Connecting the Mythos XTR-50
The wire connection method used on the Mythos XTR-50 is
different than most speakers so please read these instructions!
(NOTE: if you are using the table stands, you should pass the wire through
the wire channels before attaching the green speaker wire connector.)
1. In the accessories plastic bag you will find a small green plastic
connector as shown in Figure 1.
2. Strip 1⁄ 2 inch (12 mm) of insulation from each conductor of the
speaker wire to expose the bare metal and twist each of the
individual conductors into single un-frayed strands.
3. Use a small jewelers screwdriver to loosen the screws on the
connector just enough to allow the wire ends to fit in
the holes. [Figure 1]
4. Slip the wire ends into the holes and tighten the screws until the
wire is firmly attached to the connector. (NOTE: if you are using
the table stands, you should pass the wire through the wire
channels before attaching the wire connector.)

6. Connect a single RCA cable from the "SUB OUT" of your receiver
to the LFE input of the subwoofer (not included). [Figure 3] This
connecting method bypasses the subwoofer's internal "crossover"
or low pass filter and relies on the crossover filter built into
your receiver.
7. See page 4 for instructions on Speaker Set Up in your
surround receiver.
If you intend to place the Mythos XTR-50 on a TV or shelf
in a horizontal orientation, see page 3.

Note that one of the terminals is marked
with "+" and the other is marked with "-".
Make certain that you connect the wire
from the red (+) terminal of your amplifier
or receiver to the "+" terminal on your
speaker and the wire from the black (-)
terminal of your amplifier or receiver to the
"-" terminal on your speaker. Most speaker
wire has some indicator (such as color-
coding, ribbing or writing) on one of the
two conductors to help you maintain
consistency. It is essential to connect both
speakers to the amplifier in the same way
(in phase). If you experience a lack of bass
or poor surround effect, it is likely that one
or more of the channels is connected in
incorrect polarity and needs to be rewired.
Pay closer attention to connect
positive to positive and negative to
negative on all channels.
5. Gently push the male
connector with the wire into
the female receptacle on the
speaker. The connector is
designed so that it can
only go in one way with the
correct orientation of positive
and negative pins. [Figure 2]

Wall Mounting the Mythos XTR-50
• We recommend that wall-mounting of speakers be performed by
professional installers or by those skilled in the use of power tools
and the knowledge of building codes and structural issues.
• We recommend that you determine a suitable location for your
speaker installation, and that you complete all wiring (especially
"hidden" in-wall wiring) before mounting the brackets to your walls.
• Mythos wall-mount brackets are not suitable for ceiling mounting.
The Mythos XTR-50 loudspeaker comes with a wall-mounting
bracket that can make mounting easier but in most cases the
bracket is not necessary to wall-mount the speaker. The supplied
bracket may be necessary when mounting the speaker to a full-
motion or tilting TV wall-mount. You may choose to use the
supplied wall-mount bracket if you want the speaker to protrude a
bit more from the wall (total depth without the bracket is 1.5 inches
[38mm] and 1.6 inches [40mm] with the bracket). The bracket is
padded with foam that may be useful for damping rattles or
vibrations between speaker and wall surface.
Follow these directions for wall mounting the speaker without
using the bracket.
1. Two cardboard mounting templates are supplied, one for
horizontal speaker orientation and the other for vertical. Be sure
to use the correct template. Hold the cardboard template in the
intended location. Make sure the speaker clears the ceiling,
adjacent walls, corners, beams, lighting fixtures and door/window
frames. Leave at least 1" (25 mm) above or to the side of the speaker
location to allow the speaker to slide onto the screws.
2. Make sure the center of the template is centered with the TV
screen's center points.
3. When mounting the speaker horizontally, use a bubble level to
make sure the template is level.
4. When mounting the speaker vertically, use a plumb line to find
perfect vertical. If the TV is off-level or off-plumb, the speaker will
look better if it is off-level or plumb in exactly the same way as the TV.
5. Use push pins to secure the template to the wall.
6. Make pencil marks in the holes labeled "Pilot Hole (for mounting
without bracket)"; remove the template.
