Kenwood AUDIO PROCESSOR manual Effects Processor Program Select / OFF Switch S4

FRONT PANEL CONTROLS

Incoming signals will have up to 20dB of compression introduced. The EQplus compressor circuitry contains a limiter that is preset at the factory. The limiter is set to limit the processed signals to 375 millivolts (-9 dB). When this level is reached the 1-st yellow LED on the bar graph will be on and the top Red (Limiting) LED will turn on. Additional increases in audio level, using either the Audio Input Gain Potentiometer or the Equalizer Potentiometers, will result in a small increase in output from the compressor’s circuitry. The good news is that the EQplus can produce high levels of compression while maintaining fidelity and very low distortion levels. The RF compressors in many radio’s have difficulty attaining high levels of compression with low levels

of distortions. RF compressors roll off the low end audio response of the signals they process. The net result of the EQplus compressor is up to 20dB of signal compression with very low distortion and little to no change in overall audio bandwidth. .

(12)Compressor / Downward Expander Downward Expander Level (DE LEVEL) POTENTIOMETER (R47)

This potentiometer works only if the Compressor / Downward Expander switch (10) is on. The Downward Expander removes unwanted audible sounds such as fan noise. The Downward Expander is operated by turning the DE LEVEL Control clockwise just to the point where unwanted sounds are removed.

(13)EFFECTS PROCESSOR PROGRAM SELECT / OFF SWITCH (S4)

This 3 position toggle switch is used to select one of two effects or to turn the Effects Processor off. When the Effects Processor is off the Effects Processor Delay and Level controls will not modify internal EQplus audio. The toggle switch in position 1 selects Effect 1. Effect 1 emulates dampening sound reflecting multiple times from a surface. The toggle switch in the position 2 selects Effect 2. Effect 2 emulates sound reflecting once from a surface.
