Ashly MQX-1310 User Manual

MQX-1310

The graphic equalizer shall be monaural (1 channel).
It 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 -92dBu and SMPTE intermodulation distortion or
THD shall be less than .01% at full output. Input
impedance shall be 20k balanced, 10k ohm unbal­anced. Output impedance shall be 200 ohm balanced,
100 ohm unbalanced. Inputs and outputs shall be
active (tranformerless) balanced type on both XLR, 1/4
phone jacks and barrier strip terminals. Individual fil­ters shall be Wein-bridge type and connected in a sum-

ming circuit optimized for minimum filter interaction
and constant bandwidth at any slider setting. Boost and
cut characteristics shall be fully symmetrical, with the
filter being electrically removed from the circuit in the
center (flat) position. Individual filters shall be accurate
to within 3% of indicated center frequency and shall be
non-adjust-able 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 6.5
lbs net and mount in a standard 19 rack using 1 space
(1.75 high). The power requirement shall be 90­125VAC, 50-60Hz, 10W. The unit shall be an Ashly
Audio MQX-1310.
