Optimizing settings/Troubleshooting

Level

General tips

Check it out Try different subwoofer positions and settings, before you finally choose a setup.

Note down settings When looking for the best subwoofer position in the room, note down the ideal setting you found for a position. When moving the subwoofer between two positions you will be able to set the subwoofer to the same configuration as found before.

Vary the listening music When experimenting to find the optimal settings, use a couple of music tracks with repetitive bass across a large spectrum. The tracks should be sufficiently different from each other and each should cover a wide bass-range. Musical instruments, such as a double-bass, bass guitar, church organ, etc. covering a wide spectrum in the bass region and above, are very suitable as these depend on accurately balanced subwoofers and main speakers.

Verify changes Although in general it is best to make adjustments in the sequence outlined below, note that changing one setting may influence another. For example, finding the right setting for phase may result in having to decrease gain, even if this was set correctly before. It is recommended that you double-check the previous settings before moving on to the next one. Obtaining the best integration of the subwoofers generally involves a considerable amount of repeated fine-tuning.

Volume (GAIN)

With the GAIN control you can adjust the relative volume level of the subwoofer to the main speakers of the system:

XPlay the same track a couple of times, adjusting the level so that the instrument sounds homogenous across its range.

If you find that at certain specific bass tones the response is either too loud (bloated sound) or soft (thin sound), it may be that you have to experiment further with the location of the subwoofer and/or the cross-over settings.

XRefer to the sections “Positioning the subwoofer” on page 12 and “Cut-off frequencies” on page 14 for further information.

Note: When using multiple subwoofers, ensure that all settings such as level, cut-off frequency, phase and LF extension are identical. Use the LFE and Slave mode options to ensure that all subwoofers operate on the same settings (refer to chapter “Multiple subwoofer connections” on page 8).
