MOON P 5.3 Stereo Preamplifier Congratulations! Thank you for selecting the MOON P5.3 Stereo 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 two-channel Stereo Preamplifier available.
MOON P 5.3 Stereo Preamplifier Introduction Your MOON P5.3 Stereo Preamplifier incorporates many significant design features to achieve its “world class” level of performance.
MOON P 5.3 Stereo Preamplifier Front Panel Controls Figure 1: MOON P5.3 Front panel The front panel will look similar to Figure 1 (above). The large display window indicates the relative gain setting (ranging from ‘0’ through ‘50’) for both the left and right channels. As well, whenever you change the selected input source, it’s number will appear in the window for 3 seconds before reverting back to the gain setting.
MOON P 5.3 Stereo Preamplifier Front Panel Controls (continued) Pressing the “Mute” button reduces the current volume to “0”. Pressing the “Mute” button a second time will reinstate the volume back to its previous level. The rotary “volume” control determines the gain setting, which ranges from ‘0.0dB’ (no output) to ’50.0dB’ (full output).
MOON P5.3 Stereo Preamplifier Optional Phono Section The MOON P5.3 Stereo Preamplifier features an optional phono section that may be installed only at an authorized dealer or at the Simaudio factory. Circuit Board Layout: Figure 2: MOON P5.
MOON P5.3 Stereo Preamplifier Optional Phono Section (Cont’d) Internal Settings There are three (3) types of settings available on the optional phono section of the MOON P5.3 Preamplifier; Capacitance loading, Resistance loading, and Gain level. Each setting is adjustable through the use of jumpers. For each type of setting, there are 2 banks of jumpers – one each for the left and right channels.
MOON P 5.3 Stereo Preamplifier Rear Panel Connections Figure 3: MOON P5.3 Rear panel The rear panel will look similar to Figure 3 (above). There are four (4) pairs of single-ended inputs on RCA connectors labeled A2, A3, A4 and A5. The left channel inputs are located on top and the corresponding right channel inputs are located directly below. To the left of these single-ended inputs is one (1) pair of balanced inputs labeled A1. The MOON P5.
MOON P 5.3 Stereo Preamplifier Operating the P5.3 We recommend that you leave your MOON P5.3 Stereo Preamplifier powered up at all times to maintain optimal performance. In the event that you plan to be away from your home for a few days, powering off the Stereo Preamplifier may not be a bad idea. Once fully “broken-in”, please keep in mind that your P5.3 will require several hours of playing time before it reaches its peak performance after you’ve powered it up again.
MOON P 5.3 Stereo Preamplifier Balanced Operation When using an unbalanced interconnect, the audio signal runs through both the center wire and the shield/ground wire. Any noise picked up by this interconnect (ie. nearby magnetic fields such as an AC power cord) will be reproduced by both the preamplifier and amplifier, then heard through the loudspeakers. Conversely, a balanced interconnect has three separate conductors; one for the ground and two for the actual signal.
