APPLICATIONS AND PLACEMENT  
The most common BETA 98H/C applications and placement techniques are described below. Keep in mind that micro-  
phone technique is largely a matter of personal taste; there is no one “correct” microphone position.  
SAXOPHONE (see Figure 4): Clamp the microphone onto the bell of the saxophone, so the microphone is a few inches  
from and facing into the bell. This will produce a bright tonal balance while minimizing feedback and leakage.  
SOPRANO SAXOPHONE (see Figure 5): Clamp the microphone onto the bell of the saxophone and adjust the gooseneck  
so the microphone is facing the keys of the instrument, a few inches from the lower keys. This will produce a warm and  
full tonal balance. For a brighter tone, adjust the gooseneck so the microphone is facing into the bell, a few inches away.  
TROMBONE PLACEMENT (see Figure 6): Clamp the microphone onto the bell of the trombone and adjust the goose-  
neck so the microphone is facing directly into the bell, a few inches away. This will produce a bright tonal balance while  
providing maximum isolation.  
TRUMPET PLACEMENT (see Figure 7): Clamp the microphone onto the bell of the trumpet and adjust the gooseneck  
so the microphone is facing directly into the bell, a few inches away. This will produce a bright tonal balance while provid-  
ing maximum isolation.  
DRUM PLACEMENT (see Figure 8): Clamp the microphone onto the drum rim and adjust the gooseneck so the micro-  
phone is aiming a few inches above the drum head and an inch from the rim. This provides a full tonal balance.
