Connecting speakers
placement angle or the polarity matching for speaker connections is
inappropriate, the audio phase displacement occurs. The audio phase
displacement may produce obscure sound image, unstable soundfield or
sound awkwardness.
Surround back speakers
• Place these speakers so that their
height is 3 feet (1 meter) higher than
that of the listener’s ears.
• (DTR-6.4 only) When using
surround back left and right
speakers, place them behind the
listener so that the angles between
the lines from each speaker to the
listener and a line straight back from
the listener are less than 30 degrees.
The positive speaker terminals on the DTR-6.4/5.4 are color coded
for easy identification. Attach the supplied speaker labels to the
speaker cables, and then match the colors on the speaker cables to
the corresponding terminals.
The speaker channels are colored as follows:
Front left speaker (+): White
Front right speaker (+): Red
Center speaker (+): Green
Surround left speaker (+): Blue
Surround right speaker (+):Grey
Surround back speaker (+):Brown
Zone 2 left speaker (+): White
Zone 2 right speaker (+): Red

DTR-6.4/5.4
After determining the layout of your speaker system, it is now
necessary to connect the speakers correctly to your DTR-6.4/5.4.
1. Strip away approx. 5/8 inch (15 mm)
of the wire insulation.
2. Twist the wire ends tightly together.
3. Unscrew the speaker terminal cap.
4. Insert the exposed wire end.
5. Screw down the speaker terminal
cap.
Caution:
• Be sure to connect the positive (+) and negative (–) cables for
the speakers properly. If they are mixed up, the left and right
signals will be reversed and the audio will sound unnatural.
• Do not connect more than one speaker cable to one speaker
terminal. Doing so may damage the DTR-6.4/5.4.
• Even if you are using only one speaker or listening to monaural
(mono) sound, never connect a single speaker in parallel to both
the right and left-channel terminals.
• To prevent damage to circuitry, never short-circuit the positive
(+) and negative (–) speaker wires.
Use the SUBWOOFER PRE OUT jack to connect a subwoofer with
a built-in power amplifier. If your subwoofer does not have a built-
in amplifier, connect an amplifier to the SUBWOOFER PRE OUT
jack and the subwoofer to the amplifier.
