  • Page 5: Congratulations

    Before setting up your new MOON 850P, we encourage you to please read this manual thoroughly to properly acquaint yourself with its features. We hope you enjoy listening to the MOON 850P dual-mono preamplifier as much as the pride we have taken in creating this fine audio product.
  • Page 6: Introduction

    Installation & Placement The MOON 850P dual-mono preamplifier is very heavy and should be placed on a solid, level surface. You should avoid placing it near a heat source or inside a closed cabinet that is not well ventilated as this could compromise the preamplifier’s performance and reliability.
  • Page 7: Connecting The 850P Preamplifier & Controller

    850P preamplifier directly into a dedicated AC outlet and avoid using an extension cord. The MOON 850P is equipped with our M-Octave Damping system, whereby the main audio circuit board is coupled to the chassis using an 8-point floating suspension that is designed to eliminate distortion caused by the “Microphonic effect” of airborne vibrations.
  • Page 8: Front Panel Controls

    MOON 850P Dual-Mono Preamplifier Front Panel Controls Figure 2: Front panel of MOON 850P dual-mono Controller The front panel will look similar to Figure 2 (above). The large display window normally indicates the current volume level and, whenever you change the input, it will briefly show the selected input. On the left side of the display window, are six (6) buttons.
  • Page 9: Software Setup

    The MOON 850P preamplifier provides a range of five-hundred and thirty (530) unique volume settings. This is achieved as follows: Within the 0.0dB to 30.0dB range, you can increase and decrease the volume in 1.0dB steps. From the 30.0dB to 80.0dB range, you can increase and decrease the volume by either 0.1dB or 1.0dB steps;...
  • Page 10 “AUX1” will appear in the display. By rotating the volume control clockwise, you will scroll through more than 25 generic choices appearing in alphabetical order (AUX1 … CD … TUNER, etc.), various MOON source model names (i.e. ANDROMEDA … ORBITER, etc) and finally a choice called “CUSTOM” which allows you to create your own text label of up to 8 characters in length (refer to the example at the end of this section for more details).
  • Page 11 (continued) The MOON 850P is equipped with two 12 Volt trigger outputs. When an input is assigned to a 12 Volt trigger, the device connected to the trigger will automatically start-up whenever you switch to that input. The default setting for all seven inputs is on.
  • Page 12: Rear Panel Connections

    Figure 3: Rear panel of MOON 850P Preamplifier The rear panel of the MOON 850P dual-mono preamplifier will look similar to Figure 3 (above). There are two rows of connectors; the top row contains single-ended RCA inputs/outputs and the bottom row contains balanced XLR inputs/outputs, as well as the three input connections from the separate digital controller chassis.
  • Page 13: Simlink

    A third feature of SimLink™ involves the “Standby” function. By pressing down and holding the “Standby” button for 2 seconds on the 850P, all other MOON components connected via the SimLink will go into “Standby” mode along with the 850P. The same logic applies when switching from “Standby” to active mode.
  • Page 14: Remote Control Operation

    The MOON 850P Dual-Mono preamplifier uses the ‘FRM-3’ full function, all aluminum backlit remote control (figure 5). It operates on the Philips RC-5 communication protocol and is can be used with other MOON components such as CD Players, DAC’s, Integrated Amplifiers, as well as other Preamplifiers.
  • Page 15: Balanced Operation

    For example, when one conductor is carrying a signal of +10 Volts, the other will be carrying a signal of –10 Volts. When these two inverted signals on a balanced line are output from the MOON 850P, any noise picked up by the interconnect will be eliminated since a differential circuit amplifies only the difference between these two signals: Noise on a balanced interconnect will be equal on both conductors and therefore not be processed.
