MOON Andromeda CD Player
Balanced Operation
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 both the
preamplifier and amplifier, then 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 output from the MOON Andromeda, 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.
Remote Control Operation
The MOON Andromeda CD Player uses the ‘FRM-2’ full function, all aluminum remote
control (figure 3). It operates on the Philips RC-5 communication protocol and is can be
used with other Simaudio MOON components such as the P-5 and P-3 Preamplifiers, AIR
FM Tuner and both the i-5 and i-3 integrated amplifiers.
The ‘FRM-2’ remote uses three AAA batteries (included). To install them, use the
supplied Allen key to remove the three screws located on the back plate; insert the
batteries in the correct direction and then screw the back plate back into place.
To operate the Andromeda with this remote control, you must first press the button
labeled ‘CD’ on the top left corner.
The lower section of the ‘FRM-2’ has nine (9) buttons, eight (8) of which operate the
Andromeda. All of these functions are available on either the top panel or front panel of
the CD Player. Please refer to these aforementioned sections for a more detailed
description of each of these buttons:
X Play the compact disc loaded into the player
Skip to the previous track on the disc
Skip to the next track on the disc
Scan backwards through the current track of the disc
Pauses the player
Scan forward through the current track of the disc
2 Repeat the entire disc (1x) or the current track (2x)
Stop playing the current track
