General Description

The Rane ME 30B is a single channel, 1/3-octave contstant Q micrographic equalizer. The ME 30B utilizes compact 20 mm sliders, and features a Range switch for high slider resolution in the ±6 dB mode. The ±12 dB mode provides a wide range of control over system audio.

The active filter sections feature Rane's innovative constant-Q (constant bandwidth) design. This means the bandwidth of each individual filter is guaranteed to be narrow enough to prevent unwarranted interaction between filters, yet wide enough to produce exactly the type of correction curve demanded by even the most unusual acoustic surroundings. This differs dramatically from conventional designs of the past, encumbered with the unfortunate characteristic of changing bandwidth when changing boost/cut amounts.

Front panel controls and indicators, aside from the sliders and the filter range switch, include an overall Level control as well as an Overload indicator and a passive Bypass switch. The rear of the unit provides both 1/4" Tip-Ring-Sleeve and XLR connectors for each of the Inputs and Outputs. The Inputs and Outputs are fully actively balanced. Unbalanced sources may be connected through the use of either "mono" 1/4" TS connectors or by tying the ring to the sleeve on TRS type plugs.
