The Electro-Voice Variplex
specifically for use in ultrahigh-fidelity
cinema applications. The system offers
Electro-Voice patented technology. The
Variplex TM
-B is a three-way configuration
that addresses many performance issues not
addressed in other three-way designs. The
Variplex TM -B employs Electro-Voice's pat-
ented 1 Vari Intense ® (VI) variable-intensity
horn system. This design offers two funda-
mental advantages. The variable horn throat
impedance provides uniform sound pressure
levels over the entire auditorium. Conven-
tional horn systems attempt to do the same
by aiming the center of the high-frequency/
mid-frequency horn toward the rear of the
room. This conventional approach wastes
fully one-half of the system energy and head-
room, and radiates wasted energy onto the
ceiling and walls, thus producing reflections
that further degrade overall intelligibility and
system clarity. The patented variable- inten-
sity approach, on the other hand, compen-
sates for the natural phenomenon of sound
reduction with distance and produces

extremely uniform coverage for the entire
seating area. The same level of fidelity in

reflected energy and consequently greatly
improving tonal quality and intelligibility.
The advantages are twice the headroom and
greatly improved fidelity.
The Variplex
three-way design utilizes a bass/mid-bass/
high-frequency approach rather than a con-
ventional
design. This mid-bass/high-frequency ap-
proach produces superior vocal clarity. Also

form the job they were originally intended
to perform, that being room equalization and
correction of the spectral characteristics
inherent in the tranducers themselves. Prior
designs have frequently attempted to "re-
solve" loudspeaker design issues with elec-
trical equalizers. RMD

refines system clarity.

• Vari-Intense ® Technology for
smooth, even coverage
• Passive mid/high design allows
for biamped operation
• Compact design for limited
behind-the-screen space
• Ring-Mode Decoupling (RMD
provides greater Intelligibility
• Digital Dynamics Capable
• Factory pre-assembled mid/

The compact design of the Variplex
the system to be used even when behind-the-
screen space is limited. Compact design can
also provide a cost savings by allowing the
addition of extra seating.
The unique performance enhancements and
system capabilities are ideally suited to the
high dynamic-range demands of digital ma-
terial. When the Variplex TM -B is used in con-
junction with Electro-Voice's subwoofers, the
combination defines a new standard for
realism and total system accuracy.
Mounting Instructions
Refer to Figures l and 2 for the following
steps.
1. Remove five screws on top of the
TL606DMT (see figure 2), the two far-
thest from the front of the enclosure are 1
3/4" and will be needed be replaced in
the same holes.
2. Set the mid/high subassembly on top of
the TL606DMT align the empty holes on
the TL606DMT with the three slots and
center pivot hole of the mid/high subas-
sembly mounting board. Reinstall the
screws previously removed, being sure
to install the longer two screws in the
