MOON i-5080 Integrated Amplifier
Front Panel Controls (continued)
The “Input” selector button allows you to choose which input source you wish to listen to. The MOON
i-5080 integrated amplifier has six (6) inputs. The A4 input is a ‘pass-through’ which bypasses the
i-5080’s gain section, allowing you to control the gain setting via the source component’s own volume
control – a home theater processor for example. Adjusting the volume on the i-5080 will have no
effect whatsoever when the A4 input is selected. You may reconfigure the A4 input to function like the
five (5) other inputs as follows: Simply press and hold down the “Mute” button for approximately 5
seconds; you don’t have to be on the A4 setting to do this. You can convert this input back to ‘pass-
through’ mode by repeating the procedure. As well, powering down the i-5080 via the rear panel
rocker switch will reset the the A4 to the factory default of ‘pass-through’ 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’.
