QUICK-START GUIDE

SUBWOOFER REAR-PANEL CONTROLS AND CONNECTIONS

1) Crossover Control: This control determines the highest frequency at

which the subwoofer reproduces sounds. The higher you set the Crossover

control, the higher in frequency the subwoofer will operate and the more its

bass will “overlap” that of the speakers. This adjustment helps achieve a

smooth transition of bass frequencies between the subwoofer and the

speakers for a variety of different rooms and subwoofer locations.

2) Phase Switch: This switch determines whether the subwoofer

transducer's piston-like action moves in and out in phase with the main

speakers. If the subwoofer were to play out of phase with the main

speakers, the sound waves from the main speakers could partially cancel

out the sound waves from the subwoofer, reducing bass performance and

sonic impact. This phenomenon depends in part on the placement of all the

speakers relative to the listening position and to each other in the room.

3) Bass Boost: When switched to 'On,' this boosts bass level for added

low-end power.

4) Power On Mode: When switched to 'Auto' position, the subwoofer will

then be in Standby mode. It will automatically turn 'On' when an audio signal

is detected at its inputs, and will return to the Standby mode when no audio

signal is detected by its inputs after approximately 10 minutes. Otherwise,

subwoofer will always remain powered until Power Switch is turned 'Off.'

5) Subwoofer Level: Use this control to adjust the subwoofer’s volume. Turn

the knob clockwise to increase the volume; turn the knob counterclock-wise

to decrease the volume.

6) On/Standby LED: When the Power switch is in the ‘On’ position, this

LED indicates whether the subwoofer is in the On or Standby state.

• When the LED glows the subwoofer is in the Standby mode.red,

7) Line In/LFE Input Connectors:

• When you’re connecting the subwoofer to the dedicated subwoofer

output of a receiver/processor that has its own low-pass crossover

network, use the LFE Input connector.

• When you're connecting the subwoofer to the preamp or subwoofer

outputs of a receiver/processor that does not have its own low-pass

crossover network, use both Line In connectors and set the Input

Mode switch in the ‘Normal’ position. If your receiver/processor only

has one subwoofer output you can use either Line In connector.

8) Power Switch: Set this switch in the ‘On’ position to turn the

subwoofer on.

If you will be away from home, or will not be using the subwoofer for an

extended period, set this switch in the ‘Off’ position to conserve energy.

9) Power Cord: After you have made and veriﬁed the subwoofer’s input

connections, plug the power cord into an active, unswitched electrical outlet

for proper operation of the subwoofer.

DO NOT plug the power cord into the accessory outlets found on some

audio components.

PLACING THE SUBWOOFER

CONNECTING THE SUBWOOFER

The performance of a subwoofer is directly related to its placement in the listening room

and its physical position relative to the other speakers in the system.

While it is true that in general our ears do not hear directional sounds at the low

frequencies where subwoofers operate, when installing a subwoofer within the limited

conﬁnes of a room, the reﬂections, standing waves and absorptions generated within

the room will strongly inﬂuence the performance of any subwoofer system. As a result,

the speciﬁc location of the subwoofer in the room does become important to the

amount and quality of bass that is produced.

For example, placing the subwoofer next to a wall generally will increase the amount of

bass in the room; placing it in a corner ( ) generally will maximize amount of bass in the 1

room. However, corner placement can also increase the destructive effect of standing

waves on bass performance. This effect can vary depending on the listening position

– some listening positions may yield very good results while others may have far too

much (or too little) bass at certain frequencies.

We strongly recommend that you experiment with placement before choosing a ﬁnal

location for your subwoofer. One way you can determine the best location for the sub-

woofer is by temporarily placing it in the listening position and playing music with strong

bass content. Move around to various locations in the room while the system is playing

(putting your ears where the subwoofer would be placed), and listen until you ﬁnd the

location where the bass performance is best. Place the subwoofer in that location.

In many rooms, placing the subwoofer along the same plane as the left and right

speakers ( ) can produce the best integration between the sound of the subwoofer 2

and that of the left and right speakers. In some rooms, the best performance could

even result from placing the subwoofer behind the listening position ( ).3
