MOON 350P Silver MOON 350P Black

Digital ... Analog ... or Both

The MOON MOON 350P is a high-performance differential preamplifier. Using circuitry derived from the Evolution Series, the 350P is a modular design that accepts optional plug-in modules: (i) a 24-bit/192kHz high-performance D/A converter with USB, optical (TosLink)and RCA (S/PDIF) inputs, and (ii) a configurable MC/MM Phono stage.

The MOON 350P's wide bandwidth and excellent dynamic range allows it to effortlessly reproduce high-resolution audio. A well organized and thorough rear panel allows for connectivity to virtually any audio component.

For the headphone enthusiast, the 350P is engineered with a discrete headphone amplifier stage, which allows it to effortlessly drive even the world's finest headphones. An audiophile-grade product with a toroidal tranformer-based large power supply, military-spec passive and active components, and state-of-the-art surface-mount manufacturing techniques help make the MOON 350P the finest affordable MOON preamplifier to date.

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 manufactured prior to this date.

350P Technical Features

· An oversized power supply using 2 toroidal transformers in conjunction with 3 stages of DC
  voltage regulation
· 7 line-level inputs (4 Single-ended & 2 balanced) including one front-mounted 1/8" mini-jack
  for personal media players
· Discrete headphone amplifier circuit with the 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.
· A full-function monitor loop
· Fixed (single-ended) and Variable (balanced & single-ended) line level outputs
· 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
· A symmetrical circuit design
· Rigid chassis construction to minimize the effects of external vibrations
· Optimized selection of very high quality electronic components
· Designed to be powered up at all times for optimal performance
· Includes CRM-2 remote control.
