Frequently Asked Questions - SW8 Niles

How do I connect the subwoofer to my receiver?

Use a line-level RCA cable from the receiver's subwoofer output to the subwoofer's LFE input. If your receiver lacks a dedicated sub out, connect speaker level wires from the receiver's speaker terminals to the subwoofer's speaker level inputs.

What is the best placement for the Niles SW8?

Place the subwoofer in a corner or against a wall for maximum bass output. Avoid placing it in the center of the room to reduce cancellations. Experiment with location to achieve balanced bass response.

Why is there a humming noise from the subwoofer?

Hum is often caused by a ground loop. Try plugging the subwoofer into a different outlet, use a ground lift adapter, or ensure all audio components are on the same electrical circuit.

What crossover frequency should I set?

Set the crossover frequency to match your main speakers. Typical settings are 80-120 Hz. Start at 80 Hz and adjust up if your speakers struggle with low frequencies.

What does the phase switch do?

The phase switch (0° or 180°) adjusts the polarity of the subwoofer output. Use the setting that yields the fullest bass at your listening position, usually determined by ear or with a test tone.

How do I power the subwoofer on and off?

The subwoofer has an auto on/off feature that activates when it detects an audio signal. It will enter standby mode after no signal for several minutes. You can also use the manual power switch on the back panel.

Can I use the subwoofer outdoors?

The Niles SW8 is designed for indoor use only. Outdoor exposure to moisture or extreme temperatures may damage the electronics and cabinet.

What is the warranty period?

Niles typically offers a 5-year limited warranty for their subwoofers. Check your purchase documentation or contact Niles support for exact terms.

How should I clean the subwoofer?

Clean the cabinet with a soft, dry cloth. Do not use abrasive cleaners, solvents, or water, as they may damage the finish. The grille can be vacuumed gently.

Where can I find the user manual for the SW8?

The user manual is included in the box. You can also download a PDF from the Niles website or access it via the product page on notice-facile.com.

FEATURES AND BENEFITS

High power, high efficiency digital amplifiers provide tremendous dynamic range for clear and defined deep bass response. The SW8 features a 1200W dynamic digital power amplifier and the SW6.5 features an 800W dynamic, digital power amplifier. Both provide high output and high efficiency, with less heat produced compared to conventional analog power amplifier designs.

High power, long throw active woofer drivers feature black anodized aluminum cones which provide superior rigidity compared to conventional paper cone designs. This ensures that during extended passages of high level deep bass output, the driver cone resists breakup, which provides clean, low distortion sound that brings your music and movies to life!

Dual anodized aluminum cone passive radiators provide additional driver pistonic area, and their combined output along with the main active driver equals that of a larger single active driver. In other words, these passive radiators allow them to move a lot more air, bringing more rich, deep bass to you from a smaller, more compact subwoofer that is easy to blend into your home's décor.

Installation flexibility includes the option for easy wall or ceiling mounting utilizing the OmniMount 30.0 ST-MP. This gives you the ultimate flexibility for installing this compact subwoofer.

Advanced configuration flexibility includes stereo (L/R) line inputs along with unbuffered stereo pass-through line outputs, which also allows you to cascade the output up to three additional subwoofers. The C5-A2 port (RJ-45 connector) provides the option of an easier and less expensive wire run using CAT-5 cable from the A/V receiver or processor to the subwoofer via an optional Niles CAT-5 Balun adapter using standard CAT-5 wiring. A wireless input port provides an additional input connection option via the available Niles FG01672 wireless transmitter/receiver system, eliminating the need for a wired signal connection to the subwoofer.

Adjustable low pass frequency, phase and level controls allow precise main speaker and subwoofer matching and blending. The adjustable frequency control (50 Hz\~150 Hz) features a bypass position, eliminating low pass filtering within the subwoofer. The variable phase control ( 0^ 180^ ) allows precise phase matching with the main speakers.

Auto Sense feature provides energy efficiency by putting the subwoofer into standby mode when no audio signals are input to the sub, and can be disabled for “always on” mode. An LED indicator provides confirmation of the subwoofer’s power state.

PLACEMENT

THE BOUNDARY EFFECT

With their compact dimensions, the Niles SW8 and SW6.5 subwoofers provide a wide range of placement options, including wall or ceiling mounting via an optional mount kit.

When considering where to place a subwoofer in a particular space, note that the “boundary effect” can provide increased acoustic output due to the reinforcement effects when the subwoofer is placed on the floor, by a wall or in a corner.

Generally, when placed in or near a corner, the acoustic output of the subwoofer is substantially greater due to the boundary effect's acoustic gain. This provides two benefits. First, as the acoustic output of the sub (as perceived at the prime listening position) is greater than in free-space (away from the walls, floor and ceiling), the subwoofer doesn't need to "work" as hard, which results in lower distortion. Second, the gain provided by the boundary effect serves to increase the subwoofer's available dynamic range, for increased deep bass output at elevated listening levels.

Generally, corner placement provides the greatest acoustic reinforcement. However, corner placement is not always optimum, and some experimentation may be necessary in any particular room.

If the subwoofer is placed far away from the main speakers, there may be an audible discontinuity between the low bass sound from the sub and the wider upper range sound from the main speakers. This becomes even more critical when using compact main speakers, where a higher crossover frequency is often necessary. At a high crossover frequency (150 Hz), there is a much greater chance of audible main speakers and subwoofer discontinuity, with the subwoofer's output becoming distinctly audible as a sound source.

Ideally, the best subwoofer placement in any given space will reward the listener with a high quality full range acoustic experience, with the subwoofer itself seamlessly blending in with the main speakers, and not audible as a sound source itself.

CONNECTION AND CONTROLS (CONTINUED...)

AC VOLTAGE OPTION

The AC voltage option has been factory configured 100\~120 V\~.). Should the AC voltage need to be changed to 220\~240V\~ loosen the screw on the protective cover, slide the cover away and the slide switch can be adjusted. Make sure to replace the protective cover when done. Only make this adjustment if the subwoofer will be connected to a voltage supply of between 220-240 VAC @50Hz.

INPUT/OUTPUT CONNECTION OPTIONS

For most system configurations, connect the A/V surround receiver or processor's Sub output to the L/LFE input (3).

For a stereo music system where the stereo source features pre-amp level outputs, connect both L/LFE and R inputs (3).

The pass-through stereo outputs (4) can be connected to a stereo power amplifier if needed. The pass-through L/LFE output can be connected to another subwoofer if desired.

Niles offers a range of Balun adapters that allow audio signal transfer over standard Cat-5 network cabling. Compared to coaxial audio interconnect cable, which can be costly over long runs and more difficult to route through walls, Cat-5 cabling is usually less expensive on a per-foot basis, and is easier to route through walls. Connect a suitable Niles Balun receiver/adapter to (10) to use this option.

Niles also offers a wireless audio transmitter/receiver system, which eliminates the need for audio signal cable connection to the subwoofer. Connect the wireless receiver to the wireless port (11) to use this option. Refer to the wireless system's instruction manual for further instructions.

CONTROLS

Turn-on Mode (6)

The Turn-on Mode provides the option to have the subwoofer in “always on” mode or to have the subwoofer ordinarily in standby mode unless an audio input signal is present. The Signal Sense mode automatically detects the presence of an audio input signal and brings the subwoofer out of standby mode. This is the most energy efficient mode. With either mode, the main Power switch (2) must be set to On. The default position from the factory is “Signal Sense”.

CONNECTION AND CONTROLS (CONTINUED...)

CONTROLS (CONTINUED...)

Frequency (7)

Adjust this control to match the characteristics of the main speakers. For applications where full-range signals are sent to the subwoofer, the 100 Hz Normal setting will usually produce the best results. If the main speakers are compact, their more limited lower frequency range may necessitate a higher subwoofer frequency setting. For systems with large, full range main speakers that can reproduce deep bass, lowering the frequency setting may be desirable. If the audio source (A/V surround pre-amp, processor or receiver) is equipped with a bass management/bass re-direction function that includes low pass filtering for the Sub output (which is almost always the case), set the Frequency control on the Niles Subwoofer to Bypass to prevent cascaded low pass filtering.

Phase (8)

Depending on the subwoofer's physical placement and the acoustical characteristics of the main speakers, achieving optimal blend may necessitate phase adjustment. Upon initial installation and setup, set the control to the 0^ (in-phase) position, and listen to a variety of program material, including music selections as well as movie soundtracks. Experiment by adjusting the Phase control in small increments until the best combination of low bass sound quality and matching (blending) with the main speakers is achieved.

Level (9)

Initially set the control to the lowest position, and while listening to music and film content, slowly adjust the control upward until an even bass response is achieved. Many A/V receivers and surround processors include a built-in noise generator for channel level balancing, and by using a sound pressure level meter, it's possible to quickly find the optimum subwoofer level setting. When using an SPL meter to match subwoofer output level with the main speakers, it's important to make measurements at the principal listening position. The 0dB setting (mid-point) is often the best setting, and further subwoofer channel level fine-tuning adjustments can be made via the A/V surround processor or receiver's channel level adjustment control.

FINISHING THE INSTALLATION

If the subwoofer is to be wall or ceiling mounted, the four cabinet feet can be removed if desired.

REMOVING AND INSTALLING THE GRILLE

Ordinarily, the grille need not be removed. However, some prefer the visual aesthetic achieved with the grille removed. Either way, the acoustic quality will be the same. To remove the grille, grasp the grille edges with both hands and gently pull outward. To re-install the grille, gently press on the grille corners to secure the grille to the cabinet.

CLEANING

Use a dampened soft cloth to clean the cabinet. If the grille becomes dusty or dirty, use a vacuum cleaner attachment with a soft brush head.
