3.3 Rear panel with optional balanced analog outputs
The rear panel will look similar to Figure 2 (above). On the left side is the analog audio output. There is one pair of RCA
analog audio output connectors labeled “ANALOG OUT” that you should connect to a stereo analog input on your preamplifier
or integrated amplifier.
In the event that you have purchased your MOON CD
3.3 with optional balanced analog circuitry, there will be a pair of XLR
balanced outputs located to the right of the RCA analog outputs. In this case, we strongly recommend that you use the
balanced XLR connectors on your CD
3.3 to maximize its level of performance:
When using an unbalanced interconnect, the audio signal runs through both the center wire and the shield/ground wire. Any noise
picked up by this interconnect (ie. nearby magnetic fields such as an AC power cord) will be reproduced by the amplifier and heard
through the loudspeakers. Conversely, a balanced interconnect has three separate conductors; one for the ground and two for the
actual signal. These two signals are identical except that one is 180 degrees out of phase with the other. For example, when one
conductor is carrying a signal of +4 Volts, the other will be carrying a signal of –4 Volts. When these two inverted signals on a
balanced line are input into a differential preamplifier, any noise picked up by the interconnect will be eliminated since a differential
circuit amplifies only the difference between these two signals: Noise on a balanced interconnect will be equal on both conductors
and therefore not be processed.
The MOON CD
3.3 is equipped with a S/PDIF digital input and a S/PDIF digital output, each on an RCA connector. The digital
output allows you to use your CD
3.3 as a stand-alone CD transport, whereby digital signal processing will be handled
externally by another digital-to-analog converter or surround processor. The digital input allows you to use your CD
3.3 as a
digital-to-analog converter in conjunction with a digital audio source component. Please refer to page 8 of the previous section
for complete details. You should always use a 75
Ω
digital audio cable terminated with RCA connectors whenever using the CD
3.3’s digital input and/or output to achieve optimal sonic performance.
Your MOON CD
3.3 is equipped with several features for custom type installations: To the right of the “Digital Output” is a
full-function bi-directional “RS-232” port control and status for custom integration or automation and uses a DB9 connector.
As well, there’s a 1/8” mini jack input for use with aftermarket infrared remote control receivers. The “IR in” connector is
located to the right of the “RS-232” port. Immediately to the right of the “IR” input are two (2) “SimLink” connectors labeled
“in” and “out” on 1/8” mini jacks. Please refer to the next section entitled SimLink for more details.
Finally on the right side is the “AC Power” section with a main power switch (“0”=off, “1”=on) and IEC receptacle for the
included AC power cord.
