FREQ. RANGE

 

 

 

There is a huge overlap in the frequency range to really allow you to zoom in.

For general use 1 and 4.

Fig. 4:

1. frequency range from 10Hz to 2400Hz at +/-12dB

Fig. 5:

2. frequency range from 16Hz to 3300Hz at +/-12dB

The frequency control (Hz) varies the filter frequency over the range selected with the Frequency Range switches.

The two Frequency Range switches are used in combina- tion to select four frequency ranges. The switch positions are shown clearly on the Optimizer’s front panel. The ranges are:

1.

10Hz to 2.4kHz

2.

16Hz to 3.3kHz

3. 34Hz to 7.1kHz

4. 112Hz to 23kHz.

Sufficient overlap is provided between ranges so you can

select a suitable range that allows the Hz control to be used near the center of its travel. There is also enough overlap to equalize over the entire frequency range from 10Hz to 23kHz when the Dual mode is selected. In practice you will normal- ly only use the 1. and 4. frequency range, as the overlap is 2,288 Hz. Frequency ranges 2 and 3 can be used for fine tuning.
