Adjustment Procedure; When Using Only The Subwoofer (Sl-105) - Onkyo HTP-2 Instruction Manual

Adjustment procedure

I Adjusting the cut-off frequency and volume
POWERED SUBWOOFER
FREQUENCY
50 200
Hz Hz
Recommended level for the HTP-2 package system
Use the cut-off frequency (FREQUENCY) and volume
(OUTPUT LEVEL) knobs on the front of the subwoofer (SL-
105) and adjust the levels to the desired level in
accordance with the layout of your room and the positioning
of all your components. If the playback frequency range
and volume of the subwoofer are not set to proper levels,
distortions in the playback characteristics can result.

terminals
1. Using speaker cables and the speaker cables that came
with your speakers, connect the SL-105 speaker-level
input (INPUT FROM AMP/ RECEIVER) terminals and
the amplifier's speaker terminals.
2. Connect the Right and Left speakers to the SL-105
speaker-level output (OUTPUT TO SPEAKERS)
terminals.

Although it is recommended to set the cut-off frequency and
output level settings as high as possible, it is difficult to
notice the extremely low frequency bass sounds. This
makes it possible to accidentally set the volume level too
high. In order to prevent this, back the levels down just a bit
to ensure the proper balance.
Note:
Make sure that the input levels do not reach excessive
levels. The HTP-2 is designed for playing back music at a
normal volume, but if the input levels are set to enormous
levels, it may damage the speakers. Also, always first lower
the volume at the amplifier before changing the settings of
any switches to prevent accidental damage.

For details on how to connect the speaker cables, see the
previous page.
Notes:
• When connecting the speaker cables, be sure not to
mistake the (+) and (-) and the L (left) and R (left). If the
speaker cables are connecting incorrectly, there will be
a loss of fidelity in the bass sound ranges.
• The speakers connected to the SL-105 speaker-level
output (OUTPUT TO SPEAKERS) terminals must have
an impedance equal to or greater than the rating
indicated on the amplifier connected to the speaker-
level input (INPUT FROM AMP/ RECEIVER) terminals.
Otherwise, amplifier damage may occur.
• Do not use BTL (Balanced Transformer-Less) type
amplifiers. Using a BTL amplifier may cause damage to
both the amplifier and the subwoofer. Ordinary
amplifiers are not BTL amplifiers. For details, see the
amplifier's instruction manual.
