The Rane ME 15S microGraphic Equalizer is a two-channel, 2/3-octave design with 20 mm sliders in a single rack space unit. It features a Range switch for high slider resolution in the +6 dB mode, equivalent resolution to 45 mm sliders found on the DEQ 60L. The +12 dB mode provides a wide range of control over system audio.
The active filter sections feature Ranes innovative constant-Q (constant bandwidth) design. Constant-Q 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 switches, include an overall Level control for each channel as well as overload indicators. 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" connectors or by tying the ring to the sleeve on TRS type plugs.
The ME 15S replaced the ME 15B with a new internal universal switching power supply (100-240 VAC). All other features are the same.
