Front Panel Controls
Figure 1: Front panel of MOON 740P dual-mono 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, “Е 00 Ж” 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.
