Starlet Owner’s Manual | Page 11 |
A few notes, based on our experience:
1.It is best to set these levels on recessed volume controls, such as those on the SpeakerCraft BB series of amplifiers, as this adjustment is a one time, “set and forget” procedure.
2.All pink noise should be identical, but it isn’t. The noise on SpeakerCraft’s
3.Digital voltmeters can be problematic with pink noise. This is because pink noise “pumps” up and down a few dB and, even with an averaging meter, it can be hard to set the level to a medium of 0.5. For instance, we get readings of 0.45 to 0.55 when the level is set correctly. Also, many AC DMM’s do not have a low voltage range.
4.Radio Shack has a low cost ($24.95) voltmeter that has a 10 volt AC range, and works very well in this application.
SUBWOOFER ADJUSTMENTS
All Starlets are designed for high end systems where subwoofers are required. Unlike the midrange and tweeter settings, each room is so different in bass response that it is best to set the controls by ear. Here is our recommended starting point, based on the controls for SpeakerCraft’s
Start with the volume control at about 9 o’clock, the boost at about 10 o’clock, the frequency control at 10 o’clock and the phase control at 0˚. (See Diagram 21) Slowly advance the volume until you hear a good balance. Here it helps to take the time to lis- ten to several tracks in several locations in a room. If it is not possible to get bass without excess “boominess”, rotate the boost back counterclockwise. If there are areas of the room where the bass seems to totally drop out, experiment by moving the phase to 180˚.
