AUTO – ON / mains switch
Switches
,
and
determine the sub-woofer’s
behaviour when switched on and off:
MAINS SWITCH / MAINS SOCKET:
The mains switch acts as a mains isolation switch, i. e. it
switches the sub-woofer off permanently. If you will not
be using the speaker for a long period, the mains switch
should always be switched off, or the mains lead
disconnected.
AUTO / ON:
This switch either activates the sub-woofer’s automatic
power-on circuit (‘
AUTO’
setting) or switches it on
permanently (‘
ON
’ setting).
‘AUTO’ setting
•
The speaker switches on
automatically
as soon as:
-
a switching voltage is present at the switch input
of the
DIN IN
socket (in this case switch
must
be set to the ‘
CTRL
’ setting)
-
a music signal is present (in this case switch
must be at the ‘
’
setting)
•
The
LED
on the front panel glows
green
.
•
If the switching voltage at the
DIN IN
socket declines,
or about 60 minutes after the music signal ceases,
the sub-woofer automatically switches to stand-by
mode; - the
LED
on the front panel glows
red
.
'ON' setting
If the switch is set to the ‘
ON
’ position, the sub-woofer
remains switched on permanently, regardless of the
input signal.
Note:
The ‘
ON
’ setting is suitable for use with a switched mains
power supply socket.
CTRL
This switch defines the signal to which the sub-woofer’s
automatic power-on circuit responds.
In the
‘CTRL’
setting the sub-woofer receives the power-
on signal via the 8-pin DIN socket
‘DIN IN (SC
LINK
)’
; in
the ‘
’ setting the presence of a music signal at the
input sockets ‘
HI LEVEL IN’
or
‘CINCH IN’
triggers the
automatic power-on circuit.
Note:
This switch only has any effect if the automatic power-on
circuit is activated, i. e. switch
must be set to the
‘AUTO’
position.
HI LEVEL OUT
If the sub-woofer is connected to a power amplifier (see
HI LEVEL IN
), satellite loudspeakers can be connected
to these speaker outputs.
