FUSES Acoustat speakers Models Two/M and Three/M and Models Two/MH and Three/MH utilize slo-blo type fuse(s) in the audio signal path. The ModelsTw/M and Three/M with Magne-Kinetic 121 Interface, and Models Tw/MH and Three/MH with MagneKinetic 131 Interface utilize 3 amp slo-blow fuse. When replacing fuse(s) only those of similar value and type can be used or the warranty may become invalid. ASSEMB LY INSTRUCTIONS For Models Two/M & Three/M PLEASE READ COMPLETELY BEFORE YOU BEGIN TO ASSEMBLE YOUR SPEAKER SYSTEM! 1, Lay the speaker face up on the floor. CAREFULLY and SLOWLY! Dropping the\ speaker could rupture the diaphragm with trapped air. 2. Remove the three screws from the bottom of the speaker system. The screws are 2-1/2" in length, each with a flat washer. Set them aside. 3. Remove oneofthe bases from the base box. Place the base against the b\ ottom of the speaker. such that the front/top(name plate is on thefront -right handcornerof the base) of the base faces up, and the three holes line up with the three holes in the bottom of the speaker. Start all three long screw/washer assemblies (through the base holes) into the speakers frame, DO NOT TIGHTEN 4. Adjust the base so that there arof the base is flush with the rear of th\ e frame. lighten the three screws securely. 1

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
