905 3-Band Parametric/Notch Equalizer (discontinued)

The 905 provides flexible equalization in a compact, high density format without sacrificing true, fully parametric operation of all three filter bands.

The bands each offer control of frequency, bandwidth (Q) and up to 15 dB of cut or boost. Each of the filters can be independently switched from standard reciprocal operation to "infinite notch" mode by simply turning the cut/boost switch a click-stop past maximum cut.

For shelving applications, the 905's high and low bands can be switched from peak/dip to shelving operation at the front panel.
