1. To avoid having any annoying noises i e thumps and pop or off you should emanate from your speakers when powering your ROCK on 1 Always power up your preamplifier prior to powering up your ROCK 2 Always power down your ROCK prior your powering down your preamplifier Using the 12 Volt Trigger When the ROCK is off it can be powered on by either the trigger or the push button When the ROCK is on it can be powered off by the trigger It can also be powered off using the push button but only if the trigger isn t in on mode The MAIN POWER switch must remain in the on position 1 at all times for the 12 V trigger to function Troubleshooting Your MOON ROCK 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 ROCK 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 ROCK via the main power rocker switch then disconnecting the input to the ROCK leaving only the speaker connected Attempt to power up your ROCK again A successful power up will indicate the presence of DC coming from your preamplifier or one of your signal sources i e CD Pla2.

7. ned 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 ROCK 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 ROCK 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 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 i e 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 in
