SimLink™
The SimLink™ provides communication features
between various MOON components. For example,
if you were to connect the 650D to the 740P
Preamplifier via the SimLink™, pressing the X (play)
button on the 650D would cause the preamplifier
automatically switch to it’s designated input for the
CD Player. You must assign the input with the
name “650D” for this feature to work . If you
were to adjust the brightness level of the large
digital display window using the “Display” button on
the 740P, the brightness level of the 650D’s
display will automatically adjust to the same
brightness level as that of the 740P. Since the
SimLink™ is a true bi-directional connection,
adjusting the 650D’s brightness level will
automatically adjust the brightness level of the
740P.
A third feature of SimLink™ involves the “Standby”
function. By pressing down and holding the
“Standby” button for 2 seconds on the 740P, all
other MOON components connected via the SimLink
will go into “Standby” mode along with the 740P.
The same logic applies when switching from
“Standby” to active mode.
The connection rules for the SimLink™ are very
basic. You must always connect the supplied cable
between one component’s “SimLink™ Out” jack and
another component’s “SimLink™ In” jack. If you
inadvertently connect the cable between either two
“SimLink™ In” or two “SimLink™ Out” jacks, the
SimLink™ communication feature will not function.
Also, there is no master component in a SimLink™
chain; no one particular component operates as the
main communications controller.
Operating the 740P
We recommend that you leave your MOON 740P
dual-mono preamplifier powered up at all times to
maintain optimal performance. When you plan to be
away from your home for a few days, powering off
the preamplifier may not be a bad idea. Once fully
“broken-in”, please keep in mind that your 740P will
require several hours of playing time before it
reaches its peak performance after you’ve powered
it up again.
Turning on your MOON 740P for the first time
Prior to turning the preamplifier on for the first time,
make sure that every cable is properly connected to
avoid any problems. Flick the main rocker switch,
located on the rear panel, labeled “POWER” to the
‘1’ (on) position to place your 740P in to standby
mode. Next, briefly press the push button labeled
“Standby” located on the front panel. You will hear a
very faint click sound confirming that everything is in
order. The blue LED on the front panel will
illuminate, indicating that the 740P is now powered
up and ready for use.
On and Off Sequence
To avoid having any annoying noises (ie. “thumps”
and “pops”) emanate from your speakers when
powering your 740P on or off, you should always
power up your 740P preamplifier before powering
up your amplifier. As well, always power down your
740P after powering down your amplifier.
