Acoustic Audio PSW250-6 Home Theater 6.5 LFE Subwoofer

Introduction

Congratulations on your purchase! Your new Acoustic Audio powered subwoofer was designed and manufactured to deliver refined musical reproduction and vivid home theater entertainment. Acoustic Audio products are constructed using the finest quality components and we are proud of our custom-designed drivers and electronics. Much effort has gone into the design of your new sub as to help you achieve years of maximum performance and listening pleasure. Every Acoustic Audio loudspeaker undergoes rigorous testing and quality controls at the factory to ensure years of listening pleasure. Please take a moment to read this manual prior to installing your new subwoofer. The information provided will help you obtain maximum performance.

Though this manual will refer to your receiver, the instructions and recommendations apply to all consumer amplifiers as well as AV receivers. Acoustic Audio powered subwoofers are designed for indoor use only.

IMPORTANT: It is important to turn off the power to your receiver’s power supply before connecting the subwoofer to your system.

Placement

Your Acoustic Audio subwoofer can be placed in many convenient locations in your home but must be placed on the floor. Do not attempt an installation that would elevate the subwoofer above floor level. You should experiment with various placements. Small changes in the placement location and adjustments to subwoofer controls can produce large apparent differences for room acoustics. For example, directing the woofer of a forward firing sub toward one’s typical listening position and adjusting the low pass filter to 140 Hz can make the sub very directional. This means you perceive exactly where the sub is located within the room. This is not a desirable result for the most realistic audio experience.

The common thinking regarding subwoofer placement and performance is to position and adjust the subwoofer in such a way that the subwoofer’s low frequencies encompass the entire room with deep powerful bass and provide the most realistic theater experience. The amount of bass perceived increases as you move the subwoofer closer to an intersecting wall surface and the highest level of bass results are realized from placement in a corner but should be no closer than 3″ from the wall surface. The floor and corner placement are actually an important part of the subwoofer’s design. Attempt to place the subwoofer in or near the corner closest to your system’s receiver to ensure the shortest possible wire or cable runs, which will result in superior performance.

Connecting Speakers

Connecting & Adjusting Your Subwoofer

When you make connections, make sure that the power switches of all components, including subwoofer, are OFF.

Power Cord

The attached power cord is to be used with a standard AC wall outlet (110 Volt AC outlet capable of supplying at least 250 Watts) Power Indicator LED

The LED light glows RED when the subwoofer is OFF or in standby mode. When the subwoofer is ON or receiving an audio signal in Auto On mode the LED will glow green.

Power Switch

The subwoofer has an Auto On feature for your convenience. When the subwoofer is set in the Auto On mode it is not necessary to power your subwoofer completely off when not in use. In Auto On, the subwoofer stands by until it detects an audio signal input, then the subwoofer turns on automatically. A few minutes after audio input signals cease, the subwoofer automatically returns to stand by mode. The subwoofer has been designed in such a way that you can leave the Auto On feature active without causing any harm to your subwoofer.

Fuse

The fuse protects against minor internal and external faults. The fuse value is indicated on the rear amplifier plate near the fuse itself. If the Power switch is ON and the Power Indicator LED is unlit, unplug the power cord from the AC outlet and check the fuse by unscrewing the center piece from the holder. IMPORTANT: If the fuse malfunctions, replace it with another fuse of the same type, value and current rating. This information can be found on the fuse.

Line- In Jacks

Option 1: This jack is for input connection using an audio cable (low level) See options 1 & 2 descriptions on the following page

Speaker – In Terminals

Option 2: These terminals are for making connections using speaker wire (high level)

Low Pass Frequency (LPF) Crossover

This feature adjusts the frequency limit for low audio signals. This control helps you adjust the system’s low frequency balance to blend your subwoofer with the other speakers within your system. An example: if you adjust the control to the subwoofer’s low setting, the filter limits frequencies above that from being reproduced or heard from the subwoofer. This can be a desired setting if you are using the sub in combination with tower or floor-standing speakers. If you are using satelite speakers with 5.25″ cone sizes or under, you will want to move the frequency up to slightly overlap the lowest frequency the satellites can produce. For example, if your satellite frequency response is rated at 80Hz to 18 kHz then you may choose

to move the LPF control higher to blend the highest frequency of the subwoofer slightly past the lowest frequency of the satellites. Therefore you would set your sub’s LPF control to 90Hz creating a mid bass coupling between your sub and th rest of your speaker system.

Volume Control

Balances the loudness of the subwoofer relative to the front speakers and compensates for room effects on the subwoofer’s output. It should not be necessary to set the level control to maximum volume to achieve a well balanced installation, but you may need to adjust when changing between CD’s, media and DVD’s.

IMPORTANT:

Use Option 1,2 OR 3 but none at the same time.

Option 1: Connection with Audio Cable -(recommended) This connection employs a left/ right audio cable. To use this option, your receiver should include a Subwoofer Outjack, which is typical of receivers with digital decoding. Make sure the Subwoofer Out on the receiver is on. Locate the subwoofer output jack on the back of your receiver. Using a standard audio cable, connect the subwoofer output on the back of your receiver to the line-in on the back of the subwoofer. If your receiver is equipped with only one subwoofer out jack, a Y splitter adapter may be required. Most models include this adapter. See Option 1 Diagram.

Option 2: Connection with Speaker Wire – Connect speaker wires from the receiver’s front left and right speaker outputs to the subwoofer’s speaker Level-In connections. Connect left channel to left input and right channel to right input. You have the option of connecting your main speakers to the speaker B outputs on your receiver if it is so equipped. Otherwise, if so equipped you have the option of connecting to your main speakers using the connections on the subwoofer. This will send the audio signal to the main speakers while funneling the low bass frequencies to the subwoofer. To take advantage of this option,connect your main speakers to the right and left outputs on the subwoofer. Be sure to maintain proper signal polarity by connecting the red wire to the red terminal and black wire to the black terminal. See Option 2 Diagram.

Note: Acoustic Audio recommends you use at least 16 gauge speaker wire for Option 2 when hooking your receiver speaker outputs in making an audio connection to your subwoofer.

Wiring Diagrams

Option 3: Connection with LFE – The subwoofer is equipped with a double insert RCA cable. Since the RCA cable has 2 inserts on each end and only one input on both the subwoofer and one output on the receiver, you may easily pull the cable in half making a white side and a red side. Use either the red or white side, both will work. Connect the LFE output on the receiver to the LFE input on the back of the subwoofer using the newly single RCA cable. Connect speaker wires from the receiver’s front left and right speaker outputs to the speaker’s inputs. Connect the left channel to the left input and right channel to right input. This will send the audio signal to the main speakers while funneling bass frequencies to the subwoofer. Be sure to maintain proper signal polarity by connecting the red wire to the red terminal and black wire to the black terminal. See Option 3 Diagram.

Troubleshooting

Distortion/ Knocking:
If you believe you hear obvious distortion or knocking sounds, immediately lower the volume level of your receiver. Those sounds often indicate that either the receiver or the subwoofer is being overdriven and damage can result in playing CD’s, DVD’s or media at high volumes. You should avoid turning the bass to maximum levels and refrain from using the loudness button when the volume level is high. This can lead to costly loudspeaker failure. Distorted or unnatural sound can also indicate poor connections. Check the connections. If the sound remains poor or distorted, the subwoofer may have a problem.

Hummin Sound
If you experience a hum when plugging the power cord into an electrical outlet, you are experiencing an electrical interference in your home’s wiring. Plug the subwoofer into a different AC outlet in the room, one that isn’t supplying power to your components (AV receiver, TV, cable box, etc.) You should also invest in a set of quality RCA cables that are shielded from electrical interference.

No Power

If your unit will not power ON the first step is to check the fuse. If the POWER switch is ON and the power indicator LED is unlit, unplug the power cord from the AC outlet and check the fuse by unscrewing the centerpiece from the holder. If the filament is broken the fuse must be replaced. IMPORTANT: If the fuse malfunctions, replace it with another fuse of the same type, value and current rating. This information can be found on the fuse.

No Sound
Make sure your unit is on. Using your receiver’s adjustment settings set the Subwoofer Out setting to ON and set speaker mode to your corresponding speaker setup (IE: 5.1 channel).

Sub Shuts Off
If your subwoofer keeps shutting off or is getting hot, be sure to check your wiring for correct connections. Also make sure the speaker wires are in phase(+ to +, – to -) and that no speaker wires are touching one another. These conditions will create an overload on either your receiver or your powered sub. The powered sub has built-in circuitry to detect any improper signal transfers and will automatically shut the unit down.

FAQs

On the Acoustic Audio PSW250-6 subwoofer, should LFE be used?

You must use the LFE/. 1 input when using a REL subwoofer in a home theatre system. The subwoofer/LFE/.1 output of the processor or receiver must be connected.

How can I connect my receiver to my Acoustic Audio PSW250-6 LFE subwoofer?

Your subwoofer’s connection to your home entertainment receiver is simple: Simply connect this audio connector cable to the receiver’s subwoofer output and the subwoofer line input of the subwoofer (pictured above). Whenever the subwoofer has an LFE input, use it.

What is the LFE subwoofer output of the Acoustic Audio PSW250-6?

The LFE channel is used to convey additional bass information in the surround sound programming, whereas the subwoofer output is bass information from up to all six channels that has been selected to be replayed by the subwoofer using a bass management system.

Do all PSW250-6 subwoofers from Acoustic Audio have LFE?

Almost all AV receivers and pre-amplifiers come equipped with LFE (Low-Frequency Effects) outputs as a standard feature. The LFE channel, which is a mono signal, has already been filtered before being sent to the subwoofer. Almost all subwoofers will have an LFE mode.

What does subwoofer LFE input for Acoustic Audio PSW250-6 mean?

The Low-Frequency Effects (LFE) channel on subwoofers is referred to as LFE input. You have a port where you can use the LFE input channel to connect your subwoofer to a receiver. Most subwoofers available today only have one LFE input channel.

Why does the subwoofer in my Acoustic Audio PSW250-6 have two inputs?

Dual input can boost the sensitivity of the subwoofer. Typically, using the processor’s mono LFE subwoofer signal would be sufficient. If your processor has a very low output, you can utilise a Y-splitter. The same mono signal delivered to both inputs doubles the sensitivity of the subwoofer.

Is LFE the same as the subwoofer out on the Acoustic Audio PSW250-6?

The LFE channel is used in the Dolby Digital program to convey additional bass information in contrast to the subwoofer output, which represents how all or some of the bass information will be reproduced.

Why are there 4 cables on my Acoustic Audio PSW250-6 subwoofer?

Speakers have four terminals that allow for bi-wiring connections. Split connections are possible with four-terminal speakers, which separate the speaker into two parts. The mid and high-frequency drivers utilize one set of terminals, while the low-frequency drivers use the other set.

What is the Acoustic Audio PSW250-6 high-level input subwoofer?

Subwoofers with high-level inputs connect to the terminals on your left and right speakers (speaker-level outputs). By doing this, the subwoofers and speakers both receive the exact same audio signal at the same time (they are perfectly synced).

Can I connect the subwoofer from Acoustic Audio PSW250-6 to the pre-out?

Connecting your powered subwoofers to a pre-out is rather simple. Simply use an RCA-type input jack to connect your receiver to your subwoofer to achieve this.

How far away from speakers should I place my Acoustic Audio PSW250-6 subwoofer?

The subwoofer should be placed 4 to 5 feet from the left and right front speakers. So my second piece of advice is to stay away from mounting the subwoofer in a corner. Corner placement has many advantages, but the main one is that the sub will produce more bass with less distortion there.

Can two subwoofers be connected together?

Option two: If a home theatre receiver has two wired subwoofer preamp outputs, you can connect two subwoofers to it directly (no RCA Y-adapter needed). Option three: If two or more subwoofers have both an input and an output, you can daisy link them together.

A bridged Acoustic Audio PSW250-6 subwoofer is what, exactly?

By bridging amplifier channels, a stereo pair of channels can be turned into a single mono channel. In car audio systems, bridging is frequently used to increase the power of subwoofers or larger full-range speakers.
