H YSIKS 4 LOUDSPEAKER PLACEMENT AND SET UP NOTE DO NOT place the loudspeakers close to cathode ray type monitors or projectors as the very powerful magnets used in the drivers may affect the picture We recommend a minimum separation of 2m Adjusting the Spikes NOTE We strongly recommend having an assistant help to hold the loudspeakers while the spikes are being adjusted The base of the Carbon Mk IV is fitted with four spikes These are double ended as shown in figure 5 and are locked in position with a nut You will need an open ended 10mm spanner to adjust them figure 6 AA AANA NANA RD KRAAN Na alala t Figure 5 Double Ended Spike and Nut The round ends of the spikes should be used when the loudspeakers are to be placed on a hard floor such as tile or wood and the pointed ends should be used when the loudspeakers are to be placed on a carpeted floor The loudspeakers are shipped with the round end of the spikes facing out When placing the loudspeakers on a carpeted floor ensure that the spikes are set to protrude sufficiently from the base to pass through the carpet and make firm contact with the underlying floor The easiest way to adjust the spikes is to lay the loudspeaker on its side To protect the finish we suggest that you use a clean soft blanket to lay the speaker on Set the two spikes at the back and the left hand front spike to protrude approximately the same amount within 1 or 2mm and then
7. NOTE NEVER attempt to clean the dust off the diaphragm Dust has no affect on its performance and may be safely ignored NEVER attempt to clean the speakers with any abrasive materials or any cleaners containing ammonia alcohol or other solvents as these may damage the finish The only maintenance the speakers will require is periodic dusting to remove dust and any finger prints from the cabinets Please use the cleaning cloths supplied with the loudspeakers These cloths should be used dry Do not use any form of liquid with them Additional cloths may be obtained via local your German Physiks dealer national distributor or direct from German Physiks 8 WARRANTY German Physiks loudspeakers are warranted to be free from defects if used under normal conditions for a period of 5 years from the date of purchase provided that the customer registers their purchase by completing and returning the registration form at the end of this manual within 7 days of purchase A copy of the receipt issued at the time of purchase must also be returned If this is not done the warranty period will be 5 years from the date of shipment from the factory This warranty is transferable to subsequent owners who must register their purchase with us Modifications or repairs performed by the factory or by an authorised repair agent shall be guaranteed for the remaining period of the warranty or for 1 year which ever is greater Any unauthorised modifications or

9. ecommend that you use loudspeaker cables terminated with high quality spade lugs as these provide the best electrical connection The lugs should be either soldered or crimped to the loudspeaker cable the latter is preferred We do not recommend the use of bare wire to connect to the loudspeaker terminals This produces an inferior connection that will further degrade as the bare conductors become tarnished 6 LOUDSPEAKER BREAK IN Like all audiophile equipment German Physiks loudspeakers require a break in period from new before they reach their optimum level of performance Initially the sound may seem harsh Please do not be concerned The sound will become more relaxed and smooth as the break in progresses The music used for the break in should be dynamic in order to properly exercise all the components of the loudspeaker For the first 10 hours play the loudspeaker at low level only This is a level where you would easily be able to carry out a conversation without needing to raise your voice After this the speaker may be played at normal listening levels The break in process will be complete after 200 to 300 hours 7 CARE OF YOUR LOUDSPEAKERS NOTE NEVER attempt to open the cabinets There are no user serviceable parts inside the loudspeakers NEVER touch the diaphragm on the DDD driver or allow any object to come into contact with the diaphragm 11 a ea ATS AAT l DDD MANUFACTUR GMBH PHYSIKS

12. it may be advantageous to place a carpet on the floor covering the area between the loudspeakers and the listening position as this will reduce unwanted early reflections 5 Avoid having the listening position closer than 1 2m from the rear wall as early reflections from this wall will degrade the stereo image amp GERI AAT il F e DDD MANUFACTUR GMBH PH YSIKS Loudspeaker Placement Distance from Front Wall We recommend that you start with the speaker positioned 1 5m from the front wall As you move the loudspeaker closer to the wall the level of the bass response will be increased The converse will be true as you move the loudspeaker away from the front wall The Carbon Mk IV should not be placed closer than 1m from the front wall If the loudspeaker is too close to the front wall not only will the bass response be excessive but the stereo image will be degraded due to an increase in early reflections Aim to find a position that provides an even bass response so that all the bass notes in the music are reproduced at an equal level combined with well a focussed stereo image when you are seated at the listening position Be sure to choose a recording that has an even bass response Distance from Side Wall We recommend that the distance between the centres of the loudspeakers be 2 3 of the distance of the loudspeakers from the listening point Moving the speakers further apart will degrade the stereo image We
