Niles Audio OS7.3, OS5.3, OS6.3 manual Listening at Higher Volumes, Cleaning, OPeration

1.Stand halfway between the loudspeakers.

2.Play some music with the amplifier or receiver set to Mono.

3.Listen to the richness of the bass and the loudness of the sound.

4.Turn off the amplifier and reverse the connections on one amplifier channel only.

5.Repeat the listening test with the same volume control setting. When the sound has a richer bass and is slightly louder, the loudspeakers are working together or “in-phase.”

OPeration

Listening at Higher Volumes

Outdoors there are no walls to reflect and contain the sound. It requires more power to achieve a reasonable volume of sound outside than it does indoors. You also frequently find yourself very far from the loudspeakers. It is possible to turn the volume so high that the amplifier runs out of power. This creates “clipping” distortion.

Clipping distortion makes treble sound very harsh and unmusical. When you hear harsh sounding treble from any good loudspeaker indoors or outdoors, turn the volume down immediately! Those harsh sounds are masking some much more powerful ultra-high-frequency sound spikes which will quickly damage any fine loudspeaker.

Cleaning

Clean the OS loudspeakers with a dampened soft cloth or paper towel. If the loudspeaker is mounted high up on a wall or ceiling, use a broom to gently brush it off. Hosing off the loudspeaker is not recommended, as the tweeter is a precise mechanism which might be damaged by a high-pressure stream of water.
