Connecting Speakers; Using The Speaker Cable Labels - Integra DTR-7.4 Instruction Manual

Connecting Speakers

After determining the layout of your speaker system, it
is now necessary to connect the speakers correctly to
your DTR-7.4.
You can also use banana plugs/connectors.
Caution:
Connect only speakers with an impedance between 4 and
16 Ω to the DTR-7.4. If the impedance of even one
speaker is between 4 and 6 Ω, be sure to set the speaker
impedance setting accordingly (See page 30).
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 damage to circuitry,
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.
Use the PRE OUT
SUBWOOFER 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 PRE OUT
SUBWOOFER jack and the
subwoofer to the amplifier.

• Do not connect more than one speaker cable to one
speaker terminal. Doing so may damage the DTR-7.4.
• Connect either your surround back speakers or the
speakers you will be using in the remote zone (Zone
2) to the SURR BACK/ZONE 2 SPEAKERS
terminals (See page 66).

Using the Speaker Cable Labels

The positive speaker terminals on the DTR-7.4 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.
