• 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-7.2.
• Connect your surround back speaker to the SURR BACK
SPEAKER terminals (see this page).
Connecting speakers
Caution:
Connect only speakers with an impedance between 4 and 16
Ω to
the DTR-7.2. If the impedance of even one speaker is between 4
and 6
Ω, be sure to set the speaker impedance setting
accordingly (see page 29).
• To prevent damage to circuitry,
never short-circuit the positive (+)
and negative (–) speaker wire.
NO!

Notes:
• When you are using only one speaker or when you wish to listen to
monaural (mono) sound, a single speaker should never be
connected in parallel to both the right and left-channel terminals
simultaneously.
