Filter Frequency
For each filter, you can set the center frequency of the band to any frequency between 20 Hz and
20 kHz, and the result will be displayed in Hz (or kHz).
Test Tone Level
Use the Test Tone Level control to set the output level of the sine wave test tone used to calibrate
the parametric EQs. There is only a single Tone Generator, even though the control appears in
duplicate under the options for each filter. The Test Tone Generator output level can be set to
High -85 dB, Medium - 75 dB, Low - 65 dB, and Off for use with external calibration signal sources.
Test Tone Frequency
Use the Test Tone Frequency control to set the output frequency of the sine wave test tone used
to calibrate the parametric EQs. There is only a single Tone Generator, even though the control
appears in duplicate under the options for each filter. The Test Tone Generator output frequency
can be set to any frequency between 20 Hz and 20 kHz, and the result will be displayed in Hz (or
kHz).
Note: you may notice that the test tones are not absolutely pure continuous sine waves - and
may include audible ticking noises at certain frequencies. While audible, these noises are
simply artifacts of the program code used to generate the test tones; they do NoT significantly
affect the energy distribution of the test tones, and have no significant effect on measurements
performed using the test tones.
