Speaker Adjustment

The MC-553 has two pivoting tweeters and a +3/0/-3 dB gain switch. To select a setting on the gain switch simply slide the switch up, down or position it to the middle to obtain the desired sound. Depending upon your listening area, you may find the sound more pleasing to point the tweeters in a particular direction. If additional treble is desired, simply point the tweeters towards that area; if less treble is required, point the tweeters away.

Gain Switch Settings:

-3dB	Reduces the loudness
	of the treble frequencies
0dB	The treble frequencies)
	remain at a neutral level
+3dB	Increases the loudness
	of the treble frequencies

Break In Period

Allow several hours of listening time to adequately break-in the speakers. As the speakers break-in, the driver suspension will loosen. The result of break-in will be an increase in low frequency response, improved definition, and increased clarity and detail.
