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.
