Vari In­tense- (VI) variable-intensity low distortion horn system. This design offers two funda­mental advantages. The variable horn throat impedance provides uniform sound pressure levels over the entire auditorium. Conven­tional 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 head­room, and radiates that wasted energy onto the ceiling and walls, thus producing reflec­tions that further degrade overall intelligi­bility and system clarity. The patented vari­able- intensity approach, on the other hand, compensates 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 the front, middle and the back of the room is achieved while substantially reducing re­flected energy and consequently greatly im­proving tonal quality and intelligibility. The advantages are twice the headroom and greatly improved fidelity.
The Variplex
TM
-XL is also unique in that its three-way design utilizes a bass/mid-bass/ high-frequency approach rather than a con­ventional bass mid-range/high-frequency design. This mid-bass/high-frequency ap­proach produces superior vocal clarity. Also incorporated into the Variplex Electro-Voice’s RMD

Low Frequency Assembly Instructions
Refer to Figures l and 2 for the following The Low Frequency Unit comes shipped as two pieces (2-TL606MXL's).
1. Turn one of the low frequency units up­side down and the other is right side up, ar­range as illustrated in figure 1.
2. Remove the isolation gasket stips from the low frequency accesory bag (shipped with the HPK-V ariplex
TM
-XL. Attach the strips to
the up-side down speaker as shown in figure 1.
3. Remove the locking brace the low fre­quency acessory bag and attach it to the back of the unit right side up.

4. Slide to two units together, with the backs almost touching and the front slightly appart. Engage the brace to the other speaker and tighten the bolt. Pull the front of the units together. Pass the 1/4-20 x 1 1/2 inch bolts through the holes opposite the T-nuts in each of the enclosures front baffle inside edge. (see figure 1) Tighten bolts unitl a 1/16 inch remains between the two enclosures.
5. Now that the Low frequency units are at­tached, the input panels can be connected. (See Figure 2 for referance) There are three wiring configurations possible. The speak­ers maybe wired in Series with one amp channel input or wired in Parallel with one amp channel input. Finally they may be wired seperately, each speaker on one amp channel. (NOTE: Use red jumper plugs
but, do not us wire jumpers between J1 and J2 when using this particular configu­ration.) Series wiring configuration: Connect J1 to
J1 and J2 to J2, using supplied wire jumper.
Select the supplied white jumper plug and the yellow jumper plug. The white jumper plug is to be installed on the speaker which has T1 and T2 connected to the amplifier source. The yellow jumper is installed on the other speaker, for a nominal impedance of 12 ohms. Parallel wiring configuration: Connect J1 to J1 and J2 to J2, using supplied wire jumper. Select the two supplied red jumper plugs and install one in each of the input panels. The amplifier source may be connected to either input panel at T1 and T2, for a nomi­nal impedance of 2.8 ohms.
Seperate wiring configuration: Do not con- nect J1 to J1 amd J2 to J2. Select the two
supplied red jumper plugs and install one in each of the input panels. The individual am­plifier channels may be connected to each of the input panels at T1 and T2 for indivdual nominal impedances of 6 ohms.

Mid/HI Frequency Assembly Instructions
Refer to Figures 3 for the following steps.
1. Remove four screws on top of the Low frequency unit (see figure 3), two from each of theTL606MXL enclosures Two of the screws are 1 3/4" and will be replaced in the same holes.
2. Set the mid/high sub-assembly on top of the two TL606MXL's align the empty holes on both TI606MXLs with the three slots of the mid/high sub-assembly mounting board. Reinstall the screws previously removed , be­ing sure to install the longer two screws in the back slot under the adjustment bracket.
3. Adjust the horizontal position by rotat­ing the HPK-Variplex
Variplex™ XL 3-Way Screen System
TM
-XL and securely
tighten all the bolts so that the mid/high sub-
assembly does not inadvertently rotate.
4. Now loosen the vertical adjustment bolts (see figure 3) just enough so the adjustment guides will slide within the adjustment slot and the bracket is allowed pivot. Adjust the vertical angle, by tilting the mid/high sub­assembly,
which will slide the adjustment
bolts along the slot as shown in figure 3.
5. The aiming point of the mid/high sub­assembly horn seperates the Mid-frequency section from the Hi-frequency section, (see figure 7). The system is approximately po­sitioned 2/3 the way up the screen (see fig­ure 7), then tilted vertically to align the aim­ing point two feet above the head of the per­son sitting in the last seat of the theater. (See figure 7) Tighten the vertical adjustment bolts, so that the mid/high sub-assembly does not inadvertently tilt.
Figure 3—Mounting the HPK-VARIPLEXTM-XL (pre-assembled mid/high unit)
Note:Additional tilting may be necessary depending on the slope of the seating area. Do not tilt the aiming point below 2ft. above the last person sitting in the last seat of the theater . Sound pressur e levels drop off drastically above zero on axis.
Crossover Equalization
The Electro-Voice Dx38 digital electronic crossover system may be used to crossover equilize and set time delay for the VariplexTM-XL. Figure 6 is a typical trans­fer curve based on the indivdual frequency responses of its components as shown in fig­ure 4. Further data on these setting may be obtained by contacting Electro-V oice for in­formation on specific Dx38 presets.

The measurement was made with a swept sine-wave signal, 4 volts at 500 Hz, in an anechoic (echoless) environment. The micro­phone was at a distance of 3.048m (10 ft), on an axis with the aiming pointof the Mid/ Hi-frequency unit. Figure 5 shows the fre­quency response of the individual sections
