Control Functionality

Phase.

Adjusts the phase of the subwoofer output relative to your main speakers from 0 to 180 degrees in 5 degree steps.

Level.

This decreases or increases the subwoofers volume relative to the main speakers.

Slope.

Switches the Low Pass Filter slope between 12 (shallow) and 24dB per octave (steep). This can be set to allow the best integration with your other speakers. Frequency and slope only apply to the Left and Right line level inputs. The LFE inputs are fixed at a cut off frequency of 200Hz and a slope of 24dB/Octave so that the settings do not interfere with the bass management setting on an external A/V receiver.

Frequency.

Increases or decreases the internal low pass filter cut off frequency in the subwoofer between 40Hz and 140Hz so that it integrates smoothly with the main speakers. It is only applied to the Left and Right inputs and is not applicable to the LFE input where it is assumed an external surround sound processor is controlling the bass management externally

Subwoofer/Satellite Integration : Correct

Subwoofer/Satellite Integration : Too Low. Increase the frequency.

Subwoofer/Satellite Integration : Too High. Reduce the frequency.

Music and Cinema Setting

The Music and Cinema Switch changes the internal EQ settings on the Reference Series 208 subwoofer. Music is a flat response as shown below. Cinema adds a mid-bass boost of 6dB.

This EQ is applied for both the Left and Right and the LFE inputs.

MUSIC Standard Flat Response
