GQ-231
Tile graphic equalizer shall be monoaural 11 rhnnnrl). It shall consist
of 31 bands centered on standard ISO irequenefes at Intervals of 1/3
octave and covering a frequency range of 201 tz to 20kKz. Individual
bands shall be activated by liiKar slide faders with a 45nim travel,
metal actuator shafts and a laellle center clelent. Tbr range of equal­
ization per band shall be cither ¿€dB or il5dD selected \ia a 2-posl-
lion switch. The equalizer shall have a gain of unity with all sliders
centered, aixl shall have a maximum In/oul le\*el of 426dBV.

The graphic equalizer sliall be stereo |2 channels). Each channel
sliall consist of 31 hands centered nn standard ISO frequencies at
intervals of I /3 octave and covering a frequetKy^ range of 20Hz to
20kHz. Irtdhldual bands shall be activated by linear slide faders wltli
a 45mm travel, metal actuator shafts and a tactile center detent. Ilie
range of equalization per band shall be either ±6dB or i 15dB selected
via a 2-posilion switch. The equalizer .shall Itave a gain of unity with
all sliders centered, and shall have a maximum in/oul level of
■»26dBV. Frequency response shall be ±.25dB lOHz lo20kKz. Hum
