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. In ‘pass-through’ mode, adjusting the volume on the i 3.3 will have no effect whatsoever when the “A2” input is selected. To put the “A2” input into ‘pass-through’ mode, press and hold down the “Mute” button for approximately 2 seconds while on the “A2” input. The front panel display will change from “A2” to “HT”. To reconfigure the “A2” input to function like the other inputs, repeat the aforementioned procedure. As well, powering down the i 3.3 via the rear panel rocker switch will automatically reset the the “A2” to the factory default ‘normal’ mode.

The rotary “Volume” control determines the output level. Turning it clockwise increases the volume level and turning it counterclockwise decreases the volume level.

The “Phones” jack is used for connecting a pair of stereo headphones to the MOON i 3.3. The input connector is a standard ¼” stereo TRS jack. When a pair of headphones are used with the i 3.3, the loudspeakers will still receive an output signal. However, you should use the aforementioned “Spk off” button for private listening.

Optional Digital Inputs

The Digital Input option includes four (4) separate inputs: “D1” uses an optical Toslink connector, “D2” and “D3” use S/PDIF on an female RCA connector and “D4” uses a type-B USB connector. The “D1” is intended for use with a source equipped with a TosLink digital output such as a satellite dish receiver; The “D2” and “D3” inputs are intended for use with a source equipped with a S/PDIF digital output such as a DVD player, music server or disc transport. The “D4” input is for use with a computer equipped with a USB connector and music player software such as iTunes or Winamp; you cannot connect a USB flash drive to the “D4” input.

When you select one of the digital inputs as described in the aforementioned section, the display window will show which of the four digital inputs is selected. At the same time, the right side of the display window will initially show four dashes as follows “----” which indicate that the i 3.3 is in the process of locking onto the external digital signal – this may take several

seconds. When the i 3.3 successfully locks onto the digital signal, the four dashes will be replaced by the sampling rate of this digital signal. When the signal cannot be locked onto, “----” remains in the display window. The optional digital-to-analog

circuit option inside the MOON i 3.3 is capable of processing the following seven (7) different sampling rates: 32.0kHz, 44.1kHz, 48.0 kHz, 88.2kHz, 96 kHz, 176.4kHz and 192kHz.
