[. . . ] Applications Ideal applications for the HR11C include amplifying acoustic instruments, controlling podium or pulpit microphones or processing a microphone signal with a line signal. If the HR11C is put with the ROLLS HR100 Power amplifier it makes a useful P. A. engine with a great deal of control as might be useful in auctions, rodeos, etc. . Since both inputs can be used at the same time one can be used for music the other for voice such as in aerobics studios and square dance calling. Using the HR11C Compressor After plugging the signal source into the input jack, push the switch to the right of the compressor knob. With the knob at 0 dB it works as a limiter, supplying no gain reduction below its threshold. As you rotate the knob toward 10 dB there is more gain for helping maintain a more constant output level as the input signal is varied. Notch Filter The notch filter is useful for suppressing the first feedback fundamental. The sound system is adjusted until there is a "threshold" of feedback, then press the button to the right of the notch control and adjust the control until the point where the feedback goes away. 10 Band Equalizer The equalizer is mainly for adjusting the tone of the sound source for taste or to cut noise.
