Using The Btl Connection; Using Bi-Amp Connection - Onkyo TX-NR1000 Instruction Manual

Connecting Speakers —Continued

Using the BTL Connection

To get more powerful sound output, you can make the
BTL (Bridged Transless) connection using the front and
surround back speaker terminals on the TX-NR1000/
TX-NR5000E. 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 pages 88,
89.

1. Connect the (+) terminal on the right speaker to the
FRONT R SPEAKERS (+) terminal on the
TX-NR1000/TX-NR5000E and the (–) terminal on
the right speaker to the SURR BACK R
SPEAKERS (+) terminal on the TX-NR1000/

2. Connect the (+) terminal on the left speaker to the
FRONT L SPEAKERS (+) terminal on the
TX-NR1000/TX-NR5000E and the (–) terminal on
the left speaker to the SURR BACK L SPEAKERS
(+) terminal on the TX-NR1000/TX-NR5000E.

Using Bi-amp Connection

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.
