MODEL 263A

ÒessÓ sounds is usually lower than the rest of the vocal program, which means that sibilants receive less

compression than other parts of the vocal, causing them to sound louder. (A given mic can be another

aggravating factor.) But not all causes of excessive sibilance are electronic. The normal levels vary

widely form one voice to another and from one mic technique to another, and inherently harsh sibilants

often ruin an otherwise pleasing singing voice.

The annoyance of excessive sibilance increases when they are transmitted through a channel with limit-

ed dynamic range. Broadcast and recording engineers can face a major problem since hot high-frequen-

cy signal levels leave little headroom. And in large-scale sound-reinforcement applications, an extra 6dB

of headroom may require hundreds or thousands of extra watts of amplifier power, especially when com-

pression has increased the relative sibilant level. Proper control can prevent high-frequency clipping and

tweeter burnout and will enable higher sound-pressure levels without a large increase in amp output.

Equalization is often used in an attempt to cure these problems, particularly if they arise from heavy vocal

compression. But sibilants can occupy a fairly broad portion of the important 4-8kHz intelligibility band,

and a static EQ dip in this area will cause loss of articulation and dull sound. Equalization is not the solu-

tion.

Other Applications

The 263A has surprising uses in processing instruments. Any signals that have large high-frequency lev-

els without accompanying low frequencies can be modified; depending on the control settings, changes

can be subtle or obvious. Guitar plucks processed through the 263A will be mellower, with less pick

noise and less bite at the start of each note. ÒSpittyÓ brass will benefit likewise. Try both HF and

Broadband modes as you experiment.

We have noted that mid-settings of the slider give natural-sounding results and that far-right settings

cause exaggerated effects. But on synthesizers and drums, go ahead and try extreme settings, and

experiment to find new effects on other instruments.
