Connecting Speakers
After determining the layout of your speaker system, it
is now necessary to connect the speakers correctly to
your DTR-10.5.
For the USA and Canadian models, you can also use
banana plugs/connectors.
You can connect speakers with an impedance of between
4 and 16 ohms. If the impedance of any of the connected
speakers is 4 ohms or more, but less than 6 ohms, be sure
to set the Speaker Impedance to “4 ohms” (see page 89).
If you use speakers with a lower impedance, and use the
amplifier at high volume levels for a long period of time,
the built-in protection circuit may be activated.
Notes:
• 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 circuitry damage, never
short-circuit the positive (+) and
negative (–) speaker wire.
• 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-10.5.
Connecting the Speaker Cable
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. Tighten speaker terminal cap.
Tip:
The terminal wrench that
comes with this unit is a
useful tool for tightening/
loosening the speaker
terminal cap.
Attaching the Speaker Labels
The positive speaker terminals on the DTR-10.5 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 left speaker (+): Brown
Surround back right speaker (+): Tan
