1.Stand-by / On Indicator

The LED indicates whether the unit is in stand-by mode or operational.

2.Crossover Frequency Control

The crossover frequency control only operates when the low pass filter switch (refer to section 3.) is in the ‘In’ position. The crossover frequency control is used to set the upper frequency limit (low pass) of the RS W12. The crossover control should be set in accordance with the size or bass output of the main/satellite speakers. 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 and their position in your room. Experimentation is advisable.

Type of main speaker

Crossover control setting

Large floor-standing speaker

40-60 Hz

Small floor-standing speaker

50-70Hz

Large stand-mount/ bookshelf speaker

50-80 Hz

Small stand-mount/ bookshelf speaker

60-90 Hz

Small satellite speaker

80-160 Hz

3.Low Pass Filter Switch.

When set to the ‘In’ position the crossover frequency control (section 2) is activated and can be adjusted from 40Hz to 120Hz using the crossover frequency control. When set to the ‘In’ position it can be used with an amplifier that does not have a dedicated sub-woofer or LFE output, such as a stereo 2-channel amplifier. If the amplifier or A/V processor has a dedicated LFE or sub-woofer output, the Low pass filter switch should be set to the ‘Out’ position. The low pass filter will then be set by the amplifier internal filter. This should be set in accordance with the amplifier or A/V processor user guide.

4.Phase Control Switch

The Phase Control is used to synchronise any delay between the RS W12 and main/satellite speakers. When the RS W12 is in phase with the main/satellite speakers the sound should be full bodied. Sit in a normal listening position whilst adjusting the phase switch. Help from another person may be required in order to do this easily. When set correctly the location of the subwoofer should be almost undetectable. Experimentation is advisable in order to achieve optimum results. However it should be noted that in most cases the phase control switch should be set to 0 degrees, especially when using a digital A/V processor or A/V receiver amplifier.
