SYSTEM

Description

DESCRIPTION

GENERAL

The

DeltaMax™

System

consists

2-way

biamped,

high

performance

speaker

system

and

companion

electronic

controller.

The

DML-1122

and

DML-1152

are

full-range

loudspeaker

systems,

intended

for

high-level

sound

reinforce-

ment

touring

sound

and

permanent

installation

applications.

The

electronic-protection

technology

incorporated

into

the

DeltaMax™

System

allows

the

loudspeakers

operated

full

capacity

with

maximum

fidelity

and

reliability.

The

trapezoidal

cabinet

shape

allows

tight

cluster

designs,

enabling

maximum

mutual

coupling

and

single-point-source

arrays.

The

DML-1152

employs

15-inch

woofer

for

low-frequency

reproduction,

and

standard

2-inch

exit

DH1A

compression

driver,

The

DML-1122

utilizes

12-inch

woofer

and

1.3-inch

exit

modified

DH1A

high-frequency

driver.

Both

systems

use

flat-front,

constant-directivity,

high-frequency

horns

which

are

based

the

Electro-Voice

series

(Patent

#4,685,532)

and

are

geometrically

optimized

for

performance

from

1,250

20,000
