Crossover Setting (2 Channel Stereo Input Only)

The crossover control should be set in accordance with the size or bass output of the main/satellite speakers. The crossover control can be adjusted in 1Hz steps or in steps of 40Hz, 50Hz, 63Hz, 80Hz, 100Hz, 125Hz and 160Hz by pressing the Music or Impact buttons on the remote control. The crossover slope characteristic can also be adjusted in steps of 12, 18, 24, 30 or 36dB/ octave. Refer to the chart below as a guide to setting the crossover frequency control to the optimum position. Much will depend on the correct low frequency response of the main speakers, their position in your room and the room’s acoustic properties. Experimentation is advisable.

Sub-Sonic Filter

An adjustable sub-sonic (high pass) filter is provided to limit the reproduction of infra-sonic frequencies being produced below a usable frequency point. This enables the power to be delivered to the amplifier in the working range and nothing is wasted. The sub-sonic filter can be adjusted in 1Hz steps or in steps of 16, 20, 25 and 31Hz by pressing the Music or Impact buttons on the remote control.

EQ

There are five EQ modes to choose from:-

4 x pre-set options (which can be accessed by remote control during operation) Music, Movies, Dynamic & Impact. These can be set at any time in accordance with personal choice or the predominant operation of the system. They can also be selected and stored during the set up process from the menu system.

NOTE: The Graphic EQ cannot be adjusted when using the 4 x pre-set modes.

1 x User mode (FLAT). The FLAT (User) mode can be accessed only by remote control, during playback or from one of the 3 memory locations. Pressing the ‘movies’ button (for example) when already in the movie setting will select the FLAT mode. The FLAT EQ setting will change to ‘USER’ when any changes have been made to the graphic equaliser. The changes are made in the menu system when the USER EQ is selected. This will now allow the installer/user to access the 9 band graphic equaliser settings and make adjustments. +/- 6dB gain or cut can be obtained at the pre-set frequency divisions of 20Hz, 25Hz, 31Hz, 40Hz, 63Hz, 80Hz, 100Hz, 125Hz, and 160Hz.

These features can be used to provide a more accurate ‘in room’ balance and is particularly effective at counteracting room modes or positioning anomalies. A 1/3 Octave spectrum analyser or hand-held dB level meter, capable of accurately measuring down to 20Hz will be required to achieve optimum settings.

Phase

The Phase Control is used to synchronise any delay between the PLW-15 and main/satellite speakers. When the PLW-15 is in phase with the main/satellite speakers the sound should be full bodied. Sit in a normal listening position whilst adjusting the phase settings. When set correctly the location of the subwoofer should be almost undetectable. Experimentation is advisable. However it should be noted that in most cases the phase control should be set to 0 degrees, especially when using a digital A/V processor or A/V receiver amplifier. The phase angel can be adjusted in steps of 0, 45, 90, 135, 180, 225, 270, 315 degrees.

Night Mode

This setting limits overall dynamic capability and SPL by using a compressor type limiter. It can only be access via the remote control

Auto Off

This menu allows the user to select the auto turn off delay time. The time delay can be adjusted from 5 - 30 minutes in 5 minute intervals. If using the 12v trigger, the auto off function will not operate and the symbol in the display will change.

Mode Select

Here you can select either LFE or 2-Channel Stereo.

Lock Setting

If the lock setting is enabled, it will prevent any of the settings from being altered until it is disabled.

This allows for the efficient venting of air from the cabinet, reducing turbulence and distortion during operation. This design decision contributes to a cleaner, more controlled bass output, allowing the subwoofer to blend seamlessly with other speakers in a surround sound setup.

Customization is key in the PLW-15's design, offering users adjustable crossover and phase settings. These features enable users to finely tune the subwoofer to match the acoustics of their room, ensuring optimal performance no matter the environment.
