Processor Mode
The LS28 has the ability to assign unity gain
(also called ‘pass through’) to one of the
eight inputs available in the event it will be
integrated into a system with a secondary
control device, such as a surround sound
processor. When an input is assigned as
the processor input, the volume control on
the LS28 is disabled so that the processor’s
volume is the only control used.
To set up a processor input, connect the
left and right output channels from your
surround sound processor to the left and
right inputs of your choice on the LS28.
Press the ‘MENU’ button until ‘PROCESSOR
MODE’ is displayed, and press ‘ENTER’.
With ‘PROCESSOR’ displayed, turn the
volume knob, or use the up/down
volume buttons on the remote, to
select the desired input for processor
mode. Press the ‘ENTER’ button to
select the input, and ‘ENTER’ once
again to confirm the selection. The
LS28 will display ‘OKAY’ and show the
selected input on the bottom line.
When using the input selected for processor
mode, note that in place of the volume
number on the operation screen, a
‘pass through’ symbol will be shown.
Warning
When processor mode is assigned to an
input, do NOT connect a source (such as
a CD player or phono stage) to that input.
This will send full output from the source
to your amplifier(s), and could cause
serious damage to your loudspeakers or
amplifier(s) - not to mention your ears!
Operation
Tube Hours
The tube hours display shows the
accumulated time the LS28 has been
powered on. This is useful for determining
the number of usage hours of the installed
vacuum tubes. See A Note about Vacuum
Tubes on page 7 for specific information
regarding the tubes in the LS28.
To reset the tube hours counter, press
the ‘MENU’ button until ‘TUBE HOURS’
is shown. Press the ‘ENTER’ button to
display ‘ENTER TO RESET’. Press ‘ENTER’
again and the display will read ‘ENTER TO
CONFIRM’. A final press of the ‘ENTER’
button will reset the tube hour counter
to 0 and the display will show ‘OKAY’.
Note
Once the hour counter has been
reset, the total accumulated
hours cannot be recalled.
