CONNECTING AND OPERATING THE
SUBWOOFER - METHOD 2
With other brands of front speakers
1. On the rear of the receiver there should be a single RCA type jack named
“Subwoofer Out” Connect a single RCA type audio cable from the “Subwoofer Out”
jack to the “Sub Input” (jack #2 on diagram #2)
2. Plug the Subwoofer’s AC cord into an AC outlet. Do not use the accessory type AC
outlets on the rear of the AV receiver.
3. Set the Low Pass Filter Control (knob #2 diagram #1) to match the model of speaker
that you have in the front of your system. The best way to start finding the correct
frequency is to set the control to the low level cut off of the front speakers. This
specification can be found in the owners manual of your speakers, or from the
manufacturer. This is just a starting point however as room acoustics, placement
and other variables dictate that you will need to experiment with this control to get
the sound of the subwoofer to blend with that of the front speakers.
4. Adjust the Volume Control (knob #1 diagram #1) to match the output of the system.
This can be done to suit your personal taste, and room size. Start somewhere in the
middle of the dial and adjust as you feel is necessary.
CONNECTING AND OPERATING THE
SUBWOOFER - METHOD 3
For LFE or Home Theater Applications
• The AS-P400/AS-P300 subwoofer features a secondary input called the “Direct
Input” (jack #1 on diagram #2). This is also known as a crossover bypass type input.
This is recommended for dedicated home theater systems only.
• When using this input, the Low Pass Filter Control (Knob #2 on Diagram #1) and the
Volume Control (Knob #1 on Diagram#1) are bypassed. This means that the
subwoofer will output its total possible frequency range, which is up to 120Hz. The
volume output of the subwoofer must be adjusted from the Bass Management
system built into your Audio Video Receiver.
Note: In music applications, use of the “Direct Input” can cause an overlap in
the bass response between the subwoofer and the front speakers, and usually a
“boomy” sound is the result. It is recommended to use connection Method 1 or 2
for systems where both music and home theater are being utilized.
1. On the rear of the receiver there should be a single RCA type jack named
“Subwoofer Out” Connect a single RCA type audio cable from the “Subwoofer Out”
jack to the “Direct Input” (jack #1 on diagram #2)
2. Plug the Subwoofer’s AC cord into an AC outlet. Do not use the accessory type AC
outlets on the rear of the AV receiver.
3. No adjustments to the Low Pass Filter Control (knob #2 diagram #1) or the Volume
Control (knob #1 diagram #1) are necessary as these controls are bypassed.
4. Adjust the Volume Control (knob #1 diagram #1) to match the output of the system.
This can be done to suit your personal taste, and room size. Start somewhere in the
middle of the dial and adjust as you feel is necessary.

High Level or Speaker Type Inputs
• These inputs are provided for use with receivers or amplifiers that do not have a
built in RCA type subwoofer jack. If your receiver has an RCA subwoofer type jack it
is recommended to use it, using methods 1, 2 or 3.
1. On the rear of your receiver, locate the Front Speaker outputs. Connect a pair of
speaker cables from the receivers front speaker outputs to the Speaker Inputs (jack
#3 diagram #2) on the AS-P400/AS-P300 subwoofer.
2. Using an additional pair of speaker cables, connect from the speaker outputs on the
AS-P400/AS-P300 subwoofer to the left and right front speakers.
3. Make sure that you carefully match the Positive to Positive and Negative to
Negative, on all speaker connections. Also make sure the left and right channels are
wired separately and correctly.
4. Plug the Subwoofer’s AC cord into an AC outlet. Do not use the accessory type AC
outlets on the rear of the AV receiver.
5. Set the Low Pass Filter Control (knob #2 diagram #1) to match the model of speaker
that you have in the front of your system. The best way to start finding the correct
frequency is to set the control to the low level cut off of the front speakers. This
specification can be found in the owners manual of your speakers, or from the
manufacturer. This is just a starting point however as room acoustics, placement
and other variables dictate that you will need to experiment with this control to get
the sound of the subwoofer to blend with that of the front speakers.
6. Adjust the Volume Control (knob #1 diagram #1) to match the output of the system.
This can be done to suit your personal taste, and room size. Start somewhere in the
middle of the dial and adjust as you feel is necessary.
