Break-in Period
Allow several hours of listening time to adequately break-in the Impression Series
speakers. As the speakers break-in, the driver suspensions will loosen. e result
of break-in will be an increase in low frequency response, improved denition, and
increased clarity and detail.
Impression Series 1 Owner’s Manual
Care and Cleaning
To maintain speaker appearance, we recommend wiping them down with a clean damp
so cloth. To clean dust from the grille cloth, use a vacuum with a brush attachment.
Features
e Impression Series speakers feature poly-matrix cone bass drivers and aluminized
poly-matrix cone midrange drivers. ese rigid cones resist exing and contribute to the
accurate reproduction of the audio signal, providing higher overall sound quality.
A quality fabric dome tweeter is used for high frequencies in Impression Series
speakers. Higher power handling is achieved through the use of magnetic liquid
cooling in the tweeter. To protect the tweeter against being over driven, a polyswitch
(a current limiting device) is incorporated in the crossover network.
Each Impression Series speaker model features a crossover network to minimize
driver interaction irregularities and maximize the ability of each driver to accurately
reproduce its respective band of frequencies. Five-way binding posts ensure a solid
electrical connection to these crossover networks.
e Impression Series speakers’ cabinets are constructed of ½-inch medium density
berboard because of its inert properties, thereby minimizing sound coloration. e
front baes are double layered to 1-inch thickness helping to prevent excess acoustic
radiation from the cabinet.
Attaching Speaker Wires
If using a banana jack, attach the matching positive or negative wire and push directly
into binding post top hole.
If not using a banana jack, simply loosen the binding nut to allow the hole in the side
of the terminal to become exposed. Strip ¼-inch of the insulation from the end of
the speaker wire and insert the exposed wire end into the now exposed hole in the
side of the terminal. Tighten the binding nut by turning the nut clockwise until the
speaker wire is secured. Repeat for the other speaker wire(s) as necessary.

Room Setup Suggestions
In order to obtain the best possible sound from your speaker system, it is important to
determine where the speakers will sound best in your listening room. Room reections
from the oor, ceiling and side walls inuence the balance, imaging and overall sonic
quality at the listening position. Experiment with speaker placement to determine which
location oers the best overall sound. As a general guide, use the room layout diagram
and the following descriptions when setting up a home theater system. Some speakers
shown in the diagram may not always be applicable to your individual system.
Front Main Speakers
As a starting point, place your le and right tower speakers at least 15 inches from the
wall and 7-feet apart from each other. e distance from the listening position to each
speaker should be close to the distance that separates the two main speakers. Angling
the speakers inward towards the listening position may give a more spacious and
realistic sound stage.
Center Channel Speaker
e center channel speaker should be placed in the center between both le and right
main speakers. Oen this positioning dictates placing the speaker either directly above
or below a television monitor. e center channel speaker may be placed in a horizontal
(lying down) or vertical (standing) position.
Rear Surround Speakers
e 2-way bookshelf speakers may be placed either above, behind or to the sides of the
listening position. e listening position should be centered between the surround
speakers. For best performance you may want to experiment with angling the surround
speakers either towards or away from the listening position.
Subwoofer
In order to obtain the best possible sound from your subwoofer, it is important to
determine where the subwoofer will sound best in your listening room. Sound reections
from the oor, ceiling and side walls inuence the balance, imaging and overall sonic
quality at the listening position. Experiment with subwoofer placement to determine
which location oers the best overall sound.
Placement of the subwoofer will largely determine quality, quantity and extension of the
bass frequencies within your listening room. Bass frequencies are reinforced by close
room boundaries. Placing the subwoofer in a corner will make the subwoofer sound
louder and boost the very lowest frequencies.
Placing the subwoofer away from walls will provide the least reinforcement, making the
bass sound subjectively thinner than if the woofer were closer to a wall. Good results
can usually be obtained by placing a subwoofer along a wall 1-3 feet from a corner.
Experiment with placement of the subwoofer and the sub-amplier controls to achieve
the proper bass balance.
Impression Series 3 Owner’s Manual
Room Setup Suggestions (continued)
IMPORTANT NOTICE REGARDING BASS MANAGEMENT: It is important the signal
being sent to the subwoofer be a non-boosted or “at” signal. To be sure of this, check
the settings on your receiver or processor to make sure any “bass boost”, “super bass” or
“loudness” is set to O. In most cases a home theater receiver or processor will determine
the crossover frequency through bass management settings. In this conguration, connect
the receiver or processor to the Line Level Input. Your subwoofer will now reproduce the
bass frequencies the way they were originally recorded. Use the subwoofer level control
and the individual bass management control within the receiver or processor to adjust
the subwoofers’ volume if necessary. Once set, the volume controls should not need to
be altered as the subwoofers’ volume will track with the master volume control of your
receiver or processor.
NOTE: ere are several dierent surround formats avai lable. Dolby Pro-Logic, Pro-Log ic II, Dolby Digital and DTS generally
have a 5 speaker plus subwoofer requirement . Dolby Digital EX and DTS ES add a center rear speaker. Dolby TrueHD and DTS
Master Audio avai lable only on Blu-ray disc, generally have a 7.1 requirement. Please consu lt your audio/video profes sional to
determi ne which system is bes t for you and how many speakers you wil l require.

Subwoofer Safety Instructions
e lightning ash with the arrowhead symbol within an equilateral triangle, is intended
to alert the user to the presence of un-insulated “dangerous voltage” within the product
enclosure that may be of sucient magnitude to constitute a risk of shock to persons.
e exclamation point within an equilateral triangle is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in the literature
accompanying the product.
When using your subwoofer, basic safety precautions should always be followed to
reduce the risk of re, electric shock, and injury.
1. Read and understand all instructions in this users manual before operating the
subwoofer and retain this user manual for future reference.
2. Follow all warnings and instructions in this manual and any marked on the back
of the Subwoofer.
3. Never touch the woofer or push objects of any kind into the woofer.
4. e subwoofer should be connected to a power supply compatible with the power
consumption requirements, see the specications section of this manual.
5. If mounting the subwoofer on a stand, the wall, or other device only do so as
recommended by an authorized technician.
6. Place the subwoofer a safe distance from all heat sources such as radiators, stoves,
or heaters.
7. Do not operate the subwoofer near water—for example, near a bathtub, kitchen
sink or in a wet basement; or a swimming pool.
8. Power supply cords should be routed so they are not likely to be walked on or
pinched by items placed upon or against them.
9. Any service or repair required must be performed by qualied, authorized
technician.
Subwoofer Amplier Controls and Setup
is section describes the functions and/or use for each of the amplier controls
located on the back of the subwoofer. See the diagram of the back of the subwoofer
on the next page.
1. Voltage Selector Switch: Before connecting the amplier to any power source
make sure the AC Voltage Selector is set to either 110V or 220V to match the
power voltage in your area.
WARNING! If the voltage setting does not match the AC power supplied, damage
to the Subwoofer Amplier may result.
Impression Series 5 Owner’s Manual
Subwoofer Amplier Controls and Setup (continued)
2. Volume/Gain Control: e volume/level control should be at the minimum
setting (all the way counter-clockwise) before plugging the subwoofer into an
AC wall socket. Once plugged in, turn the level control up one quarter of a turn
(9 o’clock position) for an initial setting. e level control may be adjusted while
playing to match the subwoofer level with the rest of the system.
IMPORTANT! e volume control should be at the minimum setting (all the way
counter-clockwise) before plugging the subwoofer into an AC wall socket.
3. Crossover Frequency Control: The variable crossover frequenc y control
allows you to set the low-pass crossover point of the subwoofer anywhere from
40-180 Hz. If using this input experiment with setting the crossover frequency
control at highest setting initially. Increasing the crossover frequency will allow
more mid-bass output from the subwoofer. Decreasing the frequency will allow
only deeper bass from the subwoofer.
NOTE: Read the Important Notice regarding bass management on page 4.
4. Auto Signal Tracking: e subwoofer amplier uses “smart” signal tracking circuitry.
Once the power cord is plugged in and the switch set to auto, the amplier automatically
turns on when a signal is detected at the preamplier or high level inputs and turns o
when no signal has been detected for 15 minutes.
5. Phase Control: is control changes the phase of the subwoofer. Changing the
phase will change the way the subwoofer and main speakers interact with each
other at the crossover frequency. Varying the phase position may result in more
or less mid bass depending on the phasing between the main speakers and the
subwoofer. Generally, the phase is le at the “NOR (Normal)” position.
6. Low Level Line Output: ese RCA terminals are for “daisy chaining” to another
subwoofer or amplier. A full-range signal is sent through these terminals.
7. Low Level Line Input: Line level input is used to connect to most receivers or processors,
use either the L or R terminals.
8. Hi-Level Input: ese binding post terminal connections are for the amplier/
speaker level input from an amplier or receiver.
IMPORTANT! Use either the Line Input or the High Level Input. DO NOT
use them both simultaneously.
9. Hi-Level Output: is is a 100 Hz high-passed output for your satellite/main
speakers. e crossover limits the low frequencies (below 100 Hz) from going to
your satellite/main speakers. is crossover is active only when using the Hi-Level
Input terminals. Connect your main speakers (observing the proper polarity) to
these terminals when using the Hi-Level Inputs.

10. Fuse Access: is is the power fuse access.
WARNING! In the event the fuse must be replaced, the replacement fuse must
match exactly the original fuse value. If the replacement fuse is not of the same
value, damage to the Subwoofer Amplier may result.
CAUTION! Before replacing the fuse, disconnect the power cord from the
power receptacle.
11. Power: Power on and o switch.
