 description
The LR7 is a passive 2-way line-source loudspeaker
system. It is a true line-array system, to be used as
vertical array, either in stacked or flown configuration,
for both portable and permanent installations. Loaded
with the RBN401 pro-ribbon driver on a “Morpher” lens
(up to 94% frontal radiation!), the system features 120°
dispersion with seamless coverage, due to the ribbon’s
all-natural cylindrical (Isophasic) wavefront. Its transient
response and unusual high peak power handling
(800W/200mS) caters for an amazing intelligibility and
throw, while offering maximum “gain-before-feedback”
up to directly under the array.
The micro-sized design, combined with the weightsaving
all Neodymium drivers, makes the system very
easy to handle.
The “Morpher” is mounted in the “ALrad™” waveguide,
which utilizes the stiffness and heat transfer capabilities
of aluminium. Mounted on the RBN, the ALrad™ extends
the cooling surface for even further reducing powercompression
for increased SPL over time.
The SignalIntegritySensing™ pre-wiring ensures complete
cable/connector compensation between the LR7 and
ALC. Typical (short to medium throw) applications for
the LR7 include as compact main system for theatre, A/V
or corporate events where minimal sightline obstruction
is required, with exceptional sound reproduction. It is
available in 90° and 120° configuration.
In applications where extended bass response is
required, the LR7 can be combined with a pressurebass
or deep-sub system
For full system performance, we recommend using the
LR7 in combination with an ALC amplifier/controller.
Driven by the ALC, the LR7 delivers maximum sound
quality with inaudible (power and excursion) protection
(SDP circuit). All LR7 system presets are included in
the library of the Digital Drive Processor™; with which
also array-length and positioning (stacked/flown) can
be adjusted.
