Intended Use
This speaker box is exclusively meant for the reproduction of audio signals according to instructions
and specications given in this manual. We‘re not liable for any damage caused by unintended use.
Safety Instructions
For your own safety you must read through this chapter at rst completely, before you connect the device!
Never submerse the speaker box in water. Liquid getting into the box will risk a short circuit and will be haz-•
ardous.
Do not expose the speaker box to direct precipitation and never use it in a damp or wet environment. This •
speaker box was developed for indoor use only. Do not use it outdoors.
Do not place the speaker box in locations that are subject to high temperatures, direct sunlight, or excessive •
dust.
Never operate the speaker box in the vicinity of heat sources such as cookers, heating elements or other •
heat producing installations.
Keep children away from the speaker box. Children frequently underestimate the dangers of electrical de-•
vices.
Keep sufcient distance from the speaker box when operated with high volume level. Listening to •
music with high sound pressure level may cause permanent damage to your hearing!
Flying and installation of this speaker cabinet must be carried out by suitably qualied personnel following •
the approved safety standards.
Do not attempt to clean the plastic enclosure with solvents or petrochemical based cleaners.•
Do not place objects which are sources of heat on the speaker cabinet such as lighting equipment or smoke •
machines.
Do not stack the speaker cabinet in a manner that could cause injury should a cabinet become dislodged.•
Before connecting or operating this speaker box, please study and follow the instruction manuals of all de-•
vices connected to the box, paying particular attention to the operating precautions and wiring procedure.
Features
LA-210 is a line array loudspeaker for medium scale sound reinforcement.
Using the LA-210 Flying frame it can be own in vertical columns with up to 12 cabinets giving a 90° constant
directivity dispersion pattern in the horizontal plane.
The LA-210 is a 2-way design housing 2 x 10” neodymium kapton LF drivers and two 2 x 4” x 1” (101.6 x 25.4
mm) neodymium Kapton compression drivers. The cylindrical wave segments of each cabinet will couple
without gaps and sum up coherently. Splay angles between adjacent cabinets can be set in the range from 0°
to 5° in half degree steps.
All components are arranged symmetrically around the centre axis of the cabinet to produce a perfect
symmetrical dispersion pattern. This setup allows a very smooth crossover design with well dened overlap
of adjacent frequency bands resulting in a very consistent and accurate horizontal dispersion. Due to dipolar
arrangement of the low drivers the nominal dispersion of 90° is maintained down to 200Hz.
The frequency response of LA-210 extends from 100Hz - 19kHz.
The LA-210 cabinet is made of plywood and has an impact and weather resistant polyurethane nish. The
front of the loudspeaker cabinet is protected by a rigid metal grill. There are two handles designed on the side
panels.

HORIZONTAL DIRECTIVITY
The data of LA-210 horizontal directivity were collected by testing the speaker system in a big anechoic
chamber.
The scale is stepped by 6dB increment.

VERTICAL DIRECTIVITY
The data of LA-210 vertical directivity were collected by testing the speaker system in a big anechoic chamber.
The scale is stepped by 6dB increment.

Installation
Three points suspension system of LA-210:
The ying system includes LA-210 ying metal frame, front and back rigging parts and pins. •
Rear rigging part has been assembled onto cabinet to make the vertical angle (between each unit) easily •
adjustable and more convenient.
LA-210 ying frame is weld steel frame, we can hang up many LA-210 speakers at the same time.•
