The SA-3052A has many applications. Some of these include:
• Sound System Equalization
• Monitor System Feedback Control
• Movie Theater Setup
• Home Theater Equalization and Setup
• Sound and Music Monitoring
• Component Testing
Sound System Equalization
Sound reinforcement systems, large or small benefit even more from carefully ap -
plied equalization. While only dynamite can really cure a really bad case of poor acous-
tics, equalization comes right after loudspeaker array design when it comes to getting the
most out of any speaker system in any room. If you set up in different venues night after
night, the SA-3052A can be the impartial judge that helps you make your sound consis-
tent, night after night.
The SA-3052A can work wonders on a home stereo. Most home stereos can benefit
from a bit of carefully applied equalization. Such equalization can go a long way towards
enhancing your listening pleasure. The SA-3052A can also be used to verify the perfor-
mance of various portions of the electronics in your system.
Whether you’re equalizing a home stereo, or a 100,000 watt concert sound system,
the basic technique is the same:
1. Listen
2. Measure
3. Balance speaker components and equalize
4. Listen
5. Trim equalization settings
Hi-Fi Equalization
Before attempting any corrective equalization, use the SA-3052A to make a prelim-
inary assessment of the situation. Use several microphone positions, finally drawing a
curve that represents the average of a representative sample of the positions. We recom-
mend no less than 3 different positions in a one to three foot cube around your listening
position.
Next, adjust the various level controls on the speakers themselves to smooth out the
mid- and high-frequency response. You can combat peaky bass response by trying vari-
ous elevations above the floor. Conversely, you can aid anemic bass response by using
floor or corner placement.
The name of the game here is to get things as “right” as possible without equalization.
Now it’s time to use the equalizer. Remember what we discussed in Section 2. It’s
important to remember to not try to equalize the dips in the overall response curves unless
they are quite shallow. Deeper dips may be due to a door, window, or other surface acting
