[TenTec] Good Mike Technique

[Bob McGraw - K4TAX]

I can agree with Jim on this.

Proper use of compression  {emphasis on "proper} does raise the average 
audio level.  Excessive compression can cause a "pumping" sound. 
Compression with incorrect attack and release times, largely defined by the 
program content, can also make things better or worse.    Compressors with 
automatic variable ratio attack and release times plus variable input to 
output ratios do a really nice job to hold the audio level up and do not 
artificially color the sound.  The Teltronics LA-2A is a good example.  Also 
the CBS Labs VolumeMax  is another good one.
