Remote Only Functions
In addition to the controls found on the
front panel, the remote control offers
access to the following additional
features of the LS28SE.
Hours
Pressing the ‘HOURS’ button will display
the total accumulated hours of operation
for the LS28SE. This is useful to determine
the approximate number of hours the
vacuum tubes have been in use. After
five seconds, the display will revert to the
normal operation screen. After replacing
vacuum tubes, the hours counter should
be reset (see instructions under ‘Settings
Menu’ on page 16).
Note
The installed 6H30 vacuum tubes have an
average life span of approximately 4,000
hours. After this time, we recommend
replacing them to maintain the best
performance of your preamplifier.
Input Select Buttons
The input buttons labeled BAL 1-4 and
SE 1-4 allow direct selection of each of the
eight inputs available on the LS28SE.
Display Brightness Adjustment
The front panel display has six brightness
settings, as well as the ability to dim
the display completely. To change the
brightness, use the ‘DSP UP’ or ‘DSP DN’
buttons on the remote. Note that when
the display is completely dimmed, a
small square appears in the middle of the
display to indicate the unit is powered on.
Balance
The Balance control adjusts the output
from center position to the left or right
channels, which in turn will shift the center
point of the sonic image. This is useful in
the event the main listening position is not
centered between the speakers, or can
help with certain room anomalies.
To adjust the balance, press the ‘BAL
L’ or ‘BAL R’ button on the remote. The
balance scale will appear in the middle of
the display, and the indicator will move in
the selected direction:
After five seconds of inactivity, the
balance scale will disappear from the
screen. If the balance has been shifted to
the right or left, ‘R+’ or ‘L+’ will appear at
the bottom left corner.
