Ashly
mXa-1502.
Four zones of
mixing and DSP,
plus 2 x 150W
of power and
programmable
mic preamps…
made simple
and compact.
he mXa-1502 gives you multi-zone
T
music distribution, paging, soundmasking and automatic mixing for a
wide-range of environments.
Process 12 audio inputs into four different areas of a church, restaurant, school
or office/warehouse complex, etc., with
a single rack space device that includes
two Ashly-reliable 150-watt amplifiers
capable of driving 2,4 and 8-ohm as well
as 25, 70 and 100V loads.
ALso get a rich compliment of digital
signal processing, including routing,
auto-mixing, ducking, amplifier status
monitoring, event scheduling/triggering and more with Ashly AquaControl™
Software, that lets you navigate using
virtually any browser-enabled device.
The mXa-1502 provides total control
over four zones. For example: church
sanctuary, balcony fill, crying room and
foyer. Restaurant bar, main dining room,
patio and waiting area. Reception, offices, conference room and warehouse. A
big ballroom that gets partitioned into
smaller spaces.
