R 500 Series THX Select System Owners' Manual MATERIAL Downloaded from www.Manualslib.
INTRODUCTION & CONTENTS Congratulations on your purchase! This 500 Series THX Select System is the result of an extensive Research and Development program undertaken to provide you with accurate, uncompromised reproduction of movie soundtracks and music. With attention to detail second to none, these loudspeakers not only guarantee outstanding enjoyment but their elegant, clean lines also allow them to integrate easily into the home.
A BRIEF INTRODUCTION TO HOME THX Incorporating a series of patented electronic and loudspeaker developments, home THX is the ultimate in sound for multi-channel home cinema systems. The system was developed after it was realised that conventional audio components could not satisfactorily reproduce movie soundtracks in the home environment.
GETTING STARTED Connecting your MS500 THX Select System Please do not compromise the performance of your system by using inferior quality cables. Mordaunt-Short recommends that high quality cables of 16 gauge or higher be used. Your professional dealer will give you good advice. There are two pairs of terminals on the rear of every speaker which permit bi-wiring if desired. For standard (non bi-wire) cable connection, leave links in place and use either pair of terminals (fig. 1).
GETTING STARTED Attaching feet to your loudspeakers Our floorstanding loudspeakers come with feet and spikes that will greatly improve stability and sound quality. The spikes attach to the bottom of the feet with the aid of a threaded guide (fig. 3) There are eight pilot holes on the bottom of the speakers. The feet are located and secured here with the wood screws supplied (fig. 4). Level as required.
MS502 INTEGRATED SUBWOOFER AMPLIFIER Each of your MS502’s have a built in dedicated subwoofer amplifier specially designed to deliver powerful low frequencies to the sub-woofer drive unit mounted on the side of each MS502. This integrated system gives the best possible bass reproduction with the minimum of adjustments and makes a separate subwoofer unnecessary. The controls are explained here. 1. 2. 3. 5. 4. 6. 8. 7. 1.
MS502 INTEGRATED SUBWOOFER AMPLIFIER 5. Volume This control allows you to adjust the volume of the low frequency output of your sub woofer amplifier for best sound-balance. This adjustment is defeated in THX mode as THX approved surround-sound processors allow subwoofer level adjustments to be done by the processor. 6. Notch Filter This is a single band Parametric EQ that is a powerful tool to help your loudspeaker system sound it’s best.
SUBWOOFER TUNING FOR OPTIMUM SOUND QUALITY Your MS500 system incorporates subwoofers built into the left and right front speakers to generate substantial amounts of low-frequency energy for a satisfying bass response. In addition the M500 system has been designed to give a substantially flat frequency response. However, the dimensions of some rooms and the positioning and nature of furniture can cause the bass response to be uneven.
TAKING CARE OF YOUR LOUDSPEAKERS 9. Should more than 6dB of cut be required (i.e. one measurement is more than 12dB above the average of the others) the notch filter can be set to the –12dB setting and the process repeated. Driver Precautions By far the most common cause of loudspeaker failure, and one that is understandably not covered by guarantee, is damage to the voice coils caused by amplifier overload.
SAFETY PRECAUTIONS Checking the Power Supply Setting Plug Fitting Instructions (UK only) For your own safety please read the following instructions carefully before attempting to connect your MS502 unit to the mains. The cord supplied with this appliance is factory fitted with a 13A mains plug fitted with a 3A fuse inside. If it is necessary to change the fuse, it is important that a 3A one is used.
