Connecting Speakers
—Continued
To get more powerful sound output, you can make the
BTL (Bridged Transless) connection using the front and
surround back speaker terminals on the DTR-10.5. In
this connection, two speaker outputs of the stereo
amplifier will be used as mono output by combining the
individual stereo channel outputs, allowing you to get
about twice the output.
Note:
When using the BTL connection, make sure that the
speaker impedance is 8 ohm or higher.
For the settings on the BTL connection, see page 88.
In the BTL connection, the (–) L/R speaker terminals on
the DTR-10.5 will not be used.
1. Connect the (+) terminal on the right speaker to the
FRONT R SPEAKERS (+) terminal on the
DTR-10.5 and the (–) terminal on the right speaker
to the SURR BACK R SPEAKERS (+) terminal on
the DTR-10.5.
2. Connect the (+) terminal on the left speaker to the
FRONT L SPEAKERS (+) terminal on the
DTR-10.5 and the (–) terminal on the left speaker
to the SURR BACK L SPEAKERS (+) terminal on
the DTR-10.5.
When you use bi-wiring-enabled speakers for the front
speakers, you can make the bi-amp connection. In this
connection, the front and surround back speaker
terminals will be used for tweeter and woofer,
respectively. This connection allows you to obtain high
quality sound as well as maximum treble and bass
performance from the tweeter and woofer, enriching
your sound experience.
Caution:
• When making the bi-amp connection, make sure
to remove the shorting bars connecting the high
range (Tweeter) and low range (Woofer)
terminals.
• When using the bi-amp connection, make sure that
the speaker impedance is 8 ohm or higher.
For the settings on the bi-amp connection, see pages 88,
89.
1. Connect the (+) tweeter terminal of the right
speaker to the FRONT R SPEAKERS (+) terminal
on the DTR-10.5 and the (+) woofer terminal of
the right speaker to the SURR BACK R
SPEAKERS (+) terminal on the DTR-10.5.
2. Connect the (–) tweeter terminal of the right
speaker to the FRONT R SPEAKERS (–) terminal
on the DTR-10.5 and the (–) woofer terminal of
the right speaker to the SURR BACK R
SPEAKERS (–) terminal on the DTR-10.5.
3. Connect the (+) tweeter terminal of the left speaker
to the FRONT L SPEAKERS (+) terminal on the
DTR-10.5 and the (+) woofer terminal of the left
speaker to the SURR BACK L SPEAKERS (+)
terminal on the DTR-10.5.
4. Connect the (–) tweeter terminal of the left speaker
to the FRONT L SPEAKERS (–) terminal on the
DTR-10.5 and the (–) woofer terminal of the left
speaker to the SURR BACK L SPEAKERS (–)
terminal on the DTR-10.5.
