2-channel graphic EQ, 1U, 2/3 oct., constant Q, 2x15 bands, +12/-12dB, low and high cut, XLR, 6.3mm jack. The Rane ME 15S is a 2/3 octave Constant-Q dual-channel graphic equalizer. Housed in a 1U rack unit, it features compact 20mm faders. It offers two operating modes: (+12 to -12) and (+6 to -6), which can be switched using the RANGE button on the front panel for each channel separately. The active section of the ME15S consists of filters with a constant bandwidth (Constant Q). The bandwidth of each individual filter is carefully selected to prevent unwanted interactions between filters while being wide enough to create the precise correction curve needed, even in challenging acoustic environments. The bandwidths are chosen meticulously to ensure that two adjacent filters can be used to achieve a curve with a peak between the central frequencies of these two filters. This sets this equalizer apart from many conventional designs of the past, which often suffer from bandwidth changes with filter parameter adjustments. In addition to the 2x15 sliders, the front panel includes controls for overall output level for each channel separately, an overload indicator, and two passive BYPASS switches. The rear panel features balanced XLR and TRS (6.3mm jack) inputs and outputs.
