MQX-2310
The graphic equalizer shall be stereo (2 channels).
Each channel shall consist of 31 bands centered on
standard ISO frequencies at intervals of 1/3 octave
and covering a frequency range of 20Hz to 20kHz.
Individual bands shall be activated by linear slide
faders with a 25mm travel, and a tactile center
detent. The range of equalization per band shall
be either ±6dB or ±15dB selected via a 2-position
switch.
The equalizer shall have a gain of unity with all
sliders centered, and shall have a maximum in/
out level of +23dBu. Frequency response shall be
±.25dB 20Hz to 20kHz. Hum and noise shall be at
least -94dBu and SMPTE intermodulation distortion
or THD shall be less than .01% at +20dBu. Input
impedance shall be 20k ohm balanced, 10k ohm
unbalanced. Output impedance shall be 200 ohm
servo-balanced, 100 ohm unbalanced. Inputs shall
be active (tranformerless) balanced type on both
XLR, 1/4”, and euroblock connectors. Individual fil-
ters shall be Wein-bridge type and connected in a
summing circuit optimized for minimum filter inter-
action and constant bandwidth at any slider setting.
Boost and cut characteristics shall be fully symmet-
rical, with the filter being electrically removed from
the circuit in the center (flat) position. Individual fil-
ters shall be accurate to within 3% of indicated cen-
ter frequency and shall be non-adjustable to insure
long term accuracy.
The equalizer shall also include an 18dB per octave
high pass filter at 40Hz, equipped with a bypass
switch. Green signal presence and red clip indicators
shall show critical operating levels. Input gain shall
be adjustable over -infinity to +6dB, and an overall
EQ bypass switch shall be included. The equalizer
shall weigh 8.5 lbs net and mount in a standard 19”
rack using 2 spaces (3.5” high). The power require-
ment shall be 100-240VAC, 50-60Hz, 24W. The unit
shall be an Ashly Audio MQX-2310.
