Ashly MQX-2150 Guide de démarrage rapide

MQX-2150

The graphic equalizer shall be stereo (2 channels). Each

channel shall consist of 15 bands centered on standard

ISO frequencies at intervals of 2/3 octave and covering

a frequency range of 25Hz to 16kHz. Individual bands

shall be activated by linear slide faders with a 25mm

travel, and a tactile center detent. The range of equaliza-

tion per band shall be switchable between ±15dB or

±6dB.

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 -96dBu and

SMPTE intermodulation distortion or THD shall be

less than 0.01% at +20dBu. Input impedance shall be

20k ohm balanced, 10k ohm unbalanced. Output

impedance shall be 200 ohm balanced, 100 ohm unbal-

anced. Inputs and outputs shall be active (tranformer-

less) balanced type on both XLR and 1/4 phone jacks.

Individual filters shall be Wein-bridge type and con-

nected in a summing circuit optimized for minimum

filter interaction and constant bandwidth at any slider

setting. Boost and cut characteristics shall be fully sym-

metrical, 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 fre-

quency and shall be non-adjustable to insure long term

accuracy.

The equalizer shall also include an 18dB per octave

high pass filter at 20Hz, internally selectable. A green

signal presence and red clip indicators shall show criti-

cal operating levels. Input gain shall be adjustable over

minus 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 90-

125VAC, 50-60Hz, 10W. The unit shall be an Ashly

Audio MQX-2150.
