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 , be-
ing sure to install the longer two screws in
the back slot under the adjustment bracket.
3. Adjust the horizontal position by rotat-
ing the HPK-Variplex

-XL and securely
tighten all the bolts so that the mid/high sub-

above the last person sitting in the last seat
of the theater. Sound pressure 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

-XL. Figure 6 is a typical trans-
fer curve based on the indivdual frequency
responses of its components as shown in fig-
ure 4. Further data on these setting may be
obtained by contacting Electro-Voice for in-
formation on specific Dx38 presets.

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 sub-
assembly,
which will slide the adjustment
bolts along the slot as shown in figure 3.
5. The aiming point of the mid/high sub-
assembly horn seperates the Mid-frequency
section from the Hi-frequency section, (see
figure 7). The system is approximately po-
sitioned 2/3 the way up the screen (see fig-
ure 7), then tilted vertically to align the aim-
ing point two feet above the head of the per-
son 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.
