Setting bass sound

7 Setting subwoofer output—SUBWOOFER OUT

The subwoofer emits the LFE signals* and the bass elements
of each speaker set “SML (small).”
You can also make the bass elements of the front speakers
(MAIN) emitted through the subwoofer.

SW LFE

The subwoofer emits the LFE signals and
the bass elements of the speakers set to
“SML (small).”

SW LFE+MAIN

The subwoofer emits the LFE signals and
the bass elements of the speakers set to
“SML (small).” The subwoofer also emits
the bass elements of front speakers (MAIN)
when no LFE signal nor the bass elements
of “SML (small)” speakers exist.

Initial setting:

LFE

* The LFE signals are emitted only when playing the following

software with the LFE signals:

– Dolby Digital multi-channel software
– DTS multi-channel software

When playing analog source or linear PCM software, no LFE

signal is emitted.

NOTE

When “SUBWOOFER” is set to “NO” (see page 30), you cannot select
“SUBWOOFER OUT.”

7 Setting the crossover frequency—CROSSOVER

Small speakers cannot reproduce the bass sounds efficiently.
If you use a small speaker in any position, this receiver
automatically reallocates the bass sound elements assigned to
the small speaker to the large speakers.
To use this function properly, set this crossover frequency
level according to the size of the small speaker connected.
• If you have selected “LRG (large)” for all speakers (see page

30), this function will not take effect (“CROSS OFF” appears).

• If you have performed Precise Surround Setup on pages 16

to 18, this setting is not required.

Adjustable range: 80 Hz to 200 Hz (in 10 Hz intervals)
