The ME 60is a dual channel, 30 band, 1/3-octave constant-Q equalizer, housed in a two rack-space unit. The unit evolved by combining two ME 30B equalizers into one unit with two adjustable band-limiting filters added to enhance each channel's versatility.
The active filter sections feature the GE 30's interpolating 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. Aside from being a constant-Q device, the ME 60also provides "Interpolating" performance. This means that when two adjacent bands are boosted or cut to the same level, the response of the equalizer peaks at a frequency centered between the filters. Interpolating performance allows effective control between ISO centers.
The front panel controls and indicators of the ME 60 include an overall rotary level control for each channel as well as clip indicators. Passive pushbutton bypass switches feature LED indicators for immediate indication of status. A passive bypass function allows restoration of the audio path should power fail in the unit. Inputs and outputs are electronically balanced designs, but can function unbalanced, with a choice between XLR, 1/4" TRS phono or RCA coaxial connectors. They accept and drive all possible signal levels into normal load impedance.
