than in hard knee mode, and will therefore emphasize the slap at the beginning of the note

and reduce the boominess of its body. The MC6 also works well for tightening snare drums

and tom toms and can be used with drum machines to effectively alter the character of any

electronic drum sound.

For drum kit submixes (e.g., mixing multiple drum tracks to two tracks while using both chan-

nels of the MC6 for compression), consider backing off the RATIO (mid position) on each

channel to avoid an excess of cymbal "splattering." In larger multitracking systems, compress

the kick and snare separately. A further possibility is to heavily compress a stereo submix of

toms and leave the remaining percussives unaffected.

Raising a Signal Out of a Mix

Since reducing dynamic range increases the average signal level by a small amount, a single

track can be raised out of a mix by boosting its level slightly and applying compression. Start

with the middle RATIO position and a relatively low THRESHOLD setting. Adjust both controls

as necessary.

Compressors have also been used to bring vocals to the forefront of a mix in volume-restricted

studios (e.g. home studios). Start by adding a foam windscreen to the mic (if it doesn't have

one). Set the RATIO slider 3/4 to the right and the THRESHOLD slider slightly to the left of

center. With your mouth approximately 2 inches from the mic, sing the vocal part, but with

less volume than normal. Use phrasing to give the part some intensity. An equalizer (e.g., a dbx

242 Parametric Equalizer, dbx 20 or 30 Series Graphic Equalizers) or a vocal effects device

(e.g., reverb, delay, distortion) can be added to further define the performance.

Note: When compressing a stereo program with the MC6, the factors affecting a compression curve and the

actual RATIO and THRESHOLD settings are the same as those previously covered with reference to single chan-

nels of program material. However, it will generally be found that large amounts of compression are more

audible in a mixed stereo program than they might be on the separate tracks that were mixed to create the

program.

Smoothing out microphone levels

When distance is created between the vocalist and the microphone there will be a variation

in the signal level. Start with low compression to smooth out any variations. Limiting also bene-

fits intelligibility by allowing low-level input signals to be reproduced through the system at

higher volume.

Smoothing out musical instrument levels

Compression smooths out the variations of loudness among instruments. Using the MC6 can

also increase the instrument's sustain. Compress the instrument's output by adjusting the

RATIO and THRESHOLD settings to show between 8 and 12dB of gain reduction with a ratio

setting between mid-position and 3/4 to the right.

Speaker Protection

Compressors are frequently used to prevent excessive program levels from distorting power

amps and/or damaging drivers in a sound-reinforcement system (whether you're doing audi-

torium, church, or club sound engineering, or are a mobile DJ, or like to push the limits of your
