ITI MEP-130 EQ Pair (Vintage)

EQ controls feature:

• Stacked knobs with continuously variable frequency and bandwidth controls ('Q')
• Single knobs with +/- 12 db attenuation.

Overlapping frequency controls are:

• 15 to 800 Hz
• 150 Hz to 8KHz
• 420 Hz to 25.6 KHz 

These are the original parametric EQ! Designed and built by Burgess MacNeal (Sontec) and
George Massenburg (GML); two outstanding engineers who wanted to create an equalizer that did not rely on inductors and switches. The result was the parametric equalizer, with the novel ability of bandwidth control, which first appeared in 1968. 

Together, MacNeal and Massenburg designed the ITI MEP-130 (originally as a console module), before they started their own separate companies. Both of the classic Sontec and Massenburg EQ’s owe their heritage to the MEP-130. These units are very rare and seldom available. Uses ±36VDC rails for lots of headroom.
