THE DELTAMAX" SYSTEM
Description
DESCRIPTION
GENERAL
The DeltaMax™ System consists of a 2-way biamped, high
performance speaker system and a companion electronic
controller. The DML-1122 and DML-1152 are full-range
loudspeaker systems, intended for high-level sound reinforce-
ment in touring sound and permanent installation applications.
The electronic-protection technology incorporated into the
DeltaMax™ System allows the loudspeakers to be operated at
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 a 15-inch woofer for low-frequency
reproduction, and a standard 2-inch exit DH1A compression
driver, The DML-1122 utilizes a 12-inch woofer and a 1.3-inch
exit modified DH1A high-frequency driver. Both systems use
flat-front, constant-directivity, high-frequency horns which are
based on the Electro-Voice HP series (Patent #4,685,532) and
are geometrically optimized for performance from 1,250 Hz to
20,000 Hz.
The DeltaMax™ flying versions, models DML-1122F and
DML-1152F, include three steel-reinforced aircraft-type pan
fittings on the top and bottom of the enclosures to facilitate the
hanging of multi-cabinet arrays. The DML-1122F/DML-1152F
Flying Manual is packed with each flying speaker system.
The electronic circuits are designed to provide optimum audio
performance, even when the audio drive level is increased for
maximum loudness. A high-performance compressor is con-
trolled by special speaker modeling circuits to provide speaker
excursion protection, speaker temperature protection, and
amplifier anti-clip limiting.
Optimum performance of these speakers can only be assured
when used with their dedicated electronics. Do not use with
other electronic crossovers and/or processors.
FEATURE SUMMARY
Fourth-order Linkwitz-Riley crossover filters provide smooth,
accurate response through the crossover region,
Special equalization circuits allow flat, wideband system
response
Sensing circuits for each driver control the compressor to
prevent voice coil overheating and amplifier clipping.
Voltage-clamp excursion protection does not alter program
dynamios.
Multi-time-constant compressor circuit with variable compres-
sion ratio reduces peak and average levels as necessary
while preserving relative program dynamics.
A connection to the control voltage is available through a
jack on the back panel. This allows precise gain tracking
when more than one unit is used.
The front panel display shows drive signal level and com-
pressor gain reduction. Sensing display for each sense
channel shows amplifier limit, excursion limit, and
temperature limit. When its limit is approached, each LED
lights yellow. i
Speaker system is trapezoidal for compact arrays. Flying
