LINA Arrayed Loudspeakers and Dimensions
The LINA™ compact linear line array loudspeaker excels in array performance while providing exceptional high frequency headroom, phase coherence, and consistent coverage. Its light weight and small size are ideal for venues that require a low-profile, high-power, curvilinear array system with exceptional fidelity, such as small theaters, theme parks, houses of worship, and AV systems.
Single cabinet or short stack implementations of LINA are also well-suited for front-fill and under-balcony applications that must attain precise high-frequency vertical coverage. In addition to standalone implementations, LINA is useful in LEOPARD™ systems as a supplemental fill loudspeaker.
LINA evolved from the highly successful MINA™ loudspeaker, now optimized using the state-of-the-art technology that made the LEO® family an award-winning product line. LINA delivers the same signature and advantages of self-powered design, linear response, and precise directional control. Like LEOPARD, LINA loudspeakers offer Native Mode, a configuration optimized to yield excellent system performance right out of the box with minimal external processing.
LINA features an innovative, newly designed, highly efficient class D amplifier that reproduces any sound source with linearity over a wide dynamic range, from speech and classical music to rock and EDM. LINA faithfully reproduces audio with tremendous power, superior intelligibility, and extremely low distortion.
Drive LINA systems with Meyer Sound’s Galileo® GALAXY Network Platform, which provides 24 bit, 96 kHz audio, matrix routing, alignment, and processing for array components. Using the Meyer Sound MDM-832 distribution module to route AC power, balanced audio, and optional RMS™ module signals to multiple LINA loudspeakers further enhances the portability and ease of configuring a system.
For low-frequency extension, LINA pairs with Meyer Sound’s 750-LFC low-frequency control element, which can be flown in a LINA array without transition hardware. Like LINA, the 750-LFC is efficient and versatile, with an excellent power-to-size ratio. Applications that require more low-frequency headroom can use Meyer Sound’s 900-LFC, which also integrates with LINA systems.
LINA includes Meyer Sound’s QuickFly® rigging with captive GuideALinks™ that can create splay angles from 1 to 11 degrees. A range of available rigging accessories make LINA a versatile solution for a variety of applications. To design entire LINA family systems, use Meyer Sound’s MAPP™ System Design Tool, as it effectively anticipates system SPL and coverage requirements. This useful tool also helps verify rigging load ratings.
Meyer Sound coats the premium multi-ply birch LINA cabinet with a slightly textured black finish. Other options include weather protection and custom color finishes for fixed installations and applications with specific cosmetic requirements.

Notes
Loudspeaker system predictions for coverage and SPL are available in Meyer Sound’s MAPP System Design Tool.
Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.
Maximum SPL is the peak measured in free-field at 4 m referred to 1 m using noise.
Linear Peak SPL is measured in free-field at 4 m referred to 1 m. Loudspeaker SPL compression measured with M-noise at the onset of limiting, 2-hour duration, and 50°C ambient temperature is <2 dB.
M-noise is a full bandwidth, (10Hz–22.5kHz) test signal developed by Meyer Sound to better measure the loudspeaker’s music performance. It has a constant instantaneous peak level in octave bands, a crest factor that increases with frequency, and a full bandwidth Peak to RMS ratio of 18 dB.
Pink noise is a full bandwidth test signal with Peak to RMS ratio of 12.5 dB.
B-noise is a Meyer Sound test signal used to ensure measurements reflect system behavior when reproducing the most common input spectrum, and to verify there is still headroom over pink noise.
Pins 4 and 5 (RMS) only included with XLR 5-pin connector that accommodates both balanced audio and RMS signals.
Peak power based on the maximum unclipped peak voltage the amplifier will produce into the nominal load impedance.
AC power cabling must be of sufficient gauge so that under burst current rms conditions, cable transmission losses do not cause the loudspeaker’s voltage to drop below the specified operating range.
