MOON i-3 Integrated Amplifier

Front Panel Controls

Figure 1: MOON i-3 Front panel
The front panel will look similar to Figure 1 (above). The large digital display window indicates the relative gain setting (from
'0' to '50') for both the left and right channels. As well, whenever you change the selected input source, it's number will
appear in the window for 3 seconds before reverting back to the gain setting.
The "Stand by/On" button disengages the input section from the rest of the i-3's circuitry and turns off the digital display.
However, when in "Stand by" mode all audio circuitry remains powered up to help maintain optimal performance. When
switching back from "Standy by" to the "on" mode, both the 'input' and gain level settings will be memorized from the
previous listening session. The blue pilot LED will not be illuminated when the i-3 is in "Stand by" mode.
When the i-3 is operational, holding down the "Stand by/On" for two (2) seconds will turn off the front panel digital display.
Repeating this procedure will turn the front panel digital display back on. The sonic performance of the MOON i-3 may
improve slightly when the display is turned off.
The "Input" selector button allows you to choose which input source you wish to listen to. The MOON i-3 integrated amplifier
has six (6) inputs. The A4 input can be configured as a 'pass-through' which bypasses the i-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 'pass-through' mode, adjusting the volume on the i-3 will have no effect whatsoever when the A4 input is
selected. To put the A4 input into 'pass-through' mode, simply press and hold down the "Input" selector button for
approximately 5 seconds; you don't have to be on the A4 setting to do this. To reconfigure the A4 input to function like the
five (5) other inputs, repeat the aforementioned procedure. As well, powering down the i-3 via the rear panel rocker switch
will reset the the A4 to the factory default 'normal' mode.
Pressing the "Input" selector button allows you to sequentially cascade through each of the possible inputs in the following
order: CD, A1, A2, A3, A4 and A5. Holding down the "Input" will allow only a single change of the selected input. You must
press the button again to select the next input.
The "Vol Up" and "Vol Down" buttons control the gain setting, which ranges from '0' (no output) to '50' (full output). This
control doesn't function like a typical volume: When you press either of these volume control buttons, you're selecting a
specific gain setting on a shunt-to-ground based microprocessor circuit. This gain circuit, known as RGB-cs, doesn't degrade
the audio signal regardless of the setting, unlike all potentiometer based circuits.
The range of fifty (50) unique gain settings is based on neither a linear nor logarithmic scale. Instead, we decided on
relatively small variations for each of the lower position settings from '1' to '35'. The variations are somewhat larger from
positions '36' through '50'.
