 1”, coupled to one (1) rotating diffuser of
60x40. MA 12 incorporates an amplifier module GT 1.2 H, which offers the advantage of amplify itself and
another passive unit M 12 in slave mode. It is perfect to be used as P.A, frontfill and sidefill with or without
subwoofer, as portable system or permanent installation, it has been also designed to be used as stage
monitor. Excellent as sonorous reinforcement for all our systems.

MOUNTING INFORMATION
*T-S parameters are measured after an exercise period
using a preconditioning power test. The measurements
are carried out with a velocity-current laser transducer
and will reflect the long term parameters (once the
loudspeaker has been working for a short period of
time).
** The Xmax is calculated as (Lvc - Hag)/2 + (Hag/3,5),
where Lvc is the voice coil length and Hag is the air gap
height.
