Description

The Alice Lansing DTS-640 is a three-way,

all-hom-loaded, factory-assembled system

with a coaxial mid/high section. The sys

tem can be configured as a iriamp system or

as a biamp system using the internal mid/

high passive crossover.*' This compact sys

tem features high sensitivity, high output ca

pability and poini-.source alignment, together

with excellent directivity control down to 800

Hz. The coverage at 1,000 Hz is 80° hori

zontal by 75° vertical, and the system’s nomi

nal coverage is 60° horizontal by 40° verti

cal. The horn-loaded bass section extends the

low-frequency response to below 60 Hz, or

lower if multiple units are used. The DTS-640

consists of two 381-mm (15-inch) high-

power, low-frequency drivers with a coaxial

mid-/high-frequency section consi.sting of a

high-efficiency 254-mm (10-inch) midrange

driver together with a 25.4 mm (I-in.) neody

mium compression driver. Both drivers uti

lize 60° X 40° constant-directivity horns.

Electrical connection to each driver is made

by large screw terminals able to accept up to

10-gauge wire, or two parallel. 8-pin female

Neulrik Speakon® connectors. The .system

should be used with the Altec Lansing 2400A

digital loudspeaker proces.sor. The recom

mended crossover frequencies arc 210 Hz

and 1.6 kHz. The enclosure is constructed

from 19-mm (0.75-in.) thick thoroughly

braced 14-ply birch plywood lined with

sound-absorbent glass wool. A complete

four-point hanging sy.siem is provided for

safe suspension of the DTS-640. The sys

tem may then be hung as a single unit or as

pan of a cluster. The finish of the enclosure

is textured black paint which can be painted

to complement any interior. The grille is con

structed from 16-gauge black, powder-

coated steel and is backed with a weather-

resistant foam.

The DTS-640 can be used individually or in

arrays to create compact, high-output and di

rectivity-controlled systems for use in

churche,s. auditoriums, hotels and civic centers.
