    MOON i 3.3 Integrated Amplifier Front Panel Controls Figure 1: MOON i 3.3 Front panel The front panel will look similar to Figure 1 (above). The large display window indicates the selected input source. In the event that your i 3.3 includes the digital input option, additional information will appear in the display window. Refer to the section entitled “Optional Digital Inputs”...
  • Page 8: Optional Digital Inputs

    MOON i 3.3 Integrated Amplifier Front Panel Controls (Cont’d) The “A2” input can be configured as a ‘pass-through’ which bypasses the i 3.3’s gain control section, allowing you to control the gain setting via the connected source component’s own volume control – a home theater processor for example; In other words, this input operates like the input of a power amplifier.

    MOON i 3.3 Integrated Amplifier Optional Phono Section (Cont’d) Internal Settings There are three (3) types of settings available on the optional phono section of the MOON i 3.3 Preamplifier; Capacitance loading, Resistance loading, and Gain level. Each setting is adjustable through the use of jumpers. For each type of setting, there are 2 banks of jumpers –...
  • Page 11: Optional Balanced Input

    MOON i 3.3 Integrated Amplifier Optional Balanced Input The balanced input option provides for one additional line-level input on an XLR connector. The “B1” input uses a fully balanced differential circuit and is intended for use with a source component that outputs a fully balanced differential signal. The MOON i 3.3 optional balanced input takes full advantage of the benefits of balanced circuitry: When using an unbalanced interconnect, the audio signal runs through both the center wire and the shield/ground wire.
  • Page 12 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;...
  • Page 13: Simlink

    MOON i 3.3 Integrated Amplifier SimLink™ The SimLink™ provides communication features between various MOON components. For example, if you were to connect the CD 3.3 to the i 3.3 via the SimLink™, pressing the (play) button on the CD 3.3 will cause the i 3.3 to automatically switch to the input labeled ‘CD’.
  • Page 14: Remote Control Operation
