PANEL VIEW
Front panel
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.
