Product Description
The Trident CB9066 is a 3 band 80 series style parametric EQ with sweepable hi and lo pass filters. Features bypass, bandwidth control and 16 dB of boost/cut on each of the three parametric bands.The units designer John Oram discusses it here:
"This was my first product designed for the original Trident company when I was hired as a design consultant in 1974. It's discrete using tons of tantalum capacitors that the company had inadvertently over ordered. I created a unique frequency sweep technology giving a 10:1 range with a single gang pot. Totally class A with BC413 and BC416 devices in the main running on a +45 volt rail. Trident liked the design and the fast turnaround and I continued there on a project by project basis for 14 years. Designed long before I did the Series 80 circuits, it's interesting how that sonic footprint carried through in my later designs."
