Front Panel Controls
Figure 1: Front panel of MOON 740P Preamplifier
The front panel will look similar to Figure 1 (above). The large display window normally indicates the current
volume level and, whenever you change the input, it will briefly show the selected input label.
The “Standby” button disengages the input section
from the rest of the
740P ’s circuitry and turns off the
digital display. However, when in “Standby” mode all
audio circuitry remains powered up to help maintain
optimal performance. When switching back from
“Standby”, both the ‘input’ and volume settings are re-
established from the previous listening session. The
blue pilot LED will not be illuminated when the
740P is
in “Standby” mode.
The “Mute” button reduces your volume setting to zero.
Pressing the “Mute” button a second time will return the
output volume to its previous level. As well, adjusting
the volume level while the “Mute” function is engaged
will effectively defeat the muting function.
The “Display” button allows you to adjust the brightness
of the large digital display window. It also provides you
with the option of turning off the display. There are
three (3) different levels of brightness; The default is
medium. Pressing the “Display” button once will
increase the level to the highest setting. Pressing the
button a second time will decrease the brightness to
the lowest setting. Pressing the “Display” button a third
time returns the display to its default setting of
medium.
If you want to turn the display off, press and hold the
“Display” button for 2 seconds. When the display is
turned off, it will still come back on for a short period of
time whenever you press any of the buttons located on
the front panel or the remote control, using the
brightness level that was previously set; the display will
automatically turn off again once you are done. To turn
the display back on, simply press and hold the “Display”
button for 2 seconds.
The “
‡
Bal
ˆ
” buttons control channel balance;
Pressing the left arrow button causes a decrease in the
volume level of the right channel; pressing the right
arrow button causes a decrease in the volume level of
the left channel. The balance adjustment operates in
1% increments. When the balance is equal for both
channels, “
Å
00
Æ
” will appear in the front panel
display. The range for the balance control varies from
“
Å
100” for left channel only to “100
Æ
” for right
channel only.
The “
‡
Input
ˆ
” buttons allow you to choose which
input source you wish to listen to. The MOON 740P
dual-mono preamplifier has a total of five (5) inputs;
The first two (2) inputs are fully-balanced and use XLR
connectors labeled B1 and B2. The next three (3) inputs
are single-ended and use RCA connectors labeled S1, S2
and S3. Assuming that you’re currently listening to a
source component connected to input B1, the “
ˆ
”
allows to sequentially scroll forward through the
available inputs from B2, then S1, S2 and S3. The “
‡
”
button allows you to sequentially scroll backwards from
S3 to B1. Holding down either the “
ˆ
” or “
‡
“ button
will allow only a single change of the selected input.
You must press the button again to select the next or
previous input.
