MOON i 3.3 Integrated Amplifier
Rear Panel Connections (cont’d)
In the event that your MOON i 3.3 is equipped with the aforementioned the digital input option, you will find 4 digital inputs
labeled D1, D2, D3 and D4. The D1 input is on an optical Toslink connector; both the D2 and D3 inputs are on a S/PDIF
connector; the D4 input is on a USB type B connector.
Below the area reserved for the optional digital inputs are a series of input/output connectors for custom type installations:
From left to right there 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. Next, there’s a 1/8” mini-jack input for use with aftermarket infrared remote
control receivers. Then there’s a 12V trigger output on a 1/8” mini-jack that can power up a connected component (with a
12V trigger input) at the same time that the i 3.3 is powered up. Finally, there’s a full-function bi-directional RS-232 port
control and status for custom integration or automation on a DB9 connector.
The MOON i 3.3 is equipped with a pair of gold-plated binding posts. The right channel speaker output is located above the
analog inputs. The left channel speaker output is located to the right of the digital inputs. Connect your loudspeakers, with the
cables of your choice, to these binding posts, paying attention to respect the polarity (“+” , “-” ) of the output.
Finally on the far right side is the “AC Fuse” socket cover, the main power switch (“0”=off, “1”=on) and the IEC receptacle,
labeled “AC Power” for the included AC power cord.
You will notice that all RCA input and output connectors on the rear panel have been color coded: ‘white’ for the left channel
and ‘red’ for the right channel. A poor contact will degrade the signal substantially, and plugs and sockets should all look clean
and free of dirt and corrosion. The easiest way to clean them is to remove the cables from their sockets and push them back
in again. This procedure requires that your Integrated Amplifier and the rest of your components be completely turned off.
Not heeding this warning may result in serious damage to your equipment. Special contact cleaning fluids and enhancers
should not be used, as they deposit a difficult to remove residue which degrades the performance of your components.
