(i.e. volume control). Usually this is a headphone or pre-
amp output. However, as this varies from device to device
we recommend referencing your device's user manual.
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).

Speaker Level Connection

When using the Speaker Level connections do not
use the Line Level connection at the same time .
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
(see figure 2).
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, right, and
center 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 Feature utilizes a muting circuit that will detect such
anomalies and minimize them.
WARNING! Turn your amplifier off
before making or breaking any signal con-
nections!

Acoustic Contour Switch

Feature employs a unique 'on-wall/off-wall' switch that
tailors acoustic equalization to either installation option.
Simply set this switch to On-Wall if mounting to a surface.
Set the switch to Off-Wall if the Feature is more than four
inches from a wall. Setting this switch ensures that you will
achieve total system matching in even the most diverse
setups (such as systems mixing on-wall and off-wall instal-
lations).

Break-In

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