THE SOLlD LlNES ARE SHOWN TO FAClLITATE ANGLlNG ONLY.WHEN THE PANELS ARE\ PERPENDICULAR TO THE RESPECTIVESOLID LINETHAT APEX IS ACHIVED THE DASHED LINES REPRESENT THE SONIC RADIATION OF THE SPEAKERS. \ I " B NOTE SPEAKERS SHOWN ARE DRAWN WITH THE FROM PLANE OF THE SPEAKER PERPENDICULAR TO THE LISTENER. IN A ROOM THIS SEI-UP WOULD YIELD THE APEX IN THE B POSITION TO ACHIEVE ME APEX IN POSITION A THE SPEAKERS WOULD HAM TO BE ANGLED IN SLIGHTLY. PHASiNG Acoustat speakers are designed topreserve thecorrect absolute phase throughout the system, including the final coupling of the signal to the air. This ensures that both vocalists and instruments will sound as natural as possible. Phasing depends on the correct connections from the interface. Be sure these connections are correctly oriented, I.e. red (+) to red, and black (-) to black. ELECTRIC FEEDBACK Electrostatic speakers produce a strong electric field which can influence the operation of any low level electronic circuitry in close proximity This can result in feedback well above the audio spectrum, which has the effect of power dissipation and decreased headroom in the system. For this reason the turntable/cartridge leads and the phono lnputs of the preampilfier should be kept at least sixtoeightfeet from the nearest speaker to ensure that no feedback can occur. WARNING! DO NOT apply audio signal to the interface wlth the AC Power removed, hence no panel bias! Connection to switched outlets is not recommended. DO NOT exceed fuse ratings or bypass fuse receptabie. Either of the above conditions will result in damage to the low frequency transformer if the interface Is overdriven. requiring an expensive repair not covered by,the warranty. 7

CLEANING Speaker cloth may be cleaned with any commercial cleaning fluid, or anycleaner designed to be used with polyester knit fabrics. Use a cleaner such as K2R for small concentrated spots. REMOVAL OF INTERFACE FOR MODELS TWO/M & THREE/M WARNING ALWAYS UNPLUG THE LINECORD BEFORE REMOV NG THE INTERFACE! If the interface must be removed from the speaker, the following procedure isnecessary to discharge the panels 1, UNPLUG the interface from the AC outlet and dlsconnect the speaker leads from the amplifier. 2. CAREFULLY, lay the speaker on the floor. DROPPING IT CAN RESULT IN DAMAGE! 3. Unbolt the interface. 4. Set the interface on the floor behind the speaker, king careful not to unplug the three wire groups from the speaker 5. Remove the center RED pin plug. Hold the wlre an Inch behind the pin and GENTLY pull. DO NOT GRAB THE PLUG! Touch the RED tlp to either the BLUE or the WHITE terminal on the circuit board 6. Loosen the two thumbscrews and remove the hooks WARNING: High static voltages are present in the charged panel. Failure to follow these procedures will result in an annoying, but harmless electrical shock. REMOVAL OF HYBRID MODULE FOR MODELS TWO/MH & THREE/MH WARNING ALWAYS UNPLUG THE LNE CORD BEFORE REMOVlNG THE HYBRID MODULE! If the Hybrid Module must be removed from the speaker, the following procedure is necessary to discharge the panels 1, UNPLUG the Hybrid Module from the AC outlet and disconnectthe speaker leads from the amplifier. 2. CARERILLY, lay the speaker on the floor DROPPING CAN RESULT IN DAMAGE! 3. Unbolt the Hybrid Module, both thetwoscrewson the top of the module, and the threescrewsonthe 4. Set the module on the floor behind the speaker, being careful not to unplug the three wire groups 5. Remove the plastic insulator cover from the Hybrid Module. 6. Remove the center RED pin plug. Hold the wire an inch behind the pln and GENTLY pull. DO NOT GRAB THE PLUG! Touch the RED tipto either the BLUE or the WHITE terminal on the circuit board 7. Loosen the two thumbscrews and remove the hooks. 8. Replace the plastic insulator cover WARNING High static voltages are present in a charged panel. Failure to follow these procedures will result in an annoylng. but harmless shock. bottom of the speaker frame. from the speaker. LIMITED WARRANTY Amustat Corporation warrants to the owner that the Amustat loudspeaker system excluding the Dynamic Woofer. will perform as specified and that it will befreeofdefectsin materialsand workmanship for a period of FIVE YEARS from the date of origlnal manufacture. 8
