350P Preamplifier Introduction Thank you for selecting the Nēo 350P Preamplifier as a part of your hi-fi reproduction system. This preamplifier has been designed to offer state-of-theart 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 among the finest preamplifiers available.
350P Preamplifier Unpacking The Nēo 350P Preamplifier should be removed from its box with care. The following accessories should be included inside the box with your preamplifier: 9 AC power cable 9 ‘CRM-2’ remote control with two ‘AA’ batteries 9 This owner’s manual 9 Warranty and product registration information Once the Nēo 350P is unpacked, inspect it thoroughly and report any damage to your dealer immediately.
350P Preamplifier Front Panel Controls Figure 1: Nēo 350P Front panel The front panel will look similar to Figure 1 (above). The large display window indicates the selected input source. If your Nēo 350P includes the digital input option, additional information will appear in the display window. Refer to the section entitled “Optional Digital Inputs” on page 8 for further details. The “Standby” button disengages the input section from the rest of the 350P’s circuitry.
350P Preamplifier The “Mute” button mutes the output signal to the headphone jack, as well as both the fixed and variable line output connectors (refer to the section entitled “Rear Panel Connections” for further details). Pressing the “Mute” button a second time will reinstate the volume back to its previous level. When the output signal is muted, the red LED to the right will repeatedly flash on and off.
350P Preamplifier When you select one of the digital inputs as described in the aforementioned section, the display window will show which of the four digital inputs is selected. At the same time, the right side of the display window will initially show four dashes as follows “----” which indicate that the 350P is in the process of locking onto the external digital signal – this may take several seconds.
350P Preamplifier Internal Settings We strongly recommend that you ask your MOON Authorized Dealer to make these adjustements. If you decide to do this on your own, any damage cause to this component, including from static discharge, will not be covered under warranty. There are three (3) types of settings available on the optional phono section of the Nēo 350P; Capacitance loading, Resistance loading, and Gain level. Each setting is adjustable through the use of jumpers.
350P Preamplifier Rear Panel Connections Figure 4: Nēo 350P Rear panel The rear panel will look similar to Figure 2 (above). There are two (2) pairs of balanced analog inputs on XLR connectors labeled “B1” and “B2” with their respective left and right channel connections beside each other. Immediately below are four (4) pairs of single-ended analog inputs on RCA connectors labeled CD, A1, A2/HT and A3/PH.
350P Preamplifier Connect the supplied AC power cable to the IEC receptacle, located on the preamplifier’s rear panel. Ensure that the AC wall outlet you use has a functioning ground. For the best sonic performance, it is preferable that you plug your 350P directly into a dedicated AC outlet and avoid using an extension cord. If you have the time and willingness, consider installing a superior quality AC wall outlet such as a hospital grade Hubbell*.
350P Preamplifier Operating the 350P We recommend leaving your Nēo 350P powered up at all times to maintain optimal performance. When you plan on being away for a few days, it may not be a bad idea to power off your preamplifier. Please keep in mind that once fully “broken-in”, your 350P requires several hours of operation before reaching optimal performance after powering it up again.
350P Preamplifier Remote Control Operation The Nēo 350P Preamplifier uses the ‘CRM-2’ full-function remote control (figure 3). It operates on the Philips RC-5 communication protocol and is can be used with other Simaudio MOON components. The ‘CRM-2’ remote uses two AA batteries (included). To install them, simply slide the back plate off in the direction of the arrow; insert the batteries in the correct direction and then replace the back plate.
