ASSEMB LY INSTRUCTIONS
For Models Two/M & Three/M
PLEASE READ COMPLETELY BEFORE YOU BEGIN TO ASSEMBLE YOUR SPEAKER SYSTEM!

2. Remove the three screws from the bottom of the speaker system. The screws are 2-1/2" in length,
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
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

Acoustat speakers are designed topreserve thecorrect absolute phase throughout the system, including
final coupling of the signal to the air. This ensures that both vocalists and instruments will sound
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.
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!
to switched outlets is not recommended. DO NOT exceed fuse ratings or bypass fuse
of the above conditions will result in damage to the low frequency transformer if the
Is overdriven. requiring an expensive repair not covered by,the warranty.
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.
