Please note: When making or breaking connections
from devices that utilize the Line Level input a popping
noise may occur. This is caused by grounding and static
discharge interaction. It is normal and to be expected when
using this method of connection. If a cable is connected to
the speaker, but is left unterminated at the device end you
may also experience a low-level hum. To minimize these
intermittent noises we recommend using a device that is per-
manently connected (such as a digital music player docking
station).

Use spade connectors for optimum contact and ease of
installation. Hand tighten the binding posts, but do not
overtighten—do not use a tool to tighten the binding posts

Be consistent when connecting the speaker cables to the
signal input terminals. Take care to assign the same color
cable lead to the (+) terminal on both the left and right
channel speakers. If bass is nonexistent and you cannot
discern a tight, coherent image, you may need to reverse
the (+) and (–) leads on one speaker to bring the system
into proper polarity.

Please note: When using the speaker level inputs a
popping noise may occur when the amplifier is turned on
or off. This is caused by grounding interaction between the
speaker and the amplifier. It is normal and to be expected.
The Purity features a built in muting circuit that will detect
such anomalies and minimize them.

Bass Level Control
On the rear panel of the Purity electronics module is a three
position Bass Level switch that allows you to select the type
of low frequency response you desire.

of low frequency response you desire.
The flat position is considered the normal setting for most
rooms. However, if you feel that the bass in your system
is too light or heavy relative to the mid and high frequen-
cies, simply select the +3dB or –3dB position to adjust the
woofer output.

Some experimentation with these switch settings will allow
you to find the optimal tonal balance for your specific taste,
room and equipment.

Break-In
When you begin to play your speakers, they will sound
a bit bass shy. This is due to the high quality, long-life
components used in our woofers. Our custom made, butyl
surround woofer requires approximately 72 hours of break-
in at 90 dB (moderate listening levels) before any critical
listening. The break-in requirements of the crossover com-
ponents and the electrostatic stator are equivalent.
