ME 60S
microGRAPHIC EQUALIZER
Data Sheet-1
General Description
e Rane ME 60S Stereo Constant-Q Equalizer is a two-
channel, ⅓-octave design, housed in a two 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 larger
models. e ±12 dB mode provides a wide range of control over
system audio.
e ME 60S evolved by combining two ME 30 equalizers
in one unit and then embellishing with two adjustable band-
limiting lters on the low and high end. ough consuming only
12 watts of power, a Power switch is added to the ME 60S (the
ME 30S consumes 7 watts and does not have a Power switch).
e active lter sections feature Rane’s innovative constant-Q
(constant bandwidth) design. Constant-Q means the bandwidth
of each individual lter is guaranteed to be narrow enough to
prevent unwarranted interaction between lters, yet wide enough
to produce exactly the type of correction curve demanded
by even the most unusual acoustic surroundings. is diers
dramatically from conventional designs of the past, encumbered
with the unfortunate characteristic of changing bandwidth when
changing boost/cut amounts.
e adjustable lters are useful to band limit the audio
signal. For instance, restricting high frequencies to match the
incoming signal usually produces the most quiet system. And
a common use for the Low Cut Filter is limiting the signal go-
ing to 70-volt speaker systems. Often low frequencies saturate
the loudspeaker transformers. Restricting these signals greatly
improves system intelligibility. Full bandwidth use requires posi-
tioning both sliders to their lower limits. is eectively removes
the lters and guarantees 20-20 kHz ±0.5 dB performance.
Front panel controls and indicators include an overall rotary
Level control for each channel as well as Overload indicators.
Passive pushbutton Bypass switches feature LED indicators,
avoiding ambiguity by being on when the unit is Bypassed. (A
passive Bypass switch requires no power to operate. is allows
completion of the audio path should power fail in the ME 60S.)
Inputs and Outputs are electronically balanced designs,
capable of unbalanced operation when required. ey accept
and drive all possible signal levels into normal load impedances.
Balanced applications choose between the XLR or ¼" Tip-
Ring-Sleeve connectors. Unbalanced sources also may tie to the
ME60S through mono ¼" connectors (no ring connection).
