The possibilities are endless ...
The MOON 340i allows you to integrate your
music system in distinctively new ways.

The MOON 340i redefines the possibilites of what an integrated amplifier can be. Loaded with numerous convenient features and unbeatable sonic performance, the 340i provides for unprecedented flexibility. Featuring an options package, unheralded in the world of high-performance audio, which includes (1) an internal digital-to-analog converter (USB-2, S/PDIF & TosLink digital inputs), (2) an internal RIAA phono preamplifier (MM & MC) and (3) a balanced line-level input. All 3 of these options are available in any combination, either at the time of purchase or as a future upgrade.

The MOON 340i combines over 30 years of experience in the design and manufacturing of award winning products with numerous unique technologies found in many of our other components. The MOON 340i, rated at 50 watts/channel into 8Ω (100 watts/channel into 4Ω) will be the heart and soul of your home-entertainent system for many many years ... call it the the birth of a legend.


Since October 2012, the optional Digital-to-Analog Converter's fully asynchronous USB input is capable of 24-bit/192kHz performance. An upgrade is available for units (340i and i3.3) manufactured prior to this date.

340i Technical Features

· A massive oversized power supply using a custom toroidal transformer design
· 5 line-level inputs including a front-mounted 1/8" mini-jack for personal media players
· Headphone output on 1/4" TRS jack located on the front panel
· One audio input which functions as a "pass-through", bypassing the gain stage to accommodate
  a component such as a home-theater processor, whose own volume control is used instead.
· Proprietary MOON Bipolar output transistors with unprecedented gain linearity resulting
  in improved bass response and even more accurate sonic reproduction
· "Class A" output to 5 watts for greater efficiency
· 12 Volt trigger output for remote operations
· RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates
· IR input for external control
· SimLink™ controller port for 2-way communications with other compatible MOON components
· Rigid chassis construction to minimize the effects of external vibrations
· Optimized selection of very high quality electronic components
· Low operating temperature for an ultra-long life expectancy
· Includes CRM-2 remote control.
