SAFETY-RELATED COMPONENT
WARNING!!

COMPONENTS IDENTIFIED BY MARK ON THE
SCHEMATIC DIAGRAM AND IN THE PARTS LIST ARE
CRITICAL FOR RISK OF FIRE AND ELECTRIC SHOCK.
REPLACE THESE COMPONENTS WITH ONKYO
PARTS WHOSE PART NUMBERS APPEAR AS SHOWN
IN THIS MANUAL.
MAKE LEAKAGE-CURRENT OR RESISTANCE
MEASUREMENTS TO DETERMINE THAT EXPOSED
PARTS ARE ACCEPTABLY INSULATED FROM THE
SUPPLY CIRCUIT BEFORE RETURNING THE
APPLIANCE TO THE CUSTOMER.

SERVICE NOTE

1. Replacing the fuses

This symbol located near the fuses indicates that the fuse used is
fast operating type. For continued protection against fire hazard, re­place with same type fuse. For fuse rating refer to the marking adja­cent to the symbol.

1 Power switch (POWER) and indicator

Pressing this button turns the power on (the indicator
lights). Pressing the button again turns the power off
(the indicator goes out).
Red: Unit is in standby mode
Green: Unit is in operation

2 Frequency adjusting knob (FREQUENCY)

Use this knob to select the high-frequency range at
which you wish to cut off the signal to the subwoofer.
You can select any frequency between 50 Hz and 200
Hz depending on the characteristics of the speaker
system being used with the SL-105.

3 Output level adjusting knob (OUTPUT LEVEL)

Use this knob to adjust the output level of the
subwoofer.

A Low-level input jacks (LINE INPUT)

Connect these jacks to the LINE OUT jacks of the
amplifier etc.

B Auto standby switch (AUTO STANDBY)

This switch is used to turn on and off the auto standby
function.
ON: This activates the auto standby function.
If a constant level signal is not received from the
amplifier (or receiver) over a period of a few minutes,
the SL-105 automatically enters the standby state. If a
constant level signal is later received from the amplifier
(or receiver), the power is automatically turned back on.

OFF: Deactivates the auto standby function.
Notes:

The auto standby function operates on the existence

*

or absence of a constant level input signal. If the auto
standby function does not operate properly, try
slightly increasing (or decreasing) the output level of
the amplifier or receiver. (Note that output levels of
some amplifiers and receivers cannot be adjusted.
For more details regarding your components, refer to
the instruction manual supplied with them.)

If noise from peripheral components causes the

*

incorrect operation of the auto standby function, or if
outputting low volumes (i.e., during the nighttime)
causes the auto standby function to activate, turn off
the auto standby function.

The auto standby function only operates while the

*

power switch for the SL-105 is turned on.

C Speaker-level input terminals

(INPUT FROM AMP/RECEIVER)

Connect these input terminals to the speaker output
terminals of your amplifier or receiver.

D Speaker-level output terminals

(OUTPUT TO SPEAKERS)

The speaker-level signal to the front speakers is output
from these terminals.
