■ Connection to amplifier’s (receiver’s) speaker
terminals
1. Using speaker cables and the speaker cables that came
with your speakers, connect the SL-105’s SPEAKER
LEVEL INPUT terminals and the amplifier’s speaker
terminals.
2. Connect the Right and Left speakers to the SL-105’s
SPEAKER LEVEL OUTPUT terminals.
When using only the subwoofer (SL-105)
■ Connection with a preamplifier
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 terminals must have an impedance equal to or
greater than the rating indicated on the amplifier connected
to the SPEAKER LEVEL INPUT 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.
Note:
With an ordinary preamplifier having two output channels,
connect both the Right and Left jacks.

Adjustment procedure
■ Adjusting the cut-off frequency and volume
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.

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-L50 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.
