MOON 300 D v.2 Digital-to-Analog Converter
Operating the MOON 300 D
We recommend that you leave your MOON 300 D DAC 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, switching the 300
D into “Standby” mode may not be a bad
idea. Once fully “broken-in”, please keep in mind that your 300
D will require several hours of playing time before it reaches
its peak performance after you’ve powered it up again.
Making the AC Connection
Connect the supplied AC power cable to the IEC receptacle, located on the rear panel of the DAC’s chassis. Ensure that the
AC wall outlet you use has a functioning ground. For the best sonic performance, it is preferable that you plug your MOON
300
D directly into a dedicated AC outlet and avoid using an extension cord.
In order to obtain the maximum performance from your audio system, we strongly recommend that the detachable power
cord not come into physical contact with any of the interconnect cables running to and from your 300
D. 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 300 D for the first time
Since this Digital-to-Analog Converter 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 300 D is connected to an AC source it will be in “Standby
mode”. When you press the “Standby” button on the front panel, the 300
D will be ready for use and the blue LED will
illuminate.
On and Off Sequence
To avoid having any annoying noises (ie. “thumps” and “pops”) emanate from your speakers when powering your 300 D on
or off, you should
1) Always power up your 300 D before powering up your preamplifier and/or integrated amplifier.
2) Always power down your 300
D after powering down your preamplifier and/or integrated amplifier.
Optional remote control operation
Your MOON 300 D is equipped with an infrared input (as mentioned in the previous section) that allows for the remote
operation of certain functions. Using an aftermarket infrared remote control receiver in conjunction with the MOON CRM-2
remote control, you will be able to (i) toggle between standby mode and operational mode and (ii) switch between the four
(4) digital inputs. Please contact your authorized MOON retailer for further information.
