a lot of power). Distortion may also originate with a bad signal source (tape, microphone, etc).

Low Frequency Distortion

The 5 inch driver will not reproduce tones lower than 200 Hz. If the

speaker begins to distort, reduce the low frequencies by

adjusting the LOW tone control. As a monitor the

HOT SPOT does a great job in conjunction with

the house stack where the low frequencies are

reproduced.

MAXIMIZING GAIN

Figure 1.1

Figure 1.1 represents the worst possible case of

gain limiting; the microphone is pointed directly at

the speaker. Any increase in volume will instantly

produce feedback. As little as

of the amplifier's pow-

1000

er may be available; with a 100 watt amplifier, that's only

of a watt. In Figure 1.2 , the distance between the microphone

and the speaker has increased to 500 feet, allowing 100 percent gain (all 100 watts of power may be

utilized without producing feedback). Of course, these are extremes, but they illustrate the importance of speaker and mi-

crophone placement in determining the gain of the system. In most cases it's not possible to locate the microphone 500

feet from the speakers.

The challenge is to position the speakers to adequately cover the listening area while positioning the microphone to maxi-

mize the gain.
