IVER EQUALIZER SETTING FIGURE 17 Adjusting the Low Cut Filter High Pass The low cut or high pass filter allows all frequencies above its cutoff point to pass from filter input to filter output without attenuation while frequencies below its cutoff point are attenuated See Figure 18 The cutoff point is defined as the frequency at which the signal has dropped 3 dB relative to the flat bandpass region Below the cutoff point the filter exhibits increasingly more attenuation as the frequency level drops The rate at which this attenuation occurs is expressed in decibels per octave dB oct The UC4 Receiver has a one pole low cut filter of 6 dB per octave Low ocut filters are used to attenuate the audio signal when low frequency noise or excessive proximity effect is pres ent For example the low frequency vibration caused by wind footsteps and vehicular traffic can be transmitted through microphone stands to the microphone and from there to the sound system These low frequencies typically ranging from 5 to 80 Hz are generally not desirable FULL CW MARCAD Wy A B POWER o 0 O18 o SQUELCH RF AUDIO LOWBAT GROUP 5096 ROTA AMPLITUDE dBV on A N o 20 100 1 000 5 000 FREQUENCY Hz ADJUSTING THE LOW CUT FILTER FIGURE 18 Adjusting for High Frequency Shelving The fixed frequency equalizer produces a 6 dB boos
