When connecting one surround back speaker
1. Connect the speaker to the SURROUND BACK SPEAKER
terminals on the DTR-6.4/5.4.
2. (DTR-6.4 only) Set the “Hardware Config”
→ “b. Surr Back”
setting to “1 ch” (see page 32).
Tip:
When you use one surround back speaker and want to connect it
through power amplifier, use the SURR BACK PRE OUT L
terminal. In this case, the setting for the “b. Surr Back” should be
set to “1ch”.
When connecting two surround back speakers (DTR-6.4
only)
1. Make connections between the SURR BACK PRE OUT L/R
terminals on the DTR-6.4 and the audio input terminals on the
auxiliary power amplifier, and connect the surround back
speakers to the power amplifier (see page 23 for details).
2. Set the “Hardware Config”
→ “b. Surr Back” setting to “2 ch
(PRE OUT)” (see page 32).
Note:
If you connect the surround back speakers to the power amplifier
connected to the SURR BACK PRE OUT terminals on the DTR-6.4
for 7.1ch sound playback, do not connect the surround back
speakers to the SURROUND BACK SPEAKER terminals on the
DTR-6.4 Connecting the surround back speakers to both the DTR-
6.4 and power amplifier will not produce correct surround sound
effect.
Required for enjoying Dolby Digital EX, THX Surround EX (DTR-
6.4 only), or DTS-ES audio.
Improves the quality of sound effects and the realistic acoustics.
Only one surround back speaker
Connect the speaker to the SURROUND BACK SPEAKER
terminals on the DTR-6.4/5.4.
Two surround back speakers (DTR-6.4 only)
When using two surround back speakers, make connections
between the PRE OUT terminals on the DTR-6.4/5.4 and the audio
input terminals on the external stereo amplifier, and connect the
speakers to the external amplifier.
The figure on left below shows the speaker placement for dipolar
speakers.
Dipole speakers are the bidirectional speakers which produces same
sound in two directions such as both forward and backward.
Most dipole speakers have an arrow on them which can be used to
match the audio phase*. For making the audio phase in the room
correct, dipolar surround speakers should be placed so that their
arrows point toward the screen and dipolar surround back speakers
should be placed so that their arrows point each other.
*phase: The word represents the specific waveform point in a sign wave
cycle (0 to 360 degrees). When the distance between speakers, the speaker
