The MOON W-6 Mono power amplifier is a large and heavy component that should be removed from its box with care. We strongly advise that you seek another person to help lift the amplifier out of its box, and place it in its final location. The following accessories should be included inside the box with your amplifier: AC power cable 4 Pointed screw-on tips (for the amplifier’s legs) 1 “dummy” RCA termination plug This owner’s manual Warranty card (USA and Canada only) As soon as the amplifier is safely removed from its box and placed down, perform a thorough physical inspection and report any physical damage to your dealer immediately. We suggest that you keep the original packaging, and that it should be stored in a safe, dry place in case you’re required to transport the amplifier. The customized packaging is specially designed to protect the amplifier from potential damage that can arise when shipping such a product. ________________________________________________________________ WARNING! To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. Do not attempt to “lift the ground” by removing the ground pin from the AC cable. Make sure that your household electrical wiring supports proper AC grounding techniques before plugging in this product. Keep the heat sinks and top cover free of dust to allow for proper heat dissipation. Never expose this product to extreme temperatures. Always connect the audio signal path cables prior to connecting the AC mains. CAUTION! No user-serviceable parts inside. Do not remove top cover, as severe electrical shock may result. IMPORTANT! Make sure that your local AC voltage complies with the unit’s label. Damage caused by plugging thus amplifier into an AC receptacle of the wrong voltage will not be covered by warranty. ____________________________________________________________________________________ Unpacking and Warning 5 MOON W-6 Mono Power Amplifier Installation Tips The MOON W-6 Mono power amplifier is both powerful and heavy. It requires reasonable ventilation to maintain an optimum and consistent operating temperature. Consequently, it should be placed in a location with empty space around it for proper heat dissipation. You should never place another component on top of this amplifier. Also, it should sit on a solid hard surface to prevent any accidents such as falling over. This is a powerful amplifier and it will radiate heat when driven hard; You should avoid placing it near a heat source or inside a closed cabinet that is not well ventilated. This could compromise the amplifier’s performance and reliability. The W-6 uses two large toroidal transformers in its power supply. Even though they are well shielded, you should not place this amplifier too close to source components sensitive to EMI, such as turntables, phono preamplifiers and CD Players. Once you have decided on a location for your W-6, you should install the four (4) pointed screw-on tips onto the cones of the chassis. These tips will easily scratch most surfaces, therefore it’s advisable to follow these instructions: 1) Place your W-6 on a soft surface (i.e. carpet) and carefully turn it so that it rests on its side. 2) Screw one tip onto each of the four cones. 3) Carefully move your W-6 to it’s pre-determined location. Included with these tips is a small metal rod, intended for final adjustments (if necessary) by simply threading it through the tiny hole of each of these tips and then gently turning. These adjustable screw-on tips serve two purposes: Mechanical grounding of the chassis and compensation for surfaces that aren’t perfectly level. Since household dust is an excellent insulator of heat, we suggest that you clean both of the curved side-mounted heat sinks on a regular basis. A smooth nylon brush with long bristles (ie. paint brush) is recommended for this task. ____________________________________________________________________________________ Installation Tips 6 MOON W-6 Mono Power Amplifier Rear Panel Figure 1: Rear panel of Moon W-6 Mono Amplifier The rear panel will look similar to Figure 1 (above). There is one balanced input on an XLR connector and two single-ended (unbalanced) inputs on RCA connectors: one marked “+” and the other marked “-”. The reason for two single-ended RCA connectors is as follows: In the event that you wish to operate the MOON W-6 Mono power amplifier in balanced mode using RCA terminated interconnects. Furthermore, some preamplifiers invert phase and, as a result, their output signal requires phase correction; This can be accomplished by simply using the amplifier’s RCA input labeled “-”. Normally, you would run the single-ended interconnect from your preamplifier to the RCA input labeled “+” on the W-6’s rear panel. There is no switch to toggle from balanced mode to single-ended mode. You may operate the amplifier in either mode, but it is preferable to use the balanced mode to take full advantage of its capabilities. One pair of heavy duty gold-plated binding posts are located in the center of the rear panel with a “-” and a “+” terminal for the speaker output. On the far right side, you will find; The power “main switch”; The “AC Fuse” socket cover; and the “AC in” IEC receptacle for the power cord. ____________________________________________________________________________________ Rear Panel 7 MOON W-6 Mono Power Amplifier Connecting the W-6 1. Connect the input cable running from your preamplifier’s output, whether balanced or single-ended, to the amplifier’ s XLR or RCA input respectively. We highly recommend that you use the balanced XLR input (provided that your preamplifier has balanced outputs) to take full advantage of MOON W-6 Mono power amplifier’s capabilities. Please refer to the next section “Balanced Operation” on page 9 for further information. In the event that you are using a single-ended RCA interconnect, you should use the amplifier’s RCA female jack labeled “+” and leave the “dummy” RCA termination plug in the “-“ RCA female jack. If your preamplifier inverts phase, then your should use the RCA female jack labeled “-“ and insert the dummy RCA termination plug into the “+” RCA female jack. Don’t hesitate to use high quality interconnect cables. Poor quality interconnect cables can degrade the overall sonic performance of your system. It is recommended, though not mandatory, to use balanced interconnects between your preamplifier and the W-6 when using long cable runs (i.e. more than 3 meters in length). 2. Connect your speaker, with the cable of your choice, to the W-6’s speaker binding posts. Take care to respect the polarity (“+” , “-” ) of the output. Once again, don’t hesitate to use high quality speaker cables. Poor quality speaker cables can degrade the overall sonic performance of your system. 3. Connect the supplied AC power cable to the IEC receptacle, located on the amplifier’s rear panel. Alternatively, if you wish, you may use a dedicated high-performance AC cable designed for high current applications. Ensure that the AC wall outlet you use has a functioning ground. For the best sonic performance, it is preferable that you plug your W-6 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. 4. In order to obtain the maximum performance from your audio system, we strongly recommend that the detachable power cord not come into physical contact with either the interconnect cable or the speaker cable running to and from your W-6. In the event that this can’t be avoided, you should ensure that any cables coming into contact with each other are crossed at ninety degree angles to minimize the contact area. ____________________________________________________________________________________ Connecting The W-6 8 MOON W-6 Mono Power Amplifier 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 the amplifier and heard through the loudspeakers. Conversely, a balanced interconnect has three separate conductors; one for the ground and two for the actual signal. These two signals are identical except that one is 180 degrees out of phase with the other. For example, when one conductor is carrying a signal of +5 Volts, the other will be carrying a signal of –5 Volts. When these two inverted signals on a balanced line are input into a differential power amplifier such as the MOON W-6 Mono power amplifier, 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. You can operate the MOON W-6 Mono power amplifier in balanced mode one of two ways: 1) When using a balanced interconnect cable with an XLR connector, You must remove the “dummy” RCA terminator plug from the back panel and store it in a safe place. 2) You can also use both of the RCA “+” and “-” inputs for balanced operation. ____________________________________________________________________________________ Balanced Operation 9 MOON W-6 Mono Power Amplifier Operating the W-6 We recommend that you leave your MOON W-6 Mono power amplifier 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 amplifier may not be a bad idea. Once fully “broken-in”, please keep in mind that your W-6 will require several hours of playing time before it reaches its peak performance after you’ve powered it up again. Turning on your MOON W-6 for the first time Prior to turning the amplifier on for the first time, make sure that every cable is properly connected to avoid any problems. Then turn on your preamplifier connected to the W-6. Finally, power up your W6 in the following manner: 1) Flick the main rocker switch labeled “MAIN POWER” to the ‘1’ (on) position. 2) Next, momentarily press the push button mounted on the amplifier’s bottom panel, located behind the front faceplate’s left handed side. The amplifier will make a faint click sound, confirming that everything is in order. The blue LED on the front panel indicates that the amplifier is powered up and ready for use. On and Off Sequence To avoid having any annoying noises (ie. “thumps” and “pops”) emanate from your speakers when powering your W-6 on or off, you should 1) Always power up your preamplifier prior to powering up your W-6. 2) Always power down your W-6 prior to powering down your preamplifier. Troubleshooting Your MOON W-6 Mono power amplifier is equipped with a self-diagnostic system that will automatically shut itself down when it detects DC (direct current) from any input. If your W-6 power amplifier turns itself off or will not power up, there may very well be DC present in one (or more) of the amplifier’s inputs coming from one (or more) of your preamplifier/processor’s outputs. You must determine if there is any DC present. The best way to accomplish this is by first powering down the W-6 via the main power rocker switch, then disconnecting the input to the W-6 leaving only the speaker connected. Attempt to power up your W-6 again: A successful power up will indicate the presence of DC coming from your preamplifier or one of your signal sources (ie. CD Player). If your W-6 still doesn’t power up, turn off the main power switch and check the AC fuse. If the fuse appears OK, put it back in its socket and then try to power up again the usual way. If the fuse is blown, replace it with a fuse of the same rating, and repeat the above process. At this point, you should be able to power up your W-6. If not, immediately consult your dealer for assistance. ____________________________________________________________________________________ Operating The W-6 10 MOON W-6 Mono Power Amplifier Custom Installation 12 Volt Remote Trigger The “12 Volt Remote Trigger” can turn the MOON W-6 mono power amplifier on or off by a hard wired remote connected to its input. When correctly installed, the system allows the use of both the trigger and the push button to turn the W-6 on or off. Please note that the main rocker power switch must be left on at all times to allow for the use of the 12 Volt trigger. When the W-6 is powered off, it can be powered on by either the trigger or the push button. When the W-6 is powered on, it can be powered off by the trigger. It can also be powered off by the push button, but only if the trigger isn’t in «on» mode. Working with the 12 Volt Trigger The 12 Volt Trigger input is on a 3.5 mm microphone jack (mono) loacted on the back panel of the MOON W-6. With simple direct logic applied, 0V turns the unit off, and 12V turns the unit on. Input impedance is 300 ohms and the current required will be approximately 40 mA. Remember, the main rocker power switch must be left in the “on” position at all times to make use of the trigger possible. Recommendations If you are a professional custom installer, please take the time to carefully read this manual prior to starting any installations involving the MOON W-6 mono power amplifier. Pay particular attention to the “Installation Tips” section on page 6. If you intend to mount the W-6 in an in-wall cabinet or other closed environment, remember that you have to ventilate the amplifier properly to prevent overheating. ____________________________________________________________________________________ Custom Installation 11 MOON W-6 Mono Power Amplifier Specifications Configuration ...........................................
