810LP Reference Dual-Mono Phono Preamplifier Introduction Thank you for selecting the MOON 810LP Reference Dual-Mono Phono Preamplifier as a part of your music/cinema system. This component has been designed to offer state-of-the-art high-end performance in an elegant package, while retaining all the sonic hallmarks on which Simaudio has made its reputation. We have spared no effort to ensure that it is amongst the finest phono preamplifiers available.
810LP Reference Dual-Mono Phono Preamplifier Unpacking The MOON 810LP Phono Preamplifier should be removed from its box with care. The following accessories should be included inside the box with your phono preamplifier: 9 9 9 9 AC power cable One (1) pen shaped plastic hand tool for making DIP-switch adjustments This owner’s manual Warranty and product registration information (USA and Canada only) Once the 810LP is unpacked, inspect it thoroughly and report any damage to your dealer immediately.
10LP Reference Dual-Mono Phono Preamplifier Bottom Panel Layout Figure 1: MOON 810LP Bottom Panel layout Settings for cartridge resisitance loading, cartridge capaciitance loading, gain and equalization curve are all done using white colored DIP switches located on the 810LP’s bottom panel as shown above in figure 1. There are two (2) banks of DIP switches – The upper bank provides for the capacitance and resistance loading adjustments; the lower bank for gain level and equalization curve settings.
810LP Reference Dual-Mono Phono Preamplifier Cartridge Loading Adjustments Prior to making any of these adjustments, always disconnect the AC power cord and all interconnects from MOON 810LP. We strongly recommend using the pen shaped plastic hand tool that we have included with your 810LP as it was specifically designed for this purpose. Using another tool made from a material other than plastic may damage the DIP switches and/or scratch the painted surface on the bottom of the 810LP’.
810LP Reference Dual-Mono Phono Preamplifier Resistance Loading: There are sixty-four (64) unique resistance loading settings available using DIP switches 1 through 6, located at the bottom of the upper DIP switch bank. The range of available settings starts at 12.
810LP Reference Dual-Mono Phono Preamplifier Gain Setting: There are sixteen (16) unique gain level settings available using DIP switches 2 through 5, located at the top of the lower DIP switch bank. The range of available settings runs from 40dB all the way up to 70.0dB: Figure 4: Left and right channel DIP switches for gain level settings The factory default gain level setting is 40dB whereby DIP switches 5, 4, 3 & 2 are set to the right position (’OFF’).
810LP Reference Dual-Mono Phono Preamplifier Rear Panel Connections Figure 6: MOON 810LP Rear panel The rear panel will look similar to Figure 6 (above). All audio connectors are located on the left side of the rear panel.
810LP Reference Dual-Mono Phono Preamplifier The MOON 810LP is equipped with a 5-point version of our M-Octave Damping system, whereby the main audio circuit board is coupled to the chassis using an 5-point floating suspension that is designed to eliminate distortion caused by the “Microphonic effect” of airborne vibrations. All audio connectors are directly mounted to this main audio circuit board.
810LP Reference Dual-Mono Phono Preamplifier Remote Operation Figure 8: Remote Operation with 12V Trigger In figure 8 we have a 810LP Phono Preamplifier, 850P Preamplifier, and 870A Power Amplifier connected together via their respective 12V triggers; The two 12V trigger outputs on the 850P are connected to the 12V trigger inputs on both the 810LP (using a 1/8” mini-jack cable) and 870A.
