Intended to meet the needs of the most demanding music connoisseurs, it is fully differential dual-mono design, rated at 125 watts/channel into 8 Ohms, offering authority, finesse and superb control. Using a variety of new technologies developed since the introduction of the Evolution Series, the 600i provides more sonic transparency and accuracy than ever before.

New technologies include (i) the M-eVOL2 volume control, with a phenomenal 530 steps, allowing for an extremely precise level adjustment just like the 850P Preamplifier; (ii) MOON output transistors, specifically designed for use in our amplifiers, provide tighter and more visceral bass performance, as well as unprecedented linearity thoughout the entire frequency spectrum; (iii) An input stage circuit which reduces noise, preserving image focus and integrity like never before. Although rated at "only" 125W per channel, the MOON 600i embodies both authority and finesse at all levels that suggests a much more powerful amplifier, just like all MOON products before it.

Of course, key features you'd expect in a MOON Evolution Series products are present such as our "no overall feedback" amplification circuitry, SimLink™ and M-Lock, just to name a few, as well as both RS-232 and IR ports for custom-install environments.

Features

• RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates
• IR input for external control
• Our "No overall feedback" design resulting in genuine real-time amplification, more accurate
• musical reproduction with respect to tonality, virtually non-existent IMD and the elimination
• of common phase errors resulting from feedback
• Custom proprietary toroidal transformer design with lower magnetic, electrical and thermal
• loss, yielding an improved power transfer and lower regulation factor. The result is increased
• current speed and better dynamics
• A dual-mono oversized power supply
• SimLink controller port for 2-way communications with other compatible MOON components
• M-eVOL2 volume control circuit using MDAC’s (operating in a current steering R-2R configuration)
• which alter the audiio signal’s amplitude yielding no sonic degradation of the signal, regardless
• of the selected volume setting
• Proprietary MOON Bipolar output transistors with unprecedented gain linearity resulting in
• improved bass response and even more accurate sonic reproduction
• M-Lock for “user selectable” maximum volume setting lock-out for each line input
• “Gain offset” for each individual line input with a ±10dB range
• Each line input is fully configurable to be “home-theater ready”, where the gain section of the
• 600i is bypassed
• 530 individual volume steps in 1dB and 0.1dB increments
• An exceptionally short signal path , yielding a much faster transient response
• 12 Volt trigger output for remote operation
• "Class A" output to 5 watts for greater efficiency
• 4-Layer PCB’s with pure copper tracings for a much shorter signal path; This results in
• greater sonic accuracy and a dramatically improved signal-to-noise ratio
• Ultra rigid chassis construction to minimize the effects of external vibrations
• Accurate matching of the very finest quality electronic components in a symmetrical circuit design
• Improved reliabilty through the elimination of moving parts
• Low operating temperature for a longer than normal life expectancy
• Includes FRM-2 remote control.
