MOON 110LP Phono Preamplifier
Operating the 110LP
We recommend that you leave your MOON 110LP Phono Preamplifier powered up at all times to maintain optimal
performance. In the event that you plan to be away from your home for a few days, powering off the Phono Preamplifier may
not be a bad idea. Once fully “broken-in”, please keep in mind that your 110LP will require several hours of playing time
before it reaches its peak performance after you’ve powered it up again.
IMPORTANT: A turntable with a functional
cartridge MUST be connected to the MOON 110LP prior to connecting the AC power cord, otherwise you may damage your
amplifier and/or loudspeakers.
Making the AC Connection
For the best sonic performance, it is preferable that you plug your MOON 110LP power supply directly into a dedicated AC
outlet and avoid using an extension cord. Then connect the terminated end of the power supply cord to the input labeled
12VDC, located on the rear panel of the phono preamplifier’s chassis. In order to obtain the maximum performance from your
audio system, we strongly recommend that the power supply cord not come into physical contact with any of the interconnect
cables running to and from your 110LP. In the event that this can’t be avoided, you should ensure that any cables coming
into contact with each other are crossed at ninety degree angle to minimize the contact area.
Powering up your MOON 110LP for the first time
Since this Phono Preamplifier is not equipped with an on/off power switch, when connecting/disconnecting the AC power
cord you are actually turning the unit on/off. Prior to making the AC connection for the first time, make sure that every
cable is properly connected to avoid any problems. Once the 110LP is connected to an AC source, The blue LED on the
unit’s front panel will illuminate.
On and Off Sequence
To avoid having any annoying noises (ie. “thumps” and “pops”) emanate from your speakers when powering your 110LP on
or off, you should i) Always power up your 110LP before powering up your preamplifier and/or integrated amplifier and ii)
always power down your 110LP after powering down your preamplifier and/or integrated amplifier.
