These terminals output signals sent from the amplifier to
the main speakers directly.

2

INPUT1 (FROM AMPLIFIER) terminals

Used to connect this unit with the speaker terminals of the
amplifier.

3

INPUT2 terminals

Used to input line level signals from the amplifier.

4

VOLUME control

Adjusts the volume level.  

5

HIGH CUT (HIGH/LOW) switch

Selects the high frequency cut off point.
Normally, set to LOW, however, you may set to HIGH if
necessary. Refer to “Note about setting the HIGH CUT
switch” on page 13. 

6

AUTO STANDBY (HIGH/LOW/OFF) switch

By setting this switch to the HIGH or LOW position, this
unit’s automatic power-switching function operates as
described right. If you do not need this function, set to the
OFF position.
* Make sure to change the setting of this switch only when

this unit is in the standby mode.

7

Power indicator

Lights in green when the POWER switch set to the ON
position, and goes off when set to the OFF position.

* Standby mode

If the POWER switch is set to the ON position and the
AUTO STANDBY switch is set to the HIGH or LOW
position, this indicator lights in red when no signal is
input to this unit.

8

POWER switch

Set this switch to the ON position to turn on the power of
this unit. When the power of this unit is on, the power
indicator above the POWER switch lights in green.  Set
this switch to the OFF position to turn off the power of this
unit.

Automatic power-switching function
When you play a source, the power of this unit turns on
automatically by sensing audio signals input to this unit.
This unit turns into the standby mode automatically if the
source being played is stopped or the input signal is cut off
for several minutes.
This function will operate by sensing a certain level of low
frequency input signal. Its sensitivity is high in the HIGH
position and low in the LOW position of the AUTO
STANDBY 
switch. Set this switch to whichever position
you like. In the HIGH position, the power will turn on even
with a low level of input signal, but on the other hand this
unit may not turn into the standby mode when there is an
input signal even if its level is extremely low.
* There may be a case that the power turns on

unexpectedly by sensing noise from other appliances. If
it occurs, set the AUTO STANDBY switch to the OFF or
LOW position.

* The level of low frequency input signal differs with each

source, and each different part on the same source. So,
this function may not operate properly depending on
some sources.

This function is available only when the power of this
unit is on (by setting the POWER switch (

8

) to “ON”).
